Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
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) 1-30 are rejected under 35 U.S.C. 103 as being unpatentable over Bae (EP 4572511) in view of Jeon (US 20200314917).
Regarding claim 1, Bae discloses a user equipment (UE), comprising: one or more memories storing processor-executable code; and one or more processors coupled with the one or more memories (fig. 2) and individually or collectively operable to execute the code to cause the UE to:
receive, from a network entity, a configuration message indicating a plurality of random access channel resource sets for the UE, wherein each random access channel resource set of the plurality of random access channel resource sets is associated with a respective (fig. 13, s1301, s1401, [0132][0155], receive a configuration related to plurality of random access channel occasion; [0166] the BS may provide a configuration related to a plurality of RO groups; parameter preambleReceivedTargetPower may be configured for each PRACH resource or RO group, which may be used to determine the PRACH target reception power through MAC layer operations);
select a random access channel resource set from the plurality of random access channel resource sets based at least in part on an uplink power value associated with the UE ([0141], the UE may determine a PRACH resource or RO group to use for random access based on the PRACH transmission power determined for each of the plurality of PRACH resources or RO groups); and
transmit, to the network entity, one or more random access messages in accordance with one or more resources of the random access channel resource set based at least in part on selecting the random access channel resource set ([0141], the UE may perform random access using a RACH resource or RO group with transmission power less than the UEconfigured maximum output power (PCMAX,f,c )(that is, a RACH resource or RO group with the largest transmission power among RACH resources or RO groups where PPRACH,b,f,c(i) is determined to be less than PcMAX,f,c).
Bae does not explicitly disclose each random access channel resource set of the plurality of random access channel resource sets is associated with a respective
Jeon discloses each random access channel resource set of the plurality of random access channel resource sets is associated with a respective (Jeon, fig. 18C, [0373][0400-401], the target power range can be (-202, -60)).
It would have been obvious to a person of ordinary skill in the art before the time of effective filing to combine the teachings as given by Bae with the teachings given by Jeon. The motivation for doing so would have been to reduce delay in determining a success or a failure of a random access procedure (Jeon, [0004]).

PREAMBLE_POWER_RAMPI NG_COUNTER is a variable that indicates the number of times the preamble power is ramped).
Regarding claim 7, 19, Bae and Jeon disclose the UE of claim 6, wherein:
a first random access occasion comprises two or more portions, each of the two or more portions respectively corresponding to a first random access channel resource set associated with a first random access channel format (Bae, fig. 15, 19; Jeon, fig. 18, [0373][0400-401]);
a second random access occasion comprises a single portion that corresponds to a second random access channel resource set associated with a second random access channel format different than the first random access channel format (Bae, fig. 15, 19; Jeon, fig. 18, [0373][0400-401]); and
the first random access occasion and the second random access occasion occupy a same set of time domain resources (Bae, fig. 15, 19, the UL and DL resources are assigned to the UE through resource allocation by the BS. Resource allocation may include time domain resource allocation).
