In some aspects, the plurality of second beam measurement signals can include beam sweeping SCI-2 and a DMRS. In some aspects, the plurality of second beam measurement signals can include CSI-RSs. In aspects, the UE 302a may transmit a trigger to trigger the UE 302b to perform a receive beam selection. The trigger can be an instruction in SCI-2 and/or a CSI-RS trigger.”: [0166]).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teaching of TSAI to include the above recited limitations as taught by LIU.

While TSAI teaches, “discovering a transmitting UE during a discovery duration” ;
TSAI does not expressively disclose:
based on having data to receive from the transmitting UE, using the at least one transceiver.
LIU, in the same field of endeavor, discloses:
based on having data to receive from the transmitting UE, using the at least one transceiver (see fig. 3 where UE 302A and UE 302B are in Sideline communication: UE 302A transmits data during Data duration 335 in fig. 3: “one or more sidelink channels 310 may include a PSCCH 315, a PSSCH 320, and/or a PSFCH 325”; “ the PSCCH 315 may carry SCI 330, which may indicate various control information used for sidelink communications, such as one or more resources (e.g., time resources, frequency resources, spatial resources, and/or the like) where a transport block (TB) 335 (==DATA DURATION) may be carried on the PSSCH 320. The TB 335 may include data.”: : [0085]).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teaching of TSAI to include the above recited limitations as taught by LIU. The suggestion/motivation would be to provide intra-slot transmit beam selection and receive beam selection for sidelink to cover V2X communications over licensed bands and unlicensed bands.: (LIU: [0002]-[0005]).
With respect to dependence claim:
Regarding claim 2, TSAI in view of LIU teaches the invention of claim 1 as set forth above. Further, TSAI teaches, The method of claim 1, wherein the BRS is transmitted aperiodically ( “ aperiodic transmission property on sidelink (SL) communication.”: [0057]; “ UE assesses the radio link quality only according to aperiodic SL-CSI-RS resource configurations that are quasi co-located with the SL-DMRS for PSCCH receptions monitored by the UE”: [0117], [0120]).
Regarding claim 3, TSAI in view of LIU teaches the invention of claim 1 as set forth above. Further, TSAI teaches, The method of claim 1, wherein the method further comprises, during the discovery duration:
transmitting a discovery signal to the receiving UE (see fig. 13: Discovery announcement includes Discovery Signal : “ Link recovery procedures on SL: To establish a unicast connection on sidelink, the discovery announcement procedure which a UE (e.g., source UE) may transmit the discovery message, e.g., “I am here.”, or “who is there?” via PSSCH or dedicated physical sidelink discovery channel to neighbor or vicinity UE(s) should be completed.”: [0056]); and
receiving a response message to the discovery signal from the receiving UE (response from Discovery message for link establishment : [0056]).
Regarding claim 4, TSAI in view of LIU teaches the invention of claim 3 as set forth above. Further, TSAI teaches, The method of claim 3, wherein, based on the receiving UE detecting a plurality of transmission beams by receiving the discovery signal, i) the response message includes an index and a measurement result of a beam having a best measurement result among the plurality of transmission beams, and ii) the response message is received using a resource corresponding to the beam having the best measurement result ( “ Beam Failure Recovery (BFR) or link recovery procedure may involve the following steps: e.g., Beam Failure Detection (BFD), Candidate Beam Identification (CBI), Beam Failure Request (BFRQ), and Beam Recovery Response (BFR) from network. However, on SL communication, NR Uu BFR procedure may not be suitable for SL BFR. For instance, on SL, there may be no periodical beamformed reference signal like CSI-RS or SS will be guaranteed to be transmitted because aperiodic transmission property on SL communication. In addition, the receive UE may leave or be away from the transmit UE after a certain period. Those cases could result in no SL data transmission in a reporting or monitoring period for beam or link monitoring on sidelink. In this scenario, UE may decide whether there is a need to maintain the link or not on SL communication. In other word, if the transmit UE has nothing to transmit or due to data traffic congestion in a reporting or monitoring period, equivalently, there may be no reception data at the receive UE. In this case, the receive UE may not perform BFD, find the candidate beams, and trigger beam failure request (BFRQ). Therefore, link recovery procedure on SL should consider when there is nothing to measure and thus to report or indicate to the higher layer by an RX UE.”: [0057]-[0059]; [0062]-[0065]).
Regarding claim 5, TSAI in view of LIU teaches the invention of claim 3 as set forth above. Further, TSAI teaches, The method of claim 3, wherein, based on the receiving UE detecting a plurality of transmission beams by receiving the discovery signal, i) the response message includes an index and a measurement result for each of the plurality of transmission beams, and ii) the response message is received using a resource associated with each of the plurality of transmission beams (“ SL-CSI-RS channel quality can be used for determination whether there is a beam failure occurring or not. RX UE may measure the received SL-CSI-RS and report the metric (e.g. L1-RSRP/RSRQ, SINR, or hypothetical BLER) to TX UE. The feedback of SL-CSI-RS reporting may use PSFCH or PSCCH and PSSCH. When TX UE receive the channel quality report then TX UE may decide whether there is a beam failure that should be reported to a higher layer for indicating this link (e.g., link i) failure or not. In mode 2, if feedback reporting uses sidelink control channel (e.g. PSCCH) and data channel (e.g. PSSCH) for RX UE, then the feedback resource for RX UE can be based on the following approaches: (1) RX UE may reserve or select a resource via channel sensing, or (2) TX UE can reserve a resource in advance for RX UE transmitting the feedback. If the feedback channel is based on a dedicated SL data channel e.g., PFSCH then TX UE may reserve a resource for RX UE in advance for RX UE transmitting the feedback. For SL mode 1, network may reserve a resource in advance for RX UE. SL-CSI-RS quality can be analog to monitor PSCCH quality when SL-CSI-RS is QCLed with RX UE PSCCH. If TX UE cannot detect the RX UE SL-CSI-RS where there is an expected feedback from RX UE then TX UE may also count this sample into Ll-RSRP SINR/RSRQ, or hypothetical BLER calculation.”: [0074]).
Regarding claim 6, , TSAI in view of LIU teaches the invention of claim 1 as set forth above. Further, TSAI teaches, The method of claim 1, wherein the response message is received via a preconfigured frequency resource, and
wherein the preconfigured frequency resource does not conflict with a frequency resource used by another UE for the response message during a discovery process ( “SL-CSI-RS channel quality can be used for determination whether there is a beam failure occurring or not. RX UE may measure the received SL-CSI-RS and report the metric (e.g. L1-RSRP/RSRQ, SINR, or hypothetical BLER) to TX UE. The feedback of SL-CSI-RS reporting may use PSFCH or PSCCH and PSSCH. When TX UE receive the channel quality report then TX UE may decide whether there is a beam failure that should be reported to a higher layer for indicating this link (e.g., link i) failure or not. In mode 2, if feedback reporting uses sidelink control channel (e.g. PSCCH) and data channel (e.g. PSSCH) for RX UE, then the feedback resource for RX UE can be based on the following approaches: (1) RX UE may reserve or select a resource via channel sensing, or (2) TX UE can reserve a resource in advance for RX UE transmitting the feedback. If the feedback channel is based on a dedicated SL data channel e.g., PFSCH then TX UE may reserve a resource for RX UE in advance for RX UE transmitting the feedback. For SL mode 1, network may reserve a resource in advance for RX UE. SL-CSI-RS quality can be analog to monitor PSCCH quality when SL-CSI-RS is QCLed with RX UE PSCCH. If TX UE cannot detect the RX UE SL-CSI-RS where there is an expected feedback from RX UE then TX UE may also count this sample into Ll-RSRP SINR/RSRQ, or hypothetical BLER calculation.”: [0074]; [0173]-[0185]).
Regarding claim 7, TSAI in view of LIU teaches the invention of claim 1 as set forth above. Further, TSAI teaches, The method of claim 1, wherein the response message comprises at least one of a response type, a UE Identifier (ID), and/or a status of the receiving UE (UE Identifier : [0084]; “ Once RX UE identifies a candidate SL-CSI-RS (e.g., ID=3 which corresponds to a specific beam) then RX UE may select the correspondent resource to transmit the BFRQ. Therefore, TX UE may perform the proper receiving beam for BFRQ reception.”: [0099]).
Regarding claim 8, TSAI in view of LIU teaches the invention of claim 1 as set forth above. Further, TSAI teaches, The method of claim 1, wherein the method further comprises receiving information informing presence or absence of an intention to transmit data from the receiving UE ( “ At step 271, UE 242 may determine a link failure. If no link failure, then proceed to step 267, but if there is a link failure proceed to step 272 (trigger BFRQ and start T2 timer). At step 264, UE 242 may send BFRQ. At step 265, in response to BFRQ of step 264, UE 242 may monitor PSCCH+PSSCH. At step 274, UE 242 determines whether data is received from UE 241. If data is received, then proceed to step 275 and if data is not received proceed to step 273 (monitor PSCCH+PSSCH). At step 275, if T2 is determined to have expired then proceed to step 267. If T2 is determined to he expired then proceed to step 272.”: [0097]).
Regarding claim 9, TSAI in view of LIU teaches the invention of claim 8 as set forth above. Further, TSAI teaches, The method of claim 8, wherein the information informing presence or absence of the intention to transmit data is received in conjunction with a Hybrid Automatic Repeat Request (HARQ)-Acknowledgment (ACK) for the data and/or is received subsequent to reception of the HARQ-ACK (“ In mode 1, RX UE may send a request to network for reserving the resource or use configured grant resource to transmit a beam sweeping burst with or without HARQ-ACK/NACK feedback resource. The detail of beam sweeping burst may refer to beam sweeping burst as associated with the above BFR performed at TX/source UE. If RX UE physical layer sends an indication(s) to higher layer upon successfully decoding a data from TX UE before the timer T.sub.1 expires, then RX UE may reset the timer T.sub.1 and physical layer continues with (re)transmission with TX UE because the radio link has recovered.”: [0104]; “ ] For example, HARQ-ACK/NACK only, BFRQ indication can be based on sequence based PSFCH. For SL CSI and HARQ-ACK/NACK +SL CSI, they can be based on UCI with DMRS based PSFCH.”: [0169]).
Regarding claim 10, TSAI in view of LIU teaches the invention of claim 9 as set forth above. Further, TSAI teaches, The method of claim 9, wherein, based on the information informing presence or absence of the intention to transmit data being received in conjunction with the HARQ-ACK, the information informing presence or absence of the intention to transmit data is received via a frequency resource associated with a frequency resource for the HARQ- ACK and/or via a dedicated frequency resource (“ Measurement with the SL-DMRS or Sequence of Feedback Channel PSFCH: TX UE may use the SL-DMRS of feedback channel (e.g., modulation based PSFCH) or the sequence of the feedback channel (e.g., sequence based PSFCH) for measurement when HARQ-ACK/NACK or SL-CSI-RS reporting are/is enabling. Disclosed herein, PSFCH may be used for the following purposes: [0162] HARQ-ACK/NACK only [0163] SL CSI only [0164] HARQ-ACK/NACK+SL CSI [0165] BFRQ indication
[0166] PSFCH may be designed by the following methods: [0167] Sequence based, in this case, HARQ-ACKNACK information is based on a sequence. The PSFCH may be occupied more than 2 symbols in a slot. If Zadoff-Chu sequence is used for this design. For example, the following may be defined as a sequence r.sub.u,v.sup.(α)(n)=e.sup.jαnr.sub.u,v.sup.(α)(n), where 0 <n <N is the length of PSFCH for HARQ-ACK/NACK sequence. HARQ-ACK/NACK information like {0, 1} or {00, 01, 10, 11} can be mapped to different (cyclic-shift) values of a for a root sequence which is derived by parameters u and v. [0168] UCI with SL-DMRS, in this case, UCI will use BPSK or QPSK for modulation order. The PSFCH may be occupied more than 2 symbols in a slot.
[0169] For example, HARQ-ACK/NACK only, BFRQ indication can be based on sequence based PSFCH. For SL CSI and HARQ-ACK/NACK +SL CSI, they can be based on UCI with DMRS based PSFCH.”: [0161]-[0169]).
Regarding claim 11, TSAI in view of LIU teaches the invention of claim 8 as set forth above. Further, TSAI teaches, The method of claim 8, wherein the information informing presence or absence of the intention to transmit data is received by being included in a response message to a discovery signal in the discovery duration ( “ With continued reference to FIG. 3, at step 253, a discovery announcement procedure may occur. The discovery announcement procedure may involve UE 241 and UE 242. Subsequent to the discovery announcement procedure, there may be a start of TX and start/reset of timer T1 at UE 241. At step 245, there is determination of whether T1 expired. If T1 expired then proceed to step 252, if T1 not expired then proceed to step 260. Step 260 may include sending PSCCH+PSSCH to UE 242 or receiving PSFCH ACK/NACK from UE 242. At step 246, UE 241 may determine a link failure. If no link failure, then proceed to step 245, but if there is a link failure proceed to step 247 (start timer T2). At step 248, UE 241 does TX beam sweeping burst. At step 259, there may be more sending PSCCH +PSSCH to UE 242 or receiving PSFCH ACK/NACK from UE 242. At step 249, UE 241 determines whether T2 expires, if so, then proceed to step 251. If T2 is not expired, then determine whether link recovered at step 250. If link is not recovered then proceed to step 251, if the link is recovered then proceed to step 245.”: [0079]).
Regarding claim 12, TSAI in view of LIU teaches the invention of claim 8 as set forth above. Further, TSAI teaches, The method of claim 8, wherein the information informing presence or absence of the intention to transmit data is received periodically ([0079], “ The indication of sidelink BFD, CBI, or BFRQ triggering mechanism is illustrated in FIG. 12A-12B. In each BFD/CBI report occasion, there is an associated monitoring window (or a periodical interval T.sub.1), if the monitored SL-RS's hypothetical BLER (e.g., SL-DMRS for PSCCH) is under a (pre-) configured threshold Q.sub.out,SL within the monitoring period, then the RX UE indicates BFD to the higher layer. In addition, upon request from higher layers, if there are SL-RS(s) being identified as candidate beams, e.g., when SL link quality (e.g., L1-RSRP, SIRN or hypothetical BLER) is greater or better than a (pre-) configured Q.sub.in,SL then the candidate SL-RS(s) can be reported to higher layer. Otherwise, if no BFD is detected within the associated monitoring window/period T.sub.1, then RX UE may designate no BFD report to the higher layer. Hence, periodic indications of beam failure may be provided based on operation of the timer T.sub.1, e.g. if TX UE reset timer T.sub.1 after it expires then the link may be periodically monitored by UE. Note: periodically monitoring a link doesn't mean RX UE will expect periodically receiving data packet for this link. UE procedure for BFR performed at RX UE side is summarized in FIG. 13.”: [0096]; [0053]).
Regarding claim 13, TSAI in view of LIU teaches the invention of claim 1 as set forth above. Further, TSAI teaches The method of claim 1, wherein the transmitting UE is in communication with at least one of a mobile device, a network, and/or autonomous vehicles other than the transmitting UE (see fig. 13; UE can be in V2V, V2I, V2N V2P : [0191]).
