The office action notes that:
While Wu teaches and reads on claim features noted above including target cell selection based upon per ¶0067 i.e. “the UE selects the candidate cell, which meets the corresponding handover condition firstly” which implies application of priority to selection of candidate cells within a timer that suspends or holds back individual handovers to allow adequate evaluation do determine which candidate the corresponding handover condition firstly,
Wu does not appear to explicitly teach or strongly suggest (Note – See italicized portions): the first cell having the higher priority; the second cell having a lower priority than the first cell; based on the suspension condition being met and the first cell having the higher priority than the second cell for handover, suspending the execution of the second handover to the second cell having the lower priority within the allowed time duration; a lower bound of the received power of the serving cell; a lower bound of the received power of the first cell; an upper bound of the received power of the second cell;
and furthermore Wu (i.e. in a single embodiment) does not appear to explicitly teach or strongly suggest(Note – See italicized portions): sending, a random-access preamble for a random access;
To teach portions of claim elements which Wu as referenced does not appear to explicitly teach or strongly suggest, the office action combines teachings from Yang from a similar field of endeavor associated with handovers and hand over conditions and reciting overlapping features, where:
Yang teaches: a conditional handover to a first cell or a second cell, wherein the first cell has a higher priority than the second cell for handover, wherein the conditional handover comprises one of a first handover to the first cell or a second handover to the second cell, a first execution condition for the first handover to the first cell having the higher priority; a second execution condition for the second handover to the second cell having a lower priority than the first cell; ( Yang ¶0037 … the UE starts separate timers for each neighbor cell having a signal strength value above the combined value. When this condition persists for a particular time duration, (referred to as the time to trigger (TTT)), for at least one neighbor cell, the UE sends a measurement report (MR) and triggers intra- or inter-frequency handover for the neighbor cell whose TTT timer expires first; ¶0039 […] the best neighbor cell(s) may not be reported for handover/redirection//cell change order if the time to trigger (TTT) timer for the best neighbor cell(s) has not expired […] Aspects of the present disclosure are directed to delaying or postponing reporting a neighbor cell to a network when a TTT timer expires for a neighbor cell that is not the best cell ; ¶0042…. After a UE has determined a neighbor cell is a non-best neighbor cell, and after the non-best neighbor cell's TTT timer expires, the UE does not immediately report the neighbor cell to a network. Rather, the UE delays sending a measurement report, thereby delaying switching to the non-best neighbor cell via hand-over; ¶0047 … When the TTT timer expires for the best neighbor cell(s), the UE sends a measurement report for the best neighbor cell(s)…when…the delay timer expires(and TTT timers are still running for non-best intra-RAT or inter-RAT neighbor cells), the UE sends a measurement report for a non-best neighbor cell);
Which the office action respectfully contends and notes, discloses, teaches, and reads on subject claim limitations as follows: per ¶0037 i.e. each neighbor cell having a signal strength value above the combined value and triggers intra- or inter-frequency handover for the neighbor cell reads on: a conditional handover where the handover is subject to conditions and rules associated with meeting per ¶0037 i.e. a signal strength value above the combined value and triggers such as TTT timer expiry. Furthermore, per ¶0037 where taught are i.e. separate timers for each neighbor cell, and where taught is i.e. the neighbor cell whose TTT timer expires first such as per ¶0042 for i.e. a non-best neighbor cell, and per ¶0047 for i.e. best neighbor cells reads on: to a first cell or a second cell. Furthermore per ¶0047 which teaches i.e. best neighbor cells reads on: wherein the first cell has a higher priority , in relation to per ¶0042 teaching i.e. a non-best neighbor cell reads on: than the second cell for handover . Furthermore per ¶0037 i.e. the neighbor cell whose TTT timer expires first such as applied individually to per ¶0047 i.e. When the TTT timer expires for the best neighbor cell(s), the UE sends a measurement report for i.e. the best neighbor for hand over reads on: wherein the conditional handover comprises one of a first handover to the first cell. Furthermore per ¶0037 i.e. the neighbor cell whose TTT timer expires first such as applied individually to per ¶0047 i.e. the delay timer expires, (and TTT timers are still running for non-best intra-RAT or inter-RAT neighbor cells), the UE sends a measurement report for a non-best neighbor cell reads on: or a second handover to the second cell. In both case conditions and rules have to be met as taught to effect handover.
and a suspension condition indicating an allowed time duration for suspending execution of the second handover to the second cell having the lower priority after the second execution condition is met for the second handover to the second cell(Yang ¶0037 see above; ¶0042 See above; ¶0039 See above; ¶0047 See above);
Which the office action respectfully contends and notes, discloses, teaches, and reads on subject claim limitations as follows: per ¶0039 i.e. delaying or postponing reporting a neighbor cell to a network when a TTT timer expires for a neighbor cell that is not the best cell and per ¶0042 i.e. After a UE has determined a neighbor cell is a non-best neighbor cell, i.e. and after the non-best neighbor cell's TTT timer expires, the UE does not immediately report the neighbor cell to a network i.e. the delaying or postponing reporting a neighbor cell to a network and not immediately report the neighbor cell to a network as configured for the UE reads on: and a suspension condition indicating an allowed time duration associated with the configured delaying prior to reporting the neighbor cell for handover. Furthermore per ¶0042 After a UE has determined a neighbor cell is a non-best neighbor cell, and after the non-best neighbor cell's TTT timer expires i.e. the UE does not immediately report the neighbor cell to a network i.e. the delay suspends reporting to network for handover execution to a non-best neighbor cell reads on: for suspending execution of the second handover to the second cell. Furthermore per ¶0042 that i.e. the delay suspends reporting to network for handover execution to a non-best neighbor cell reads on: the second cell having the lower priority, and furthermore per ¶0042 i.e. After a UE has determined a neighbor cell is a non-best neighbor cell, and after the non-best neighbor cell's TTT timer expires i.e. the handover to the a non-best neighbor cell is delayed after trigger condition for handover execution is met reads on: after the second execution condition is met for the second handover to the second cell.
based on the suspension condition being met and the first cell having the higher priority than the second cell for handover, suspending the execution of the second handover to the second cell having the lower priority within the allowed time duration (Yang ¶0037 see above; ¶0042 See above; ¶0039 See above; ¶0047 See above);
Which the office action respectfully contends and notes, discloses, teaches, and reads on subject claim limitations as follows: per ¶0042 i.e. After a UE has determined a neighbor cell is a non-best neighbor cell, i.e. and after the non-best neighbor cell's TTT timer expires, the UE does not immediately report the neighbor cell to a network reads on: based on the suspension condition being met, where per ¶0042 as applied to i.e. a neighbor cell is a non-best neighbor cell with respect to the best neighbor cell reads on: and the first cell having the higher priority than the second cell for handover , and furthermore i.e. Rather, the UE delays sending a measurement report, thereby delaying switching to the non-best neighbor reads on: suspending the execution of the second handover to the second cell having the lower priority , per ¶0042 i.e. the UE delays sending a measurement report, thereby delaying switching reads on: within the allowed time duration since sending to execute non best cell handover due expiry of non-best TTT timer expiry is delayed i.e. within the delay time.
Furthermore, in combining Wu and Yang the office action furthermore notes that: It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Wu with teachings of Yang (i.e. teachings derived from Yang and applied to elements not explicitly taught or not strongly suggested by Wu), since Yang enables UE to determine whether a neighbor cell is a best cell based on a combination of priority level and signal strength, such as when the neighbor cell has the same priority as another neighbor cell, the determination may be based on the priority level indicated by a serving network and also based on the neighbor cell signal strength (Yang - ¶0010; ¶0041).
The office furthermore notes that: While Wu in view of Yang teaches: A method comprising: receiving, by a wireless device from a first base station, at least one radio resource control configuration message for a conditional handover to a first cell or a second cell, wherein the first cell has a higher priority than the second cell for handover, wherein the conditional handover comprises one of a first handover to the first cell or a second handover to the second cell, wherein the at least one radio resource control configuration message comprises: a first execution condition for the first handover to the first cell having the higher priority; a second execution condition for the second handover to the second cell having a lower priority than the first cell; and a suspension condition indicating an allowed time duration for suspending execution of the second handover to the second cell having the lower priority after the second execution condition is met for the second handover to the second cellbased on the suspension condition being met and the first cell having the higher priority than the second cell for handover, suspending the execution of the second handover to the second cell having the lower priority within the allowed time duration; obtaining a measurement of at least one of received power of a serving cell, received power of the first cell, and received power of the second cell; comparing the measurement to at least one of the received power of the serving cell, the received power of the first cell, or the received power of the second cell; selecting, configuration message for the conditional handover and based on the comparing, a
Wu in view of Yang does not appear to explicitly teach or strongly teach (Note i.e. see italicized portions): a lower bound of the received power of the serving cell; a lower bound of the received power of the first cell; an upper bound of the received power of the second cell;

Furthermore, in combining Wu in view of Yang and WU2 with Deenoo the office action furthermore notes that: It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Wu in view of Yang and WU2 with teachings of Deenoo (i.e. teachings derived from Deenoo and applied to elements not explicitly taught or not strongly suggested by Wu in view of Yang and WU2 as referenced) , since Deenoo enables dedicated CFRA resource set signaling and selection procedure, beneficial for WTRUs with low mobility or a well-defined path (e.g. drones, high speed trains etc.) (Deenoo - ¶0132).
D. As such, the office action respectfully contends that applicant’s remarks or arguments as cited and directed to WU, WU2, and Deenoo are not persuasive since Wu in view of Yang and WU2 with Deenoo as relied upon, teaches and reads on each and every limitation of claim 1 in combination (i.e. also representative of parallel features in other independent claims 21, 22) as presented in the 35 U.S.C. 103 rejection presented herein (See office action).

While Wu teaches and reads on claim features noted above including target cell selection based upon per ¶0067 i.e. “the UE selects the candidate cell, which meets the corresponding handover condition firstly” which implies application of priority to selection of candidate cells within a timer that suspends or holds back individual handovers to allow adequate evaluation do determine which candidate the corresponding handover condition firstly,
Wu does not appear to explicitly teach or strongly suggest (Note – See italicized portions): the first cell having the higher priority; the second cell having a lower priority than the first cell; based on the suspension condition being met and the first cell having the higher priority than the second cell for handover, suspending the execution of the second handover to the second cell having the lower priority within the allowed time duration; a lower bound of the received power of the serving cell; a lower bound of the received power of the first cell; an upper bound of the received power of the second cell;
and furthermore Wu (i.e. in a single embodiment) does not appear to explicitly teach or strongly suggest(Note – See italicized portions): sending, a random-access preamble for a random access;
To teach portions of claim elements which Wu as referenced does not appear to explicitly teach or strongly suggest, the office action combines teachings from Yang from a similar field of endeavor associated with handovers and hand over conditions and reciting overlapping features, where:
Yang teaches: a conditional handover to a first cell or a second cell, wherein the first cell has a higher priority than the second cell for handover, wherein the conditional handover comprises one of a first handover to the first cell or a second handover to the second cell, a first execution condition for the first handover to the first cell having the higher priority; a second execution condition for the second handover to the second cell having a lower priority than the first cell; ( Yang ¶0037 … the UE starts separate timers for each neighbor cell having a signal strength value above the combined value. When this condition persists for a particular time duration, (referred to as the time to trigger (TTT)), for at least one neighbor cell, the UE sends a measurement report (MR) and triggers intra- or inter-frequency handover for the neighbor cell whose TTT timer expires first; ¶0039 […] the best neighbor cell(s) may not be reported for handover/redirection//cell change order if the time to trigger (TTT) timer for the best neighbor cell(s) has not expired […] Aspects of the present disclosure are directed to delaying or postponing reporting a neighbor cell to a network when a TTT timer expires for a neighbor cell that is not the best cell ; ¶0042…. After a UE has determined a neighbor cell is a non-best neighbor cell, and after the non-best neighbor cell's TTT timer expires, the UE does not immediately report the neighbor cell to a network. Rather, the UE delays sending a measurement report, thereby delaying switching to the non-best neighbor cell via hand-over; ¶0047 … When the TTT timer expires for the best neighbor cell(s), the UE sends a measurement report for the best neighbor cell(s)…when…the delay timer expires(and TTT timers are still running for non-best intra-RAT or inter-RAT neighbor cells), the UE sends a measurement report for a non-best neighbor cell;
NOTE-DISCLOSURE & TEACHING : per ¶0037 i.e. each neighbor cell having a signal strength value above the combined value and triggers intra- or inter-frequency handover for the neighbor cell reads on: a conditional handover where the handover is subject to conditions and rules associated with meeting per ¶0037 i.e. a signal strength value above the combined value and triggers such as TTT timer expiry. Furthermore, per ¶0037 where taught are i.e. separate timers for each neighbor cell, and where taught is i.e. the neighbor cell whose TTT timer expires first such as per ¶0042 for i.e. a non-best neighbor cell, and per ¶0047 for i.e. best neighbor cells reads on: to a first cell or a second cell. Furthermore per ¶0047 which teaches i.e. best neighbor cells reads on: wherein the first cell has a higher priority , in relation to per ¶0042 teaching i.e. a non-best neighbor cell reads on: than the second cell for handover . Furthermore per ¶0037 i.e. the neighbor cell whose TTT timer expires first such as applied individually to per ¶0047 i.e. When the TTT timer expires for the best neighbor cell(s), the UE sends a measurement report for i.e. the best neighbor for hand over reads on: wherein the conditional handover comprises one of a first handover to the first cell. Furthermore per ¶0037 i.e. the neighbor cell whose TTT timer expires first such as applied individually to per ¶0047 i.e. the delay timer expires, (and TTT timers are still running for non-best intra-RAT or inter-RAT neighbor cells), the UE sends a measurement report for a non-best neighbor cell reads on: or a second handover to the second cell. In both first cell and second cell cases, conditions and rules have to be met as taught to effect handover);
and a suspension condition indicating an allowed time duration for suspending execution of the second handover to the second cell having the lower priority after the second execution condition is met for the second handover to the second cell(Yang ¶0037 see above; ¶0042 See above; ¶0039 See above; ¶0047 See above;
NOTE-DISCLOSURE & TEACHING: per ¶0039 i.e. delaying or postponing reporting a neighbor cell to a network when a TTT timer expires for a neighbor cell that is not the best cell and per ¶0042 i.e. After a UE has determined a neighbor cell is a non-best neighbor cell, i.e. and after the non-best neighbor cell's TTT timer expires, the UE does not immediately report the neighbor cell to a network i.e. the delaying or postponing reporting a neighbor cell to a network and not immediately report the neighbor cell to a network as configured for the UE reads on: and a suspension condition indicating an allowed time duration associated with the configured delaying prior to reporting the neighbor cell for handover.
Furthermore per ¶0042 After a UE has determined a neighbor cell is a non-best neighbor cell, and after the non-best neighbor cell's TTT timer expires i.e. the UE does not immediately report the neighbor cell to a network i.e. the delay suspends reporting to network for handover execution to a non-best neighbor cell reads on: for suspending execution of the second handover to the second cell. Furthermore per ¶0042 that i.e. the delay suspends reporting to network for handover execution to a non-best neighbor cell reads on: the second cell having the lower priority, and furthermore per ¶0042 i.e. After a UE has determined a neighbor cell is a non-best neighbor cell, and after the non-best neighbor cell's TTT timer expires i.e. the handover to the a non-best neighbor cell is delayed after trigger condition for handover execution is met reads on: after the second execution condition is met for the second handover to the second cell) ;
based on the suspension condition being met and the first cell having the higher priority than the second cell for handover, suspending the execution of the second handover to the second cell having the lower priority within the allowed time duration (Yang ¶0037 see above; ¶0042 See above; ¶0039 See above; ¶0047 See above;
NOTE-DISCLOSURE & TEACHING : per ¶0042 i.e. After a UE has determined a neighbor cell is a non-best neighbor cell, i.e. and after the non-best neighbor cell's TTT timer expires, the UE does not immediately report the neighbor cell to a network reads on: based on the suspension condition being met, where per ¶0042 as applied to i.e. a neighbor cell is a non-best neighbor cell with respect to the best neighbor cell reads on: and the first cell having the higher priority than the second cell for handover , and furthermore i.e. Rather, the UE delays sending a measurement report, thereby delaying switching to the non-best neighbor reads on: suspending the execution of the second handover to the second cell having the lower priority , per ¶0042 i.e. the UE delays sending a measurement report, thereby delaying switching reads on: within the allowed time duration since sending to execute non best cell handover due expiry of non-best TTT timer expiry is delayed i.e. within the delay time);
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Wu with teachings of Yang, since Yang enables UE to determine whether a neighbor cell is a best cell based on a combination of priority level and signal strength, such as when the neighbor cell has the same priority as another neighbor cell, the determination may be based on the priority level indicated by a serving network and also based on the neighbor cell signal strength (Yang - ¶0010; ¶0041).
While Wu in view of Yang teaches: A method comprising: receiving, by a wireless device from a first base station, at least one radio resource control configuration message for a conditional handover to a first cell or a second cell, wherein the first cell has a higher priority than the second cell for handover, wherein the conditional handover comprises one of a first handover to the first cell or a second handover to the second cell, wherein the at least one radio resource control configuration message comprises: a first execution condition for the first handover to the first cell having the higher priority; a second execution condition for the second handover to the second cell having a lower priority than the first cell; and a suspension condition indicating an allowed time duration for suspending execution of the second handover to the second cell having the lower priority after the second execution condition is met for the second handover to the second cellbased on the suspension condition being met and the first cell having the higher priority than the second cell for handover, suspending the execution of the second handover to the second cell having the lower priority within the allowed time duration; obtaining a measurement of at least one of received power of a serving cell, received power of the first cell, and received power of the second cell; comparing the measurement to at least one of the received power of the serving cell, the received power of the first cell, or the received power of the second cell; selecting,
Wu in view of Yang does not appear to explicitly teach or strongly teach (Note i.e. see italicized portions): a lower bound of the received power of the serving cell; a lower bound of the received power of the first cell; an upper bound of the received power of the second cell;
and furthermore Wu in view of Yang (i.e. Wu i.e. in a single embodiment) does not appear to explicitly teach or strongly suggest(Note – See italicized portions): sending, a random-access preamble for a random access;

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Wu in view of Yang and WU2 and Deenoo, further with the teachings of Deenoo, since Deenoo enables dedicated CFRA resource set signaling and selection procedure, beneficial for WTRUs with low mobility or a well-defined path (e.g. drones, high speed trains etc.) (Deenoo - ¶0132).

Furthermore Yang teaches: whereinthe set of selection rules comprises: selecting the first cell based on the first execution condition being met (Yang ¶0047 see claim 1; NOTE-DISCLOSURE & TEACHING: per ¶0047 i.e. When the TTT timer expires for the best neighbor cell(s), the UE sends a measurement report for the best neighbor cell(s).reads on: wherein the set of selection rules comprises: selecting the first cell , per ¶0047 i.e. When the TTT timer expires for the best neighbor cell(s) reads on: based on the first execution condition being met );

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Wu in view of Yang and WU2 and Deenoo, further with the teachings of Yang, since Yang enables UE to determine whether a neighbor cell is a best cell based on a combination of priority level and signal strength, such as when the neighbor cell has the same priority as another neighbor cell, the determination may be based on the priority level indicated by a serving network and also based on the neighbor cell signal strength (Yang - ¶0010; ¶0041).

Where applicable, minor differences between claims are noted as appropriate).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Wu in view of Yang, WU2, Deenoo and Purkayastha, further with the teachings of Yang, since Yang enables UE to determine whether a neighbor cell is a best cell based on a combination of priority level and signal strength, such as when the neighbor cell has the same priority as another neighbor cell, the determination may be based on the priority level indicated by a serving network and also based on the neighbor cell signal strength (Yang - ¶0010; ¶0041).

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Wu in view of Yang, WU2 and Deenoo and Purkayastha further with teachings of Purkayastha, since Purkayastha enables a target base station to reserve CFRA resources (e.g., such as CFRA time-frequency resources, a CFRA preamble, a dedicated RACH preamble, etc.) for a UE to reduce latency associated with a random access procedure should CHO be triggered for the target base station (Purkayastha - ¶0097).

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Wu in view of Yang, WU2 and Deenoo with teachings of Purkayastha, since Purkayastha enables a target base station to reserve CFRA resources (e.g., such as CFRA time-frequency resources, a CFRA preamble, a dedicated RACH preamble, etc.) for a UE to reduce latency associated with a random access procedure should CHO be triggered for the target base station (Purkayastha - ¶0097).

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Wu in view of Yang, WU2, Deenoo and Purkayastha with teachings of SAHLIN, since SAHLIN enables a network node (e.g., gNB) to transmit the RAR in another beam than related SSB, and allows the network to define the gNB behavior for a case of many-to-one associations between SSB and PRACH preamble indices and includes enabling the use of “silent nodes” for PRACH detection and RAR transmission in an NR network, which improves detection performance in heterogeneous networks (SAHLIN - ¶0047).

In action 390, target base station 308 may monitor and detect a random access preamble ; ¶0088 … Target base station 308 may monitor the beam-related PRACH and/or RACH resources using the same spatial domain filter that is used for transmitting at least one of the SS block index or the CRI indicated to UE 302 in the Handover Command; NOTE-DISCLOSURE & TEACHING : each individual coarse beams and fine beams utilized by UE to access the target cell via RACH are associated with spatial domain filter that is used for transmitting at least one of the SS block index or the CRI indicated in the Mobility control information transparently from target i.e. reads on: wherein: the first beam is associated with at least one first spatial domain filter ); and one second beam (Cheng – FIG. 1 & ¶0067…. target base station 108 broadcasts coarse beams 116x, 116y and 116z, and fine beams 118p, 118q, 118r, 118s, 118t, 118u, 118v, 118w, 118x, 118y and 118z in the coverage area of target cell 110; NOTE-DISCLOSURE & TEACHING : coarse beams 116x, 116y and 116z, and fine beams 118p, 118q, 118r, 118s, 118t, i.e. reads on: at least one second beam in addition to a first beam ) is associated with at least one second spatial domain filter (Cheng FIG. 3 & ¶0084… See above; ¶0087…. See above ; ¶0088 … See above; NOTE-DISCLOSURE & TEACHING : each individual coarse beams and fine beams i.e. including the second beam utilized by UE to access the target cell via RACH are associated with spatial domain filter that is used for transmitting at least one of the SS block index or the CRI indicated in the Mobility control information transparently from target i.e. reads on: wherein: the second beam is associated with at least one first spatial domain filter );
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Wu in view of Yang, WU2 and Deenoo with teachings of Cheng, since Cheng enables performing beam refinement during a handover procedure such that the target base station can apply higher data rate and better link quality immediately after the handover procedure to maintain the quality of service. (Cheng - ¶0158).
