Claim Rejections - 35 USC § 103
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 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.
Claims 5, 7-8, 12-15 are rejected under 35 U.S.C. 103 as being unpatentable over Yuki et al. (US 20240306015 A1, hereinafter Yuki) in view of Liina et al. (US 20230413077 A1, hereinafter Liina).
Claim 5: Yuki does not explicitly teach the apparatus according to claim 4, wherein, the radio resource control signaling includes a first indication field, the first indication field being used for indicating a purpose of the third reference signal, wherein if the radio resource control signaling configures reference signal(s) for transmission reception point-specific beam failure detection, a value of the first indication field is configured as being of a radio link failure.
Liina, from the same or similar field of endeavor, teaches the radio resource control signaling includes a first indication field, the first indication field being used for indicating a purpose of the third reference signal ([0117-0118], RRC configuration message including the first set of activated TCI states includes a third TCI state that indicates a third reference signal, the third TCI state is for a third CORSET belonging to the first CORESET group and the first set of activated TCI is configured for first physical cell ID PCI, Fig. 1, 2, [0106-0107], disclose UE perform beam failure detection via PCI associated TRP based on the set of reference signals. Wherein a beam failure with respect to the first PCI is interpreted as a purpose of the third reference signal), wherein if the radio resource control signaling configures reference signal(s) for transmission reception point-specific beam failure detection, a value of the first indication field is configured as being of a radio link failure ([0030], determining whether a beam failure with respect to the first
Physical Cell Identifier PCI has occurred based on the first set of reference signals; and determining whether a beam failure with respect to the second PCI has occurred based on the second set of reference signals, [0057-0058], one implication is that resources to be monitored for BFD can be reference signals associated to more than one PCI, wherein different PCIs may be transmitted by different TRPs).
Yuki and Liina are both considered to be analogous to the claimed invention because they are in the same field of wireless communication. Therefore, it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to combine the system of Yuki and the features of the first indication field being used for indicating a purpose of the third reference signal as taught by Liina, for the benefit for allowing UE to monitor reference signals associated to more than one PCI for beam Failure detection BFD (paragraph [0057]), also allowing UE to monitor reference signals associated to more than one serving cell within the serving cell for beam Failure detection BFD (paragraph [0058]).
Claim 7: Yuki does not explicitly teach the apparatus according to claim 6, wherein, the information on a transmission configuration indication state includes a transmission configuration indication state identifier.
Liina, from the same or similar field of endeavor, teaches the information on a transmission configuration indication state includes a transmission configuration indication state identifier ([0062-0063], disclose each Serving Cell is configured with TCI state IDs that can be associated with different PCIs).
The motivation for combining Yuki and Liina regarding to the claim 5 is also applied to claim 7.
Claim 8: Yuki does not explicitly teach the apparatus according to claim 1, wherein the first reference signal does not include a second reference signal for transmission reception point-specific beam failure detection, and a lower layer determines the second reference signal via a transmission configuration indication state received via a physical downlink control channel, and determines that the second reference signal is associated with a control resource set pool.
Liina, from the same or similar field of endeavor, teaches wherein the first reference signal does not include a second reference signal for transmission reception point-specific beam failure detection, and a lower layer determines the second reference signal via a transmission configuration indication state received via a physical downlink control channel, and determines that the second reference signal is associated with a control resource set pool ([0009], If the UE is not provided q0 by failureDetectionResources, the UE determines the set q0 to include periodic CSI-RS resource configuration indexes with same values as the RS indexes in the RS sets indicated by TCI-State for respective Control Resource Sets CORESETs that the UE uses for monitoring PDCCH, if there are two RS indexes in a TCI state, the set q0 includes RS indexes with QCL-Type D configuration for the corresponding TCI
States. [0066-0067], If no SSB/CSI-RS are configured as beam detection reference
signals, the UE should assume that the reference signals used as QCL-type D sources for the TCI states used for the CORESETs should be used as beam detection reference
signals instead, these beam failure detection reference signals should then be grouped according to the CORESETPoolIndexes, beam failure detection reference signal groups can be defined for Multi-TRP features based on single-PDCCH scheduling when no SSB/CSI-RS are explicitly configured as beam detection reference signals).
Yuki and Liina are both considered to be analogous to the claimed invention because they are in the same field of wireless communication. Therefore, it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to combine the system of Yuki and the features of determining the second reference signal via a transmission configuration indication state received via a physical downlink control channel as taught by Liina, for the benefit for allowing UE to group beam failure detection reference signal
for Multi-TRP features based on single-PDCCH scheduling when no SSB/CSI-RS are explicitly configured as beam detection reference signals (paragraph [0066-0067]).

Liina, from the same or similar field of endeavor, teaches wherein the processor circuitry is further configured to: enable a medium access control entity of a terminal equipment to set a counter of a beam failure instance of a beam failure detection reference signal set of a serving cell to be 0 in a case where the medium access control control element signaling is associated with the beam failure detection reference signal set of the serving cell ([0021], table 4, disclose setting BFI_COUNTER to 0 based on beamFailureDetectionTimer, beamFailureInstanceMaxCount, OR Reference signals used for beam failure detection is reconfigured by upper layers associated with this Serving Cell).
Yuki and Liina are both considered to be analogous to the claimed invention because they are in the same field of wireless communication. Therefore, it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to combine the system of Yuki and the features of setting BFI_counter to 0 to stop beamFailureRecoveryTimer based on beamFailureDetectionTimer, beamFailureInstanceMaxCount as taught by Liina, which is well known in the Field (paragraph [0021]).
Claim 13: The combination of Yuki and Liina teaches The apparatus according to claim 12, wherein, if the medium access control control element signaling can update or reconfigure any reference signal for beam failure detection in a beam failure detection reference signal set of a serving cell (Yuki, Fig. 2, 3, 4, 5, [0226], Two TCI states in the CORESET are updated by the MAC CE, and thus the UE updating a BFD-RS/RLM-RS explicitly or implicitly so that the BFD-RS/RLM-RS includes an RS in both of the two TCI states for the CORESET ), the processor circuitry enables the MAC entity to set the counter of the beam failure instance of the beam failure detection reference signal set to be 0 (Liina, [0021], table 4, disclose setting BFI_COUNTER to 0 if the Serving Cell is SCell, and a PDCCH addressed to C-RNTI indicating uplink grant for a new transmission is received Truncated BFR MAC CE which contains beam failure recovery information of this Serving Cell, [0068-0069], the mapping of BFD RS to per TRP follows the TCI state mapping a UE has received by MAC CE, when the MAC CE indicates certain TCI states to be mapped to certain TRPs for PDSCH reception, the UE uses these same reference signals as BFD resources, MAC CE may change the resource to be monitored per TRP for BFD).
The motivation for combining Yuki and Liina regarding to the claim 12 is also applied to claim 13.
Claim 14: The combination of Yuki and Liina teaches The apparatus according to claim 12, Liina further teaches wherein, if a higher layer reconfigures beamFailureDetectionTimer, beamFailureInstanceMaxCount (alternative) or any reference signal for beam failure detection of a beam failure detection reference signal set of a serving cell, or the medium access control control element signaling updates or reconfigures any reference signal for beam failure detection in the beam failure detection reference signal set of the serving cell, the processor circuitry enables the MAC entity to set the counter of the beam failure instance of the beam failure detection reference signal set to be 0 ([0021], table 4, disclose setting BFI_COUNTER to 0 based on eamFailureDetectionTimer, beamFailureInstanceMaxCount, or any of reference signals used for beam failure detection is reconfigured by upper layers associated with this Serving Cell).
The motivation for combining Yuki and Liina regarding to the claim 12 is also applied to claim14.

Claim 11: Yuki does not explicitly teach the apparatus according to claim 10, wherein, a value of the field being 1 indicates that the next octet is the same set of BFD-RS information as the BFD-RS information of the current octet.
Zhu, from the same or similar field of endeavor, teaches a value of the field being 1 indicates that the next octet is the same set of BFD-RS information as the BFD-RS information of the current octet ([0353], If a bit position in the second MAC CE command/bitmap configuring/indicating the entity ID is set to “1”, the corresponding BFD RS in the BFD RS beam set associated with the indicated entity ID could be replaced/updated by a RS index, which is activated/selected by the first MAC CE activation command that indicating the entity ID, or from the list/set/pool of QCL source RS indexes).
Yuki and Zhu are both considered to be analogous to the claimed invention because they are in the same field of wireless communication. Therefore, it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to combine the system of Yuki and the features of using a value of the field to indicate that the next octet is the same set of BFD-RS information as the BFD-RS information of the current octet as taught by Zhu, for the benefit for reducing BFD-RS configuration overhead, by using entity ID associated with one or more BFD RSs (paragraph [0386-388]).

Wherein entity ID is serving the similar as “a group of released second reference signal identifiers”).
Yuki and Zhu are both considered to be analogous to the claimed invention because they are in the same field of wireless communication.
