Description

Technical Field

[0001] This application belongs to the field of wireless communication technology, specifically relating to a transmission control method, a terminal, and a network-side device. Background Technology

[0002] Sidelink (SL, also known as side link, secondary link, etc.) terminals within the base station's coverage area need to monitor downlink control information (DCI) sent by the base station, such as SL DCI for scheduling sidelink resources and / or UuDCI for Uu interface services. Continuous DCI monitoring consumes significant energy; therefore, a discontinuous reception (DRX) mechanism is needed to control the terminal's (User Equipment, UE) monitoring or transmission behavior to save power. The requirements of SL services typically differ from those of Uu services, and after the SL DCI schedules the terminal to perform SL transmission, the terminal may also need to receive SL feedback. Furthermore, the terminal may need to report the received SL feedback information to the base station. Therefore, compared to the Uu DCI scheduling and feedback reporting process, sidelink terminals also need to consider the SL feedback process. Thus, how sidelink terminals can implement a similar DRX mechanism and monitor DCI is a technical problem that needs to be solved. Summary of the Invention

The terms "system" and "network" in this application are often used interchangeably, and the described technologies can be used with the systems and radio technologies mentioned above, as well as with other systems and radio technologies. The following description describes New Radio (NR) systems for illustrative purposes, and NR terminology is used in most of the following description; however, these technologies can also be applied to applications beyond NR systems, such as 6th generation (6G) radio systems. th Generation 6G communication system.

[0027] Figure 1This diagram illustrates a wireless communication system applicable to embodiments of this application. The wireless communication system includes a relay UE 11, a network-side device 12, and a remote UE 13. In this embodiment, the remote UE 13 communicates with the relay UE 11 via a PC5 (secondary link) interface, the relay UE 11 communicates with the network-side device 12 via a Uu interface, and the remote UE 13 can also communicate with the network-side device 12 via a Uu interface.

[0028] In this embodiment, relay terminal 11 can also be referred to as relay terminal equipment or relay user equipment (UE), and remote terminal 13 can also be referred to as remote terminal equipment or remote UE. Relay terminal 11 and remote terminal 13 can be terminal-side devices such as mobile phones, tablet personal computers, laptop computers or notebook computers, personal digital assistants (PDAs), handheld computers, netbooks, ultra-mobile personal computers (UMPCs), mobile internet devices (MIDs), wearable devices or vehicle-mounted devices (VUEs), pedestrian terminals (PUEs), etc. Wearable devices include: wristbands, headphones, glasses, etc. It should be noted that the specific types of relay terminal 11 and remote terminal 13 are not limited in this application embodiment. Network-side device 12 can be a base station or a core network. The base station can be referred to as a node B, evolved node B, access point, base transceiver station (BTS), radio base station, radio transceiver, basic service set (BSS), extended service set (ESS), B node, evolved B node (eNB), home B node, home evolved B node, WLAN access point, WiFi node, transmitting and receiving point (TRP), or any other suitable term in the field, as long as the same technical effect is achieved. The base station is not limited to specific technical terms. It should be noted that in this application embodiment, only the base station in the NR system is used as an example, but the specific type of base station is not limited.

[0029] Starting with the 12th release, the Long Term Evolution (LTE) system supports sidelinks (SL, also known as side links, secondary links, etc.), allowing user equipment (UEs) to transmit data directly through secondary links without going through network equipment.

[0030] In New Radio (NR) sidelink systems, the UE sends sidelink control information (SCI) through the Physical Sidelink Feedback Channel (PSFCH), schedules the transmission of the Physical Sidelink Shared Channel (PSSCH) to send data, and can send back a sidelink hybrid automatic repeat request acknowledgement (HARQ-ACK) on the Physical Sidelink Feedback Channel (PSFCH).

[0031] NR sidelink supports two resource allocation modes: scheduled resource allocation (usually referred to as mode-1) and autonomous resource selection (usually referred to as mode-2). In the former, the network-side equipment controls and allocates resources to each UE, while in the latter, the UE autonomously selects resources.

[0032] In mode-1, the base station can schedule SL resources for the terminal by sending Downlink Control Information (DCI) or configuring SL resources for the terminal by configuring SL Configuration Grant (CG). Additionally, it can configure or indicate Physical Uplink Control Channel (PUCCH) resources for the terminal. The terminal reports the acquired sidelink HARQ-ACK information to the base station on the PUCCH to assist the base station in subsequent scheduling decisions. Taking SL resource scheduling via SL DCI as an example, the SL DCI schedules the SL resource located in slot n to the terminal. After the terminal uses this resource for SL transmission, it receives HARQ-ACK feedback on the corresponding PSFCH resource and reports the HARQ-ACK feedback to the base station on the subsequent PUCCH resource. The base station then determines whether retransmission is necessary based on the reported content.

[0033] To save power consumption in the SL UE, a DRX mechanism can be introduced in the SL. The existing DRX mechanism for the Uu PDCCH is called the Uu DRX mechanism. The DRX of the SL UE on the Uu interface is called bs-scheduled Uu DRX. The DRX used on the sidelink can be called SL DRX. The DCI for the base station to schedule sidelink resources can be called SL DCI. The SL DCI can use the DCI scheduled by the SL-related RNTI, or DCI format 3-0 or 3-1. The Uu DCI is the DCI for scheduling Uu transmissions or UuRS, or the DCI indicating the resource format, transmission power, or resource preemption status of Uu. For example, DCI format 0-x, DCI format 1-x, DCI format 2-x, where x is a natural number.

[0034] The DRX described in the embodiments of this application can be at least one of Uu DRX, bs-scheduled Uu DRX, and SL DRX.

[0035] The transmission control method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0036] Figure 2 This diagram illustrates a flow chart of a transmission control method according to an embodiment of this application. This method 200 can be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal. Figure 2 As shown, the method may include the following steps.

[0037] S210, the terminal performs a first operation based on the first situation, or the first situation and the second situation.

[0038] The first operation is an operation related to connectionless reception (DRX).

[0039] The first scenario includes: resource reporting. The second scenario includes at least one of the following: resource feedback from the side link, and feedback enabling.

[0040] In this embodiment of the application, the reported resources are resources such as the Physical Uplink Control Channel (PUCCH) and / or Physical Uplink Shared Channel (PUSCH) used to send SL-related HARQ-ACK and / or CSI to the control node.

[0041] In this embodiment of the application, the sidelink feedback resource is the feedback resource on SL, such as, but not limited to, PSFCH.

[0042] In the embodiments of this application, the first operation may include, but is not limited to, enabling or disabling the relevant timers for DRX, and / or monitoring target control information, and / or entering an inactive time, and / or entering an active time. For example, in one possible implementation, the first operation may include at least one of the following:

[0043] Start the first timer;

[0044] Entering inactive time;

[0045] It has been determined that the acquired DRX configuration does not include the first timer;

[0046] Do not enter inactive time;

[0047] Start the second timer;

[0048] Activation time begins;

[0049] Inactive time stops;

[0050] Do not start the first timer;

[0051] Deactivate the first timer;

[0052] Turn off the first timer;

[0053] Do not listen to target control information.

[0054] The first timer can be a timer that is inactive during its operation. The first timer may include a HARQ round-trip time (RTT) timer. That is, during the operation of the first timer, the terminal does not need to listen for control signaling and / or data, and / or the first timer is a HARQ RTT timer.

[0055] The second timer is a timer that is active during its running period; that is, during the running of the second timer, the terminal listens for control signaling and / or data. The second timer can be a retransmission timer. For example, the second timer may include at least one of the following: an inactivity timer (i.e., after the timer expires, the terminal enters an inactive period), a retransmission timer, or an on-duration timer.

[0056] In the embodiments of this application, the terminal can be a terminal that schedules SL resources for the controlled node, such as a mode-1 UE. Alternatively, the terminal can also be an SL terminal within the service coverage of the control node, such as at least one of the following: a mode-2 UE in idle state, a mode-2 UE in connected state, a mode-1 UE, etc.

[0057] The aforementioned control nodes can be network-side devices, such as eNBs, gNBs, roadside units, terminals with scheduling or control capabilities, or header terminals.

[0058] In the transmission control method provided in this application embodiment, the terminal performs a first operation based on a first situation or a first and a second situation. The first situation includes reporting resources; the second situation includes at least one of the following: sidelink resource feedback and feedback enabled. Therefore, based on the reported resource situation, the sidelink resource feedback situation, and / or the feedback enabled situation, operations related to the DRX mechanism can be determined, and the DRX mechanism can be implemented in the sidelink.

[0059] In one possible implementation, the first case includes at least one of the following (a) to (b):

[0060] (i) No reporting resources were obtained. For example, the base station did not provide PUCCH configuration (PUCCHConfig) for the terminal, or the SL CG configuration did not contain PUCCH configuration information.

[0061] (ii) The reported resource meets the first condition. For example, the reported resource obtained by the terminal meets the first condition. When the first condition is met, it can be determined that the reported resource is unusable.

[0062] Optionally, the reported resources meet at least one of the following conditions (1) to (20):

[0063] (1) No scheduled resource reporting. For example, no scheduled PUCCH is in SL DCI.

[0064] (2) SL DCI indicates that no resources are reported. For example, SL DCI indicates that there is no PUCCH.

[0065] (3) The SL DCI does not indicate the reporting of resources. For example, the SL DCI does not indicate PUCCH.

[0066] (4) The SL CG configuration does not include reporting resources. For example, the SL CG configuration does not include PUCCH configuration information.

[0067] (5) The SL CG configuration indicates that no resources have been reported. For example, the SL CG configuration indicates that there is no configuration information for PUCCH.

[0068] (6) At least some of the resources indicated by SL CG or SL DCI are not in use. If at least some of the resources indicated by SL CG or SL DCI are in use, it can be determined that the corresponding reported resources are also unusable. For example, all the resources indicated by SL CG or SL DCI are unusable.

[0069] (7) Transmission of at least some of the resources indicated by SL CG or SL DCI is dropped. For example, transmission of at least some of the resources indicated by SL CG or SL DCI is dropped due to a conflict with other transmissions.

[0070] (8) The transmission of at least some of the resources indicated by SL CG or SL DCI is cancelled. For example, the transmission of at least some of the resources indicated by SL CG or SL DCI is cancelled due to a conflict with other transmissions.

[0071] (9) At least a portion of the resources indicated by SL CG or SL DCI have a first priority, wherein the first priority is a specified or particular priority;

[0072] (10) At least some of the resources indicated by SL CG or SL DCI have their priority reduced. For example, when a higher priority value corresponds to a lower priority, one way to reduce the priority is to increase its priority value.

[0073] (11) At least some of the resources indicated by SL CG or SL DCI have a priority of the second value. For example, because at least some of the resources indicated by SL CG or SL DCI have a priority lower than the second value, they do not meet the priority transmission conditions, resulting in at least some of the resources indicated by SL CG or SL DCI being unusable.

[0074] (12) At least some of the resources indicated by SL CG or SL DCI do not have a corresponding priority. For example, at least some of the resources indicated by SLCG or SL DCI do not have a corresponding Uu priority, or at least some of the resources indicated by SL CG or SL DCI do not have a corresponding sidelink priority, making it impossible to report using the corresponding reporting resources.

[0075] (13) Invalidity of at least some of the resources indicated by SL CG or SL DCI.

[0076] In the cases described in (6) to (13) above, the reported resources may become unusable indirectly.

[0077] (14) The transmission of resource reporting was cancelled. For example, the transmission of resource reporting was cancelled due to a conflict with other transmissions.

[0078] (15) The transmission of the reported resource was dropped. For example, the transmission of the reported resource conflicted with other resources, and the reported resource was dropped.

[0079] (16) The priority of the reported resources is the second priority, where the second priority is a specified or particular priority.

[0080] (17) The priority of the reported resource is deprioritized. For example, if the reported resource conflicts with other resources, the priority of the reported resource is reduced, resulting in the reported resource being unusable for a certain period of time. For example, when a higher priority value corresponds to a lower priority, one way to reduce the priority is to increase its priority value.

[0081] (18) The priority of the reported resource is lower than the first value. For example, because the priority of the reported resource is lower than the first value, it does not meet the priority transmission condition, which results in the reported resource being unusable.

[0082] (19) The reported resource does not have a corresponding priority. For example, the reported resource does not have a corresponding Uu priority, or the reported resource does not have a corresponding sidelink priority, which makes it impossible to use the reported resource for SL HARQ ACK reporting.

[0083] (20) The reported resource is invalid. For example, PUCCH is invalid and therefore cannot be used for transmission.

[0084] (iii) Reporting resources are configured. For example, the base station provides a PUCCH Config, or the SL CG configuration includes PUCCH information, and indicates, schedules, or expects the normal transmission of the PUCCH. In this possible implementation, it can be assumed that sidelink feedback resources or configurations for obtaining sidelink feedback resources are obtained in this situation.

[0085] (iv) Reporting resources are scheduled. For example, SL DCI schedules PUCCH. In this possible implementation, it can be assumed that sidelink feedback resources or the configuration for obtaining sidelink feedback resources are obtained in this situation.

[0086] In one possible implementation, configuring or scheduling reporting resources may include at least one of the following (1) to (7):

[0087] (1) Obtain the reported resource. For example, the terminal obtains the PUCCH resource.

[0088] (2) Obtain the configuration of the reported resource. For example, the terminal obtains the configuration of the PUCCH resource, such as the PUCCH configuration or the SL CG configuration including PUCCH information.

[0089] (3) Report that a resource has been scheduled. For example, SL DCI scheduled PUCCH.

[0090] (4) SL DCI indicates the reporting resource. For example, SL DCI indicates PUCCH.

[0091] (5) SL DCI indicates that there are reporting resources. For example, SL DCI indicates that there is PUCCH.

[0092] (6) The SL CG configuration includes reporting resources. For example, the SL CG configuration includes PUCCH.

[0093] (7) The SL CG configuration indicates that there are reporting resources. For example, the SL CG configuration indicates that there is a PUCCH.

[0094] In one possible implementation, the sidelink feedback resource includes at least one of the following (a) to (v):

[0095] (i) Obtain the sidelink feedback resource. For example, obtain the PSFCH.

[0096] (ii) Obtain the configuration of the sidelink feedback resources. For example, obtain the configuration of PSFCH.

[0097] (iii) No sidelink feedback resources were obtained. For example, PSFCH was not obtained.

[0098] (iv) The configuration of the sidelink feedback resource was not obtained. For example, the configuration of PSFCH was not obtained;

[0099] (v) The sidelink feedback resource meets the second condition. For example, the sidelink feedback resource obtained by the terminal meets the second condition. Wherein, the sidelink feedback resource meeting the second condition indicates that the sidelink feedback resource is unusable. Optionally, the sidelink feedback resource meeting the second condition includes at least one of the following (1) to (7):

[0100] (1) The transmission of sidelink feedback resources is discarded.

[0101] (2) The transmission of sidelink feedback resources is cancelled.

[0102] (3) The priority of the side link feedback resource is the third priority, where the third priority is a specified or particular priority.

[0103] (4) The priority of the side link feedback resources is reduced.

[0104] (5) The priority of the side link feedback resource is the third value.

[0105] (6) There is no corresponding priority for the side link feedback resources.

[0106] (7) Side link feedback resources are invalid.

[0107] In one possible implementation, the feedback enable condition includes at least one of the following:

[0108] (i) Feedback Enable. For example, SL HARQ-ACK is enabled, or no logical channel (or logical channel group) is configured to enable feedback, or all configured logical channels (or logical channel groups) have feedback enabled, or at least one logical channel (or logical channel group) has feedback enabled.

[0109] (ii) Feedback de-enabled. For example, SL HARQ-ACK is de-enabled, or no logical channel (or logical channel group) is configured to enable feedback, or all configured logical channels (or logical channel groups) are configured to enable feedback.

[0110] In one possible implementation, the terminal performs a first operation based on a first case and a second case, which may include:

[0111] When the first case is the first sub-case and the second case is the second sub-case, the terminal performs the first operation.

[0112] The first sub-case includes one of the following:

[0113] No reported resources were obtained;

[0114] The reported resources are unavailable.

[0115] The second sub-case includes at least one of the following:

[0116] Obtain the sidelink feedback resource or obtain the configuration of the sidelink feedback resource;

[0117] Feedback enables or feedback de-enables.

[0118] The first operation includes one of the following (1) to (6):

[0119] (1) Start the first timer and / or enter the inactive time;

[0120] In this embodiment, the first timer can be a timer that is inactive during its operation, and the first timer may include a HARQ round-trip time (RTT) timer. That is, during the operation of the first timer, the terminal does not need to listen to control signaling and / or data, and / or the first timer is a HARQ RTT timer.

[0121] In this possible implementation, since the side link feedback resource is obtained or the configuration of the side link feedback resource is obtained, and / or the feedback is enabled or the feedback is disabled, but the reporting resource is not obtained or the reporting resource is unusable, retransmission scheduling is required by default (e.g., it can be agreed upon by the protocol or pre-configured). Therefore, in order to reduce power consumption, the terminal starts the first timer and / or enters the inactive time.

[0122] (2) Do not start the first timer, and / or do not enter the inactive time, and / or start the second timer, and / or enter the active time.

[0123] The second timer is a timer that is active during its running period. That is, during the operation of the second timer, the terminal listens for control signaling and / or data. The second timer can be a retransmission timer. For example, the second timer may include at least one of the following: an inactivity timer (i.e., after the timer expires, the terminal enters an inactive period), a retransmission timer, or an on-duration timer.

[0124] In this possible implementation, if a sidelink feedback resource or its configuration is obtained, and / or feedback is enabled or disabled, but no reporting resource is obtained or the reporting resource is unavailable, then retransmission scheduling based on HARQ-ACK feedback cannot be performed. Therefore, it is unnecessary to use or enable the RTT timer, and thus the first timer can be left unenabled. Furthermore, the terminal can also enable a second timer and / or not enter inactive time and / or stop during active time and / or inactive time to monitor control signaling and / or data.

[0125] (3) Determine that the acquired discontinuous reception DRX configuration does not include the first timer, and / or does not enter the inactive time, and / or starts the second timer, and / or enters the active time, and / or stops the inactive time.

[0126] In this possible implementation, if a sidelink feedback resource or its configuration is obtained, and / or feedback is enabled or disabled, but no reporting resource is obtained or the reporting resource is unavailable, it indicates that retransmission scheduling based on HARQ-ACK feedback cannot be performed. Therefore, it is unnecessary to use or enable the RTT timer. Thus, it can be determined that the obtained discontinuous reception DRX configuration does not include the first timer. Furthermore, the terminal can also enable a second timer and / or not enter inactive time and / or stop entering active time and / or inactive time to monitor control signaling and / or data.

[0127] (4) The first timer is de-enabled, and / or does not enter the inactive time, and / or the second timer is enabled, and / or enters the active time, and / or the inactive time is stopped.

[0128] In this possible implementation, if a sidelink feedback resource or its configuration is obtained, and / or feedback is enabled or disabled, but no reporting resource is obtained or the reporting resource is unavailable, it indicates that retransmission scheduling based on HARQ-ACK feedback cannot be performed. Therefore, it is unnecessary to use or enable the RTT timer, and the first timer can be disabled. Furthermore, the terminal can also enable a second timer and / or not enter inactive time and / or stop during active time and / or inactive time to monitor control signaling and / or data.

[0129] (5) Turn off the first timer, and / or do not enter the inactive time, and / or turn on the second timer, and / or enter the active time, and / or stop the inactive time;

[0130] In this possible implementation, if a sidelink feedback resource or its configuration is obtained, and / or feedback is enabled or disabled, but no reporting resource is obtained or the reporting resource is unavailable, it indicates that retransmission scheduling based on HARQ-ACK feedback cannot be performed. Therefore, it is unnecessary to use or enable the RTT timer, and the first timer can be disabled. Furthermore, the terminal can also enable a second timer and / or not enter inactive time and / or stop during active time and / or inactive time to monitor control signaling and / or data.

[0131] (6) Do not listen to target control information.

[0132] For example, if PUCCH is not configured or is configured but cannot be used, and if PSFCH is configured, then enable the RTT timer or disable the RTT timer or do not monitor SL DCI or Uu DCI.

[0133] Optionally, the terminal may not monitor the target control information for a period of time after a certain moment has begun.

[0134] In one possible implementation, the target control information includes, but is not limited to, target DCI and / or target SCI. Optionally, the target DCI includes at least one of the following: SL DCI, Uu DCI.

[0135] In this possible implementation, since the side link feedback resource is obtained or the configuration of the side link feedback resource is obtained, and / or the feedback is enabled or the feedback is disabled, but the reporting resource is not obtained or the reporting resource is unavailable, the network-side device can default (e.g., it can be agreed upon by the protocol or pre-configured) not to retransmit the schedule for a period of time. Therefore, in order to save the power consumption of the terminal, the terminal may not monitor the target control information.

[0136] Optionally, at least one of the first timer and the second timer described above may be a timer configured for Uu DRX or a timer configured for SL DRX.

[0137] In the above possible implementations, the terminal can perform the first operation at the first moment, that is, when the terminal arrives at the first moment, it performs the first operation.

[0138] Optionally, the corresponding time can be configured for either the Uu DRX or the SL DRX at the first moment.

[0139] In one possible implementation, the first time may include one of the following:

[0140] (1) First target time.

[0141] (2) The sum of the first target time and the first offset time.

[0142] (3) The difference between the first target time and the second offset time.

[0143] In the above possible implementations, the first offset time and the second offset time can be a symbol or a slot. For example, the first time is the next symbol or the next slot after the first target time. For example, if the first target time is the time when a NACK is received or the time of side link feedback resources, one implementation is that the first time is the next symbol or the next slot after the time when a NACK is received or the time of side link feedback resources.

[0144] In one possible implementation, the first target time may include at least one of the following:

[0145] (1) Preset the timing of the downlink control information (DCI) for the side link (SL). For example, the timing of the SL DCI obtained by the terminal.

[0146] (2) Preset transmission time.

[0147] For example, the time of the Nth transmission (N is a natural number, e.g., the first or last transmission) in the sidelink grant obtained by the terminal (where the sidelink grant may include at least one of the configured sidelink grant, the grant provided by the SL DCI, and the grant selected by the terminal). Optionally, this transmission may be a PSCCH or a first-stage SCI, such as SCI format 1-A. Alternatively, the transmission may be a second-stage SCI, such as SCI format 2-A or SCI format 2-B. Or, the transmission may also be a PSSCH.

[0148] (3) Preset the time of the side link feedback resource.

[0149] For example, the time of the sidelink feedback resource corresponding to the Mth transmission (M is a natural number, such as the first or last transmission) in the acquired sidelink license, such as the time of the PSFCH corresponding to a certain transmission.

[0150] (4) Preset the start or end time of the side link authorization cycle.

[0151] For example, the start or end time of the period of the sidelink grant obtained by the terminal (wherein, the sidelink grant may include at least one of the configured sidelink grant, the grant provided by SL DCI, and the grant selected by the terminal).

[0152] (5) The time when a non-acknowledgment message is sent or received. That is, the moment when the terminal sends a NACK or receives a NACK.

[0153] (6) Determine the time of transmission failure. For example, the terminal determines the moment of transmission failure.

[0154] (7) Preset the time corresponding to the reported resource. For example, the time corresponding to the reported resource obtained by the terminal. This item applies to the first case, including situations where the reported resource is unavailable.

[0155] For example, the reporting resource indicated in SL DCI, or the time corresponding to the reporting resource included in SL CG configuration.

[0156] It should be noted that if the first target time includes multiple of the above-mentioned factors, it indicates that the terminal will perform the first operation at each of the corresponding first times.

[0157] For example, the RTT timer is started at time A (i.e., the first time), where time A can be the time when at least one of SL DCI, PSCCH, PSSCH and PSFCH is located, or the time when at least one of SL DCI, PSCCH, PSSCH and PSFCH is located forward or backward by the corresponding offset.

[0158] In another possible implementation, the terminal performs a first operation based on a first situation and a second situation, including: when the first situation is a first sub-situation and the second situation is a third sub-situation, the terminal performs the first operation.

[0159] Among them, the first sub-case is the same as the first sub-case in the above possible implementation, and the first sub-case in this possible implementation includes one of the following: no reported resource was obtained; the reported resource meets the first condition;

[0160] The third sub-case may include at least one of the following:

[0161] No sidelink feedback resource was obtained, or the configuration of the sidelink feedback resource was not obtained, or the sidelink feedback resource meets the second condition.

[0162] Feedback enables or feedback de-enables.

[0163] In the above possible implementations, the first operation includes at least one of the following (1) to (5):

[0164] (1) Do not start the first timer, and / or do not enter the inactive time, and / or start the second timer, and / or enter the active time, and / or stop the inactive time.

[0165] The first and second timers in this possible implementation are the same as those in the possible implementations described above, and will not be repeated here.

[0166] In this possible implementation, if no reporting resources and side link feedback resources are obtained, or if the obtained reporting resources are unusable and the configuration of side link feedback resources is not obtained, it means that retransmission and retransmission scheduling based on HARQ-ACK feedback cannot be performed. Therefore, it is unnecessary to use or enable the RTT timer. Thus, the first timer is not enabled.

[0167] On the other hand, since no sidelink feedback resources and reporting resources are obtained, it is impossible to determine when there will be retransmissions and scheduled retransmissions. Therefore, a second timer can be directly started for monitoring, and / or the timer can be stopped during the inactive time and / or during the active time and / or during the inactive time.

[0168] Furthermore, if the second timer expires and the terminal still has not received control signaling and / or data from the network-side device, it indicates that the network-side device may not have the intention to continue scheduling. Therefore, the terminal may stop monitoring the control channel and / or data, and / or enter sleep mode to save power consumption.

[0169] (2) Determine that the acquired discontinuous reception DRX configuration does not include the first timer, and / or does not enter the inactive time, and / or enables the second timer, and / or enters the active time, and / or stops the inactive time.

[0170] In this possible implementation, determining that the DRX configuration does not include an RTT timer could mean that an RTT timer is not needed.

[0171] In this possible implementation, if no reporting resources and side link feedback resources are obtained, or if the obtained reporting resources are unusable and no side link feedback resources are obtained, it means that retransmission and retransmission scheduling based on HARQ-ACK feedback cannot be performed. Therefore, it is not necessary to use or enable the RTT timer. Thus, if the DRX configuration does not include the RTT timer, it can be determined that the RTT timer is not needed.

[0172] On the other hand, since no sidelink feedback resources and reporting resources are obtained, it is impossible to determine when there will be retransmissions and scheduled retransmissions. Therefore, a second timer can be directly started for monitoring, and / or the timer can be stopped during the inactive time and / or during the active time and / or during the inactive time.

[0173] Furthermore, if the second timer expires and the terminal still has not received control signaling and / or data from the network-side device, it indicates that the network-side device may not have the intention to continue scheduling. Therefore, the terminal may stop monitoring the control channel and / or data, and / or enter sleep mode to save power consumption.

[0174] (3) The first timer is de-enabled, and / or does not enter the inactive time, and / or the second timer is enabled, and / or enters the active time, and / or the inactive time is stopped.

[0175] In this possible implementation, if no reporting resources and side link feedback resources are obtained, or if the obtained reporting resources are unusable and no side link feedback resources are obtained, it means that retransmission and retransmission scheduling based on HARQ-ACK feedback cannot be performed. Therefore, it is not necessary to use or enable the RTT timer. Thus, the first timer is deenabled.

[0176] On the other hand, since no sidelink feedback resources and reporting resources are obtained, it is impossible to determine when there will be retransmissions and scheduled retransmissions. Therefore, a second timer can be directly started for monitoring, and / or the timer can be stopped during the inactive time and / or during the active time and / or during the inactive time.

[0177] Furthermore, if the second timer expires and the terminal still has not received control signaling and / or data from the network-side device, it indicates that the network-side device may not have the intention to continue scheduling. Therefore, the terminal may stop monitoring the control channel and / or data, and / or enter sleep mode to save power consumption.

[0178] (4) The first timer is turned off, and / or does not enter the inactive time, and / or the second timer is turned on, and / or enters the active time, and / or the inactive time is stopped.

[0179] In this possible implementation, if no reporting resources and side link feedback resources are obtained, or if the obtained reporting resources are unusable and no side link feedback resources are obtained, it means that retransmission and retransmission scheduling based on HARQ-ACK feedback cannot be performed. Therefore, it is not necessary to use or enable the RTT timer, and thus the first timer is turned off.

[0180] On the other hand, since no sidelink feedback resources and reporting resources are obtained, it is impossible to determine when there will be retransmissions and scheduled retransmissions. Therefore, a second timer can be directly started for monitoring, and / or the timer can be stopped during the inactive time and / or during the active time and / or during the inactive time.

[0181] Furthermore, if the second timer expires and the terminal still has not received control signaling and / or data from the network-side device, it indicates that the network-side device may not have the intention to continue scheduling. Therefore, the terminal may stop monitoring the control channel and / or data, and / or enter sleep mode to save power consumption.

[0182] (5) Start the first timer and / or enter the inactive time.

[0183] In this possible implementation, since no reported resources are obtained or the reported resources are unavailable, retransmission scheduling is required by default (e.g., by agreement or pre-configuration). Therefore, in order to reduce power consumption, the terminal starts a first timer and / or enters an inactive time, waits for the first timer to expire, and then listens for retransmission scheduling information.

[0184] For example, the UE starts the RTT timer at time A, where time A can be the time when SL DCI, PSCCH, and PSSCH are located, or it can be the time when SL DCI, PSCCH, and PSSCH are located forward or backward by the corresponding offset.

[0185] For example, if PUCCH is not configured or is configured but cannot be used, and if PSFCH is not configured, the terminal will not enable the RTT timer.

[0186] In the above possible implementations, the terminal performing the first operation may include: performing the first operation at a second time; wherein the second time includes one of the following: a first target time, the sum of the first target time and a third offset time, and the difference between the first target time and a fourth offset time.

[0187] In other words, the terminal can execute the first operation when the second time arrives. That is, the terminal executes the first operation at the moment corresponding to the second time.

[0188] Optionally, the second time mentioned above can be configured for Uu DRX or for SL DRX.

[0189] The first target time mentioned above is the same as the first target time in the above possible implementation methods. For details, please refer to the description in the above possible implementation methods, which will not be repeated here.

[0190] Optionally, the third and fourth offset times are one symbol or one slot. For example, the second time is the next symbol or the next slot after the first target time. If the first target time is the time when a NACK is received or the time of sidelink feedback resources, one implementation is that the second time is the next symbol or the next slot after the time when a NACK is received or the time of sidelink feedback resources.

[0191] In yet another possible implementation, the terminal performs a first operation based on a first case and a second case, including: when the first case is a fourth sub-case, the terminal performs the first operation.

[0192] The fourth sub-case includes: having configured reporting resources or having scheduled reporting resources. For details regarding the possible scenarios of having configured or scheduled reporting resources, please refer to the descriptions in the above-mentioned possible implementation methods.

[0193] The first operation includes at least one of the following:

[0194] (1) Start the first timer and / or enter the inactive time.

[0195] For example, the UE starts the RTT timer at time A, where time A can be the time when SL DCI, PSCCH, PSSCH, PSFCH, PUCCH, or PUSCH are located, or it can be the time when SL DCI, PSCCH, PSSCH, PSFCH, PUCCH, or PUSCH are located forward or backward by the corresponding offset time.

[0196] (2) Do not listen to target control information.

[0197] The target control information is the same as the target control information in the above possible implementations. For details, please refer to the above description of the target control information, which will not be repeated here.

[0198] Optionally, the terminal may not listen to the target control information for a period of time after a certain moment begins. For example, for a period of time starting from moment B, the UE may not monitor Uu DCI and / or SL DCI, and / or enter sleep mode to save power consumption.

[0199] In the above possible implementations, in the fourth sub-case, the second case can be assumed to be either obtaining a sidelink feedback resource or obtaining a configuration for obtaining a sidelink feedback resource. For example, obtaining a PSFCH or obtaining a configuration for obtaining a PSFCH.

[0200] Alternatively, the first operation described above can be performed when the first case is the fourth sub-case, and the second case is when the side link feedback resource is obtained or the configuration of the side link feedback resource is obtained.

[0201] For example, if PUCCH is configured or scheduled (optionally, in this case, PSFCH can be assumed to be configured), the terminal will enable the RTT timer.

[0202] In the above possible implementations, the terminal can perform the first operation when the third time arrives. The third time may include one of the following: the second target time, the sum of the second target time and the fifth offset time, or the difference between the second target time and the sixth offset time.

[0203] Optionally, the fifth and sixth offset times can be a symbol or a slot. For example, the third time is the next symbol or the next slot after the second target time. If the second target time is the time when a NACK is received or the time of sidelink feedback resources, one implementation is that the third time is the next symbol or the next slot after the time when a NACK is received or the time of sidelink feedback resources.

[0204] In the above possible implementations, the second target time may optionally include at least one of the following:

[0205] (1) Preset the start or end time of the side link authorization period; for example, the start or end time of the side link authorization period obtained by the terminal.

[0206] (2) The time when the non-acknowledgment feedback information is received; for example, the time when the terminal receives the NACK.

[0207] (3) Preset the time corresponding to the reported resources.

[0208] It should be noted that although the above embodiments only provide some behaviors or combinations of behaviors included in the first operation when the first situation is a certain specific situation, or when the first situation is a certain specific situation and the second situation is a certain specific situation, it is not limited to this. In specific applications, the first operation may also include combinations of other behaviors, which are not limited in the specific embodiments of this application.

[0209] It should be noted that although the above provides some specific situations in which the terminal performs the first operation when reporting resources, providing feedback resources from the side link, and enabling feedback, it is not limited to these. In other situations not given, the terminal may also determine the first operation to perform based on the first situation, or the first situation and the second situation.

[0210] Table 1 shows the first operation that the terminal may perform under various circumstances in one optional implementation of the embodiments of this application.

[0211] Table 1.

[0212]

[0213]

[0214] In the table, NA means that such a situation (or combination) may not occur, or that such a situation is an error case, or that the terminal does not expect such a situation to occur.

[0215] Figure 3 This diagram illustrates a flowchart of another transmission control method provided in an embodiment of this application, which can be executed by a network-side device. In other words, the method can be executed by software or hardware installed on the network-side device. Figure 3 As shown, the method may include the following steps.

[0216] S310, the network-side device performs the second operation based on the third situation, or the third situation and the fourth situation;

[0217] The second operation is an operation related to DRX.

[0218] The third situation includes: the situation of reporting resources;

[0219] The fourth case includes at least one of the following: the case of sidelink feedback resources, the case of feedback enabled.

[0220] The transmission control method 300 provided in this application embodiment is a method step of a network-side device corresponding to method 200, and has the same or corresponding possible implementations as method 200. The following mainly describes the parts of method 300 that are different from method 200. For other parts that are the same or corresponding, please refer to the relevant descriptions in method 200.

[0221] In one possible implementation, similar to the first case in method 200, the third case may include at least one of the following (a) to (b):

[0222] (i) No reporting resources have been configured;

[0223] For example, the network-side device does not provide PUCCH configuration for the terminal, or the SL CG configuration provided by the network-side device to the terminal does not include PUCCH information.

[0224] (ii) The reported resource meets the first condition, for example, the reported resource configured by the network-side device for the terminal meets the first condition. In the case that the reported resource meets the first condition, the reported resource cannot be used. Optionally, the reported resource meeting the first condition may include at least one of the following (1) to (20):

[0225] (1) No scheduled reporting resources. For example, the SL DCI sent by the network-side device to the terminal does not include a scheduled PUCCH.

[0226] (2) The side link DCI indicates that no resources are reported. For example, the SL DCI sent by the network-side device to the terminal indicates that there is no PUCCH.

[0227] (3) The side link DCI does not indicate the reported resources. For example, the SL DCI sent by the network-side device to the terminal does not indicate PUCCH.

[0228] (4) The SL CG configuration does not include reporting resources. For example, the SL CG configuration provided by the network-side device to the terminal does not include PUCCH.

[0229] (5) The SL CG configuration indicates that no resources have been reported. For example, the SL CG configuration provided by the network-side device to the terminal indicates that PUCCH is not included.

[0230] (6) At least some of the resources indicated by SL CG or SL DCI are not in use. For example, all resources indicated by SL CG or SLDCI are invalid.

[0231] (7) The transmission of at least a portion of the resources indicated by SL CG or SL DCI is dropped.

[0232] (8) The transmission of at least a portion of the resources indicated by SL CG or SL DCI is cancelled.

[0233] (9) At least some of the resources indicated by SL CG or SL DCI have the first priority.

[0234] (10) At least some of the resources indicated by SL CG or SL DCI have their priority reduced.

[0235] (11) At least some of the resources indicated by SL CG or SL DCI have a priority of the second value.

[0236] (12) At least some of the resources indicated by SL CG or SL DCI do not have a corresponding priority.

[0237] (13) Invalidity of at least some of the resources indicated by SL CG or SL DCI.

[0238] (14) The transmission of the reported resource is cancelled. For example, the PUCCH transmission conflicts with other transmissions, thus causing the PUCCH transmission to be cancelled.

[0239] (15) The transmission of the reported resource is dropped. For example, if the PUCCH resource overlaps with the resources of other transmissions, the PUCCH resource is dropped.

[0240] (16) The priority of reporting resources is the second priority.

[0241] (17) The priority of the reported resource is reduced. For example, if the PUCCH resource overlaps with other transmission resources, the priority of the PUCCH resource is reduced, thus making transmission impossible.

[0242] (18) The priority of the reported resource is lower than the first value. For example, if the priority of PUCCH is lower than the first value, it does not meet the priority transmission condition, thus making it impossible for PUCCH to be transmitted.

[0243] (19) The reported resource does not have a corresponding priority; for example, the reported resource does not have a corresponding Uu priority, or the reported resource does not have a corresponding sidelink priority, thus making it impossible to use the reported resource for SL HARQ ACK reporting.

[0244] (20) The reported resource is invalid. For example, PUCCH is invalid and therefore cannot be used for transmission.

[0245] (iii) Reporting resources are configured. For example, the network-side device provides the terminal with PUCCH configuration, or the SL CG configuration provided by the network-side device to the terminal includes PUCCH information and indicates, schedules, or expects the normal transmission of the PUCCH. In this possible implementation, it can be assumed that sidelink feedback resources or configurations for obtaining sidelink feedback resources are obtained in this situation by default.

[0246] (iv) Reporting resources are scheduled. For example, SL DCI schedules PUCCH. In this possible implementation, it can be assumed that sidelink feedback resources or the configuration for obtaining sidelink feedback resources are obtained in this situation.

[0247] In one possible implementation, configuring or scheduling reporting resources may include at least one of the following (1) to (6):

[0248] (1) Reporting resources are configured. For example, the network-side device provides the terminal with PUCCH configuration, or the network-side device provides the terminal with SL CG configuration containing PUCCH information.

[0249] (2) Reporting that resources have been scheduled. For example, the SL DCI sent by the network-side device schedules the PUCCH.

[0250] (3) SL DCI indicates the reporting resource. For example, SL DCI indicates PUCCH.

[0251] (4) SL DCI indicates that there are reporting resources. For example, SL DCI indicates that there is PUCCH.

[0252] (5) The SL CG configuration includes reporting resources. For example, the SL CG configuration includes PUCCH.

[0253] (6) The SL CG configuration indicates that there are reporting resources. For example, the SL CG configuration indicates that there is a PUCCH.

[0254] In one possible implementation, the sidelink feedback resource includes at least one of the following (a) to (iii):

[0255] (i) Sidelink feedback resources are configured. For example, the network-side device has configured PSFCH in SL DCI.

[0256] (ii) No configuration of sidelink feedback resources; for example, the network-side device does not configure PSFCH in SL DCI.

[0257] (iii) The sidelink feedback resource meets the second condition. For example, the sidelink feedback resource configured by the network-side device for the terminal meets the second condition. The sidelink feedback resource meeting the second condition can indicate that the sidelink feedback resource is unusable. Optionally, the sidelink feedback resource meeting the second condition may include at least one of the following:

[0258] (1) The transmission of sidelink feedback resources is discarded;

[0259] (2) The transmission of sidelink feedback resources is cancelled;

[0260] (3) The priority of the side link feedback resource is the third priority;

[0261] (4) The priority of side-link feedback resources is reduced;

[0262] (5) The priority of the side link feedback resource is the third value;

[0263] (6) There is no corresponding priority for the side link feedback resources;

[0264] (7) Side link feedback resources are invalid.

[0265] In one possible implementation, the feedback enable condition includes at least one of the following:

[0266] (i) Feedback Enable. For example, SL HARQ-ACK is enabled, or no logical channel (or logical channel group) is configured to enable feedback, or all configured logical channels (or logical channel groups) have feedback enabled, or at least one logical channel (or logical channel group) has feedback enabled.

[0267] (ii) Feedback de-enabled. For example, SL HARQ-ACK is de-enabled, or no logical channel (or logical channel group) is configured to enable feedback, or all configured logical channels (or logical channel groups) are configured to enable feedback.

[0268] In one possible implementation of S310, when the third case is the fifth sub-case and the fourth case is the sixth sub-case, the network-side device performs a second operation, wherein the second operation includes one of the following:

[0269] (1) Determine if the first timer is enabled and / or determine if the inactive period has started. Specifically, determining if the first timer is enabled by the network-side device can mean that the network-side device determines if the terminal's first timer is enabled, or the network-side device can set a first timer for the terminal, and determining if the first timer is enabled by the network-side device means that the network-side device enables the first timer. Determining if the terminal enters the inactive period means that the network-side device determines that the terminal enters the inactive period, during which the network-side device does not send loss control signaling and / or data to the terminal.

[0270] Optionally, during the operation of the first timer, the network-side device does not need to transmit control signaling and / or data; and / or, the first timer is a HARQ RTT timer.

[0271] (2) Determine that the first timer is not turned on, and / or determine that the inactive time is not entered, and / or determine that the second timer is turned on, and / or determine that the active time is entered, and / or the inactive time is stopped.

[0272] Specifically, the network-side device determining that the first timer is not enabled can mean that the network-side device determines that the terminal's first timer is not enabled, or that the network-side device can set a first timer for the terminal, and the network-side device determining that the first timer is not enabled means that the network-side device does not enable its own first timer. The network-side device determining not to enter the inactive time means that the network-side device determines that the terminal will not enter the inactive time, and the network-side device can send loss-of-control signaling and / or data to the terminal.

[0273] Similarly, the network-side device determining that the second timer is enabled can be either the network-side device determining that the terminal's second timer is enabled, or the network-side device setting a second timer for the terminal, and the network-side device determining that the second timer is enabled means that the network-side device enables its second timer.

[0274] Optionally, during the operation of the second timer, the network-side device transmits control signaling and / or data; and / or, the second timer is a retransmission timer.

[0275] (3) Determine that the configured DRX configuration does not include the first timer, and / or does not enter the inactive time, and / or the second timer is turned on, and / or enters the active time, and / or the inactive time is stopped.

[0276] (4) Determine whether the first timer is enabled, and / or does not enter the inactive time, and / or the second timer is enabled, and / or enters the active time, and / or the inactive time is stopped;

[0277] In this case, the network-side device can determine whether to enable the first timer. Alternatively, the network-side device can set a first timer for the terminal and enable the first timer.

[0278] (5) Determine whether the first timer is off, and / or does not enter the inactive time, and / or the second timer is on, and / or enters the active time, and / or the inactive time is stopped.

[0279] In this case, the network-side device can determine that the first timer is off by determining that the terminal's first timer is off, or the network-side device can set a first timer for the terminal and determine that the first timer is enabled by the network-side device to disable the network-side device's first timer.

[0280] (6) No target control information is transmitted;

[0281] The fifth sub-case includes one of the following:

[0282] No resources are configured to be reported;

[0283] The reported resources meet the first condition;

[0284] The sixth sub-case includes at least one of the following:

[0285] Sidelink feedback resources have been configured.

[0286] Feedback enables or feedback de-enables.

[0287] In the above possible implementations, the network-side device can perform the second operation when the first time arrives; wherein the first time includes one of the following: a first target time, the sum of the first target time and the first offset time, and the difference between the first target time and the second offset time.

[0288] The first time is the same as or corresponds to the first time in method 200, as can be found in the description in method 200.

[0289] Another possible implementation of S310 is that when the third case is the fifth sub-case and the fourth case is the seventh sub-case, the network-side device performs the second operation;

[0290] The second operation includes one of the following:

[0291] (1) Determine that the first timer is not turned on, and / or determine that the inactive time is not entered, and / or determine that the second timer is turned on, and / or determine that the active time is entered, and / or the inactive time is stopped;

[0292] (2) Determine that the acquired discontinuous reception DRX configuration does not include the first timer, and / or does not enter the inactive time, and / or the second timer is on, and / or enters the active time, and / or the inactive time is stopped;

[0293] (3) Determine whether the first timer is enabled, and / or does not enter the inactive time, and / or the second timer is enabled, and / or enters the active time, and / or the inactive time is stopped;

[0294] (4) Determine whether the first timer is off, and / or does not enter the inactive time, and / or the second timer is on, and / or enters the active time, and / or the inactive time stops;

[0295] (5) Determine whether the first timer is turned on and / or enters the inactive time.

[0296] The meanings of determining whether to start the first timer, not to start the first timer, and to start the second timer are the same as the possible implementation methods mentioned above, and will not be repeated here.

[0297] The fifth sub-case includes one of the following: no reporting resources are configured; or the reporting resources meet the first condition.

[0298] The seventh sub-case includes at least one of the following:

[0299] No sidelink feedback resources are configured or the sidelink feedback resources meet the second condition;

[0300] Feedback enables or feedback de-enables.

[0301] Optionally, in the above possible implementations, the network-side device may perform the second operation at a second time (i.e., when the second time arrives). The second time includes one of the following: a first target time, the sum of the first target time and a third offset time, or the difference between the first target time and a fourth offset time.

[0302] The second time is the same as or corresponds to the second time in method 200, which will not be elaborated here.

[0303] Optionally, the first target time may include at least one of the following:

[0304] (1) Preset the time of the side link DCI; for example, the time of the SL DCI sent by the network-side device.

[0305] (2) Preset transmission time. For example, the time of the Nth transmission (e.g., the first or last transmission) in the license provided by the SL DCI sent by the network-side device. Optionally, this transmission can be PSCCH or a first-stage SCI, such as SCI format 1-A. Alternatively, the transmission can be a second-stage SCI, such as SCI format 2-A or SCI format 2-B. Or the transmission can also be PSSCH.

[0306] (3) Preset the time of the sidelink feedback resource. For example, the time of the sidelink feedback resource corresponding to the Mth transmission (e.g., the first or last transmission) in the license provided by the SL DCI sent by the network-side device, such as the time of the PSFCH corresponding to a certain transmission.

[0307] (4) Preset the start or end time of the side link authorization period. For example, the start or end time of the side link authorization period provided by the SL DCI sent by the network-side device.

[0308] (5) The time when the non-acknowledgment message was received;

[0309] (6) The time of scheduling failure;

[0311] Another possible implementation of S310 is as follows: In the third case, which is the eighth sub-case, the network-side device performs a second operation; wherein the second operation includes at least one of the following:

[0312] (1) Determine when the first timer is turned on and / or determine when to enter the inactive time.

[0313] The meaning of determining to start the first timer is the same as the possible implementation methods mentioned above, and will not be repeated here.

[0314] (2) No target control information is transmitted.

[0315] The eighth sub-case includes: having configured reporting resources or scheduling reporting resources.

[0316] In the above possible implementations, when the third case is the eighth sub-case, the side-link feedback resource can be configured by default, for example, PSFCH can be configured. Alternatively, the second operation described above can be performed when the third case is the eighth sub-case and the fourth case has the side-link feedback resource configured.

[0317] In the above possible implementations, the network-side device can perform the second operation at a third time (i.e., when the third time arrives). The third time includes one of the following: the second target time, the sum of the second target time and the fifth offset time, or the difference between the second target time and the sixth offset time.

[0318] The third time is the same as or corresponds to the third time in method 200, as can be found in the description in method 200.

[0319] In one possible implementation, the second target time includes at least one of the following:

[0320] (1) Preset the start or end time of the side link authorization period. For example, the start or end time of the side link authorization period provided by the SL DCI sent by the network-side device.

[0325] Example 1

[0326] In this embodiment, the UE is not configured with PUCCH or PUSCH, nor is it configured with PSFCH.

[0327] Step 1: When configuring the UE, the base station did not configure PUCCH or PUSCH resources for the UE to report HARQ feedback related to the UE sidelink process.

[0328] Step 2: The base station has not configured PSFCH resources for the UE and / or has not configured any HARQ-enabled logical channels for the UE.

[0329] In practice, the order of steps 1 and 2 is not fixed.

[0330] Step 3, the UE performs at least one of the following actions:

[0331] • HARQ RTT timer not required or HARQ RTT timer not enabled (e.g., HARQ RTT timer disabled); where, not requiring HARQ RTT timer means that HARQ RTT timer is not included in the DRX configuration.

[0332] • Start the retransmission timer at the following time: when the next symbol or slot of the PSFCH sent by the peer UE is received.

[0333] • If the retransmission timer expires, the UE enters sleep mode. For example, at this point, it can be assumed that the base station has no intention of continuing to schedule or schedule retransmissions, and in order to save energy, the UE enters sleep mode.

[0334] Example 2

[0335] In this embodiment, the UE is not configured with PUCCH or PUSCH, but is configured with PSFCH.

[0336] Step 1: The base station did not configure PUCCH or PUSCH resources for the UE to report HARQ feedback related to the UE sidelink process.

[0337] Step 2: The base station configures PSFCH resources for the UE and / or configures at least one HARQ-enabled logical channel for the UE.

[0346] Step 4: The UE starts the retransmission timer after the HARQ RTT timer expires.

[0347] Example 3

[0348] In this embodiment, the UE is not configured with PUCCH or PUSCH, but is configured with PSFCH. The HARQ RTT timer is not started, but a retransmission timer may be started.

[0349] Step 1 is the same as Step 1 in Example 2.

[0350] Step 2 is the same as step 2 in Example 2.

[0351] Step 3 is the same as step 3 in Example 1.

[0352] Example 4

[0353] In this embodiment, the UE is configured with PUCCH, but not with PSFCH.

[0354] Step 1: The base station configures PUCCH or PUSCH resources for the UE to report HARQ feedback related to the UE sidelink process.

[0355] Step 2: The base station has not configured PSFCH resources for the UE, and / or has not configured any HARQ-enabled logical channels for the UE.

[0356] In practice, the order of steps 1 and 2 is not fixed.

[0358] • No HARQ RTT timer required or HARQ RTT timer not enabled.

[0359] • Start the retransmission timer at the following time: when the next symbol or slot of the PSFCH sent by the peer UE is received.

[0360] • If the retransmission timer expires, the UE enters sleep mode. For example, it can be assumed that the base station has no intention of continuing to schedule or schedule retransmissions, therefore, the UE enters sleep mode.

[0361] Example 5

[0362] In this embodiment, the UE is configured with PUCCH and PSFCH, and the UE starts the HARQ RTT timer.

[0363] Step 1: The base station configures PUCCH or PUSCH resources for the UE to report HARQ feedback related to the UE sidelink process.

[0364] Step 2: The base station configures PSFCH resources for the UE and / or configures at least one HARQ-enabled logical channel for the UE.

[0365] In practice, the order of steps 1 and 2 is not fixed.

[0366] Step 3, the UE starts the HARQ RTT timer at the following times:

[0367] • Receive DCI scheduling data transmission from the base station

[0368] • The next symbol or slot of the first SCI was sent.

[0369] • The next symbol or slot of the 2nd SCI was sent.

[0370] • The next symbol or slot of the PSSCH data has been sent.

[0371] • Receive the next symbol or slot of PSFCH sent by the peer UE

[0372] • The next symbol or slot of the HARQ feedback associated with the sidelink process is transmitted on the PUCCH or PUSCH.

[0373] Step 4: The UE starts the retransmission timer after the HARQ RTT timer expires.

[0374] Step 5, optionally, if the network-side device does not actually indicate or schedule PUCCH or PUSCH, or the configured PUCCH is invalid, discarded, or interrupted by other transmissions, the UE performs at least one of the following actions:

[0375] • HARQ RTT timer not required or HARQ RTT timer not enabled

[0376] • Start the retransmission timer at the following time: when the next symbol or slot of the PSFCH sent by the peer UE is received.

[0377] If the retransmission timer times out, the system enters sleep mode. For example, at this point, it can be assumed that the base station has no intention of continuing scheduling or scheduling retransmissions.

[0378] Example 6

[0379] In this embodiment, the UE is configured with PUCCH and PSFCH, and the UE does not start the HARQ RTT timer.

[0380] Step 1: The base station configures PUCCH or PUSCH resources for the UE to report HARQ feedback related to the UE sidelink process.

[0381] Step 2: The base station configures PSFCH resources for the UE and / or configures at least one HARQ-enabled logical channel for the UE.
