`
`Claims 1,

`
`Jin teaches a mobile terminal (Jin fig 12 UE) and method for performing a
`
`handover procedure in a mobile communication system from a source base
`
`station (Jin fig 12 source gNB) to a target base station (Jin fig 12 target gNB),
`
`the target base station being configured for the mobile terminal with at least a
`
`first bandwidth part within its cell bandwidth part (Jin par 0173 a first active
`
`BWP configured by the target gNB for the UE), the mobile terminal
`
`comprising: a transceiver (Jin fig 27 par 0337 RF processor) which, in
`
`operation, receives from the source base station a handover command message
`
`(Jin fig 12 step 2g-25 par 0173 UE receives handover command from
`
`source gNB) including information regarding the configured atleastfirst
`
`bandwidth part (Jin par 0173 the handover commandincludesthefirst active
`
`BWP configured by the target gNB for the UE); and a processor (Jin fig 27
`
`

`

`Application/Control Number: 16/991 ,391
`Art Unit: 2647
`
`Page 4
`
`par 0341 controller) which, in operation and upon reception of the handover
`
`command message (Jin fig 12 step 2g-25 par 0173 receives handover
`
`command), activates in the transceiver at least a pre-selected one of the
`
`configured at leastfirst bandwidth part (Jin fig 12 step 2g-45 par 0174 UE
`
`communicates random access messagesusing thefirst active BWP
`
`configured by the target gNB for the UE. The BWP configured bythe target
`
`QNB for the UE are the pre-selected one of the configured BWP. To
`
`communicate random access messagesusing the first active BWP, the UE
`
`mustactivate the first active BWP), and controls the transceiver to perform,
`
`over the activated at least one of the configured at leastfirst bandwidth part,
`
`communication with the target base station as part of the handover procedure
`
`(Jin fig 12 step 2g-45 par 0174 communicates random access messages
`
`with the target gNB over the active BWP aspart of handover).
`
`Jin teachesthe target gNB configures a first BWP for the UE. Jin does not
`
`specifically teach the target gNB configuresafirst bandwidth part and a second
`
`bandwidth part for the UE. Futaki discloses the target gNB configures a first
`
`bandwidth part and a second bandwidth part (Futaki par 0112-0113 the source
`
`QNB indicatesto the target gNB at least one configured BWP for the UE at
`
`the source gNB {second bandwidth part}, at least one activated BWP for
`
`the UE at the source gNB {first bandwidth part}, and “at least one candidate
`
`BWPto whichthe UEis to be handed over’. The target gNB, in turns,
`
`configures at least one BWP for the UE corresponding to the indicated “at
`
`least one candidate BWPto whichthe UEis to be handed over’. The at
`
`

`

`Application/Control Number: 16/991 ,391
`Art Unit: 2647
`
`Page 5
`
`least one BWP configured by the target gNB for the UE includes two or
`
`more BWPs, thereby teaching the target gNB configuresa first bandwidth
`
`part and a second bandwidth part for the UE). Before the effective filing date
`
`of the claimed invention, it would have been obvious for one ordinarily skilled in
`
`the art to modify the invention of Jin with Futaki by adding to source gNB the
`
`method of providing to the target gNB indication of two or more candidate BWPs
`
`to which the UE is to be handed over and adding to the target gNB the method of
`
`configuring for the UE two or more BWPs comprises a first bandwidth part and a
`
`second bandwidth part corresponding to the two or more candidate BWPs where
`
`the first bandwidth part is replacedbythe first active BWAP of Jin. The
`
`motivation to combine Jin and Futaki is to configure a same number of BWPsfor
`
`a UE at the target gNB as that configured for the UE at the source gNB to
`
`prevent service disruption due to insufficient bandwidth parts at the target gNB.
`
`
`Claims 4, 12
`
`Jin teachesa target base station (Jin fig 12 target gNB) and methodfor
`
`performing a handover procedure of a mobile terminal in a mobile communication
`
`system from a source basestation (Jin fig 12 source gNB), the target base
`
`station being capable of communicating with the mobile terminal (Jin fig 12 UE)
`
`over eachofat least a first bandwidth part within its cell bandwidth (Jin par 0173
`
`a first active BWP configured by the target gNB for the UE), the target base
`
`station comprising: a transceiver (Jin fig 28 par 0344 RF processor) which, in
`
`operation, receives from the source base station a handover request message
`
`(Jin fig 12 step 2g-15 par 0172 target gNB receives a handover request
`
`

`

`Application/Control Number: 16/991 ,391
`Art Unit: 2647
`
`Page 6
`
`message from source gNB); and a processor (Jin fig 28 par 0348 controller)
`
`which, in operation and upon reception of the handover request message (Jin fig
`
`12 step 2g-15 par 0172 handover request message), controls the transceiver
`
`to configure for the mobile terminal at least the first bandwidth part (Jin par 0173
`
`target gNB configures the first active BWP for the UE), and controls the
`
`transceiver to transmits to the source base station a handover request
`
`acknowledge message (Jin fig 12 step 2g-20 par 0173 transmits the
`
`handover request ACK to the source gNB), wherein the handover request
`
`acknowledge message includesinformation regarding the configured atleastfirst
`
`bandwidth part (Jin fig 12 step 2g-20 par 0173 the handover request ACK
`
`includesthe first active BWP for the UE {first bandwidth part} for delivery
`
`to the UE via the handover command[fig 12 step 2g-25)).
`
`Jin teachesthe target gNB configuresafirst BWP for the UE and
`
`handover request and handover request ACK messages. However, Jin does not
`
`specifically teach the target gNB configuresafirst bandwidth part and a second
`
`bandwidth part for the UE, the handover request message including information
`
`regarding the capability of the mobile terminal to communicate over at least the
`
`first bandwidth part and second bandwidth part, the handover request
`
`acknowledge message includesinformation regarding the configured atleastfirst
`
`bandwidth part and second bandwidth part. Futaki discloses the target gNB
`
`configures a first bandwidth part and a second bandwidth part (Futaki par 0112-
`
`0113 the source gNB indicates to the target gNB “at least one candidate
`
`BWPto whichthe UEis to be handed over’. The target gNB,in turns,
`
`

`

`Application/Control Number: 16/991 ,391
`Art Unit: 2647
`
`Page 7
`
`configures at least one BWP for the UE corresponding to the indicated “at
`
`least one candidate BWPto whichthe UEis to be handed over’. The at
`
`least one BWP configured by the target gNB for the UE includes two or
`
`more BWPs, thereby teaching the target gNB configuresa first bandwidth
`
`part and a second bandwidth part for the UE), the handover request message
`
`(Futaki fig 15 step 1501 par 0112 source gNB transmits to the target gNB a
`
`handover request message)including information regarding the capability of
`
`the mobile terminal to communicate over at least the first bandwidth part and
`
`second bandwidth part (Futaki fig 15 step 1501 par 0112 the message
`
`comprises at least one activated BWP for the UE at the source gNB {a first
`
`bandwidth part} and at least one configured BWP for the UE at the source
`
`{a second bandwidth part}; the BWPsfor the UE enables the UE to
`
`communicate with the source gNB, teaching the capability of the UE to
`
`communicate overatleast first bandwidth part and second bandwidth part)
`
`and the handover request acknowledge message (Futaki fig 15 step 1502 par
`
`0113 target gNB transmits to source gNB a handover request ACK
`
`message)includes information regarding the configured at leastfirst bandwidth
`
`part and second bandwidth part (Futaki par 0112-0113 the target gNB
`
`configures at least one BWP for the UE corresponding to the “at least one
`
`candidate BWPto which the UEis to be handedover’indicated by the
`
`source gNB. The target gNB includesin the handover request ACK
`
`message the at least one BWP configured by the target gNB for the UE. The
`
`at least one BWP configured by the target gNB for the UE includes two or
`
`

`

`Application/Control Number: 16/991 ,391
`Art Unit: 2647
`
`Page 8
`
`more BWPs, thereby teaching a first bandwidth part and a second
`
`bandwidth part ). Before the effective filing date of the claimed invention, it
`
`would have been obvious for one ordinarily skilled in the art to modify the
`
`invention of Jin with Futaki by adding to source gNB the methodofincluding in
`
`the handover request message the active BWPsfor the UE at the source gNB,
`
`the configured BWPsfor the UE at the source gNB, and two or more candidate
`
`BWPsto which the UE is to be handed over, adding to the target gNB the
`
`method of configuring for the UE two or more BWPscomprisingafirst bandwidth
`
`part and a second bandwidth part corresponding to the two or more candidate
`
`BWPs, and adding to the target gNB the methodof including in the handover
`
`request ACK message the two or more BWPsconfigured by the target gBN for
`
`the UE comprising the first bandwidth part and the second bandwidth part where
`
`the first bandwidth part is replacedbythe first active BWAP of Jin. The
`
`motivation to combine Jin and Futaki is to use the configuration at the source
`
`gNB to configure a same number of BWPsfor a UE at the target gNB asthat
`
`configured for the UE at the source gNB to prevent service disruption in a
`
`handover due to insufficient bandwidth parts at the target gNB.
`
`Claim 3
`
`Jin in view of Futaki teaches the mobile terminal according to claim 1,
`
`wherein the processor controls the transceiver to perform at least a random
`
`access message transmission to the target base station as part of the handover
`
`procedure (Jin fig 2 step 2g-45 par 0174 UE performs random access
`
`procedure with the target gNB); and in case the received handover command

`Application/Control Number: 16/991 ,391
`Art Unit: 2647
`
`Page 9
`
`message (Jin fig 2 step 2g-25 handover command) additionally includes a
`
`plurality of different random access transmission parameters associated (Jin fig
`
`2 step 2g-25 par 0173-0174 handover commandincludesthe first active
`
`BWP for the UE to use to perform the random accessprocedure[fig 2 step
`
`2g-45], the BWP configuration includes the frequency and subframe to use,
`
`etc ... {different random access transmission parameters}) with at least the
`
`pre-selected one of the configured at least first bandwidth part and second
`
`bandwidth part (Jin par 0173 first active BWP configured for the UE by the
`
`target cell is the pre-selected one of the configured at least bandwidth part
`
`and second bandwidth part); the processor controls the transceiver to perform
`
`at least a random access message transmission to the target base station using
`
`the random access transmission parameters associated to the activated pre-
`
`selected one of the configured at least first bandwidth part or the second
`
`bandwidth part (Jin fig 2 3g-45 par 0174 UE usesthe first active BWP
`
`configured for the UE by the target node {activated pre-selected one of the
`
`configuredatleast first bandwidth part} o transmit the preamble ID to the
`
`target gNB in random accessprocedure).
`
`Claim 6
`
`Jin in view of Futaki teaches the target base station according to claim 4,
`
`wherein: the handover request message additionally includes information
`
`regarding the state of the activated bandwidth part (Jin in view of Futaki
`
`teaches a handover request message comprises BWP information of at
`
`least one BWP for the UE at the source gNB. Futaki par 0102 BWP

`Art Unit: 2647
`
`Page 10
`
`information includes availability of network slicing in the BWP {state of
`
`activated bandwidth part}. |t would be obvious for a person skilled in the
`
`art to add state of the BWP in the BWP information included in the
`
`handover request message. The motivation to combineis to convey the
`
`state of the active BWP for the target gNB to configure a BWP for the UE
`
`with the same state in a handover) or predictedtraffic information; and the
`
`processor, in operation and upon reception of the handover request message
`
`(Jin fig 12 step 2g-15 par 0173 target gNB receives handover request),
`
`controls the transceiver to select and activate at least one the at leastthe first
`
`bandwidth part and the second bandwidth part (Jin in view of Futaki teaches
`
`configuring {select} and transmitting the two BWPsfor the UE, i.e. at least
`
`the first bandwidth part and the second bandwidth part, in the handover
`
`request ACK message.Jin fig 12 step 2g-45 par 0174 the UE uses the
`
`BWPsconfigured for the UE to exchange random access messages with
`
`the target gNB; to be able to exchange the messages, the target gNB must
`
`activate the BWPs)which the mobile terminal, as part of the handover
`
`procedure, is expected to activate as the pre-selected bandwidth part (Jin fig 12
`
`step 2g-45 par 0174 the UE expected to use {activate} the BWP configured
`
`for the UE by the target gNB to perform random accessprocedure with the
`
`target gNB aspart of the handover. The BWP configured for the UE by the
`
`target gNB is the pre-selected bandwidth part).

`
`Claims 2,5, 10 are rejected under 35 U.S.C. 103 as being unpatentable over Jin
`
`et al (US 2019/0149421 A1) in view of Futaki et al (US 2019/0182716 A1) as applied
`
`to claims 1, 4 above further in view of CATT 2 (CATT, BWP Model, 3GPP TSG-RAN
`
`WG2 Meeting #99bis R2-1710275, Prague Czech Republic, 9-13 Oct 2017).
`
`Claim2
`
`Jin in view of Futaki teaches the mobile terminal according to claim 1,
`
`wherein the information (Jin par 0176 a message includesindicator
`
`indicating the active BWP) regarding the configured at least first bandwidth part
`
`(Jin in view of Futaki teachesfirst active BWP) and second bandwidth part
`
`(Jin in view of Futaki teaches second BWP) hasa specific sequence (Jin par
`
`0176 active BWP maybereconfigured from the current active BWP to
`
`another BWP or the default BWP when the current active BWP is no longer
`
`active; thereby teaching the specific sequence current active BWP {first
`
`bandwidth part} followed by the default BWP {second bandwidth part}), and
`
`the processor, in operation, activates, as the pre-selected one of the bandwidth
`
`parts (Jin fig 12 2g-45 par 0174 UE transmit {activate} random access
`
`messages using UL BWP ofthefirst active BWP), the first (Jin par 0176 the
`
`

`

`Page 17
`
`first active BWP if the active indicator indicating the first active BWP)or last
`
`or a specific other one, if more than the at leastfirst bandwidth part and the
`
`second bandwidth part are configured (Jin par 0176 BWPsinclude thefirst
`
`active BWP {first bandwidth part}, the another BWP, the default BWP
`
`{second bandwidth part}), in the specific sequence (Jin par 0176 the
`
`sequenceis the first bandwidth part followed by the second bandwidth
`
`part); and the received message additionally includes a bandwidth part index
`
`(Jin par 0171 message includes index of the BWP toactivate), and the
`
`processor activates the pre-selected one of the configured atleastfirst bandwidth
`
`part (Jin 0171 activates the first active BWP if the index in the message
`
`indicatesthe first active BWP) or the second bandwidth part which
`
`correspondsto the bandwidth part index (Jin par 0171 each index corresponds
`
`to a BWP).
`
`Jin in view of Futaki teaches including in handover messages the BWPs
`
`configured for the UE at the target gNB. However Jin in view of Futaki does not
`
`specifically teach the handover command message additionally includes a
`
`bandwidth part index. CATT 2 discloses the handover command additionally
`
`includes a bandwidth part index (CATT 2 proposals 2-4 BWP_index and
`
`should be indicated in a handover command). Before the effectivefiling date
`
`of the claimed invention, it would have been obvious for one ordinarily skilled in
`
`the art to modify the invention of Jin in view of Futaki with CATT 2 by adding the
`
`method of including in the handover command messages of Jin in view of Futaki
`
`the BWP index identifying the specific BWP configured by the target gNB for the
`
`

`

`Application/Control Number: 16/991 ,391

`
`Page 18
`
`UE. The motivation to combine Jin in view of Futaki and CATT2 is to reduce the
`
`handover message size by including in the message only the specific BWP index
`
`identifying the corresponding BWP configuration in lieu of the BWP configuration.
`
`Claim 5
`
`Jin in view of Futaki teaches the target base station according to claim 4,
`
`wherein the processor, in operation and after controlling the transmitter to
`
`transmit the handover request acknowledge message (Jin fig 12 step 2g-20 par
`
`0173 transmits handover request ACK message), activates in the transmitter
`
`the same pre-selected one of the configured atleastfirst bandwidth part (Jin par
`
`0173-0174 target gNB configuresthe first BWP for the UE and makeactive
`
`{activates} the first BWP asthe first active BWP to exchange messages
`
`with the UE) or second bandwidth part which the mobile terminal is expected to
`
`activate (Jin par 0173-0174 UE usesthe receivedfirst active BWP to
`
`transmit {activate} random access messages); the information regarding the
`
`configured at leastfirst bandwidth part and second bandwidth part (Jin in view
`
`of Futaki teachesa first active BWP {first bandwidth part} and a second
`
`BWP {second bandwidth}) has a specific sequence (Futaki par 0078 the
`
`active BWP switchesto the default BWP or another BWP when the first
`
`active BWP no longertransmits or
