Otherwise, a UE may try to perform SL communication with its peer UE. Each UE may maintain its SL DRX configuration which may include a transmission pattern and/or a reception pattern that the UE expects to perform transmission and/or reception to a peer UE, and exchange the SL DRX configuration with the peer UE. Based on the exchange of the SL DRX configuration, the UE may determine when to perform transmission or reception to or from the peer UE during an SL DRX operation.

3, Li and LIN provide the method of claim 2, further comprising: excluding, from the set of candidate time-frequency resources, an occupied resource with a sidelink reference signal receiving power S-RSRP greater than or equal to a threshold [Li par 0304, The second excluding step is that if the UE receives or detects a control signaling in a TTI m, the UE may exclude the candidate resources according to the received control signaling. For instance, the second excluding step is shown as Step 2-2 in FIG. 9. More specifically, if the UE receives or detects a control signaling scheduling a transmission in a TTI m and the measurement result of the scheduled transmission and/or the control signal is over a threshold, the UE may exclude the candidate resources according to the received control signaling. The measurement result may be Reference Signal Received Power (RSRP). More specifically, the measurement result may be PSSCH-RSRP];
wherein, the threshold is determined based on a lower limit of a number of candidate time-frequency resources to be retained in the set of candidate time-frequency resources[par 0192, table 2 For frequency range 1 and 2, if receiver diversity is in use by the UE, the reported PSCCH-RSRP value shall not be lower than the corresponding PSCCH-RSRP of any of the individual receiver branches]

It may mean that for selecting the first sidelink resource, the first device may exclude candidate sidelink resources in slots out of the (assumed or expected) (sidelink) active or wake-up time of the second device. For selecting the first sidelink resource, the first device may exclude candidate sidelink resources in slots comprised in the (assumed or expected) (sidelink) non-active or sleep time of the second device].

For example, a Tx UE may consider future transmission resource close to the latest new transmission (e.g., the duration to determine whether it is close enough can be determined by a timer or a configured time gap) as high-priority transmission resource],
configured to indicate that the receiving-end user equipment is in a state of receiving at least one of a sidelink control channel or a sidelink shared channel during a time period corresponding to the future time-frequency resource [par 0162, if the peer UE is a SL DRX capable UE as well, or if the interested groupcast/broadcast service is operating SL DRX, a SL DRX capable UE does not uses the shared resource pool for sidelink communication. In other words, a SL DRX capable UE may use the shared resource pool only when it wants to deactivate SL DRX operation to coexist with peer UE not supporting SL DRX or to support a groupcast/broadcast service not operating in SL DRX mode. If the SL DRX capable UE wants to perform SL DRX for its sidelink communication, it uses other resource pools dedicated for SL DRX operation].

Response to Arguments
Moreover, the amended claim does not merely add a step of "sending control information carrying the DRX setting to the receiving-end UE", but establishes a clear technical correlation chain: selecting a DRX setting from a plurality of DRX settings and sending the selected DRX setting to the receiving-end UE the receiving-end UE adopts the received DRX setting the sending-end UE schedules the resources for the first K repetitions based on the same DRX setting. That is, the same DRX setting-obtained by the sending-end UE (including via control information) and adopted by the receiving-end UE-is the direct basis for determining the time-frequency transmission resource, including those used for the first K repetitions. The "sending" step and the "determining" step are not independent operations; rather, they are integrally linked: the sending-end UE sends a selected DRX setting to the receiving-end UE to synchronize DRX behavior, and then relies on that same DRX setting to perform resource selection. Li teaches nothing about the above technical correlation chain. Therefore, Li fails to disclose the above technical features of claim 1.
The Examiner's reliance on LIN paragraph 0063, which states that "the transmitter UE determines when the receiver UE should keep awake to monitor SCI", does not cure the deficiency of Li. Determining when a receiver should be awake is not the same as selecting a DRX setting from multiple DRX settings, sending it via control information to indicate the receiving-end UE to adopt it, and using that same setting for resource selection. LIN's DRX coordination is about exchanging configurations so that both sides know when to wake up; it does not teach the active, rule-based selection and indication of the selected DRX setting recited in amended claim 1. In summary, Li, Lin, or their combination do not teach or suggest the above integrated technical chain recited in amended claim 1. Bao, Loehr, and Wu fail to remedy the deficiencies of Li and Lin, e.g., by failing to teach or suggest the above technical features of claim 1.
Accordingly, for at least the above reasons, Applicant respectfully requests reconsideration and withdrawal of the rejection of claim 1. Based on similar reasons, independent claims 13 and 22 are patentably distinct from the cited prior art. Reconsideration and withdrawal of the rejection of claims 13 and 22 is respectfully requested.
Claims 2-4, 6-12, and 14-19 depend from one of claims 1 and 13, argued above as being patentably distinct from the cited art, and therefore benefit from like arguments of patentability. Accordingly, Applicant respectfully requests reconsideration and withdrawal of the rejection of claims 2-4, 6-12, and 14-19.
The examiner respectfully disagrees Lin discloses the applicant’s amended limitations Lin disclose wherein the method further comprises: sending control information carrying the DRX setting to the receiving-end UE [par 0060, 0061, 0067, To enable discontinuous SCI monitoring while ensuring normal SL communication, a UE needs to know when to communicate with its peer UE, i.e., to know if its peer UE is in active time. Otherwise, a UE may try to perform SL communication with its peer UE. Each UE may maintain its SL DRX configuration which may include a transmission pattern and/or a reception pattern that the UE expects to perform transmission and/or reception to a peer UE, and exchange the SL DRX configuration with the peer UE. Based on the exchange of the SL DRX configuration, the UE may determine when to perform transmission or reception to or from the peer UE during an SL DRX operation. In addition to the SL DRX configuration (with transmission pattern and/or reception pattern), a Rx UE may further determine an additional and/or aperiodic DRX-ON duration or SL active time according to the resource reservation in the SCI received from the Tx UE], the paragraphs show
UE expects to perform transmission and/or reception to a peer UE, and exchange the SL DRX configuration with the peer UE, wherein the receiver UE an additional and/or aperiodic DRX-ON duration or SL active time received in the SCI from the transmitting UE.
Paragraph 0075 of LIN show wherein the DRX setting carried by the control information is selected from a plurality of DRX settings[par 0075, UE may select one SL DRX configuration to satisfy QoS requirement of all QoS flows, SL radio bearers, or QoS profiles, or to support the highest priority or the most latency stringent QoS flow, SLRB, or QoS profile], the paragraph show the UE selects a DRX configuration according to quality of service.
In paragraph 0079 of LIN is shows the control information indicates the receiving-end UE to adopt the DRX setting carried by the control information [par 0079, Upon receiving the message indicating SL DRX configuration change, the Rx UE accordingly switches its SL DRX configuration to align with Tx UE's selection of SL DRX configuration]; the paragraph shows the reception aligning with the transmitter DRX selection.
The paragraphs of Lin show and wherein the DRX setting carried by the control information is the DRX setting based on which the time-frequency transmission resource is determined [par 0064, 0098, The reception pattern may include information indicative of specific time-frequency radio resources that the UE uses to perform reception form the peer UE. For example, the information may include a timing offset for SL DRX (also called an SL DRX offset, including an SL DRX start offset and/or an SL DRX slot offset), a transmission pattern per repetition cycle (e.g., specified by a duration for transmission located in the beginning of each repetition cycle) (also called an SL DRX-ON duration), and a repetition cycle length (also called an SL DRX cycle). Each UE may be mandated to monitor a specific set of time-frequency radio resources for reception of possible ping/discovery message from peer UEs. The time-frequency radio resources to be monitored by default can be a specific resource pool (e.g., a default resource pool), or a specific bandwidth part (e.g., a default SL bandwidth part), or a specific time duration per cycle (e.g., a default DRX reception pattern for a UE to monitor)], the paragraphs show time-frequency radio resources can be a specific time duration per cycle (e.g., a default DRX reception pattern for a UE.
