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 1-3, 6-13, and 16-20 are rejected under 35 U.S.C. 103 as being unpatentable over Spreadtrum Communications, "Discussion on Relay Discovery and (re)selection for U2U Relay", R2-2207686, 3GPP TSG-RAN WG2 Meeting #119 electronic August 17-29, 2022, 8 pages (hereafter “Spreadtrum”) in view of WO 2024015361 A1 (hereafter “Kini”).
Regarding claim 1, A method performed by a first user equipment (UE) in a wireless communication system, the method comprising: obtaining configuration information used for identifying, by the first UE performing a UE-to-UE (U2U) relay operation, whether to perform transmission of a second message based on a first message received by the first UE from a second UE;
Spreadtrum, page 2, Proposal 3: RAN2 confirm that the shared and dedicated discovery pools in R17
are reused to Transmit/receive discovery messages for UE-to-UE relay and all agreements made for
discovery pool are applicable to UE-to-UE relay discovery. Another issue is which configuration is used
for UE-to-UE relay discovery. ln R17, UE decides the discovery configuration it should follow by
adopting the following rules:
L2 relay UE (first UE) will always use the discovery configuration provided by gNB (either via SIB or
dedicated Signalling = obtaining configuration information)
Note: claim 6 explain obtaining the configuration information including the information on the
threshold comprises as “receiving, from a base station, a system information block (SIB) including
information on threshold” Thus, UE obtains the configuration information via the discovery
configuration provided via SIB.
Spreadtrum, page 5, [0007] ; On reception of Solicitation message (first message= first discovery= first
Solicitation= First message from the second UE= Spreadtrum, Fig. b, Step 1), the candidate Relay UE
broadcasts Solicitation message (second message= second

and performing, transmission of the second message based on the received first discovery message.
In Model B described in sol#18, as depicted in Figure b), Source UE broadcasts Solicitation message (First discovery message) indicating that it wants to communicate with Target UE via a relay. On reception of Solicitation message (based on the received first discovery message), the candidate Relay UE broadcasts Solicitation message (second message) with RSC (relay source code) or target UE ID. The Target UE that matches the RSC or the UE JD responds to the candidate Relay UE with a Response message. Finally, the candidate Relay UE send Response message to the Source UE on reception of response message from the Target UE.
Although Spreadtrum teaches whether to perform transmission based on threshold, Spreadtrum does not teach the threshold is a reference signal received power (RSRP) threshold, and identifying based on RSRP measured whether to perform transmission of the second message based on the received first discovery.
Kini teaches obtaining information on RSRP threshold.
Kini [0096]; The U2N Relay WTRU can perform Relay discovery message transmission and/or may monitor the sidelink for a Relay discovery message while in RRCJDLE, RRCJNACTIVE or RRC_CONNECTED. The network may broadcast an RSRP threshold (e.g., maximum Uu RSRP threshold, a minimum Uu RSRP threshold, or both), for example, which may be used by the U2N Relay WTRU (e.g., to determine if it can transmit Relay discovery messages to U2N Remote WTRU(s)).
identifying, based on reference signal received power (RSRP) measured whether to perform transmission of the second message based on the received first discovery.
Kini [0125] A WTRU may determine (e.g., select) a relay selection behavior to perform, for example, based on determining whether to perform a discovery procedure (e.g., transmission and/or reception of discovery) and/or the discovery resource pool to use. A (e.g., relay) WTRU may decide to transmit and/or forward the discovery message (forward the discovery message= transmission of the second message), for example, if the SL-RSRP or SD-RSRP is above a certain threshold (identifying based on RSRP and threshold= result of identification). A WTRU configured with both dedicated and shared resource pools may choose to use a dedicated pool for data with a high QoS value, for example, whereas lower QoS data may result in use of a shared resource pool for discovery messages. A WTRU may utilize information tied to a received discovery message (received discovery message= communication with the second UE), for example, to determine whether to forward a discovery message (to transmit the second message). This may be information such as the resource pool that the message was received on, the number of sub-channels occupied by discovery message, CBR of the resource pool, RSRP of received discovery message (RSRP measurement based on communication with the second UE), hop count of discovery message (e.g., if available), hop count to target WTRU (e.g., if available), potential likelihood of success that this can be a successful relay between source (second UE)/remote and target WTRUs (e.g., which may be based on number WTRUs this relay WTRU is currently serving, load of the relay, SL- RSRP/SD-RSRP levels to neighboring WTRUs based on some historical context, etc.), and/or the like ( result of identifying threshold and RSRP = result of identification).
In view of Kini , Spreadtrum is modified such that the second discovery message (second message) is transmitted from the relay UE based on the threshold of RSRP.
Spreadtrum and Kini are analogous art to the claimed invention because they are in the
same field of endeavor, transmission of discovery message in the relay communication systems.
It would be obvious before the effective filing date of claimed invention, to a person ordinary skill in the
art to modify Spreadtrum in a manner described above to substitute the known technique of measuring
link quality and meeting a threshold (discussed in Spreadtrum) with the measuring RSRP to determine
whether to send the second message based on meeting and RSRP threshold technique in Kini with the
predictable results in order to adopt a relay behavior or triggering discovery procedure (Kini [0004]).

Spreadtrum, page 5, [0007] ; In Model B described in sol#8, as depicted in Figure b), Source UE (second
UE) broadcasts Solicitation message indicating that it wants to communicate with Target UE (third
UE) via a relay (First UE). On reception of Solicitation message (first message= first discovery= first
solicitation), the candidate Relay UE broadcasts Solicitation message (second message= second
discovery (second message) with RSC (relay source code) or target UE ID.

adopting the following rules:
L2 relay UE will always use the discovery configuration provided by gNB (either via SIB or dedicated
Signalling).

or in case that the first UE is in a radio resource control (RRC) connected state, receiving, from the base station, an RRC message including the information on the threshold.

Regarding claim 7, Spreadtrum in view of Kini teaches all limitation of claim 1 as discussed above. Spreadtrum does nor teach the RSRP includes at least one of sidelink discovery- reference signal received power (SD-RSRP) or sidelink (SL)-RSRP.
Kini teaches the RSRP includes at least one of sidelink discovery- reference signal received power (SD-RSRP) or sidelink (SL)-RSRP.

Regarding claim 15, The first UE of claim 14, wherein, wherein, the second discovery message is forwarded between the first and the third UE for the U2U relay operation.
Spreadtrum, page 5, [0007] ; On reception of Solicitation message (first message= first discovery= first
solicitation), the candidate Relay UE broadcasts Solicitation message (second message= second
discovery based on first message) with RSC (relay source code) or target UE ID.
Spreadtrum in view of Kini does not teach in case that a link for the U2U relay operation is pre-established between the first UE and the third UE, the discovery message is forwarded by using a message based on the link, pre-established between the first UE and third UE.
Cheng teaches in case that a link for the U2U relay operation is pre-established between the first UE and the third UE,
Cheng, Fig. 3 [0042]; The R-UE 110-2 (relay UE) can operate to provide its UE to UE relay capability and register accordingly with the network. The authorization and the parameter provisioning can be performed and the U2U relay including the S-UE 110-1 and D-UE 310-3 can be provisioned with relay policy parameters. At least one D-UE 310-3 (destination UE) can determine the destination Layer-2 (L2) ID for signaling reception for PC5 unicast link establishment via the second channel link 304, for example. The destination Layer-2 ID is configured with the D-UE 310-3. (a link for the U2U relay operation is pre-established between the first UE and the third UE)
the discovery message is forwarded by using a message based on the link, pre-established between the first UE and third UE.
Cheng, Fig. 3, [0043], Step 314; The ProSe layer can trigger the peer UE discovery mechanism by sending an end to end (E2E) broadcast direct communication request (BCAST) message 312.
Cheng, Fig. 3, [0044]; The R-UE 110-2 receives the BCAST message 312 and verifies if it is configured to relay this application (i.e., R-UE 110-2 compares the announce ProSe Application ID with its provisioned relay policy/parameters, The R-UE 110-2 forwards the E2E broadcast direct communication request message, BCAST 314, by using its own Layer-2 ID as Source L2 ID, and additionally includes the R-UE's ID in the message with info identifying the S-UE 110-1. The R-UE 110-2 can handle this E2E broadcast message in the ProSe layer, and forwards any subsequent E2E PC5-S message based on adaptation layer information ( forwarded by using a message based on the link, pre-established between the first UE and third UE.)The D-UE 310-3 can then receive the direct communication request message via the U2U relay (with adaptation layer info). [0044] The R-UE 110-2 receives the BCAST message 312 and verifies if it is configured to relay this application (i.e., R-UE 110-2 compares the announce ProSe Application ID with its provisioned relay policy/parameters, The R-UE 110-2 forwards the E2E broadcast direct communication request message, BCAST 314, by using its own Layer-2 ID as Source L2 ID, and additionally includes the R-UE's ID in the message with info identifying the S-UE 110-1. The R-UE 110-2 can handle this E2E broadcast message in the ProSe layer, and forwards any subsequent E2E PC5-S message based on adaptation layer information. The D-UE 310-3 can then receive the direct communication request message via the U2U relay (with adaptation layer info).
Note: Cheng [0041]; If the UE intends to broadcast a direct communication request or a solicitation message, it indicates in the message whether a U2U relay could be used. (broadcast message= solicitation= discovery message)
In view of Cheng , Spreadtrum in view of Kini is modified such that the discovery message is forwarded when the link is established between relay UE and the destination (Target) UE.
Spreadtrum and Cheng are analogous art to the claimed invention because they are in the
same field of endeavor, transmission of discovery message in the relay communication systems.
It would be obvious before the effective filing date of claimed invention, to a person ordinary skill in the
art to modify Spreadtrum in view of Kini in a manner described above to forward the discovery message
to the target UE based on pre-established PC5 link configuration to allow the direct communication
between UEs over a direct channel and forward the information of the UEs based on the link established
between the relay and target UE (Cheng [0017).
