DETAILED ACTION
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
RCE filed 1/23/2026 is acknowledged.
Claims 1, 8, 13, 19, and 26 have been amended. Previous rejections of claims 13-18 under 35 USC 112(b) are withdrawn in light of the present amendments.
Claims 1-30 remain pending.
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(d):
(d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers.
Claim 21 is rejected under 35 U.S.C. 112(d) as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends.
Based on the present amendments to claim 19, from which claim 21 depends, the limitations of claim 21 fail to further limit the subject matter of claim 19.
Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements.

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 4 and 25 are rejected under 35 U.S.C. 103 as being unpatentable over Zhang in view of Freda.
Regarding claims 4 and 25,
Zhang does not expressly disclose the layer 2 relay initial configuration of the UE is associated with signaling radio bearer zero (SRB0) traffic.
Freda discloses analogous art (Title: Device to Device Relay Connection Establishment and Configuration) including layer 2 relay initial configuration of the UE is associated with signaling radio bearer zero (SRB0) traffic (paragraphs 251-255, 283-285; relay WTRU configuration relaying SRB0 to dedicated SL radio bearers).
It would have been obvious to one of ordinary skill in the art before the time of effective filing to modify Zhang by providing layer 2 relay initial configuration of the UE is associated with signaling radio bearer zero (SRB0) traffic, as shown by Freda, thereby ensuring consistent configuration of the SLRBs in an end-to-end fashion.
Claim 9 is rejected under 35 U.S.C. 103 as being unpatentable over Freda in view of Zhang.
Regarding claim 9,
Freda discloses non-access stratum (paragraph 65) and access stratum (paragraph 80, 89-93, 165-166, 189) signaling related to relay service, but fails to expressly show initiating the connection with the network entity comprises at least one of: performing a successful authentication and security set up with the network entity during a NAS registration and service request procedure, or performing a successful AS security setup with the network entity during RRC connection setup procedure.
Zhang discloses analogous art (Title: Methods for Relay Connection Establishment) including performing a successful authentication and security set up with the network entity during a NAS registration and service request procedure, or performing a successful AS security setup with the network entity during RRC connection setup procedure (Fig. 5, S5-7; paragraph 6, 24-26, 33, 34; NAS or AS authentication/security procedure associated with relay configuration).
It would have been obvious to one of ordinary skill in the art before the time of effective filing to modify Freda by performing a successful authentication and security set up with the network entity during a NAS registration and service request procedure, or performing a successful AS security setup with the network entity during RRC connection setup procedure, as shown by Zhang, thereby ensuring the relay UE is authorized to support the requested relay service.
Response to Arguments
Applicant's arguments filed 1/23/2026 have been fully considered but they are not persuasive.
In the Remarks on pg. 12 of the Amendment, Applicant contends the previously cited portions of Zhang do not disclose or suggest a NAS setup procedure that comprises an authentication and security procedure, as now claimed via the present amendment.
The Examiner respectfully disagrees. Zhang clearly discloses a NAS setup procedure that comprises an authentication and security procedure. See Fig. 5, S5.7 and paragraph 26, as now cited in the rejection. Therefore, rejections under 35 USC 102 based on Zhang are properly maintained.
In the Remarks on pg. 13-14 of the Amendment, Applicant contends the previously cited portions of Freda do not disclose transmitting a request to establish a layer 2 relay service to a second UE and receiving, from the network entity, a layer 2 relay initial configuration based on initiating the connection and transmitting the request, as now claimed via the present amendment.
The Examiner respectfully disagrees. Freda clearly shows transmitting a request to establish a layer 2 relay service to a second UE and receiving, from the network entity, a layer 2 relay initial configuration based on initiating the connection and transmitting the request. See Fig. 8, steps 802-803, 806b, Fig. 9, step 915, and paragraphs 160, 201, 213, in which the remote WTRU send a connection request to a selected/best relay WTRU and then Fig. 8, step 807 and paragraphs 160, 208-210, 214, and 255 in which the remote WTRU receives configuration directly from the network, as now cited in the rejection. Therefore, rejections under 35 USC 102 based on Freda are properly maintained.
