Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 1-5, 9-17 and 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Jung et al. (Pub. No.: 2022/0377812 A1), herein Jung and Schober et al. (Pub. No.: 2024/0172288), herein Schober.
As to claim 1, Jung teaches a user equipment (UE), comprising:
one or more memories storing processor-executable code (Jung Fig. 15 memory); and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to (Jung Fig. 15 processor):
receive first control signaling that schedules a first set of random access channel occasions, wherein the first control signaling indicates a first power control parameter (Jung [0023] According to a possible embodiment, first transmission power can be determined for a first PRACH preamble in a 2-step random access procedure based on a first set of power control parameters. The first PRACH preamble can be transmitted in the 2-step random access procedure based on the first transmission power and [0166] According to a possible embodiment, information of at least one dedicated PRACH preamble and at least one corresponding set of PRACH occasions for the 2-step random access procedure can be received when the type of random access procedure is a 2-step random access procedure)
transmit a first random access channel message via a first random access channel occasion in accordance with the first power control parameter, wherein the first set of random access channel occasions comprises the first random access channel occasion (Jung [0166] Transmitting the MsgA transmission can include transmitting a dedicated PRACH preamble of the at least one dedicated PRACH preamble on a PRACH occasion of a set of PRACH occasions of the at least one set of PRACH occasions and [0023] The first PRACH preamble can be transmitted in the 2-step random access procedure based on the first transmission power);
and
transmit a second random access channel message via a second random access channel occasion in accordance with a second power control parameter based at least in part on the activation of the additional random access channel occasion (Jung [0023] Second transmission power can be determined based on the first set of power control parameters and a second set of power control parameters for a subsequent second PRACH preamble transmission (additional random access channel occasion)
Jung does not teach
receive second control signaling that indicates activation of an additional random access channel occasion
However Schober does teach
receive second control signaling that indicates activation of an additional random access channel occasion (Schober [0015] an additional control resource set and/or an additional sets of the RACH occasions for the random access preamble may be transmitted);
It would have been obvious before the effective filing date of the claimed invention to combine the teachings of Jung with Schober, because Schober teaches us [0015] Thus it will be seen that, in such embodiments, an additional control resource set for the random access response and/or an additional sets of the RACH occasions for the random access preamble may be transmitted at the same time as the other respective sets, over different, non-overlapping frequencies, the network apparatus choosing which control resource set to use. This advantageously increases the overall capacity of the network, as the apparatus may be able to communicate with an increased number of reduced capability user apparatuses by configuring one or more of them to utilise the additional sets instead of the other respective sets—e.g. where a single respective control resource set and/or set of RACH occasions provides fewer configuration options than that required by the number of reduced capability user apparatuses in communication with the apparatus.
As to claim 13, Jung teaches a method for wireless communications at a user equipment (UE), comprising:
receiving first control signaling that schedules a first set of random access channel occasions, wherein the first control signaling indicates a first power control parameter parameter (Jung [0023] According to a possible embodiment, first transmission power can be determined for a first PRACH preamble in a 2-step random access procedure based on a first set of power control parameters. The first PRACH preamble can be transmitted in the 2-step random access procedure based on the first transmission power and [0166] According to a possible embodiment, information of at least one dedicated PRACH preamble and at least one corresponding set of PRACH occasions for the 2-step random access procedure can be received when the type of random access procedure is a 2-step random access procedure)
transmitting a first random access channel message via a first random access channel occasion in accordance with the first power control parameter, wherein the first set of random access channel occasions comprises the first random access channel occasion (Jung [0166] Transmitting the MsgA transmission can include transmitting a dedicated PRACH preamble of the at least one dedicated PRACH preamble on a PRACH occasion of a set of PRACH occasions of the at least one set of PRACH occasions and [0023] The first PRACH preamble can be transmitted in the 2-step random access procedure based on the first transmission power);
transmitting a second random access channel message via a second random access channel occasion in accordance with a second power control parameter based at least in part on the activation of the additional random access channel occasion (Jung [0023] Second transmission power can be determined based on the first set of power control parameters and a second set of power control parameters for a subsequent second PRACH preamble transmission (additional random access channel occasion)
Jung does not teach
receive second control signaling that indicates activation of an additional random access channel occasion
However Schober does teach
receive second control signaling that indicates activation of an additional random access channel occasion (Schober [0015] an additional control resource set and/or an additional sets of the RACH occasions for the random access preamble may be transmitted);
It would have been obvious before the effective filing date of the claimed invention to combine the teachings of Jung with Schober for the same reasons stated in claim 1.
As to claim 20, Jung teaches a non-transitory computer-readable medium storing code for wireless communications by a user equipment (UE), the code comprising instructions executable by one or more processors to:

The first PRACH preamble can be transmitted in the 2-step random access procedure based on the first transmission power and [0166] According to a possible embodiment, information of at least one dedicated PRACH preamble and at least one corresponding set of PRACH occasions for the 2-step random access procedure can be received when the type of random access procedure is a 2-step random access procedure);
transmit a first random access channel message via a first random access channel occasion in accordance with the first power control parameter, wherein the first set of random access channel occasions comprises the first random access channel occasion (Jung [0166] Transmitting the MsgA transmission can include transmitting a dedicated PRACH preamble of the at least one dedicated PRACH preamble on a PRACH occasion of a set of PRACH occasions of the at least one set of PRACH occasions and [0023] The first PRACH preamble can be transmitted in the 2-step random access procedure based on the first transmission power);
transmit a second random access channel message via a second random access channel occasion in accordance with a second power control parameter based at least in part on the activation of the additional random access channel occasion (Jung [0023] Second transmission power can be determined based on the first set of power control parameters and a second set of power control parameters for a subsequent second PRACH preamble transmission (additional random access channel occasion)
Jung does not teach

However Schober does teach
receive second control signaling that indicates activation of an additional random access channel occasion (Schober [0015] an additional control resource set and/or an additional sets of the RACH occasions for the random access preamble may be transmitted);
It would have been obvious before the effective filing date of the claimed invention to combine the teachings of Jung with Schober for the same reasons stated in claim 1.

In another implementation, the UE can assume that PRACH preamble power control parameters for the 2-step random access procedure are the same as PRACH preamble power control parameters for the 4-step random access procedure, if they are not separately configured)
Claim 15 is rejected for the same reasons stated in claim 3.
As to claim 4, the combination of Jung and Schober teach the UE of claim 1, wherein, to transmit the second random access channel message, the one or more processors are individually or collectively operable to execute the code to cause the UE to:

In another implementation, the UE can assume that PRACH preamble power control parameters for the 2-step random access procedure are the same as PRACH preamble power control parameters for the 4-step random access procedure, if they are not separately configured)
Claim 17 is rejected for the same reasons stated in claim 5.
As to claim 9, the combination of Jung and Schober teach the UE of claim 1, wherein: the first power control parameter comprises a first ramping increment between subsequent random access channel messages, and the second power control parameter comprises a second ramping increment between subsequent random access channel messages different from the first ramping increment between subsequent random access channel messages (Jung [0145] At least some embodiments can provide for PRACH power setting when a UE fallbacks from 2-step RACH to 4-step RACH.

Claim(s) 6 and 18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Jung, Schober and Pan et al. CN 110149684 B (translated), herein Pan.
As to claim 6, the combination of Jung and Schober teach the UE of claim 1,
Jung nor Schober teach
wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to: reset a power control accumulator parameter based at least in part on the activation, wherein the second power control parameter comprises the power control accumulator parameter
However Pan does teach
wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to: reset a power control accumulator parameter based at least in part on the activation, wherein the second power control parameter comprises the power control accumulator parameter (Pan [0117] determining the output value of the closed-loop power control accumulator shared by the first BWP and the second BWP, wherein the shared closed-loop power control accumulator is reset when the active BWP is switched from the first BWP to the second BWP.
It would have been obvious before the effective filing date of the claimed invention to combine the teachings of Jung and Schober with Pan, because Pan [0005] teaches us the BWP switching indication information is used for indicating the terminal device to switch the active BWP from the first BWP to the second BWP, and determining the output value of the closed loop power control accumulator of the second BWP.
Claim 18 is rejected for the same reasons stated in claim 6.
