CTFR 18/686,374 CTFR 83583 Detailed Action 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. This is a final action for application number 18/686,374 in response to an amendment filed on 04/20/2026; the original application filed on 02/23/2024. Claims 21, 23-31 and 33-40 are currently pending and have been considered below. Claims 21 and 31 are independent claims. Claims 1-20, 22 and 32 have been cancelled. Response to Arguments Applicants’ arguments in the instant Amendment, filed on 04/20/2026, with respect to limitations listed below, have been fully considered but they are not persuasive. Applicant’s arguments: “Abedini does not disclose providing specific information regarding beams to be used on an access link; wherein the information on the one or more beams are configured as information indicating index(es) of the one or more beams or information indicating codebook entry(ies) of the one or more beams”. The Examiner disagrees with the Applicants. The Examiner respectfully submits that Abedini et al. teaches receiving, from a base station and on a control link between the base station and the repeater, [repeaters in the plurality of repeaters are configured to receive signals from first wireless communication devices, (Abedin et al., Paragraph 6)] , information on one or more beams used for transmissions or receptions on an access link between the repeater and a terminal, [the configuration information may be associated with configuring a value for a parameter. The parameter may be associated with, for example, a maximum number of beams or a maximum number of SSBs that can be used by a given repeater of the plurality of repeaters (e.g., a maximum number of beams a repeater can use on a service-side), (Abedin et al., Paragraphs 95)] , wherein the information on the one or more beams are configured as information indicating index(es) of the one or more beams or information indicating codebook entry(ies) of the one or more beams , [the wireless communication device may select an SSB to be used in association with performing an access procedure based at least in part on the configuration information (e.g., the wireless communication device may select an SSB corresponding to an SSB index indicated as one for which repeaters are to forward signals), (Abedini et al., Paragraph 102)]. Please further see Paragraph [0072], “An antenna 510/510′ includes one or more antenna elements capable of being configured for beamforming. In some aspects, as illustrated in FIG. 5A, millimeter wave repeater 500 may include one or more phased array antennas 510, which may be referred to as a phased array because phase values and/or phase offsets of the antenna elements may be configured to form a beam, with different phase values and/or phase offsets being used for different beams”. Please further see Paragraph [0084], “additional examples of configurations that may be provided via the backhaul link include a transmit power configuration for the access link (e.g., a configuration indicating a transmit power to be used when forwarding a signal) and an on-off configuration to be used on the access link (e.g., a configuration indicating whether the repeater is to forward signals or refrain from forwarding signals)”. Please further see Paragraph [0212], “wherein the parameter is associated with a maximum number of beams that can be used by a repeater of the plurality of repeaters”. The examiner would like to further indicate that the configuration information in the cited paragraphs above all include specific information about the beams. The Examiner respectfully suggests that the claim be further amended and details in the specification be incorporated to distinguish the claimed invention over prior art of record. Should the Applicant desire an interview to further clarify the claim interpretation/rejections, please contact the Examiner at 571-270-1921 to schedule an interview.

Claim Rejections - 35 USC § 103 07-20-aia AIA 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. 07-21-aia AIA Claim s 24 and 34 are rejected under 35 U.S.C. 103 as being unpatentable over Abedini et al. (US 2021/0306065 A1) in view of Yi et al. (EP 4637064 A1) . Regarding claims 24 and 34 , Abedin et al. teaches the method according to claim 23, wherein when the information on the one or more beams is received from the base station through the DCI, the DCI is monitored in a physical downlink control channel (PDCCH) search space set configured by the base station on the control link, [The resources that are to carry the signals associated with the set of SSBs may include, for example, resources associated with carrying physical downlink control channels (PDCCHs) associated with scheduling RMSI associated with the set of SSB, (Abedin et al., Paragraph 93) , Abedin et al. fails to explicitly teach that the DCI has a format 2_X (X is 0 or a natural number), Yi et al. teaches that DCI format 2_0, 2_1, 2_2, 2_3, 2_4, 2_5 and 2_6 may be used for a group-common DCI transmission. Each format of DCI format 2_x may be used for different information, (Yi et al., Paragraph 246) , It would have been obvious to one of ordinary skill in the art at the time of the invention was made to modify Abedini et al. by including that that the DCI has a format 2_X (X is 0 or a natural number), (Yi et al., Paragraph 246) , in order to notify a group of UEs of a physical resource block and OFDM symbol where the UE may assume no transmission is intended to the UE, (Yi et al., Paragraph 208). Conclusion 07-39 AIA THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action.
