`Response to Amendment
`
`1. The present application is being examined under the pre—AIA first to invent provisions.
`
`2. Applicant's amendment, filed Jun 20, 2017 has been entered and carefully considered.
`
`3. Claims 1, 5, 9 and 10 are amended. Claims 19—20 are added. Claims 1—11, 13—16 and 18—21
`
`are currently pending.
`
`Claim Rejections - 35 USC § 103
`
`4.
`
`The following is a quotation of 35 USC. 103(a) which forms the basis for all
`
`obviousness rejections set forth in this Office action:
`
`(a) A patent may not be obtained though the invention is not identically disclosed or described as set forth in section
`102 of this title, if the differences between the subject matter sought to be patented and the prior art are such that the
`subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary
`skill in the art to which said subject matter pertains. Patentability shall not be negatived by the manner in which the
`invention was made.
`
`5.
`
`Claims 1, 4—5, 9—11, 13—16 and 18—21 are rejected under 35 USC. 103 (a) as being
`
`unpatentable over Obuchi et al. (US 2009/0170443 Al) in view of Vajapeyam (US
`
`2011/0222491 A1) in view of Lee at al. (US 2011/0194478 A1) and further in view of Bala et al.
`
`(US 2010/0098012 A1).
`
`Regarding claim 1, Obuchi discloses a transmitting apparatus (See Abstract, Fig. 3)
`
`comprising:
`
`a transmission mode setting section (Fig. 3; 13) that sets a transmission mode among a plurality
`
`of transmission modes in which a plurality of Downlink Control Inflammation (“DEE”) formats
`
`are associated with a plurality of transmission schemes used for data signals (See Abstract, Par.

`
`Art Unit: 2479
`
`[13], [14], [26], [43], [52] and Fig. 3 of Obuchi for a reference to a radio communication
`
`apparatus is capable of switching from a first mode for transmitting data by selecting from
`
`among any of a plurality of transmission formats belonging to a first group to a second
`
`mode for transmitting data by selecting from among any of a plurality of transmission
`
`formats belonging to a second group. For example, in a radio communication system that
`
`includes a first radio communication apparatus selecting any of a plurality of transmission
`
`formats and then transmits data according to the selected transmission format, and a
`
`second radio communication apparatus that receives the data transmitted from the first
`
`radio communication apparatus, the first radio communication apparatus transmits a
`
`control signal for notifying a change of a trend of the transmission format to be applied,
`
`and the second radio communication apparatus switches the candidates of reception
`
`format for trying to perform the receiving process based on the control signal); and
`
`a transmitting section (Fig. 3; 15) that that transmits transniissimi na'x'ie ii’iffiiffiufiiim relating t0
`
`the transmission mode, and transmits the control signals for the one receiving apparatus by
`
`mapping the control signals for the one receiving apparanls to the centrei signal resource (See
`
`[84], [90] and Fig. 3 of Obuchi for a reference to the radio frame generator 14 multiplies
`
`the transmission data (the data transmitted through a Physical Downlink Shared Channel
`
`(PDSCH)) given from the data generator 12 with the control information (the data
`
`transmitted through a Physical Downlink Control Channel (PDCCH)) from the control
`
`information generator 13 to form a radio frame, and then makes a radio transmitter 15
`
`transmit the data as a radio signal through the antenna. When the control information is
`
`transmitted through the control channel, the control information includes, for example, ID
`
`

`

`
`Art Unit: 2479
`
`information of the mobile station 2. This allows the mobile station 2 to determine whether
`
`or not there is control information addressed to itself in the area surrounded by the dotted
`
`line B. Furthermore, it is possible to notify the mobile station of which region (resource)
`
`and which demodulation method are used to transmit the data by the transmission format
`
`included in the control information),
`
`Obuchi does not explicitly disclose that a first transmission mode for a Relay-Physical Downlink
`
`Control Channel (“RPDCCH”) region anti a, second, transmission mode for a Physical Downiink
`
`Control Channei (“PDCCi-t”) region are. being set by the transmission mode setting section.
`
`i-iowever, Vajapeyam discloses this (See Par. {52} _ [57 i of Vajapeyam for a reference to a
`
`first mapping scheme, each PDCCH location may be mapped to at most one R-PDCCH
`
`location. For example, PDCCH region i may be mapped to R-PDCCH region i, for i=1, .
`
`.
`
`. ,
`
`P, where P may be the smaller of K and M. Control information for a given UE may be
`
`sent at PDCCH location i in the control region and also at R-PDCCH location i in the data
`
`region. For this mapping scheme, the UE may perform blind decoding for only P possible
`
`combinations of the PDCCH and R-PDCCH that can be used to send control information
`
`to the UE. In a second mapping scheme, each PDCCH location may be mapped to L R-
`
`PDCCH locations, where L may be smaller than M. For example, PDCCH location k may
`
`be mapped to R-PDCCH locations (k mod M) through ((k+L-1) mod M), where "mod"
`
`denotes a modulo operation. Control information for a given UE may be sent at PDCCH
`
`location k in the control region and also at one of L possible R-PDCCH locations in the
`
`data region. For the second mapping scheme, the UE may perform blind decoding for
`
`

`
`Art Unit: 2479
`
`K.times.L possible combinations of the PDCCH and R-PDCCH that can be used to send
`
`control information to the UE)
`
`the first transmission nintie is different from the second transmission mode (See Par. [33], [52]-
`
`[53] of Vajapeyam for a reference to the PDCCH and R-PDCCH are separate control
`
`channels that can be independently configured and operated. Furthermore, control
`
`information is conventionally sent on only the PDCCH or only the R-PDCCH. UEs may be
`
`configured in various manners to monitor only the PDCCH, or only the R-PDCCH, or both
`
`the PDCCH and R-PDCCH for control information. In one design, a UE may be eXplicitly
`
`or implicitly configured to monitor the PD CCH. The UE may also be configured to monitor
`
`the R-PDCCH, e.g., via separate signaling. The UE may also be configured to monitor both
`
`the PDCCH and R-PDCCH, which may be referred to as a joint assignment of the PDCCH
`
`and R-PDCCH. Each designated UE may perform blind decoding for a set of combinations
`
`of the PDCCH and R-PDCCH to monitor for control information when the control bit is
`
`set to the first value. The control bit may be set to a second value (e.g., ‘0‘) to indicate that
`
`the designated UEs should monitor only the PDCCH and/or only the R-PDCCH (i.e., only
`
`the PDCCH, or only the R-PDCCH, or the PDCCH and R-PDCCH separately))
`
`a transmission scheme determining section that determines a transmission scheme for data
`
`signals for fine receiving apparatus and determines a centre} signal resource used to transmit
`
`control signals fer the nne receiving apparatus based en the determined transrnissien 86116136., the
`
`first transmission innde and the second transniissinn mode (See Fig. 11; 1112, Par. [53]-[57] of
`
`Vajapeyam for a reference to the K PDCCH locations may be mapped to the M R-PDCCH
`
`locations based on a predetermined mapping in order to reduce the number of possible

`

`Application/Control Number: 13/984,152
`
`Page 6
`
`Art Unit: 2479
`
`combinations of the PDCCH and R-PDCCH for blind decoding. In a first mapping scheme,
`
`each PDCCH location may be mapped to at most one R-PDCCH location. For example,
`
`PDCCH region i may be mapped to R-PDCCH region i, for i=1, .
`
`.
`
`. , P, where P may be the
`
`smaller of K and M. Control information for a given UE may be sent at PDCCH location i
`
`in the control region and also at R-PDCCH location i in the data region. For this mapping
`
`scheme, the UE may perform blind decoding for only P possible combinations of the
`
`PDCCH and R-PDCCH that can be used to send control information to the UE. In a
`
`second mapping scheme, each PDCCH location may be mapped to L R-PDCCH locations,
`
`where L may be smaller than M. For example, PD CCH location k may be mapped to R-
`
`PDCCH locations (k mod M) through ((k+L-1) mod M), where "mod" denotes a modulo
`
`operation. Control information for a given UE may be sent at PDCCH location k in the
`
`control region and also at one of L possible R-PDCCH locations in the data region. For the
`
`second mapping scheme, the UE may perform blind decoding for K.times.L possible
`
`combinations of the PDCCH and R-PDCCH that can be used to send control information
`
`to the UE)
`
`Thus it would be obvious for one of ordinary skills in the art at the time of the invention to
`
`combine the teachings of Vajapeyam and Obuchi. The motivation of combination is to improve
`
`reliability by enabeling control information to be sent on multiple control channels, which may
`
`be independently configured and operated. (Vajapeyam; Par. [07]).
`
`The combination of Obuchi and Vajapeyam does not explicitly disclose w hen the. determined
`
`transmission scheme is asseeiated with a first DCE format in the first transmission made, the
`
`transmission scheme. determining section tieteiinines the control signal resource in the R—

`

`
`format to the control signals. ii-iowever, Lee discloses this (See Par. [SH-[53] and Fig. 6-8 of
`
`Lee for a reference to the control information being transmitted through the PDCCH is
`
`referred to as Downlink Control Information ( DCI), which may include uplink resource
`
`allocation information, downlink resource allocation information, and uplink transmission
`
`power control commands on random UE groups. The PDCCH may carry and deliver
`
`transmission format information and resource allocation information of a downlink shared
`
`channel (DL-SCH), paging information within a paging channel (PCH), system
`
`information within the DL-SCH, resource allocation information on higher layer control
`
`messages, such as random access responses being transmitted within the PDSCH,
`
`transmission power control command sets on individual UEs within random UE groups,
`
`information on transmission power control commands, information on the activation of a
`
`Voice of Internet Protocol (VoIP), and so on. The eNB decides the PDCCH format
`
`depending upon the DCI that is to be transmitted to the UE and adds a CRC to the control
`
`information. The CRC is masked with a unique identifier (i.e., Radio Network Temporary
`
`Identifier (RNTI)) in accordance with the purpose or owner of the PDCCH. Additionally,
`
`in order to appropriately receive the information that is being delivered through the
`
`PDSCH, control information is delivered to the UE through the Physical Downlink Control
`
`Channel (PDCCH). More specifically, the information through the PDCCH may include
`
`

`

`Application/Control Number: 13/984,152
`
`Page 8
`
`Art Unit: 2479
`
`information on the UE that is to receive through the PDSCH, the frequency and time
`
`information of the radio resource Within the PDSCH, the transmission format of the
`
`PDSCH, and so on. If the UE successfully receives the PDCCH, the UE may adequately
`
`receive the random access response being transmitted through the PDSCH based upon the
`
`control information through the PDCCH)
`
`Thus it would be obvious for one of ordinary skills in the art at the time of the invention to
`
`combine the teachings of Lee, Vajapeyam and Obuchi. The motivation of combination is to
`
`efficiently perform random access of a Wireless device limited to a Wireless (or radio) interface.
`
`(Lee; Par. [20]).
`
`The combination of Obuchi, Vajapeyam and Lee does not explicitly disclose the transmission

`comes :‘ondence anions a transmission mode. DCE format and transmission scheme for the
`
`
`
`
`
`
`PDCCH region and the R--PDCCH region. However, Bela discloses this {See Par. [112]-[113]
`
`and Table 4 of Bala for a reference to some parameters, e.g., reporting mode, periodicity,
`
`etc. are sent via RRC signaling, and the other parameters e.g., resources, RB location,
`
`MCS, etc. are indicated via L1 control signaling e.g., PDCCH. Some parameters, e.g.,
`
`reporting mode, periodicity, etc. are sent via RRC signaling, and the other parameters e.g.,
`
`resources, RB location, MCS, etc. are indicated via L1 control signaling e.g., PDCCH. In
`
`addition some code-points are defined for PDCCH validation. Validation is achieved if all
`
`the fields for the respective used downlink control indicator ( DCI) format are set
`
`according to, for example, as shown in Table 4. If validation is achieved, the WTRU may
`
`

`

`
`Page 9
`
`Art Unit: 2479
`
`consider the received DCI information accordingly as a valid periodic PUSCH
`
`activation) .
`
`Thus it would be obvious for one of ordinary skills in the art at the time of the invention to
`
`combine the teachings of Kim, Lee, Vajapeyam and Obuchi. The motivation of combination is
`
`providing flexible configuration in signaling UCI, efficient resource utilization, and support for
`
`high volume UCI overhead in LTE—A. (Bala; Par. [88]).
`
`Regarding claim 4, Obuchi discloses the transmitting apparatus of claim 1;
`
`wherein the transmission mode information is transmitted through one kind of signaling (See
`
`Par. [25]-[26] of Obuchi for a reference to the transmission formats belonging to the first
`
`group have the same transmission intervals. According to an aspect of the invention, a
`
`radio communication apparatus which receives data from another radio communication
`
`apparatus capable of switching from a first mode for transmitting data by selecting from
`
`among any of transmission formats belonging to a first group to a second mode for
`
`transmitting data by selecting from among any of transmission formats belonging to a
`
`second group. The radio communication apparatus includes a receiving processor that
`
`receives notification when mode switching is conducted from the first mode to the second
`
`mode, and switches a plurality of reception formats for making a trial receiving process
`
`according to the reception of the notification from among reception formats corresponding
`
`to the transmission formats belonging to the first group to reception formats corresponding
`
`to the transmission formats belonging to the second group).

`

`

`
`Page 10
`
`Art Unit: 2479
`
`Regarding claim 5, Obuchi discloses a receiving apparatus (See Abstract and Fig. 5)
`
`comprising:
`
`a receiving section (Fig. 5; 20) that receives control signals addressed to the receiving apparatus
`
`transmitted from a transmitting apparatus (See Abstract, Par. [13], [42], [66], [93]-[94] of
`
`Obuchi for a reference to the second radio communication apparatus includes a receiving
`
`processor that switches a candidate of receiving formats used for finding a receiving format
`
`to obtain a normal reception result based on the control signal. The second radio
`
`communication apparatus that receives the data transmitted from the first radio
`
`communication apparatus, the first radio communication apparatus transmits a control
`
`signal for notifying a change of a trend of the transmission format to be applied, and the
`
`second radio communication apparatus switches the candidates of reception format for
`
`trying to perform the receiving process based on the control signal. By receiving the
`
`certain signal (control signal), it is assumed that the mode is changed, and the mobile
`
`station performs the blind detection by switching from the first set to the second set)
`
`a control signal detection section (Fig. 5; 24) that searches the control signals in the first
`
`resource region and the second resource region and detects a detection region in which the
`
`control signals are detected out of the first resource region and the second resource region and a
`
`control signal format applied to the detected control signals (See Abstract, Par. [79], [96], [97],
`
`[99], [101], [124], [129] of Obuchi for a reference to the error detector 24 estimates which
`
`format is correct of the applied reception formats by using an error detection bit (for
`
`

`

`Application/Control Number: 13/984,152
`
`Page 11
`
`Art Unit: 2479
`
`example, a CRC bit) or the like added to the data. It is assumed that the reception format
`
`Without errors is a correct reception format, and then the error detector 24 gives the
`
`corresponding receiving process result to the data processing device. In general, if the
`
`receiving process is performed by an incorrect reception format, it is considered that there
`
`is a low possibility that the reception result is correct. Then the error detector 24 performs
`
`error detection processing or the like for the result of each receiving process. If no error is
`
`detected, an ACK is given to the radio frame generator 26 and is transmitted (step 6), and
`
`the data in which no error is detected is given to the data processing device and is
`
`reproduced. If an error is detected on all the trials of the reception formats, a NACK is
`
`given to the radio frame generator 26 and is transmitted); and
`
`a transmission scheme specification section (Fig. 5; 22) that specifies a transmission scheme
`
`usetl for data signals transmitted. front the transmitting apparatus, based on (i) a txii'respondence
`
`rule that associates a plurality til" tran snrission mode candidates with a plurality til" DCl formats
`
`corresponding to the respective. transmission mode candidates and transmission
`
`schemes corresponding to the respective control signal formats, (ii) the first transmission mode
`
`anti the second transmission mode indicated by the transmission motle information , and (iii) the
`
`detection region anti the detected DCi format that were detected by the coi'itroi signal detection
`
`section (See Abstract, Par. [16], [17], [20], [42], [62], [65], [95] and fig. 2 of Obuchi for a
`
`reference to the control signal includes information for specifying any of the transmission
`
`formats belonging to the second group. Preferably, the control signal includes the
`
`information for specifying any of the transmission formats belonging to the second group
`
`and any of the transmission formats belonging to the first group. the first radio
`
`

`

`Application/Control Number: 13/984,152
`
`Page 12
`
`Art Unit: 2479
`
`communication apparatus transmits a control signal for notifying a change of a trend of the
`
`transmission format to be applied, and the second radio communication apparatus
`
`switches the candidates of reception format for trying to perform the receiving process
`
`based on the control signal. In the example of FIG. 2, since it is notified that the
`
`transmission format is T2A by the certain signal (control signal), the mobile station may
`
`perform correct receiving process by performing the receiving process using the reception
`
`format R2A corresponding to the notified transmission format T2A. That is, the receive
`
`processing does not have to be performed using the other candidate R2B. At this time, the
`
`base station transmits the data by using the transmission format T2A. For example, if the
`
`information for specifying the first set and the second set is included in the control
`
`information or the information for specifying the transmission format itself is included in
`
`the control information, the information is given to the data receiver 23),
`
`a transmission mode set by the transmitting apparatus, the transmission mode being set for each
`
`of the first resource region and the second resource region, and the detection region and the
`
`control signal format detected by the control signal detection section (See Abstract, Par. [13],

`
`reference to the error detector 24 estimates which format is correct of the applied reception
`
`formats by using an error detection bit (for example, a CRC bit) or the like added to the
`
`data. It is assumed that the reception format Without errors is a correct reception format,
`
`and then the error detector 24 gives the corresponding receiving process result to the data
`
`processing device. In general, if the receiving process is performed by an incorrect
`
`reception format, it is considered that there is a low possibility that the reception result is

`
`correct. Then the error detector 24 performs error detection processing or the like for the
`
`result of each receiving process. If no error is detected, an ACK is given to the radio frame
`
`generator 26 and is transmitted (step 6), and the data in which no error is detected is given
`
`to the data processing device and is reproduced. If an error is detected on all the trials of
`
`the reception formats, a NA CK is given to the radio frame generator 26 and is transmitted.
`
`a radio communication apparatus is capable of switching from a first mode for
`
`transmitting data by selecting from among any of a plurality of transmission formats
`
`belonging to a first group to a second mode for transmitting data by selecting from among
`
`any of a plurality of transmission formats belonging to a second group. For example, in a
`
`radio communication system that includes a first radio communication apparatus selecting
`
`any of a plurality of transmission formats and then transmits data according to the selected
`
`transmission format, and a second radio communication apparatus that receives the data
`
`transmitted from the first radio communication apparatus, the first radio communication
`
`apparatus transmits a control signal for notifying a change of a trend of the transmission
`
`format to be applied, and the second radio communication apparatus switches the
`
`candidates of reception format for trying to perform the receiving process based on the
`
`control signal).
`
`Obuchi does not explicitly disclose that a first transmission mode for a Remy-Physical Downiink
`
`Control Channel (“R—PDCCH”) region and a second transmission mode for a Physical Downtink
`
`Con/{mi Channel {“PDCCE-l”) region are being set by the transmission, mods: setting section.
`
`However. Vajapeyani discloses this (See Par. 3252:} —~ {5?} of Vajapeyam for a reference to a

`
`combinations of the PDCCH and R-PDCCH that can be used to send control information
`
`to the UE. In a second mapping scheme, each PDCCH location may be mapped to L R-
`
`PDCCH locations, where L may be smaller than M. For example, PDCCH location k may
`
`be mapped to R-PDCCH locations (k mod M) through ((k+L-1) mod M), where "mod"
`
`denotes a modulo operation. Control information for a given UE may be sent at PDCCH

`
`channels that can be independently configured and operated. Furthermore, control
`
`information is conventionally sent on only the PDCCH or only the R-PDCCH. UEs may be
`
`configured in various manners to monitor only the PDCCH, or only the R-PDCCH, or both
`
`the PDCCH and R-PDCCH for control information. In one design, a UE may be eXplicitly
`
`or implicitly configured to monitor the PD CCH. The UE may also be configured to monitor
`
`the R-PDCCH, e.g., via separate signaling. The UE may also be configured to monitor both
`
`the PDCCH and R-PDCCH, which may be referred to as a joint assignment of the PDCCH

`
`of the PDCCH and R-PDCCH to monitor for control information when the control bit is
`
`set to the first value. The control bit may be set to a second value (e.g., ‘0‘) to indicate that
`
`the designated UEs should monitor only the PDCCH and/or only the R-PDCCH (i.e., only
`
`the PDCCH, or only the R-PDCCH, or the PDCCH and R-PDCCH separately))

`
`Thus it would be obvious for one of ordinary skills in the art at the time of the invention to
`
`combine the teachings of Vajapeyam and Obuchi. The motivation of combination is to improve
`
`reliability by enabeling control information to be sent on multiple control channels, which may
`
`be independently configured and operated. (Vajapeyam; Par. [07]).
`
`The combination of Obuchi and Vajapeyam does not explicitly disclose when the determined
`
`transmission scheme is nssoeiateti with a first DCl format in the. first transmission mode, the.
