DETAILED ACTION
Response to Arguments
Applicant’s arguments with respect to claims 1-20 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
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.
Claims 1-11 and 14-20 are rejected under 35 U.S.C. 103 as being unpatentable over Nattha et al. (US 20230077982 A1) in view of Park et al. (US 20190132066 A1)
Considering claims 1, 17, Nattha teaches a method for wireless communication, comprising:
receiving, by a terminal device (UE), first information from a network device (BS 904), wherein the network device corresponds to a serving cell of the terminal device (Fig.9, [0066]-[0067] At 906, the base station 904 may transmit a beam refinement configuration to the UE 902), wherein the first information an indicator indicating whether transmit sweeping (Fig.1, 5-9, [0061]-[0063], [0072] UE may receive a beam refinement configuration),
determining, based on the first information, at least one of a first transmit beam or a first receive beam on a first time unit (Fig.1, 9-10, [0037] The UE 104 may receive the beamformed signal from the base station 180 in one or more receive directions 182″. The UE 104 may also transmit a beamformed signal to the base station 180 in one or more transmit directions, [0074] UE may identify the refined beam for the serving cell based on the sweeping of the multiple beams).
Nattha do not clearly teach an indicator indicating whether transmit beam sweeping performed by a first neighbor cell is synchronized with transmit beam sweeping performed by the serving cell.
Park teaches an indicator indicating whether transmit beam sweeping performed by a first neighbor cell (gNB2) is synchronized with transmit beam sweeping performed by the serving cell (gNB1) (Fig.20-21, [0229] synchronization signal and/or receiving a signal…. synchronization signal scheduling information and/or a synchronization signal sequence may be used to identify a swept beam, [0230], [0235]).

Considering claim 7, Nattha teaches wherein the first information includes the offset value of the transmit beam sweeping performed by the first neighbor cell relative to the transmit beam sweeping performed by the serving cell (Fig.5-9, [0041], [0061]-[0063] FIG. 5, a time delta Δt 506 may be present between the serving cell SSB X 502 and the neighbor cell SSB X 504), the offset value includes at least one of a time offset value or a direction offset value, and the beam direction of the first receive beam is determined according to a transmit beam of the serving cell on the first time unit and the offset value (Fig.5-9, [0041], [0061]-[0063] FIG. 5, a time delta Δt 506 may be present between the serving cell SSB X 502 and the neighbor cell SSB X 504).
Considering claim 8, Nattha teaches wherein the first receive beam is one of a plurality of receive beams for the terminal device to perform beam sweeping on at least one of the serving cell or the first neighbor cell, and a number of receive beams of the terminal device is different from a number of transmit beams of one or both of the serving cell and the first neighbor cell.
Considering claim 9, Nattha teaches wherein the first neighbor cell is any one of a plurality of neighbor cells corresponding to the terminal device, the first information is used for the terminal device to determine a plurality of transmit beams corresponding to the plurality of neighbor cells (Fig.1, 5-9, [0037], [0061]), and the method further includes: determining, by the terminal device, one or more receive beams corresponding to the plurality of neighbor cells via the plurality of transmit beams, wherein the one or more receive beams are used for the terminal device to measure the plurality of neighbor cells (Fig.1, 5-9, [0037], [0061]).
