Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 15-22 and 25-32 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
In regard to Claim 15, Claim 15 recites: “in case that a serving cell is a primary secondary cell (PSCeII) and a secondary cell group (SCG) is deactivated” (emphasis added). It is unclear whether or not a “case” actually occurs and is required. The examiner suggests adding in response to into Claim 15, so that the above claim excerpt includes: in response to a serving cell is a primary secondary cell (PSCeII) and a secondary cell group (SCG) is deactivated.
Claims 16-22 are rejected through dependence from Claim 15.
In regard to Claim 25, Claim 25 recites: “in case that a serving cell is a primary secondary cell (PSCeII) and a secondary cell group (SCG) is deactivated” (emphasis added). It is unclear whether or not a “case” actually occurs and is required. The examiner suggests adding in response to into Claim 25, so that the above claim excerpt includes: in response to a serving cell is a primary secondary cell (PSCeII) and a secondary cell group (SCG) is deactivated.
Claims 26-32 are rejected through dependence from Claim 25.
Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:

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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claim(s) 17 and 27 is/are rejected under 35 U.S.C. 103 as being unpatentable over Da Silva in view of Zhang et al. (Pub. No.: US 20220272752 A1), hereafter referred to as Zhang ‘752.

The parameters lbt-FailureDetectionTimer may be programed or configured, such as by RRC. The timer is reset or restarted with every LBT failure indication for the beam, Para. 70).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Zhang ‘752 with the teachings of Da Silva since Zhang ‘752 provides a technique for managing timers based on beam failure operations, which can be introduced into the arrangement of Da Silva to permit the efficient management of timers in relation to BFD actions.
In regard to Claim 27, as presented in the rejection of Claim 25, Da Silva teaches reporting the beam failure of the PSCeII to the upper layer.

Zhang ‘389 teaches in case that the serving cell is a primary cell (PCell) or the serving cell is the PSCelI and the SCG is activated, initiating a random access procedure on the PCell or the PSCelI (UE 510 determines whether to perform a random access channel (RACH) to the new PSCell/SCG according to the (de) activation state of the old PSCell/SCG. The new PSCell/SCG may inherit the PSCell/SCG (de) activation state from the old PSCell/SCG. If the old PSCell/SCG is activated, the new PSCell/SCG is thus activated, and UE 510 may perform a RA procedure or send a data packet directly to the new PSCell/SCG, Para. 147, FIG. 10).

The BFI-counter is supervised by a BFD timer. Each time the UE receives a new BFI indication, the BFD timer is triggered (started or restarted), and the BFI counter is incremented. If the BFD timer expires, the BFI-counter is reset. The BFI counter and BFD timer may be configured per TRP, per BFD-RS set or per serving beam or serving beam set, Para. 55. The TRP may configure the UE explicitly by using the BFD-RS for corresponding CORESET sets, Para. 58. Each of the predefined counter value and the predefined threshold value used in the above-defined rules may mean a value configured by the network in which the UE 500 communicates with the first and second TRPs, Para. 90).

Claim(s) 22, 24, 32 and 34 is/are rejected under 35 U.S.C. 103 as being unpatentable over Da Silva in view of Uesaka et al. (Pub. No.: US 20230354453 A1), hereafter referred to as Uesaka.
In regard to Claim 22, as presented in the rejection of Claim 15, Da Silva teaches the beam failure detection configuration information.
Da Silva fails to teach the beam failure detection configuration information includes fourth information on a detection resource, and wherein the detection resource is one of a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS).
Uesaka teaches the beam failure detection configuration information includes fourth information on a detection resource, and wherein the detection resource is one of a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS) (Beam failure is detected in L1 (i.e., PHY) when the BLER of a (hypothetical) PDCCH is above a threshold for a certain time. This step is also called beam failure detection (BFD), In the second step, new candidate beams are identified by measuring beam identification RS, such as CSI-RS or SSB, Para. 109. The network node configures the UE's candidate beam reference signal list (e.g., via RRC signaling), which includes SSB ID(s) and/or CSI-RS resource ID(s), Para. 118).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Uesaka with the teachings of Da Silva since Uesaka provides a technique for configuring UEs with SSB IDs and/or CSI-RS resource IDs in relation to beam failure detection, which can be introduced into the arrangement of Da Silva to permit a network node to inform a UE of specific resources for the detection of beam failures.
In regard to Claim 24, as presented in the rejection of Claim 23, Da Silva teaches the beam failure detection configuration information.
Da Silva fails to teach the beam failure detection configuration information includes second information on a maximum count value for triggering a beam failure recovery, third information on a beam failure detection timer, and fourth information on a detection resource, and wherein the detection resource is one of a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS).

The network may also configure a timer (e.g., beamFailureRecoveryTimer) with a particular value (e.g., 100 ms), Para. 118).
