[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first" and "second" are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0033] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA) and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the technology described can be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies. However, the following description describes a New Radio (NR) system for illustrative purposes, and the NR terminology is used in most of the following description, although these technologies can also be applied to applications other than NR system applications, such as 6th generation (6G) systems. th Generation, 6G) communication system.

[0034] In the embodiment of the present application, the terminal may also be referred to as a terminal device or user equipment (UE). The terminal may be a mobile phone, a tablet personal computer, a laptop computer or a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE) and other terminal-side devices. Wearable devices include: bracelets, headphones, glasses, etc.

[0035] To better understand the solution provided by this application, the following contents are first described:

[0036] 1. Introduction to Sidelink (SL)

[0037] like Figure 1a As shown, the Long Term Evolution (LTE) system supports a sidelink (or translated as a side link, side link, etc.) for direct data transmission between end user equipment (UE) without going through network equipment.

[0038] LTE sidelink is designed for specific public safety applications (such as emergency communications at disaster sites like fires and earthquakes) and vehicle-to-everything (V2X) communications. V2X communications encompass a wide range of services, including basic safety-related communications, advanced (autonomous) driving, platooning, and sensor expansion. Because LTE sidelink only supports broadcast communications, it is primarily used for basic safety-related communications. Advanced V2X services with strict Quality of Service (QoS) requirements in terms of latency and reliability will be supported via 5G NR sidelink.

[0039] Sidelink transmission mode

[0040] Current sidelink transmissions are mainly categorized into broadcast, groupcast, and unicast. Unicast, as the name implies, is one-to-one transmission. Multicast is one-to-many transmission. Broadcast is also one-to-many transmission, but broadcasts do not guarantee that UEs belong to the same group.

[0041] Currently, sidelink unicast and multicast communications support the physical layer Hybrid Automatic Repeat reQuest (HARQ) feedback mechanism.

[0042] Sidelink Resource Allocation Modes: Mode 1 and Mode 2

[0043] The resource allocation modes of sidelink UEs are divided into two categories:

[0044] 1) Base station scheduling mode (mode 1): The base station (BS) schedules SL resource(s) to be used by the UE for SL transmission(s). That is, the network-side device (base station) controls and allocates resources to each UE.

[0045] 2) UE autonomous mode (mode 2): UE determines (i.e., BS does not schedule, SL transmission resource(s) within SL resources configured by BS / network or pre-configured SL resources), that is, each UE independently selects resources.

[0046] 2. Introduction to Uu Air Interface DRX (Uu DRX for short)

[0047] Both LTE and NR have introduced the DRX mechanism, which can save UE power by configuring the DRX start (DRX on) and DRX shutdown (DRX off) time. Figure 1b As shown, the on duration is a DRX on interval. If there is no scheduling, the UE will enter a DRX cycle off period after the on duration.

[0048] When configuring DRX, parameters such as onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimer, and longDRX-CycleStartOffset will be configured.

[0049] After DRX is configured, if the decoding of sent or received data fails, the UE needs to enter the active time to monitor the control channel and wait for retransmission scheduled by the network.

[0050] During the On Duration period, if a UE is scheduled and receives data in a certain slot, it is likely to be scheduled again in the following slots. Therefore, each time a UE is scheduled to transmit data for the first time, the drx-InactivityTimer timer is started or restarted. The UE will remain in the active state until the timer expires.

[0051] For downlink data reception, after receiving the downlink data transmission indicated by the PDCCH and feeding back the HARQ information, the UE will start the downlink return timer (HARQ RTT (Round Trip Time) Timer) for the corresponding HARQ process. If the HARQ RTT Timer times out and the data of the HARQ process is not successfully decoded, the UE will start the retransmission timer (drx-RetransmissionTimer) and monitor the PDCCH, waiting for transmission.

[0052] For uplink data transmission, the UE will start the uplink return timer (HARQ RTT Timer) for the corresponding HARQ process after receiving the PDCCH indicating uplink data transmission. After the HARQ RTT Timer expires, the UE starts the retransmission timer (drx-ULRetransmissionTimer) and enters the active state to monitor the PDCCH, waiting for the transmission scheduled by the network.

[0053] 3. SL CSI Report Introduction

[0054] like Figure 1c As shown, the process includes:

[0055] (1) The transmitter (TX UE) configures the SL CSI-RS reference signal and the upper limit of the SL CSI report delay to the receiver (RX UE) through PC5 Radio Resource Control (RRC) signaling.

[0056] (2) The TX UE sends data to the RX UE (along with the PSSCH). Data transmission is always accompanied by the transmission of the SL CSI-RS reference signal. At the same time, the RX UE measures the received SL CSI-RS reference signal.

[0057] (3) The TX UE triggers the RX UE's SL CSI report through the sidelink control information (SL SCI), and the RX UE starts the SL CSI report timer (the timer duration is the delay upper limit requirement in step (1)).

[0058] (4) During the running of the SL CSI report timer, the RX UE sends the SL CSI report to the TX. If the SL CSI report timer expires, the triggered SL CSI report is canceled.

[0059] The following describes in detail the method for establishing a connection provided by the embodiment of the present application through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0060] See also Figure 2 , an embodiment of the present application provides a method for processing an SL CSI report, the method being executed by a terminal, the method comprising:

[0061] Step 201: When the terminal is a receiving end, it receives SL SCI from the opposite terminal. The SL SCI is used to trigger the terminal's SLCSI report.

[0062] The above-mentioned opposite terminal is an opposite device that performs SL communication with the terminal, such as UE1 and UE2 that perform SL communication, wherein UE1 and UE2 can both act as transmitters or receivers, that is, the SL communication between UE1 and UE2 includes two directions, one direction is UE1 as the transmitter and UE2 as the receiver, and the other direction is UE1 as the receiver and UE2 as the transmitter.

[0063] Specifically, in the embodiment of the present application, when the terminal is the receiving end, the opposite terminal triggers the SL CSI report of the receiving end by sending SL SCI. Figure 1c The process in .

[0064] Step 202: Start the SL CSI reporting timer according to the SL SCI;

[0065] When the receiving end receives the SL SCI, it starts the SL CSI reporting timer.

[0066] Step 203: When the preset conditions are met, executing the processing operation corresponding to the preset conditions;

[0067] In an embodiment of the present application, the receiving terminal satisfies the preset conditions to perform processing operations corresponding to the preset conditions, thereby implementing some newly defined SL CSI reporting and SR cancellation and / or sending mechanisms under SL DRX.

[0068] When the terminal is a receiving end, the DRX parameter configuration of the terminal is a first DRX parameter configuration; when the terminal is a transmitting end (in this case, the opposite terminal is the receiving end), the DRX parameter configuration of the opposite terminal is a second DRX parameter configuration. The first DRX parameter configuration is different from the second DRX parameter configuration, that is, in both directions of SL communication, the DRX parameter configurations of the terminal and the opposite terminal are independent of each other. Alternatively, the first DRX parameter configuration and the second DRX parameter configuration are both common DRX parameter configurations, that is, in both directions of SL communication, the DRX parameter configurations of the terminal and the opposite terminal are shared.

[0069] It can be understood that before executing the above step 201, the terminal and the opposite terminal have already obtained their respective DRX parameter configurations.

[0070] The above-mentioned DRX parameter configuration may include parameters such as onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimer, and longDRX-CycleStartOffset. The embodiment of the present application does not limit the specific content of the DRX parameter configuration.

[0071] In an embodiment of the present application, when the transmitting end triggers the SL CSI report of the receiving end through SL SCI, the corresponding processing operation is performed based on the preset conditions that are met, so as to further stipulate the sending of the SL CSI report under the SL DRX mechanism, thereby reducing the sending of unnecessary SL CSI reports and saving SL wireless resources.

[0072] In some embodiments, satisfying the preset condition includes: satisfying any one of the first condition, the second condition, and the third condition;

[0073] First condition: The SL CSI reporting timer duration crosses the DRX on or DRX off boundary of the current DRX cycle, or crosses the DRX active time or DRX inactive time boundary of the current DRX cycle;

[0074] Specifically, the first condition is that the duration of the SL CSI report timer is greater than or equal to the duration of discontinuous reception starting DRX on in the current DRX cycle, and the duration of the SL CSI report timer is less than or equal to the duration of the current DRX cycle;

[0075] Or the first condition is that the duration of the SL CSI report timer is greater than or equal to the duration of the discontinuous reception activation time (DRX active time) of the current DRX cycle, and the duration of the SL CSI report timer is less than or equal to the duration of the current DRX cycle;

[0076] Second condition: The SL CSI reporting timer duration includes the DRX on or DRX active time of the next DRX cycle.

[0077] Specifically, the second condition is that the duration of the SL CSI report timer is greater than the duration of the current DRX cycle and includes at least part of the DRX on duration of the next DRX cycle;

[0078] Or the second condition is that the duration of the SL CSI reporting timer is greater than the duration of the current DRX cycle and includes at least part of the duration of the DRX active time of the next DRX cycle;

[0079] Third condition: SL CSI reporting behavior during DRX off or DRX inactive time configured by the network side or pre-configured by the terminal.

[0080] Specifically, 1 bit may be used to indicate the SL CSI reporting behavior, which is to allow continued sending of SL CSI reports during DRX off or DRX inactive time, or to not allow continued sending of SL CSI reports during DRX off or DRX inactive time.

[0081] In some implementations, for a scenario where the first DRX parameter configuration and the second DRX parameter configuration are different, when a preset condition is met, performing a processing operation corresponding to the preset condition includes at least one of the following:

[0082] 1. Satisfy the first condition:

[0083] (1) If the sending resource of the SL CSI report falls into the DRX off or inactive time, the triggered SL CSI report is canceled.

[0085] (2) If the SR resource triggered by the SL CSI report falls into the DRX off or inactive time, the triggered SR is canceled.

[0086] Specifically, when the first condition is met, if the time domain of the scheduling request SR resource triggered by the SL CSI report is during the DRX off or DRX inactive time, the triggered SR is canceled;

[0087] 2. Satisfy the second condition:

[0088] (1) If the sending resource of the SL CSI report falls into the DRX off or inactive time, the SL CSI report is still sent.

[0089] Specifically, when the second condition is met, if the time domain of the sending resource of the SL CSI report is during DRX off or DRX inactive time, the SL CSI report is sent to the opposite terminal; it should be noted that the resource allocation mode of the sidelink UE to which this processing operation can be applied is the base station scheduling mode (hereinafter referred to as mode 1) and the UE autonomous mode (hereinafter referred to as mode 2).

[0090] (2) Report the delay requirement or current remaining delay requirement of the SL CSI report to the base station.

[0091] Specifically, when the second condition is met, the latency requirement information or the current remaining latency requirement information reported by the SL CSI is sent to the network side. Considering the need to send latency assistance information before the base station actually allocates resources, or when the allocated resources are found to be inappropriate, so that the base station can allocate appropriate resources. It should be noted that this processing operation can also be applied to mode 1.

[0092] (3) If the SR resource triggered by the SL CSI report falls into the DRX off or inactive time, the SR is still sent or postponed to the SR resource closest to the DRX on / active time of the next DRX cycle.

[0093] Specifically, when the second condition is met, if the time domain of the SR resource triggered by the SL CSI report is during the DRX off or DRX inactive time, the SR is sent, or the SR is postponed to the SR resource closest to the DRX on or DRX active time of the next DRX cycle. It should be noted that this processing operation can be applied to mode 1.

[0094] (4) Limit the resource selection window for SL CSI reporting to the DRX on or DRX active time of the next DRX cycle.

[0095] Specifically, when the second condition is met, the resource selection window for the SL CSI report is required to fall within the DRX on or DRX active time period of the next DRX cycle. It should be noted that this processing operation can be applied to mode 2.

[0096] 3. Satisfy the third condition:

[0097] (1) If the configured SL CSI reporting behavior allows SL CSI reports to continue to be sent during DRX off or DRX inactive time, the processing operations are as follows:

[0098] When the third condition is met and the SL CSI reporting behavior is to allow continued transmission of the SL CSI report during DRX off or DRX inactive time, if the time domain of the transmission resource of the SL CSI report is within the DRX off or DRX inactive time, the SL CSI report is sent to the peer terminal;

[0099] When the third condition is met and the SL CSI reporting behavior is to allow continued transmission of SL CSI reports during DRX off or DRX inactive time, the SL CSI report latency requirement information or the current remaining latency requirement information is sent to the network side;

[0100] When the third condition is met and the SL CSI reporting behavior is to allow continued transmission of SL CSI reports during DRX off or DRX inactive time, if the time domain of the SR resource triggered by the SL CSI report is within the DRX off or DRX inactive time, send the SR, or postpone the sending of the SR to the SR resource closest to the DRX on or DRX active time of the next DRX cycle;

[0101] (2) If the configured SL CSI reporting behavior is to disallow the sending of SL CSI reports during DRX off or DRX inactive time, the processing operations are as follows:

[0102] When the third condition is met and the SL CSI reporting behavior is that the SL CSI report is not allowed to continue to be sent during the DRX off or DRX inactive time, the resource selection window for the SL CSI report is required to fall during the DRX on or DRX active time of the next DRX cycle;

[0103] When the third condition is met and the SL CSI reporting behavior is that the SL CSI report is not allowed to continue to be sent during the DRX off or DRX inactive time, if the time domain of the sending resource of the SL CSI report is during the DRX off or DRX inactive time, the triggered SL CSI report is canceled;

[0104] When the third condition is met and the SL CSI reporting behavior is not allowed to continue sending SL CSI reports during DRX off or DRX inactive time, if the time domain of the SR resource triggered by the SL CSI report is during DRX off or DRX inactive time, the triggered SR is canceled.

[0105] In some implementations, for a scenario where both the first DRX parameter configuration and the second DRX parameter configuration are common DRX parameter configurations, when a preset condition is met, performing a processing operation corresponding to the preset condition includes at least one of the following:

[0106] 1. Satisfy the first condition:

[0107] (1) If the sending resource of the SL CSI report falls into the DRX off or inactive time, the triggered SL CSI report is canceled.

[0108] Specifically, when the first condition is met, if the time domain of the sending resource of the SL CSI report is during DRX off or DRX inactive time, the triggered SL CSI report is canceled;

[0109] (2) If the SR resource triggered by the SL CSI report falls into the DRX off or inactive time, the triggered SR is canceled.

[0110] Specifically, when the first condition is met, if the time domain of the scheduling request SR resource triggered by the SL CSI report is during the DRX off or DRX inactive time, the triggered SR is canceled;

[0111] 2. Satisfy the second condition:

[0112] It should be noted that, in an embodiment of the present invention, compared with the scenario where the first DRX parameter configuration is different from the second DRX parameter configuration, in this scenario, if the second condition is met, the corresponding processing operation does not have the item "if the sending resource of the SL CSI report falls into DRX off or inactive time, still send the SL CSI report". The reason is that under the premise of shared DRX parameter configuration, even if the receiving end sends the SL CSI report, the transmitting end will definitely not receive the SLCSI report, so the corresponding processing operation in this scenario does not have this item.

[0113] (1) Report the delay requirement or current remaining delay requirement of the SL CSI report to the base station.

[0114] Specifically, when the second condition is met, the latency requirement information or the current remaining latency requirement information reported by the SL CSI is sent to the network side. Considering the need to send latency assistance information before the base station actually allocates resources, or when the allocated resources are found to be inappropriate, so that the base station can allocate appropriate resources. It should be noted that this processing operation can also be applied to mode 1.

[0115] (2) If the SR resource triggered by the SL CSI report falls into the DRX off or inactive time, the SR is still sent or postponed to the SR resource closest to the DRX on / active time of the next DRX cycle.

[0116] Specifically, when the second condition is met, if the time domain of the SR resource triggered by the SL CSI report is during the DRX off or DRX inactive time, the SR is sent, or the SR is postponed to the SR resource closest to the DRX on or DRX active time of the next DRX cycle. It should be noted that this processing operation can be applied to mode 1.

[0117] (3) Limit the resource selection window for SL CSI reporting to the DRX on or DRX active time of the next DRX cycle.

[0118] Specifically, when the second condition is met, the resource selection window for the SL CSI report is required to fall within the DRX on or DRX active time period of the next DRX cycle. It should be noted that this processing operation can be applied to mode 2.

[0119] 3. Satisfy the third condition:

[0120] (1) If the configured SL CSI reporting behavior allows SL CSI reports to continue to be sent during DRX off or DRX inactive time, the processing operations are as follows:

[0121] When the third condition is met and the SL CSI reporting behavior is to allow continued transmission of SL CSI reports during DRX off or DRX inactive time, the SL CSI report latency requirement information or the current remaining latency requirement information is sent to the network side;

[0122] When the third condition is met and the SL CSI reporting behavior is to allow continued transmission of SL CSI reports during DRX off or DRX inactive time, if the time domain of the SR resource triggered by the SL CSI report is within the DRX off or DRX inactive time, send the SR, or postpone the sending of the SR to the SR resource closest to the DRX on or DRX active time of the next DRX cycle;

[0123] (2) If the configured SL CSI reporting behavior is to disallow the sending of SL CSI reports during DRX off or DRX inactive time, the processing operations are as follows:

[0124] When the third condition is met and the SL CSI reporting behavior is that the SL CSI report is not allowed to continue to be sent during the DRX off or DRX inactive time, the resource selection window for the SL CSI report is required to fall during the DRX on or DRX active time of the next DRX cycle;

[0125] When the third condition is met and the SL CSI reporting behavior is that the SL CSI report is not allowed to continue to be sent during the DRX off or DRX inactive time, if the time domain of the sending resource of the SL CSI report is during the DRX off or DRX inactive time, the triggered SL CSI report is canceled;

[0126] When the third condition is met and the SL CSI reporting behavior is not allowed to continue sending SL CSI reports during DRX off or DRX inactive time, if the time domain of the SR resource triggered by the SL CSI report is during DRX off or DRX inactive time, the triggered SR is canceled.

[0127] It should be noted that, for situations where the first condition is not met, the existing mechanism can be directly followed for processing, which will not be elaborated here.

[0128] The method of the embodiment of the present application is described below in conjunction with specific implementation methods.

[0129] See also Figure 3a and Figure 3b , including a pair of UEs (UE1 and UE2) in SL unicast communication, in direction one UE1 is a TX UE and UE2 is a RX UE, in direction two UE1 is a RX UE and UE2 is a TX UE, and the DRX parameters of the two directions are configured independently. Figure 3aCorresponding to the situation where the first condition is met (the SL CSI report timer is short at this time), Figure 3b This corresponds to the case where the second condition is met (the SL CSI report timer is longer in this case).

[0130] Taking direction one as an example, the specific process is as follows:

[0131] Step 1: UE1 triggers UE2's SL CSI report through SL SCI, and UE2 starts the SL CSI report timer.

[0132] Specifically, before step 1, UE1 and UE2 have obtained their respective DRX parameter configurations, and the DRX parameter configurations in the two directions are independent.

[0133] Step 2: UE2 determines which of the following conditions the SL CSI reporting timer duration meets based on the DRX in its own direction (direction 1 in the figure):

[0134] Condition 1: The SL CSI reporting timer duration spans the DRX on / off boundary or the DRX activetime / inactive time boundary of the current DRX cycle

[0135] Condition 2: The SL CSI reporting timer duration includes the DRX on or DRX active time of the next DRX cycle

[0136] Condition 3: The network configures or the terminal pre-configures the SL CSI reporting behavior during DRX off or DRX inactive time, for example, 1 bit to indicate whether to continue reporting CSI reports during DRX off or DRX inactive time.

[0137] If condition 1 is not met, the existing mechanism is followed.

[0138] If condition 1 is met, but condition 2 is not met (such as Figure 3a ), do at least one of the following:

[0139] (1) If the sending resource of the SL CSI report falls into the DRX off or inactive time, the triggered SL CSI report is canceled;

[0140] (2) If the SR resource triggered by the SL CSI report falls into the DRX off or inactive time, the triggered SR is canceled.

[0141] If condition 2 is met (such as Figure 3b ), do at least one of the following:

[0142] (1) If the transmission resource of the SL CSI report falls into the DRX off or inactive time, the SL CSI report is still sent (for mode 1 and mode 2);

[0143] (2) Report the SL CSI report delay requirement or the current remaining delay requirement (for mode 1) to the base station;

[0144] (3) If the SR resource triggered by the SL CSI report falls into the DRX off or inactive time, the SR is still sent (for mode 1) or the SR is postponed to the SR resource closest to the DRX on / active time of the next DRX cycle (for mode 1).

[0145] (4) Limit the resource selection window for SL CSI reporting to the DRX on or DRX active time of the next DRX cycle (for mode 2).

[0146] If condition 3 is met (such as Figure 3b ), do at least one of the following:

[0147] (1) If 1 bit indicates that DRX is off or CSI reporting is allowed during the DRX inactive time, the relevant UE behavior includes at least one of the following:

[0148] a. If the sending resource of the SL CSI report falls into the DRX off or inactive time, the SLCSI report is still sent (for mode 1 and mode 2);

[0156] See also Figure 4a and Figure 4b , including a pair of UEs (UE1 and UE2) in SL unicast communication, in direction one UE1 is a TX UE and UE2 is a RX UE, in direction two UE1 is a RX UE and UE2 is a TX UE, and the DRX parameter configurations in both directions are shared.

[0159] Specifically, before step 1, UE1 and UE2 have obtained their respective DRX parameter configurations, and the DRX parameter configurations in the two directions are independent.

[0160] Step 2: UE2 determines which of the following conditions the SL CSI reporting timer duration meets based on the DRX in its own direction (direction 1 in the figure):

[0161] Condition 1: The SL CSI reporting timer duration spans the DRX on / off boundary or the DRX activetime / inactive time boundary of the current DRX cycle

[0162] Condition 2: The SL CSI reporting timer duration includes the DRX on or DRX active time of the next DRX cycle

[0169] (1) Report the SL CSI report delay requirement or the current remaining delay requirement (for mode 1) to the base station;

[0170] (2) If the SR resource triggered by the SL CSI report falls into the DRX off or inactive time, the SR is still sent (for mode 1) or the SR is postponed to the SR resource closest to the DRX on / active time of the next DRX cycle (for mode 1).

[0171] (3) Limit the resource selection window for SL CSI reporting to the DRX on or DRX active time of the next DRX cycle (for mode 2).

[0172] If condition 3 is met (such as Figure 3b ), do at least one of the following:

[0173] (1) If 1 bit indicates that DRX is off or CSI reporting is allowed during the DRX inactive time, the relevant UE behavior includes at least one of the following:

[0174] a. Report the delay requirement of the SL CSI report or the current remaining delay requirement (for mode 1) to the base station;

[0175] b. If the SR resource triggered by the SL CSI report falls into the DRX off or inactive time, the SR is still sent (for mode 1) or the SR is postponed to the SR resource closest to the DRX on / active time of the next DRX cycle (for mode 1).

[0176] (2) If 1 bit indicates that DRX is off or CSI report reporting is not allowed during DRX inactive time, the relevant UE behavior includes at least one of the following:

[0177] a. Limit the resource selection window for SL CSI reporting to the DRX on or DRX active time of the next DRX cycle (for mode 2).

[0178] b. If the sending resource of the SL CSI report falls into the DRX off or inactive time, the triggered SL CSI report is canceled;

[0179] c. If the SR resource triggered by the SL CSI report falls into the DRX off or inactive time, the triggered SR is canceled.

[0180] It is understandable that for the situation in direction 2, the specific process can refer to the process in direction 1 above, and will not be repeated here.
