`
`Claim 14, Hwang discloses 4 communication apparatus, comprising:
`
`@ receiver which, in operation, receives a Wake-up Radio (WUR) Beacon
`
`transmission ([0031] the low-power STA located within the coverage of the access point
`
`can receive the WLU beacon frame from the access point); and
`
`circuitry which (fig 8, [0078] 4 low-power STA 500 may inclucle a baseband
`
`processor 510, a primary connectivily racic (PCR) 520, an antenna 530, a memory 5406,
`
`an input interface uni 550, an output interface unit 560, a wake-up radio (WUR}) 570,
`
`and the like}, in operation, determines wake-up operating parameters including a
`
`starting poirit of duly cycle schedule af the receiver (00261 The operation parameters
`
`may inclucie at least one af information indicating whether the access pcint supports the
`
`station operating in the WUR mode and information indicating a duration in which the
`
`station operates in a WUR duty-cycle mode},
`
`wherein the duty cycle schedule specifies a period of one WUR duly cycle
`
`inclucling one on duration and one off duration (0022) information indicating an ON/OFF
`
`ratio in the duty-cycle duration of the WU}: and
`
`enters WUR mode by communicating with a secand communication apparatus
`
`GO023) The WUR operating in @ wake-up slate, a WUR beacon frame from an access
`
`point: when the WUR beacon frame is received, transition an operation state of the PCR
`
`from a sleep state to a wake-up state; and periorm, by the PGR operating in the wake-
`
`up stale, communications with the access paint),
`
`bul does not explicitly disclose,
`
`wherein cach timing of the starting point of the duty cycle schedule af the
`
`receiver is aligned with 4 target WUR Beacon transmission time (TWETT) of the WUR

`Art Unit: 2647
`
`Page 4
`
`Beacon transmission in the WUR made or aloned with the TWBTT with an added time
`
`ofiset.
`
`However, as Huang discloses wherein each timing of the starting point of the
`
`duty cycle schedule of the receiver is aligned with a target WUR Beacon transmission
`
`ime (TWBTT) of the WUR Beacon transmission in the WUR mode (FlG 7, [0051] The
`
`period af which the WLAN radio 420 is woken is shawn al 706. As can be appreciated,
`
`the period 706 equals a multiple (¢.g., twice} of the beacon intervals, Le., time belween
`
`two TRTTs, and the WLAN radio 420 is woken at the startafa TETT) or alaned with the
`
`TWETT with an added time offset.
`
`Therefore, osfore the effective fling date of the claimed invention, it would have
`
`been obvious to a person having ordinary skill in the art io modify the Fhvang invention
`
`with Huang invention to include the claimed Hmitation(s) so as fo enable the network to
`
`send beacon frame al the target wake-up radio beacon transmission times coairicidental
`
`with radio wakeup time in orderfor the device to receive the beacons.
`
`Giaim 17, Hwang as modified discloses the communication apparatus according
`
`to claim 14, wherein the wake-up operating parameters includes a period of the duly
`
`cycle schedule of the receiver, and the period of the duty cycle schedule is an integer

`mullinle of a WUR Seacon interval or a fraction of the WUR Beacon interval of the WOR
`
`Beacon transmission (Huang [0039] STAs awaken periodically at a target beacen
`
`transmission time (TRTT) to receive beacons). Therefore, before the elective fling
`
`date of the claimed invention, it would have been obvious to 4 person having ordinary
`
`skillin the art to modily the Hwang invention with Huang invention to include the
`
`

`

`Application/Control Number: 16/757 ,217

`
`transmitted periodically by the AP 405 and received at the LP-WUR 425 of the STA
`
`410}. Therefore, before the effective fling date of the claimed invention, it would have
`
`been obvious to a person having ordinary skill in the art to modify the Mwang invention

`
`beer abvious to a person having ordinary skill in the art io modify the Hwang invention
`
`with Huang invention to include the claimed limitation(s} so as ta enable the network to
`

`
`Claim 15, Hwang as modified discloses the cammunicalion apparatus accarding
`
`to claim 14,
`
`out Hwang and Muang invention is silent on,
`
`wherein the cirouliry, in operation, determines the wake-up operating parameters
`
`via a WUR negotiation procedure, and enters the WUR made via a WUR made eniry
`
`pracedure.,
`
`Fowever, as Min discloses wherein the circullry, in operation, determines the
`
`wake-up operating parameters via a WUR negotiation procedure, and enters the WUR
`
`mode via a WUR mode entry procedure (Q032] The AP transmilter, main radio and
`
`receiver can firsi neqotiaie and agree on parameters for the LP-WUR receiver
`
`operation, such as center frequency, bandwidth, etc., before the main racio enters the
`
`low-power wake-up mode (Le., the main radio is off and LP-WUIR is on}.
`
`Therefore, befare the effective fling date of the claimed invention, i would have
`
`been abvious to a person having ordinary skill in the art io modiy the Hwang and

`
`Claim 16, Hwang as modified discloses the communication apparatus according
`
`to claim 14,
`
`bul Hwang and Huang invention is silerit an,
`
`wherein the circullry, in operation, determines the wake-up operating parameters
`
`and enters the WUR mode via an integrated WUR negotiation and a WUR mode entry
`

`
`However, as Min disclases wherein the circuitry, in operation, determines the
`
`wake-up operating parameters anc enters the WUR mode via an integrated WUR
`
`negotiation and a WUR mode entry procedure (0032] The AP transmitter, main radio
`

`
`operalion, such as center frequency, bancwidih, etc., before the main racio enters the
`
`low-power wake-up mode (Le, the main radio is off and LP-WUR is on).
`
`Therefore, before the effective Ming date of the claimed invention, it would have
`
`been obvious to a person having ordinary skill in the art to modify the Mwang and
`
`Huang irivention with Min invention to include the claimed Iimitation(s} so as to enable

`
`(0723) Stations in diferent groups have diferent duly cycle configuration information
`
`and staggered awake windows, without any overlapping part, and the start point of the

`
`duly cycle schedule of the third commurication apparatus (0123) Stations in different
`
`groups have diferent duly cycle configuration information and staggered awake
