Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a discontinuous transmission configuration method and user equipment. Background Technology

[0002] Currently, sidelink systems primarily support two resource allocation modes: scheduled resource allocation (mode-1) and autonomous resource selection (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.

[0003] Since sidelink service requirements typically differ from Uu service requirements, and in Mode-1, users also need to monitor and schedule the DCI (i.e., SL DCI) of sidelink resources, a transmission and feedback process on the sidelink is required before the base station can send the SL DCI to schedule retransmission. Therefore, the SL UE cannot directly reuse the Uu Discontinuous Reception (DRX) mechanism in related technologies. Summary of the Invention

[0004] This invention provides a discontinuous transmission configuration method and user equipment, which can achieve the purpose of configuring discontinuous transmission mode for SL UE.

[0005] To solve the above-mentioned technical problems, the present invention is implemented as follows:

[0006] In a first aspect, embodiments of the present invention provide a discontinuous transmission configuration method, applied to a first UE, the method comprising:

[0007] Obtain target configuration information on at least one carrier; transmit according to the target configuration information; wherein the target configuration information is used to configure a target discontinuous transmission mode, the target discontinuous transmission mode including at least one of a first discontinuous transmission mode and a side link discontinuous transmission mode; wherein the first discontinuous transmission mode is: a Uu discontinuous transmission mode using a side link resource allocation mode.

[0008] Secondly, embodiments of the present invention provide a UE, which is a first UE, comprising: an acquisition module for acquiring target configuration information on at least one carrier; and a transmission module for transmitting information based on the target configuration information acquired by the acquisition module; wherein the target configuration information is used to configure a target discontinuous transmission mode, and the target discontinuous transmission mode includes at least one of a first discontinuous transmission mode and a side-link discontinuous transmission mode; wherein the first discontinuous transmission mode is a Uu discontinuous transmission mode using a side-link resource allocation mode.

[0009] Thirdly, embodiments of the present invention provide a UE, which is a first UE, including a processor, a memory, and a computer program stored in the memory and executable on the processor. When the computer program is executed by the processor, it implements the steps of the discontinuous transmission configuration method as described in the first aspect.

[0010] Fourthly, embodiments of the present invention provide a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the discontinuous transmission configuration method described above.

[0011] In this embodiment of the invention, since the target configuration information obtained by the first UE is used to configure the target discontinuous transmission mode, and the target discontinuous transmission mode includes at least one of the first discontinuous transmission mode (i.e., the Uu discontinuous transmission mode using the side link resource allocation mode) and the side link discontinuous transmission mode, the first UE can configure the target discontinuous transmission mode for itself based on the target configuration information, thereby transmitting in the target discontinuous transmission mode, and thus simultaneously meeting the requirements of the side link service and the Uu service, improving the energy efficiency of the communication system.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] The technical terms involved in the embodiments of the present invention will be explained below.

[0018] 1. Discontinuous transmission

[0019] In this embodiment of the invention, "discontinuous transmission" includes discontinuous reception and / or discontinuous transmission. The aforementioned discontinuous reception refers to "DRX" in related technologies.

[0020] Regarding the "DRX" mechanism in related technologies, both Long Term Evolution (LTE) and NR have introduced DRX mechanisms to achieve UE power saving by configuring the DRX activation and deactivation times. Generally, the on-duration period is the active time of DRX. If no scheduling occurs, the UE will enter a DRX cycle of deactivation after the on-duration period. Typically, DRX configuration involves configuring parameters such as onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimer, and longDRX-CycleStartOffset.

[0021] After DRX is configured, if data decoding fails during transmission or reception, the UE needs to enter the active time listening control channel and wait for network-scheduled retransmission. During On Duration, if the UE is scheduled to receive or transmit data in a slot, it is likely to be scheduled again in the following slots. Therefore, whenever the UE is scheduled to transmit data for the first time, the timer drx-InactivityTimer is started or restarted, and the UE will remain in the active state until the timer expires.

[0022] For downlink data reception, after receiving downlink data transmission indicated by the PDCCH, the UE will start a downlink return timer (HARQRTT (Round Trip Time) Timer) for the corresponding Hybrid Automatic Retransmission (HARQ) process. If the data of the HARQ process is not successfully decoded after the HARQ RTT Timer expires, the UE will start a retransmission timer (drx-RetransmissionTimer) and enter an active state to listen to the PDCCH, waiting for the network to schedule the transmission.

[0023] For uplink data transmission, after receiving the uplink data transmission indicated by the PDCCH, the UE will start the uplink return timer (HARQ RTT Timer) for the corresponding HARQ process. After the HARQ RTT Timer expires, the UE will start the retransmission timer (drx-ULRetransmissionTimer) and enter the active state to listen to the PDCCH, waiting for the network to schedule the transmission.

[0024] 2. Sidelink

[0025] LTE systems support sidelinks, enabling direct data transmission between UEs without relying on network equipment. The UE transmits Sidelink Control Information (SCI) via the Physical Sidelink Control Channel (PSCCH) to schedule transmissions on the Physical Sidelink Shared Channel (PSSCH) to send data. This transmission is broadcast, and the receiving end does not report back to the sending end whether reception was successful.

[0026] The LTE sidelink design supports two resource allocation modes: Scheduled resource allocation (often referred to as mode-1) and autonomous resource election. In the former, the network-side equipment controls and allocates resources to each UE, while in the latter, the UE autonomously selects resources.

[0027] 3. Sidelink Feedback

[0028] Sidelink feedback refers to receiving or sending sidelink HARQ-ACK on the sidelink.

[0029] Taking the TX UE as an example, the TX UE sends a signal to the RX UE on the sidelink. The RX UE receives the signal and sends a sidelink HARQ-ACK back to the TX UE on the PSFCH. Then, the TX UE reports the sidelink HARQ-ACK to the base station. The period of the PSFCH is N, where N = 1, 2, or 4 logical slots (sidelink slots). The actual distance between the N sidelink slots may be greater than the duration of the slots corresponding to the N physical slots.

[0030] Assuming that physical slots 2 and 4 out of 5 physical slots are used for SL, then the logical slot numbers of these two SL slots, or in other words, the SL slot numbers are 1 and 2. In this case, the actual distance between logical slots 1 and 2 is 2 physical slots, which is greater than the duration corresponding to 1 slot.

[0031] 4. Other terms

[0032] It should be noted that the " / " in this article means "or". For example, A / B can mean A or B. The "and / or" in this article is only a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone.

[0033] It should be noted that, in order to clearly describe the technical solutions of the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish the same or similar items with essentially the same function or role. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order. For example, "first UE" and "second UE" are used to distinguish different UEs, rather than to describe a specific order of UEs.

[0034] It should be noted that in the embodiments of the present invention, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of the present invention should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0035] It should be noted that in the embodiments of this application, "of", "corresponding", and "corresponding" can sometimes be used interchangeably. It should be pointed out that when their distinction is not emphasized, their intended meanings are consistent. In the embodiments of this application, "multiple" means two or more.

[0036] The solutions provided by the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0037] The technical solution provided by this invention can be applied to various communication systems, such as 5G communication systems, future evolution systems, or multiple communication convergence systems. It can include various application scenarios, such as machine-to-machine (M2M), direct-to-machine (D2M), macro-micro communication, enhanced mobile broadband (eMBB), ultra-reliable and low-latency communication (uRLLC), and massive machine-type communication (mMTC). These scenarios include, but are not limited to, communication between UEs, communication between network-side devices, or communication between network-side devices and UEs. The embodiments of this invention can be applied to communication between network-side devices and UEs in 5G communication systems, or communication between UEs, or communication between network-side devices.

[0038] Figure 1 A possible structural schematic diagram of a communication system according to an embodiment of the present invention is shown. For example... Figure 1 As shown, the communication system includes at least one network-side device 100. Figure 1 (Only one is shown in the image) and one or more UE200s connected to each network-side device 100.

[0039] The network-side device 100 mentioned above can be a base station, core network equipment, transmission and reception point (TRP), relay station, or access point, etc. The network-side device 100 can be a base transceiver station (BTS) in a Global System for Mobile communication (GSM) or Code Division Multiple Access (CDMA) network, an NB (NodeB) in Wideband Code Division Multiple Access (WCDMA), or an eNB or eNodeB (evolutionary NodeB) in LTE. The network-side device 100 can also be a radio controller in a Cloud Radio Access Network (CRAN) scenario. The network-side device 100 can also be a network-side device in a 5G communication system or a network-side device in a future evolved network. However, the terminology used does not constitute a limitation of the present invention.

[0040] UE200 can be a terminal device, which can be a wireless terminal device or a wired terminal device. The wireless terminal device can be a device that provides voice and / or other service data connectivity to the user, such as a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a future 5G network, or a terminal device in a future evolved PLMN network, etc. Wireless terminal equipment can communicate with one or more core networks via a Radio Access Network (RAN). Wireless terminal equipment can be mobile terminal equipment, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, for example, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices. They exchange voice and / or data with the RAN, and include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), etc. Wireless terminal equipment can also be mobile devices, User Equipment (UE), UE terminal equipment, access terminal equipment, wireless communication equipment, terminal equipment units, terminal equipment stations, mobile stations, mobile stations, remote stations, remote terminals, subscriber units, subscriber stations, and user agents. Agent), terminal equipment, etc. As an example, in an embodiment of the present invention, Figure 1 Let's take a mobile phone as an example to illustrate this.

[0041] The solution provided in this embodiment of the invention is applicable to scenarios where the UE sends feedback information to the network-side device, and to scenarios where the UE sends feedback information to the network-side device.

[0042] Figure 2 The following is a flowchart illustrating a discontinuous transmission configuration method provided by an embodiment of the present invention, as shown in the figure. Figure 2 As shown, the information reporting method may include:

[0043] Step 201: The first UE obtains target configuration information on at least one carrier.

[0044] Step 202: The first UE transmits according to the target configuration information.

[0045] In this embodiment of the invention, the target configuration information is used to configure a target discontinuous transmission mode; the target discontinuous transmission mode includes at least one of a first discontinuous transmission mode and a side link discontinuous transmission mode; wherein, the first discontinuous transmission mode is a Uu discontinuous transmission mode using a side link resource allocation mode.

[0046] It should be noted that the aforementioned Uu discontinuous transmission mode refers to the discontinuous transmission mode used for the Uu PDCCH; the aforementioned Uu refers to the Uu interface between the UE and the network-side equipment. The aforementioned first Uu discontinuous transmission mode refers to the Uu discontinuous transmission mode of the first UE using the sidelink resource allocation mode. The Uu interface of the first UE using the sidelink resource allocation mode can be considered as the Uu interface scheduled under the sidelink. Therefore, the aforementioned first Uu discontinuous transmission mode can be simply referred to as the scheduled Uu discontinuous transmission mode. The aforementioned sidelink discontinuous transmission mode refers to the discontinuous transmission mode used on the sidelink.

[0047] For example, the above-mentioned side link resource allocation mode can be the mode1 mode under the side link, or it can be a derived mode when other network-side devices schedule side links. This embodiment of the invention does not limit this.

[0048] Optionally, in this embodiment of the invention, if the target configuration information is the configuration information for the scheduled Uu discontinuous transmission mode, then the carrier is a Uu carrier; if the target configuration information is the configuration information for the side link discontinuous transmission mode, then the carrier is a side link carrier.

[0049] Optionally, in this embodiment of the invention, the target configuration information is configured by the network-side device for the first UE, or it is specified by the protocol, or it is pre-configured, or it is indicated by the second UE, or it is negotiated between the UEs.

[0050] Optionally, in this embodiment of the invention, the target configuration information is carried on at least one of the following signaling: configuration signaling for Uu discontinuous transmission mode, configuration signaling for the first discontinuous transmission mode, and configuration signaling for the side-link discontinuous transmission mode. For example, if the target configuration information is carried on configuration signaling for Uu discontinuous transmission mode, it can be considered that the configuration signaling corresponding to Uu discontinuous transmission mode in the related art includes configuration information for the first discontinuous transmission mode or configuration information for the side-link discontinuous transmission mode. That is, it can be considered that at least a portion of the Uu discontinuous transmission mode in the related art is reused.

[0051] Optionally, in this embodiment of the invention, the target configuration information includes at least one of the following: at least one retransmission timer (i.e., RTT timer) and at least one retransmission timer (i.e., retransmission timer). It should be noted that the retransmission may involve retransmitting or receiving the same TB (transport block).

[0052] For example, the target configuration information described above is used to configure one or more RTT timers, and / or, the target configuration information is also used to configure one or more retransmission timers. The timing durations of the multiple RTT timers can be the same or different. Similarly, the timing durations of the multiple retransmission timers can be the same or different, depending on the actual usage requirements. This embodiment of the invention does not impose any limitations on this.

[0053] For example, the first UE can use a configured timer, or it can configure a deterministic timer, or it can dynamically determine the timer according to the actual scheduling. Specifically, it can be determined according to the actual usage requirements, and the embodiments of the present invention do not limit this.

[0054] Optionally, the timing period of the timer in this embodiment of the invention is logical time or physical time.

[0055] Optionally, in this embodiment of the invention, the target configuration information is used to configure at least one of a wait-for-retransmission timer and a retransmission timer for each or each group of target objects; wherein, the target objects include at least one of the following: carrier, bandwidth part (BWP), resource pool, link, transmission, feedback mechanism, sidelink HARQ process, downlink HARQ process, sidelink grant, destination ID, and source ID.

[0056] For example, the aforementioned links can be higher-level signaling links (e.g., PC5 RRC connections, sidelink RRC links, or service links) or transport links, such as multicast, unicast, or broadcast. It should be noted that multicast does not necessarily imply the existence of a signaling link. Specifically, at least one of a wait-for-retransmission timer and a retransmission timer can be configured for each or each group of link IDs.

[0057] For example, the above sidelink grant includes: configured sidelink grant and / or dynamic sidelink grant, wherein the above dynamic sidelink grant can be downlink control information (DCI) (SL DCI) for scheduling sidelink resources.

[0058] It should be noted that the aforementioned scheduling of sidelink resources is a generalized scheduling approach. For example, the aforementioned scheduling of sidelink resources may include: scheduling sidelink transmissions, activating sidelink resources, or deactivating sidelink resources.

[0059] It should be noted that the embodiments of the present invention can be configured with one or more RTT timers and one or more retransmission timers. For example, three RTT timers can be configured for a HARQ process, corresponding to transmission counts of 1, 2, and 3 respectively. The user determines which of the three to use based on the dynamically scheduled transmission count.

[0060] Optionally, in this embodiment of the invention, the aforementioned wait-for-retransmission timer is a first wait-for-retransmission timer, and / or, the aforementioned retransmission timer is at least one of the first retransmission timers; wherein, the aforementioned first wait-for-retransmission timer and the first retransmission timer are timers corresponding to the aforementioned first discontinuous transmission mode. The aforementioned first wait-for-retransmission timer can be a wait-for-SL bs-scheduled HARQ retransmission timer (abbreviated as SL bs-scheduled RTT timer), for example, drx-HARQ-RTT-TimerSL-bs-scheduled. The aforementioned first retransmission timer can be an SL bs-scheduled retransmission timer (abbreviated as SL bs-scheduled Re timer), for example, drx-RetransmissionTimerSL-bs-scheduled.

[0061] It should be noted that, since the sidelink service and the Uu service are different, the aforementioned first wait-for-retransmission timer and first retransmission timer will be different from the timers of the uplink UL and downlink DL. Moreover, the timing of the sidelink needs to take into account the latency of sidelink transmission, sidelink feedback and reporting to the base station, so it is very likely to be longer than the timer corresponding to Uu.

[0062] For example, in the first discontinuous transmission mode, when the SL TB transmission of a sidelink HARQ process fails in mode-1, the UE can assume that the base station will not send the SL DCI to schedule retransmission until at least after the "wait for SL mode-1 HARQ retransmission timer (i.e., the aforementioned first wait for retransmission timer)" expires. Therefore, when the aforementioned "wait for SL mode-1 HARQ retransmission timer" is running, the UE does not need to listen to the SL DCI. When the "wait for SL mode-1 HARQ retransmission timer" times out and the data of the corresponding sidelink HARQ process is not successfully decoded, the UE will start an "SL mode-1 retransmission timer (i.e., the aforementioned first retransmission timer)" for that HARQ process. When the "SL mode-1 retransmission timer" is running, the UE will listen to the SL DCI used for sidelink HARQ retransmission. This requires the base station to schedule sidelink HARQ retransmission and allocate radio resources for it after the "SL mode-1 retransmission timer" times out. In this way, the combination of the above two timers can save power consumption.

[0063] Optionally, in embodiments of the present invention, the timing of the retransmission waiting timer and / or the timing of the retransmission timer are related to at least one of the following:

[0064] Carrier, BWP, resource pool, transmission type, feedback mechanism, maximum number of transmissions on the sidelink grant, number of resources on the aforementioned sidelink grant, actual number of transmissions on the aforementioned sidelink grant, minimum time interval K between the physical sidelink feedback channel (PSFCH) and the corresponding physical sidelink shared channel (PSSCH) corresponding to the sidelink resource, transmission period N of the PSFCH corresponding to the aforementioned sidelink resource, maximum number of transmissions scheduled by SCI, actual number of transmissions scheduled by the aforementioned SCI, maximum number of retransmissions, resource preemption parameters, priority, communication distance, delay, reliability, channel busy ratio (CBR), channel occupancy ratio (CR), time range occupied by the aforementioned sidelink resource, sidelink resource configuration information, sidelink resource indication information, physical uplink control channel (PUCCH) configuration information, and PUCCH indication information.

[0065] For example, the target configuration information described above can configure one or more wait-for-retransmission timers, and / or one or more retransmission timers. The duration of each timer is related to one or more of the above parameters; that is, the durations of the one or more wait-for-retransmission timers can be the same or different. Similarly, the durations of the one or more retransmission timers can be the same or different. In one embodiment, the duration of the timers can be determined based on the resource pool configuration. For example, suppose that an RTT timer is configured for each harq process, and the duration of the RTT timer is related to the PSFCH period in the resource pool. Suppose that the PSFCH periods of resource pools 1 and 2 are 2 and 4 respectively. When using the harq process to transmit in resource pool 1, the length of the timer will be different from when using the harq process to transmit in resource pool 2; that is, the timer length will change accordingly.

[0066] For example, the above transmission types include broadcast, multicast, or unicast.

[0067] For example, the above feedback mechanism includes two types: no feedback and feedback required. Feedback required is further divided into option 1 (feedback without connection) and option 2 (feedback with connection). For option 1, a NACK is sent if decoding fails; for option 2, an ACK is sent if successful, and a NACK is sent if unsuccessful. For example, broadcasting does not require sidelink feedback; in this case, the timer may be shorter than the timer for transmissions that require sidelink feedback.

[0068] For example, the resource pool where the scheduling resource pool or the resource pool where the side link authorization is located is related to the resource pool because many transmission parameters, such as K, N, the maximum number of transmissions Nmax on the side link authorization, and the maximum number of retransmissions, are configured separately for each resource pool. For instance, taking two resource pools (resource pool 1 and resource pool 2) as an example, each resource pool is configured with an RTT timer. The RTT timer is related to Nmax. When Nmax = 2 for resource pool 1 and Nmax = 3 for resource pool 2, the two timers corresponding to the two resource pools have different lengths.

[0069] For example, the number of transmissions mentioned above can be the number of data transmissions or the number of transmissions of other signals besides data (such as reference signal RS, sequence, control signaling, etc.).

[0070] For example, the maximum number of retransmissions + 1 is the maximum number of transmissions.

[0071] For example, the number of transmissions actually scheduled by an SCI can be considered as the number of resources contained in that SCI.

[0072] For example, the above-mentioned sidelink resource configuration information may include configuration information of at least one of PSCCH, PSSCH and PSFCH.

[0073] For example, the above sidelink resource configuration information may also include: SL DCI indication, or SCI indication, or sidelink configured grant configuration, etc.

[0074] For example, the resource preemption parameters described above can be used to indicate at least one of the following: number of preemptions, number of times preempted, maximum number of times preempted, and maximum number of preemptions. For instance, a larger number of preemptions corresponds to a larger timer; or a smaller number of times preempted corresponds to a smaller timer.

[0075] For example, the higher the priority, the shorter the timer, and vice versa; or, the higher the priority, the longer the timer, and vice versa.

[0076] For example, the greater the required communication distance, the longer the timer; conversely, the smaller the required communication distance, the shorter the timer; or, the smaller the required communication distance, the longer the timer, and the greater the required communication distance, the shorter the timer.

[0077] For example, the shorter the latency requirement, the shorter the timer; conversely, the longer the latency requirement, the longer the timer.

[0078] For example, the higher the reliability requirement, the longer the timer, and vice versa; or, the higher the reliability requirement, the shorter the timer, and vice versa.

[0079] For example, the higher the CBR, the longer the timer, and vice versa; or, the higher the CBR, the shorter the timer, and vice versa.

[0080] For example, the higher the CR, the longer the timer, and vice versa; or, the higher the CR, the shorter the timer, and vice versa.

[0081] For example, taking the SL bs-scheduled Re timer as an example, each SL bs-scheduled Re timer is related to at least one of the following: the maximum number of transmissions Nmax scheduled by K, N, SL DCI, the actual number of SL transmissions Nactual scheduled by SL DCI, the maximum number of transmissions Nmax_SCI scheduled by SCI, the actual number of transmissions Nactual_SCI scheduled by SCI, and the maximum number of retransmissions N_retx.

[0082] Optionally, in this embodiment of the invention, the time range occupied by the side link resources is W time slots, milliseconds, or subframes; or, the time range occupied by the side link resources is related to the maximum number of transmissions on the side link grant; or, the time range occupied by the side link resources is the actual time resource span occupied by transmissions on the side link grant; or, the time range occupied by the side link resources is related to the maximum number of transmissions scheduled by the SCI; or, the time range occupied by the side link resources is the time resource span occupied by resources actually scheduled by the SCI; wherein, W is a preset value.

[0083] For example, the time range occupied by the aforementioned sidelink resources can be 32 slots.

[0084] For example, the time range occupied by the aforementioned sidelink resources can be related to the maximum number of transmissions Nmax scheduled by the SL DCI. For instance, when Nmax = 2, the time range occupied by the sidelink resources is equal to the preset value 1; when Nmax = 3, the time range occupied by the sidelink resources is equal to the preset value 2. It should be noted that the preset values ​​1 and 2 can be pre-configured or pre-defined.

[0085] For example, consider the time range occupied by the aforementioned sidelink resources and the span between the time resources occupied by the sidelink transmissions actually scheduled by the SL DCI. In one example, the SL DCI actually schedules 3 resources, and these 3 resources are located in slot 1, slot 2, and slot 5 respectively. Then, the value of the time range occupied by the SL resources is 5 - 1 + 1 = 5 slots. In this case, the value of Timer will change according to the actual situation of each scheduling.

[0086] Optionally, in this embodiment of the invention, the duration of the first retransmission timer corresponding to the first discontinuous transmission mode is not less than any of the following: the duration from the time of the side link grant to the time when the user sends the corresponding PUCCH, or the duration from the time of the activation signaling corresponding to the side link grant to the time when the user sends the corresponding PUCCH, or the duration from the time of the first or last transmission of the side link grant to the time when the user sends the corresponding PUCCH, or the duration from the time of the PSFCH corresponding to the first or last transmission of the side link grant to the time when the user sends the corresponding PUCCH.

[0087] For example, the duration of the first waiting retransmission timer is greater than or equal to y1 + the time range occupied by the side link resources + K + N-1 + y2, or the duration of the first waiting retransmission timer is greater than or equal to y1 + the time range occupied by the side link resources + K + y2, or the duration of the first waiting retransmission timer is greater than or equal to y2.

[0088] Wherein, K is the minimum time interval between the PSFCH and PSSCH corresponding to the side link resource, N is the transmission period of the PSFCH corresponding to the side link resource, y1 is the time interval between the side link grant and the first side link resource allocated thereto, and y2 is the time interval between the PSFCH and PUCCH corresponding to the last side link resource allocated by the side link grant.

[0089] For example, the duration of the first retransmission waiting timer is greater than or equal to y1 + the time range occupied by the side link resources + the preset interval M + y2. In one example, the preset interval M can be the interval between the last PSSCH and its corresponding interval or the maximum interval. It should be noted that M can be a preset value or a value determined according to actual usage requirements, and this embodiment of the invention does not limit it. For example, the maximum value of M can be K + N - 1, and the minimum value of M can be K.

[0090] For example, if y1 = 1, y2 = 1, N = 2, and K = 2, the duration of the first retransmission timer may be 1 + 1 + 2 + 2 = 6 slots. Optionally, the user may wait at least 6 slots before continuing to monitor the SL DCI.

[0091] For example, for a TX UE, specifically in the case of SL DCI scheduling TX UE transmission, if the TX UE sends a sidelink HARQ-ACK, then the duration of the aforementioned first retransmission waiting timer must at least include: the time occupied by the process of SL DCI -> TX UE transmitting SL -> RX UE PSFCH -> TX UE sending PUCCH -> gNB. For instance, the duration of the SL bs-scheduledRTT timer is >= y1 + the time range occupied by the sidelink resources + K + N-1 + y2.

[0092] In one example, the above process of SL DCI->TX UE transmission SL->RX UE PSFCH->TX UE sending PUCCH->gNB includes: starting from the TX UE receiving the SL DCI, the TX UE performs SL transmission according to the SL DCI (sending PSSCH and PSCCH), the RX UE receives the transmission and sends PSFCH as feedback, the TX UE receives the PSFCH and determines to send feedback information, and then sends it to the base station on the PUCCH.

[0093] In one example, for the case of SL DCI scheduling TX UE transmission, if an SL DCI indicating initial transmission is received, it means that it is unlikely that a new SL DCI scheduling indication sidelink will be sent in the near future. In this case, the user enables the SL bs-scheduled RTT timer, and the user can stop monitoring the SL DCI in the SL bs-scheduled RTT timer.

[0094] For example, for an RX UE, specifically in the case of SL DCI scheduling for RX UE reception, if the RX UE sends a sidelink HARQ-ACK, then the duration of the first retransmission timer mentioned above must at least include: the time occupied by the process of SL DCI -> RX receiving the SL transmission corresponding to SL DCI -> RX UE sending PSFCH -> RX UE PUCCH -> Gnb. For example, the duration of the SLbs-scheduled RTT timer is >= y1 + the time range occupied by the sidelink resources + K + N-1 + y2.

[0095] In one example, the process of SL DCI->RX receiving all SL->RX UE PSFCH->RX UE PUCCH->Gnb includes: receiving SL DCI from RX UE, RX UE performing SL transmission based on SL DCI (e.g., receiving PSSCH and PSCCH), determining feedback information, and then sending it to the base station on PUCCH.

[0096] In one example, for the case of SL DCI scheduling RX UE reception, if an SL DCI indicating initial transmission is received, it means that it is unlikely that there will be a new SL DCI scheduling indication to receive sidelink transmission in the near future. In this case, the user starts the SL bs-scheduled RTT timer, and the user can stop monitoring the SL DCI within the SL bs-scheduled RTT timer (optionally, this scheme is applicable when both TX UE and RX UE are bs-scheduled).

[0097] For example, if the above SL bs-scheduledRTT timer is started at the last transmission of the side link scheduling, then the duration of the above SL bs-scheduled RTT timer is >= K+N-1+y2.

[0098] For example, if the above-mentioned SL bs-scheduled RTT timer is started at the time corresponding to the PSFCH of the last transmission in the side link scheduling, then the duration of the above-mentioned SL bs-scheduled RTT timer is >= y2.

[0099] Optionally, in this embodiment of the invention, the discontinuous transmission configuration method further includes the following steps:

[0100] Step A: Upon receiving the SL DCI, or at the time of the first or last transmission of the aforementioned side link authorization, or at the time of the PSFCH corresponding to the first or last transmission of the aforementioned side link authorization, or when the first UE fails to transmit, the first UE starts a retransmission waiting timer according to the target configuration information.

[0101] For example, the above-mentioned first UE transmission failure includes: the first UE receiving failure, or the first UE sending failure, or the first UE not receiving the corresponding transmission success feedback (e.g., ACK), or the first UE not sending the corresponding transmission success feedback (e.g., ACK).

[0102] Optionally, in this embodiment of the invention, the discontinuous transmission configuration method further includes the following steps:

[0103] Step B: After the first retransmission timer is started, the first UE monitors the PDCCH.

[0104] Further optionally, in this embodiment of the invention, step B may include the following steps:

[0105] Step B1: After the first retransmission timer is started, the first UE monitors the SL DCI.

[0106] Optionally, in this embodiment of the invention, the target configuration information includes at least one of the following: an activated timer, information on the discontinuous transmission period of the target discontinuous transmission mode, and offset information on the discontinuous transmission period of the target discontinuous transmission mode.

[0107] For example, for the first discontinuous transmission mode (i.e., bs-scheduled Uu discontinuous transmission mode) or the side-link discontinuous transmission mode (i.e., SL discontinuous transmission mode), taking DRX as an example, the above target configuration information configuration includes at least one of the following:

[0108] drx-onDurationTimerSL-bs-scheduled or drx-onDurationTimer-SL,

[0109] drx-InactivityTimerSL-bs-scheduled or drx-InactivityTimer-SL,

[0110] drxShortCycleTimerSL-bs-scheduled or drxShortCycleTimer-SL,

[0111] drx-LongCycleStartOffsetSL-bs-scheduled or drx-LongCycleStartOffset-SL,

[0112] drx-ShortCycleSL-bs-scheduled or drx-ShortCycle-SL,

[0113] drx-SlotOffsetSL-bs-scheduled or drx-SlotOffset-SL.

[0114] Among them, drx-SlotOffsetSL-bs-scheduled or drx-SlotOffset-SL is the activation timer, offset or period of the bs-scheduled Uu non-continuous transmission mode or the side link non-continuous transmission mode.

[0115] Among them, drx-HARQ-RTT-Timer is the DRX-wait-retransmission timer, drx-RetransmissionTimer is the DRX-retransmission timer, drx-onDurationTimer is the DRX-onDuration timer, drx-InactivityTimer is the DRX-inactivity timer, and drxShortCycleTimer is the DRX-short-cycle timer. A suffix of -SL indicates a timer for SL DRX, and a suffix of SL-bs-scheduled indicates a counter for the first discontinuous transmission mode.

[0116] Optionally, in this embodiment of the invention, each of the at least one carrier is configured with a different discontinuous transmission mode, or the at least one carrier is configured with the same discontinuous transmission configuration. For example, each carrier may be configured with a set of discontinuous transmission configurations, or only the primary carrier component (PCC) or the synchronization carrier (Synchronization CC) may be configured with discontinuous transmission configurations. The synchronization carrier may be the carrier containing the synchronization reference, a carrier capable of receiving synchronization signals, or a carrier capable of transmitting synchronization signals.

[0117] Further optionally, in embodiments of the present invention, when the at least one carrier includes at least two carriers, the following at least one piece of information is the same in the discontinuous transmission modes configured for the at least two carriers respectively: the duration of the working time in the activation time (i.e., the on duration is a part of the activation time), and the starting point of the working time. For example, M carriers are configured, and the discontinuous transmission of N carriers among the M carriers is aligned, where N <= M.

[0118] Optionally, in this embodiment of the invention, the activation time of the target discontinuous transmission mode includes the timing duration of the retransmission timer.

[0119] For example, when SL DRX mode is configured, the meaning of activation time includes any of the following:

[0120] 1) The timing interval of the SL bs-scheduled retransmission timer or the timing interval of a running SL bs-scheduled retransmission timer (e.g., drx-RetransmissionTimerSL-bs-scheduled).

[0121] For example, when the bs-scheduled Uu DRX mode is configured, the active time or SL bs-scheduledDRX active time includes the time of at least one of the following: (currently running) drx-onDurationTimerSL-bs-scheduled, drx-InactivityTimerSL-bs-scheduled, drx-RetransmissionTimerSL-bs-scheduled, and ra-ContentionResolutionTimerSL-bs-scheduled.

[0122] For example, embodiments of the present invention may also define the sidelink bs-scheduled DRX active time, which includes the time of the (running) SL bs-scheduled retransmission timer (drx-RetransmissionTimerSL-bs-scheduled).

[0123] It should be noted that the network-side device may not be aware of this definition. Therefore, the network-side device may still send SL DCI to the first UE at this time. The first UE cannot enable the SL DCI RTT timer, which is different from the UuDRX mode in related technologies.

[0124] Optionally, in this embodiment of the invention, when the target discontinuous transmission mode is the first discontinuous transmission mode, the method provided by this embodiment of the invention may further include the following steps:

[0125] Step 202a: If the first condition is met, then according to the target configuration information, use at least one of the timers corresponding to the first discontinuous transmission mode and the timers corresponding to the above-mentioned Uu discontinuous transmission mode; and / or, if the first wait-for-retransmission timer times out, then according to the target configuration information, start the first retransmission timer; and / or, if the second condition is met, then according to the target configuration information, start or restart the activation timer.

[0126] The timers corresponding to the first discontinuous transmission mode include at least one of the following: a first retransmission wait timer and a first retransmission timer. The timers corresponding to the Uu discontinuous transmission mode include at least one of the following: a second retransmission wait timer and a second retransmission timer. The first condition includes any one of the following: a third condition and at least one of the first UE receiving a first SL DCI, wherein the first UE receives or transmits information on one or more configured sidelink grants. The second condition includes any one of the following: a third condition and at least one of the first UE receiving a second DCI.

[0127] For example, the timer corresponding to the Uu discontinuous transmission mode mentioned above can be a timer that is reused from the Uu discontinuous transmission mode.

[0128] For example, the third condition mentioned above includes: the first UE monitors the PDCCH.

[0129] In one example, the aforementioned monitoring of the PDCCH by the first UE includes: the first UE monitoring the PDCCH during the active time of the first discontinuous transmission mode, and / or, the first UE monitoring the PDCCH scrambled by the sidelink RNTI. In another possible example, the aforementioned monitoring of the PDCCH by the UE includes: the first UE monitoring the PDCCH scrambled by the sidelink RNTI during the active time of the sidelink discontinuous transmission mode.

[0130] For example, the resource indicated by the first DCI mentioned above is used for non-initial transmission.

[0131] For example, the second DCI indicates the activation or deactivation of a sidelink resource; or, the resources indicated by the second DCI include at least the resources used for initial transmission. In one example, the resources indicated by the second DCI include at least the resources used for initial transmission, and the resources indicated by the second DCI are also used to indicate the activation of a sidelink resource.

[0132] Further optionally, in this embodiment of the invention, the timer corresponding to the first discontinuous transmission mode includes at least one of the following: enabling the first retransmission waiting timer and disabling the first retransmission timer; and / or, reusing the timer corresponding to the Uu discontinuous transmission mode includes at least one of the following: enabling the second retransmission waiting timer and disabling the second retransmission timer.

[0133] Further optionally, in this embodiment of the invention, when the first UE receives or sends information on a configured sidelink license, starting the second retransmission timer includes: delaying the first predetermined time or offsetting the first offset before starting the second retransmission timer; and / or, closing the second retransmission timer includes: delaying the second predetermined time or offsetting the second offset before closing the second retransmission timer.

[0134] Further optionally, in this embodiment of the invention, when the first UE receives the first DCI, starting the second retransmission timer includes: delaying for a third predetermined time or offsetting by a third offset before starting the second retransmission timer; and / or, stopping the second retransmission timer includes: delaying for a fourth predetermined time or offsetting by a fourth offset before stopping the second retransmission timer.

[0135] Further optionally, in the embodiments of the present invention, the first predetermined time, the first offset, the second predetermined time, the second offset, the third predetermined time, the third offset, the fourth predetermined time, and the fourth offset may be pre-configured, or may be specified by the protocol, or may be predefined. Specifically, they can be set according to actual needs, and the embodiments of the present invention do not limit them in this regard.

[0136] Further optionally, in this embodiment of the invention, activating the target retransmission timer includes: activating the target retransmission timer for the target object corresponding to the target waiting retransmission timer; wherein the target object includes at least one of the following: BWP, resource pool, link, transmission, feedback mechanism, sidelink HARQ process, downlink HARQ process, sidelink authorization, destination ID, and source ID. The target retransmission timer is a first retransmission timer, and the target waiting timer is a first waiting retransmission timer; or, the target retransmission timer is a second retransmission timer, and the target waiting timer is a second waiting retransmission timer.

[0137] For example, after the first wait-for-retransmission timer expires, the first symbol of the first wait-for-retransmission timer expires is the target object corresponding to the first wait-for-retransmission timer, and the corresponding first retransmission timer is started.

[0138] For example, when the first UE receives or sends information on the configured sidelink authorization, the user behavior of the first UE includes:

[0139] 1) Use at least one of the first wait-for-retransmission timer and the first retransmission timer.

[0140] A) Enable the waiting timer for SL bs-scheduled HARQ retransmission (e.g., drx-HARQ-RTT-TimerSL-bs-scheduled), which is the first waiting timer mentioned above.

[0141] For example, start the SL bs-scheduled HARQ retransmission timer corresponding to the target object of the sidelink transmission.

[0142] B) Disable the SL bs-scheduled retransmission timer (e.g., drx-RetransmissionTimerSL-bs-scheduled), which is the first retransmission timer mentioned above.

[0143] 2. Reuse the existing timers corresponding to Uu discontinuous transmission.

[0144] A) Start the Uu HARQ retransmission timer.

[0145] For example, a delay of delta1 or an offset of offset1 can be used to enable a wait timer for HARQ retransmission (e.g., drx-HARQ-RTT-TimerUL).

[0146] B) Disable the Uu retransmission timer

[0147] For example, delaying the time by delta2 or offsetting by offset2 disables the Uu retransmission timer (e.g., drx-RetransmissionTimerUL).

[0148] For example, disable the SL bs-scheduled retransmission timer corresponding to the target object being transmitted by this sidelink.

[0149] For example, if the first SL DCI is received, the user action of the first UE includes: starting or restarting drx-InactivityTimer. For example, starting or restarting drx-InactivityTimer on the first symbol after receiving the first SL DCI (the last symbol).

[0150] For example, if the first SL DCI is received, the user behavior of the first UE includes at least one of the following:

[0151] 1) Use at least one of the first wait-for-retransmission timer and the first retransmission timer;

[0152] A) Start the SL bs-scheduled HARQ retransmission timer (e.g., drx-HARQ-RTT-TimerSL-bs-scheduled). For example, start the corresponding SLbs-scheduled HARQ retransmission timer for the target object corresponding to the first SL DCI (see explanation above). For example, if the first SL DCI indicates HARQ process id = 1, start the corresponding SLbs-scheduled HARQ retransmission timer for HARQ process #1 after the first SL transmission (last symbol) scheduled by the first SLDCI.

[0153] B) Stop the SL bs-scheduled retransmission timer (e.g., drx-RetransmissionTimerSL-bs-scheduled). For example, stop the SL bs-scheduled retransmission timer corresponding to the target object corresponding to the first SL DCI. For example, if the first SL DCI indicates HARQ process id=1, stop the SL bs-scheduled retransmission timer for HARQ process id#1.

[0154] 2) Reuse the timer corresponding to the Uu discontinuous transmission mode;

[0155] A) Enable the Uu HARQ retransmission timer (e.g., drx-HARQ-RTT-TimerUL).

[0156] For example, delaying time delta3 or offset offset3 enables waiting for drx-HARQ-RTT-TimerUL.

[0157] B) Disable the Uu retransmission timer (e.g., drx-RetransmissionTimerUL).

[0158] For example, delaying the time by delta4 or offsetting by offset4 disables drx-RetransmissionTimerUL.

[0159] Optionally, in this embodiment of the invention, when the target discontinuous transmission mode includes a first discontinuous transmission mode or a side-link discontinuous transmission mode, the solution provided by this embodiment of the invention further includes the following step C:

[0160] Step C: Perform at least one of the following operations:

[0161] Sidelink channel state information (CSI) measurements are performed during the first active time of the target discontinuous transmission mode.

[0162] When a sidelink CSI-RS for channel measurement and / or a CSI-IM for interference measurement are received during or no later than the second activation time of the target discontinuous transmission mode, a sidelink CSI report shall be submitted.

[0163] The sidelink CSI-RS during the active time of the target discontinuous transmission mode is measured.

[0164] It is expected / believed / assumed that there are no sidelink CSI-RS outside the activation time of the target discontinuous transmission mode.

[0165] The first activation time is the activation time when the CSI report for the side link is reported; the second activation time is the activation time when the CSI reference resource is received.

[0166] Further optionally, in this embodiment of the invention, when the sidelink CSI-RS for channel measurement and / or the CSI-IM for interference measurement are received during or no later than the second activation time of the target discontinuous transmission mode, the first UE reports a sidelink CSI report; otherwise, the sidelink CSI report is discarded.

[0167] Further optionally, in this embodiment of the invention, the activation time of the target discontinuous transmission mode is the combination or intersection of the activation time of the side link discontinuous transmission mode and the activation time of the Uu discontinuous transmission mode; or, the activation time of the target discontinuous transmission mode is the combination or intersection of the activation time of the first discontinuous transmission mode and the activation time of the Uu discontinuous transmission mode.

[0168] Optionally, in this embodiment of the invention, if the first UE uses the first transmission resource, or regardless of whether the first UE uses the target transmission resource, the working state of the first UE remains unchanged.

[0169] Optionally, in this embodiment of the invention, if the first UE uses the target transmission resource, or regardless of whether the first UE uses the target transmission resource, the target transmission resource is in an active time, or the first UE is in an active time on the target transmission resource.

[0170] The aforementioned target transmission resource is at least one transmission resource authorized by the side link.

[0171] For example, taking at least one transmission resource of the configured sidelink grant as an example, when the first UE is in an active state (i.e., the activation time includes the configured sidelink grant), if the first UE actually uses at least one transmission resource of the configured sidelink grant for transmission, the first UE is still in an active state; or, regardless of whether the first UE actually uses at least one transmission resource of the configured sidelink grant for transmission, the first UE is in an active state, and if an RTT Timer is running, the RTT Timer is turned off.

[0172] Optionally, in this embodiment of the invention, the information reporting method provided may further include the following step D:

[0173] Step D: If the first UE uses the target transmission resource, or regardless of whether the first UE uses the target transmission resource, start or restart the wait-for-retransmission timer.

[0174] For example, when the first UE starts or restarts the wait-for-retransmission timer, it can also refrain from monitoring the PDCCH or side link authorization during the waiting-for-retransmission timer's timeout period.

[0175] The aforementioned target transmission resource is at least one transmission resource authorized by the side link.

[0176] For example, taking at least one transmission resource of the configured sidelink grant as an example, if the first UE actually uses at least one transmission resource of the configured sidelink grant for transmission, the first UE starts or restarts the RTT Timer and does not monitor the PDCCH or SL DCI during the RTT Timer period; or, regardless of whether the first UE actually uses at least one transmission resource of the configured sidelink grant for transmission, the first UE starts or restarts the RTT Timer and does not monitor the PDCCH or SL DCI during the RTT Timer period.

[0177] Optionally, in this embodiment of the invention, the first UE may also report relevant information about the target discontinuous transmission mode to the network-side device. For example, the user may report relevant information about bs-scheduled Uu DRX or SL DRX, such as reporting relevant Timer values ​​that the user prefers, can accept, is interested in, or supports.

[0178] The discontinuous transmission configuration method provided in this embodiment of the invention uses target configuration information obtained by the first UE to configure a target discontinuous transmission mode. The target discontinuous transmission mode includes at least one of a first discontinuous transmission mode (i.e., a Uu discontinuous transmission mode using a side link resource allocation mode) and a side link discontinuous transmission mode. Thus, the first UE can configure a target discontinuous transmission mode for itself based on the target configuration information, thereby transmitting in the target discontinuous transmission mode. This can simultaneously meet the requirements of side link services and Uu services, thereby improving the energy efficiency of the communication system.
