[0030] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] It is worth noting that the techniques described in the embodiments of the present application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" are often used interchangeably in the embodiments of the present application, and the described techniques can be used in the above-mentioned systems and radio technologies, as well as in other systems and radio technologies. The following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the following description, but these techniques can also be applied outside the NR system application, such as 6th Generation (6G) communication systems. th

[0033] ​In the embodiment of the present application, the terminal may also be referred to as a terminal device or user equipment (UE). The terminal may be a mobile phone, a tablet personal computer, a laptop computer or a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (Pedestrian UE, PUE) and other terminal-side devices. Wearable devices include: bracelets, headphones, glasses, etc.

[0034] To better understand the solution provided by this application, the following contents are first described:

[0035] Introduction to Vehicle to Everything (V2X)

[0036] LTE systems support sidelink transmission, which allows direct data transmission between end-user devices without going through network equipment. For example, data can be transmitted directly between UEs at the physical layer. LTE sidelink is broadcast-based. While it can support basic safety-related V2X communications, it is not suitable for more advanced V2X services. 5G NR systems will support more advanced sidelink transmission designs, such as unicast, multicast, and groupcast, enabling support for a wider range of services.

[0037] LTE sidelink is designed for specific public safety applications (such as emergency communications in disaster areas like fires and earthquakes) and V2X communications. Vehicle-to-everything (V2X) communications encompass a wide range of services, including basic safety-related communications, advanced (autonomous) driving, platooning, and sensor expansion. Since LTE sidelink only supports broadcast communications, it is primarily used for basic safety-related communications. Advanced V2X services with stringent Quality of Service (QoS) requirements in terms of latency and reliability will be supported via NR sidelink.

[0038] sidelink resource allocation

[0039] NR V2X defines two resource allocation modes: mode 1: base station schedules resources; mode 2: UE decides by itself what resources to use for transmission. At this time, the resource information may come from the base station's broadcast message or pre-configured information. If the UE works in the range of the base station and has a radio resource control (RRC) connection with the base station, it can be mode 1 and / or mode 2. If the UE works in the range of the base station but does not have an RRC connection with the base station, it can only work in mode 2. If the UE is out of the range of the base station, it can only work in mode 2 and make V2X transmission according to pre-configured information.

[0040] For mode 2, the specific working mode is as follows:

[0041] 1) After the resource selection is triggered, the transmitting UE (TX UE) first determines the resource selection window, the lower boundary of the resource selection window is T1 time after the resource selection trigger, and the upper boundary of the resource selection is T2 time after the trigger, wherein T2 is a value selected by the UE implementation within the packet delay budget (PDB) of its TB transmission, and T2 is not earlier than T1. 2) Before resource selection, the UE needs to determine the candidate resource set, according to the measured reference signal receiving power (RSRP) of the resources in the resource selection window and the corresponding RSRP threshold, if the RSRP is lower than the RSRP threshold, the resource can be included in the candidate resource set. 3) After the resource set is determined, the UE randomly selects the transmission resource in the candidate resource set. In addition, the UE can reserve transmission resources for the next transmission in this transmission.

[0042] And NR V2X supports a chain resource reservation method, that is, one SCI can reserve the current resource, and at most two additional resources can be reserved, and in the next resource, two reserved resources can be indicated. In the selection window, dynamic reservation can be used to continuously reserve resources.

[0043] Referring to Figure 1 , four sidelink communication scenarios are shown in the figure.

[0044] Since the terminal or the control node does not necessarily fully understand the transmission state of other terminals / the amount of data to be transmitted / the amount of data per transmission / the buffer state or the transmission mechanism (for example, Modulation and Coding Scheme (MCS), code rate), it can indicate too many resources or inappropriate resources to other terminals, or in some cases, other terminals no longer need the terminal assistance or scheduling resources, for example, all transmissions are successful, no data needs to be transmitted, no more resources are needed or want to adopt other scheduling modes, for example, want to change to mode 2 or mode 1. At this time, the behavior of the terminal needs to be defined, otherwise it will lead to different understanding of the use of resources between UE A / B control nodes, or unnecessary transmission of assistance information and scheduling information.

[0045] The SL resource processing method provided by the embodiments of the present application will be described in detail in combination with the accompanying drawings and some embodiments and application scenarios.

[0046] Referring to Figure 2 The embodiments of the present application provide a SL resource scheduling method, which is executed by a first terminal or a control node, the control node can be a base station or other user equipment, and the embodiments of the present application do not make specific limitations on this, and the method comprises:

[0047] Step 201: performing a target behavior according to specific information;

[0048] In the embodiments of the present application, the target behavior comprises at least one of the following: a first behavior related to scheduling resources and / or scheduling transmission, a second behavior related to scheduling recommended resources and / or recommended transmission, the specific information is obtained from a target terminal, or the specific information is determined by the first terminal or the control node, the target terminal is a second terminal, a terminal having the same group ID as the second terminal, a terminal in the same group as the second terminal or other terminal.

[0049] The above control node can be understood as a base station or a Road Side Unit (RSU) or a device with scheduling capability or a user with scheduling capability or a header user or a leader user;

[0050] Specifically, for the case that the specific information is sent by the target terminal, when the second terminal satisfies the first state and / or the obtained SL target resource includes at least one resource that is not available for the second terminal, the specific information (the content about the first state and the sending mode of the specific information are described in the description of the second terminal side method below) is sent to the first terminal or the control node.

[0051] In some embodiments, performing a target behavior according to specific information comprises:

[0052] perform a target behavior according to whether the specific information is received and / or content of the specific information;

[0053] In the embodiments of the present application, the first terminal or the control node determines its operation according to whether the specific information is received and / or content of the specific information received (it should be noted that the specific information can come from the second terminal, or from a UE having the same group ID as the second terminal or being in the same group as the second terminal, or from other UEs);

[0054] For example, the specific information is request information used for requesting recommended or scheduled resources or stop information used for stopping recommended or scheduled resources.

[0055] For example, the first terminal or the control node receives the request information, and then performs recommendation or scheduling.

[0056] For example, the first terminal or the control node does not receive the stop information, and then performs recommendation or scheduling.

[0057] For example, the first terminal or the control node does not receive the request information, and then stops recommendation or scheduling.

[0058] For example, the first terminal or the control node receives the stop information, and then stops recommendation or scheduling.

[0059] Specifically, for the case where the specific information is determined by the first terminal or the control node, that is, the first terminal or the control node can determine the specific information by itself.

[0060] For example, the specific information is at least one of a measurement result, geographic location information, and situation information of recommended or scheduled resources.

[0061] For example, the first terminal or the control node measures RSRP of a signal from the second terminal, and if the RSRP is higher than a threshold, the first terminal or the control node does not perform recommendation or scheduling.

[0062] For example, the first terminal or the control node finds geographic location information that cannot be obtained by itself, or finds that a distance between the first terminal and the second terminal is greater than a threshold, and then the first terminal or the control node does not perform recommendation or scheduling.

[0063] For example, the first terminal or the control node finds that resources that can be recommended or scheduled by the first terminal do not satisfy a specific condition, and then the first terminal or the control node does not perform recommendation or scheduling.

[0131] (3) determine that the indicated, recommended or scheduled resources are invalid, or determine that the indicated, recommended or scheduled resources are no longer used by the target terminal, or determine that the indicated, recommended or scheduled resources are used by other terminals, i.e. consider the indicated or recommended or scheduled resources (to the second terminal or to UEs in the same group as the second terminal or with the same group ID as the second terminal) invalid, or consider the indicated or recommended or scheduled resources (to the second terminal or to UEs in the same group as the second terminal or with the same group ID as the second terminal) no longer used by the second terminal or no longer used by UEs in the same group as the second terminal or with the same group ID as the second terminal, or consider the indicated or recommended or scheduled resources (to the second terminal or to UEs in the same group as the second terminal or with the same group ID as the second terminal) used by other UEs;

[0132] (4) update the assistance information or scheduling information, for example, remove resources in which the second terminal cannot be used for transmission / can not be suitable for transmission, and indicate the remaining resources and or other resources to the second terminal or to UEs in the same group as the second terminal or with the same group ID as the second terminal;

[0133] (5) turn off the current scheduling mode or update the scheduling mode, for example, from the first mode or the second mode to mode 2, for example, from the second mode to the first mode; for example, to mode 1;

[0134] (6) update the nature of the assistance information or scheduling information, for example, from indicating resources to be used / suitable resources to indicating resources that are not available / not suitable for use.

[0135] It should be noted that when the first terminal or the control node does not receive the request in a period in which the request information is required, the first terminal or the control node can consider that the second terminal no longer needs the resource, and thus no longer indicates the resource to the second terminal, so that the situation of providing too much resource does not occur.

[0136] Specifically, in some embodiments, when the specific information is received at least a second preset number of times, the target behavior is performed, including:

[0137] When the specific information is received at least P2 times, the target behavior is performed;

[0138] In the embodiments of the present application, for the first terminal or the control node, after receiving the specific information at least P2 times, the target behavior is performed, where P2 is greater than or equal to 1;

[0139] Optionally, when the specific information is received at least P2 times within a second preset time period, the target behavior is performed;

[0140] Optionally, the sending end of the specific information P2 times is the same UE or different UEs, for example, multiple different UEs from the same group ID (that is, in addition to the second terminal, the UEs in the same group as the second terminal can send the specific information);

[0141] In some embodiments, the specific information is second specific information (for example, information indicating no transmission demand or no strong transmission demand or indicating that the utilization rate of the indicated resource is not high), and the target behavior includes one or more of the following:

[0142] (1) Stopping sending the assistance information or the scheduling information, that is, no longer sending the assistance information or the scheduling information (to the second terminal or to the UEs in the same group as the second terminal or with the same group ID as the second terminal);

[0143] (2) Stopping indicating, recommending or scheduling the resource, that is, no longer indicating or recommending or scheduling the resource (to the second terminal or to the UEs in the same group as the second terminal or with the same group ID as the second terminal);

[0144] (3) determining that the indicated, recommended or scheduled resource is invalid, or determining that the indicated, recommended or scheduled resource is no longer used by the target terminal, or determining that the indicated, recommended or scheduled resource is used by other terminals, i.e., considering that the indicated or recommended or scheduled resource (to the second terminal or to the UE in the same group as the second terminal or with the same group ID as the second terminal) is invalid, or considering that the indicated or recommended or scheduled resource (to the second terminal or to the UE in the same group as the second terminal or with the same group ID as the second terminal) is no longer used by the second terminal or by the UE in the same group as the second terminal or with the same group ID as the second terminal, or considering that the indicated or recommended or scheduled resource (to the second terminal or to the UE in the same group as the second terminal or with the same group ID as the second terminal) is used by other UEs;

[0145] (4) updating the assistance information or the scheduling information, e.g., removing the resource that the second terminal cannot use for transmission or can not (be suitable for) use for transmission, and indicating the remaining resource and / or other resources to the second terminal or to the UE in the same group as the second terminal or with the same group ID as the second terminal;

[0146] (5) turning off the current scheduling mode or updating the scheduling mode, e.g., from the first mode or the second mode to mode 2, or from the second mode to the first mode, or to mode 1;

[0147] Specifically, in some embodiments, when the specific information is received at least the second preset number of times, the target behavior is performed, including:

[0148] When the specific information is not received at least P3 times, the target behavior is performed.

[0149] In the embodiments of the present application, for the first terminal or the control node, after receiving the specific information at least P3 times, the target behavior is performed, where P3 is greater than or equal to 1;

[0150] Optionally, when the specific information is received at least P3 times within a third preset time period, the target behavior is performed.

[0151] Optionally, the sending end of the specific information P3 times is the same UE or different UEs, e.g., from multiple different UEs of the same group ID (i.e., in addition to the second terminal, the UE in the same group can send the specific information).

[0152] In some embodiments, the specific information is the first specific information (e.g., scheduling request information or assistance request information or resource request information or SR), and the target behavior includes one or more of the following:

[0153] (1) Sending auxiliary information or scheduling information, for example, to the second terminal or to a UE that is in the same group as the second terminal or has the same group ID as the second terminal;

[0154] (2) indicating, recommending, or scheduling resources, for example, to the second terminal or to a UE that is in the same group as the second terminal or has the same group ID as the second terminal;

[0155] Specifically, in some embodiments, when the specific information is not received at least a first preset number of times, executing the target behavior includes:

[0156] When the specific information is not received at least P4 times, the target behavior is performed.

[0157] In the embodiment of the present application, for the first terminal or the control node, after failing to receive the specific information at least P4 times, the target behavior is executed, where P4 is greater than or equal to 1;

[0158] Optionally, when no specific information is received for at least P4 times within a fourth preset time period, executing the target behavior;

[0159] Optionally, the sender of the P4-time specific information is the same UE or different UEs, for example, multiple different UEs from the same group ID (that is, except for the second terminal, UEs in the same group may send specific information);

[0160] In some embodiments, the specific information is second specific information (for example, information indicating that there is no transmission demand or no strong transmission demand or indicating that resource utilization is not high), and the target behavior includes one or more of the following:

[0161] (1) Sending auxiliary information or scheduling information, for example, to the second terminal or to a UE that is in the same group as the second terminal or has the same group ID as the second terminal;

[0162] (2) indicating, recommending, or scheduling resources, for example, to the second terminal or to a UE that is in the same group as the second terminal or has the same group ID as the second terminal;

[0163] In some embodiments, the method further includes: obtaining specific information from the target terminal via a third terminal;

[0164] In the embodiment of the present application, there may be other users between the first terminal or the control node and the second terminal, such as a third terminal (eg Figure 1 In the UE C in FIG, the first terminal or the control node indicates the resource to the third terminal, and the third terminal then indicates the resource to the second terminal for use. Therefore, the second terminal first sends specific information to the third terminal, and the third terminal then forwards it to the first terminal or the control node.

[0165] Optionally, fourth specific information is received from the third terminal, the fourth specific information being determined according to the third specific information sent by the target terminal.

[0166] In the embodiments of the present application, after the third terminal receives the specific information from the second terminal, the third terminal can modify the content of the specific information or not modify the content of the specific information, that is, the specific information sent by the second terminal and the specific information sent by the third terminal can be the same or different. For example, the specific information sent by the second terminal indicates an empty buffer, and the specific information sent by the third terminal indicates stopping resource recommendation or scheduling, that is, as long as the purpose of stopping resource recommendation or scheduling is achieved, that is, at this time, from the perspective of the third terminal, the behavior is to send (to the second terminal) the specific information to the first terminal or the control node, for example, to the base station. It should be noted that the third terminal can indicate that the information is for the second terminal when sending the specific information, or can not indicate it, because the first terminal or the control node only cares whether to stop recommendation or scheduling, and does not care who wants to stop recommendation or scheduling.

[0167] In some embodiments, the method further includes: receiving fifth specific information from the third terminal, the fifth specific information being information determined by the third terminal when the target terminal is monitored to be in the first state;

[0168] In the embodiments of the present application, the second terminal does not send the specific information, but the third terminal finds that the second terminal is in the first state (for example, finds that the second terminal does not use the recommended or scheduled resources at all, or only uses a small part of them), and then the third terminal sends (to the second terminal) the specific information to the first terminal or the control node.

[0169] Referring to Figure 3 The embodiments of the present application provide a SL resource scheduling method, executed by a second terminal, and the method includes:

[0170] Step 301: When the first state is met, and / or the SL target resource obtained by the second terminal includes at least part of the unavailable resources, the specific information is sent to the first terminal or the control node;

[0171] The SL target resource is the resource indicated by the first terminal or the control node.

[0172] The SL resource indicated by the first terminal or the control node to the second terminal can be understood as the resource recommended, suggested, scheduled or allocated by the first terminal or the control node to the second terminal.

[0173] In the embodiments of the present application, the second terminal determines whether to send the specific information according to the first state, and / or the SL target resource obtained by the second terminal contains at least one resource that cannot be used for transmission by the second terminal or can not be (suitable) used for transmission, or the proportion of the resource that cannot be used for transmission or is not suitable in the total recommended resource is greater than a certain threshold, and the second terminal sends the specific information.

[0174] The SL target resource can contain: the resource used for transmission by the second terminal or can be (suitably) used for transmission, and / or the resource that cannot be used for transmission by the second terminal or can not be (suitably) used for transmission. The former can be explained as that the second terminal can consider or must receive or transmit on the resource, and the latter can be explained as that the second terminal can not consider or must avoid receiving or transmitting on the resource.

[0175] The content of the specific information can refer to the related description in the method of the first terminal or the control node, which will not be repeated here.

[0176] The resource that cannot be used by the second terminal includes: the resource that cannot be used, too much or too little resource, or the resource that is not used for transmission, or the resource that cannot be used for transmission. It should be noted that the resource that cannot be used by the second terminal includes the case that the resource is not suitable for the second terminal.

[0177] In some embodiments, the second terminal can transmit the specific information on the first target resource;

[0178] In the embodiments of the present application, the first target resource is at least part of the SL target resource, that is, the first target resource can not be all of the SL target resource; it should be noted that the specific information can be received by the first terminal or the control node, or can be received by any SL UE.

[0179] Further, the first target resource is at least part of the SL target resource (for example, the resource used for transmission and / or can be (suitably) used for transmission by the second terminal in the SL target resource), or can also be a resource outside the SL target resource (for example, a resource obtained by the second terminal itself);

[0180] In some embodiments, the second terminal can skip the detection or transmission of the second target resource;

[0181] In the embodiments of the present application, the second target resource is at least part of the SL target resource, that is, the second target resource can not be all of the SL target resource; it should be noted that the second target resource can be a resource that is not suitable for the second terminal, or can be a resource that is suitable for the second terminal.

[0182] Further, the second target resource is at least part of the at least one SL target resource, i.e. no transmission or reception is performed on at least part of the at least one SL target resource (reception or transmission can still be performed on other resources).

[0183] In some embodiments, the sending of the specific information to the first terminal or the control node satisfies any of the following:

[0184] (a) the sending interval of the N1th and N2th specific information is less than or equal to the sending interval of the two pieces of assistance information or scheduling information;

[0185] For example, the period of the specific information is less than the period of the assistance information.

[0186] Optionally, the N1th and N2th specific information can be adjacent specific information.

[0187] (b) the sending interval of the N3th and N4th specific information is less than or equal to the interval of the resource or resource set indicated by the assistance information or scheduling information;

[0188] For example, the period of the specific information is less than the period of the semi-static resource provided by the scheduling information.

[0189] Optionally, the N3th and N4th specific information can be adjacent specific information.

[0190] (c) the sending interval of the N5th and N6th specific information is less than or equal to the period in the transmission mode.

[0191] The transmission mode is a characteristic of the second terminal service, for example, the service period of the second terminal.

[0192] Optionally, the N5th and N6th specific information can be adjacent specific information.

[0193] (d) the second terminal sends or does not send the specific information at a specific location or within a specific time after receiving the assistance information or scheduling information.

[0194] Optionally, the specific location is the location of the last resource that can send the specific information after receiving the assistance information or scheduling information.

[0195] (e) the second terminal sends or does not send the specific information at a specific location or within a specific time after sending the request information.

[0196] Optionally, the specific location is the location of the last resource that can send the specific information after sending the request information.

[0197] (f) the specific information is sent when the amount of data waiting for transmission is less than a preset threshold (for example, the buffer size is less than a certain threshold).

[0198] For example, when the remaining amount of data to be transmitted is 0, the buffer size is 0;

[0199] In some implementations, when the specific information is first specific information, sending the specific information to the first terminal or the control node satisfies any of the following conditions:

[0200] (1) The interval between the N7th and N8th transmissions of specific information is less than or equal to the interval between the two transmissions of auxiliary information or scheduling information;

[0201] For example: the specific information period is smaller than the auxiliary information period;

[0202] Optionally, the N1th and N2th specific information may be two adjacent specific information;

[0203] (2) The interval between the N9th and N10th transmissions of the specific information is less than or equal to the interval between the resources or resource sets indicated by the auxiliary information or scheduling information;

[0204] For example: the specific information period is smaller than the period of the semi-static resource provided by the scheduling information;

[0205] Optionally, the N3th and N4th specific information may be two adjacent specific information;

[0206] (3) The interval between the N11th and N12th transmissions of the specific information is less than or equal to the period in the transmission mode;

[0207] The transmission mode is a characteristic of the service of the second terminal, such as a service cycle of the second terminal;

[0208] Optionally, the N5th and N6th specific information may be two adjacent specific information;

[0209] Through this method, the interval at which the first terminal or control node sends recommended resource information, the interval at which the control node sends scheduling information, or the period of the resources indicated by them will be greater than the interval at which the second terminal requests resources. Therefore, when no request is received in a period of a certain request information, the first terminal or control node may believe that the second terminal no longer needs resources, and thus no longer indicates resources to the second terminal, thereby avoiding the situation of excessive resource provision.

[0210] When the specific information is second specific information (for example, information indicating that there is no transmission demand or no strong transmission demand or that the utilization rate of the indicated resources is not high), the specific information is sent to the first terminal or the control node, and any one of the following is satisfied:

[0211] (4) the second terminal transmits or does not transmit certain information at certain positions or within certain time after receiving the assistance information or scheduling information;

[0212] Optionally, the certain positions are positions of the latest resources that the second terminal can transmit the certain information after receiving the assistance information or scheduling information.

[0213] (5) the second terminal transmits or does not transmit certain information at certain positions or within certain time after transmitting the request information.

[0214] Optionally, the certain positions are positions of the latest resources that the second terminal can transmit the certain information after transmitting the request information.

[0215] By this method, the second terminal can directly request the first terminal or the control node to stop recommending or scheduling resources, or make the previously configured resources invalid or not to be used by the second terminal, by transmitting certain information explicitly or implicitly.

[0216] It can be understood that the above-mentioned combinations of different certain information and the ways of transmitting the certain information are only examples, and other combinations are not excluded.

[0217] In some embodiments, the first state comprises one or more of the following:

[0218] (a) the buffer is empty;

[0219] (b) the amount of the buffer waiting for transmission is lower than a preset threshold, for example, the buffer size is smaller than a certain threshold;

[0220] (c) retransmission is not needed;

[0221] (d) the number of retransmissions or the maximum number of retransmissions is lower than N, wherein N is a positive integer;

[0222] (e) there is no new data, transport block (TB) or medium access control protocol data unit (MAC PDU) to be transmitted;

[0223] (f) there is no measurement report or measurement result to be transmitted;

[0224] wherein the measurement report or measurement result can be at least one of CSI, RSRP, Received Signal Strength Indication (RSSI), Reference Signal Receiving Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), Signal Noise Ratio (SNR), positioning measurement report, SRS Resource Index (SRI), interference strength, interference status, Channel Busy Rate (CBR), Channel Rate (CR), etc.

[0225] 1) For example: no SL CSI needs to be sent

[0226] Specifically, no data or Transport Block (TB) or Media Access Control Protocol Data Unit (MAC PDU) needs to be sent, and no CSI needs to be sent

[0227] Optionally, case 1: no data or TB or MAC PDU needs to be sent, and no CSI needs to be sent; case 2: no data or TB or MAC PDU but with CSI, the operations of the second terminal are different in the two cases;

[0228] For example, the user can not transmit in case 1, and the user needs to transmit a specific message in case 2;

[0229] 2) For example: no SL RSRP report needs to be sent;

[0230] Specifically, no data or TB or MAC PDU needs to be sent, and no RSRP needs to be sent;

[0231] Optionally, case 3: no data or TB or MAC PDU needs to be sent, and no RSRP needs to be sent, case 4: no data or TB or MAC PDU but with RSRP report, the operations of the second terminal are different in the two cases;

[0232] For example: the user can not transmit in case 3, and the user needs to transmit a specific message in case 4;

[0233] (g) There is no Media Access Control Protocol Service Unit (MAC SDU) or the number of MAC SDUs is 0;

[0234] (h) the second terminal has no transmission demand, for example, the second terminal has no transmission demand within a period of time. Optionally, the no transmission demand may be that there is no detection information to be transmitted;

[0235] (i) a quantity greater than or equal to a first quantity (continuous or non-continuous), or a proportion greater than or equal to a first proportion (continuous or non-continuous) of the SL target resources is not used;

[0236] (j) a quantity greater than or equal to (continuous or non-continuous) a second quantity, or a quantity greater than or equal to (continuous or non-continuous) a second proportion, of the first target resources is not used;

[0237] (k) a third number (continuous or non-continuous) or a third proportion (continuous or non-continuous) of the second target resources is not used;

[0238] (1) less than or equal to a fourth number (continuous or non-continuous), or less than or equal to a fourth proportion (continuous or non-continuous), of the SL target resources are used;

[0239] (m) less than or equal to a (continuous or non-continuous) fifth number, or less than or equal to a (continuous or non-continuous) fifth proportion, of the first target resource is used;

[0240] (n) less than or equal to a (continuous or non-continuous) sixth number, or less than or equal to a (continuous or non-continuous) sixth proportion, of the second target resources is used;

[0241] (o) the battery level is higher than a first threshold;

[0242] (p) No Scheduling Request (SR) or Buffer Status Report (BSR) is triggered or generated;

[0243] (q) triggering the sending of RS, generating RS, or triggering physical layer messages (e.g., Hybrid Automatic Repeat Request ACK (HARQ-ACK));

[0244] At this time, the first method is suitable: for example, the resource is indicated for the second terminal to transmit RS, such as CSI-RS, or a positioning reference signal, etc. Even if the buffer is empty or no data is to be transmitted when transmitting these RS, some data is generated and transmitted to ensure that the reference signal can be correctly transmitted (here, the main consideration is that it must be accompanied by data transmission);

[0245] (r) no RS is triggered to be transmitted, no RS is generated, or no physical layer message is triggered.

[0246] At this time, the second method is suitable: for example, the buffer is empty or no data is to be transmitted, and no physical layer message (such as RS or a message in response to the physical layer) needs to be transmitted, and the resource can be skipped;

[0247] It should be noted that the content of each of the above first states can be understood as that the second terminal may not have a transmission requirement or have a strong transmission requirement or the utilization rate of the indicated resource is not high, so the second terminal may not need to continue to use the resource indicated by the first terminal or the control node. At this time, one method is to skip the indicated resource without transmission; another method is to transmit a specific message on the indicated resource.

[0248] In some embodiments, the first state further comprises one or more of the following:

[0249] (a) the SL target resource, the first target resource, and / or the second target resource is a dynamic resource;

[0250] (b) the SL target resource, the first target resource, and / or the second target resource is a static resource;

[0251] (c) the SL target resource, the first target resource, and / or the second target resource is a semi-static resource.

[0252] In some embodiments, the first state further comprises one or more of the following:

[0253] (a) the second terminal is indicated, configured, pre-configured, or pre-defined to allow skipping of the resource;

[0254] (b) the second terminal indicates (to the first terminal or the control node or other users) a capability of supporting skipping of the resource.

[0255] It should be noted that skipping the indicated resource without transmission can be an optional capability or an operation that needs to be allowed by the opposite end before it can be executed, so the second terminal can skip the indicated resource only after it supports the capability or is indicated to allow skipping.

[0256] In some embodiments, the first state further comprises one or more of the following:

[0257] (a) the second terminal expects or is undergoing a change in scheduling mode;

[0258] (b) the second terminal expects or is undergoing a change in transmission mode (cast type);

[0259] For example: no longer unicast transmission, but entering broadcast or groupcast transmission;

[0260] (c) the second terminal expects or is undergoing a change in link quality;

[0261] For example: the connection quality between the second terminal and the first terminal or the control node is worse than a certain threshold, or P times of retransmission occurs, or Q times of Discontinuous Transmission (DTX) occurs;

[0262] It should be noted that: due to the change in the scheduling mode of the second terminal, it may not be necessary to use the indicated resource, but to use the resource obtained in other ways. The first terminal or the control node may indicate the resource to the second terminal because the second terminal and the first terminal or the control node maintain a unicast or RRC link, so when the transmission mode changes or the link quality changes, the second terminal may not need to use the indicated resource, but to use the resource obtained in other ways.

[0263] In some embodiments, the above-mentioned resource unsuitable for the second terminal includes one or more of the following:

[0264] (a) the resource is preempted by other terminals;

[0265] (b) the resource does not match the data, TB or MAC PDU size that the second terminal needs to transmit, i.e. the resource cannot accommodate or cannot hold the MAC PDU or TB that the second terminal wants to transmit (send or receive) (for example, the size is not enough, the priority does not match);

[0266] (c) the resource has an interference level higher than a second threshold, and optionally the interference level can be an RSRP value, etc.

[0267] (d) the resource has a measurement result higher than a third threshold;

[0268] (e) the resource causes the Channel Rate (CR) to exceed a fourth threshold;

[0269] (f) the resource is not within the sensing window;

[0270] (g) resources not in a selection window;

[0271] (h) resources not in a candidate resource set;

[0272] (i) resources that the second terminal cannot monitor;

[0273] (j) resources that overlap in time domain and / or frequency domain with a first resource, wherein a (past / present / future / potential) transmission direction of the second terminal on the first resource is opposite to a (past / present / future / potential) transmission direction on the SL target resource;

[0274] For example, the first terminal or the control node indicates resource 1 to the second terminal for the second terminal to transmit, but this resource overlaps with resource 2 reserved by the third terminal and used to send packets to the second terminal, i.e., the expected transmission direction of the second terminal on resource 1 is transmission, and the expected transmission direction on resource 2 is reception, due to the half-duplex constraint, the second terminal can only discard one of resource 1 and resource 2;

[0275] (k) resources that overlap in time domain and / or frequency domain with a second resource, wherein the second resource is a resource indicated to the second terminal by another terminal or another control node, or a prior collision, e.g., at a certain time point in the past, the second resource has been used for transmission by another terminal, but the second terminal does not know this information, and still selects to transmit on this resource, thus a collision occurs; or a post collision, e.g., the second resource is reserved for use by another terminal at a certain time point in the future, and if the second resource is indicated to the second terminal, a collision will occur at the certain time point in the future;

[0276] (l) resources for which the number of retransmissions exceeds Q when the resources are selected for transmission by the first terminal or the control node, wherein Q is a positive integer;

[0277] (m) resources for which at least O times of transmission occur out of time or do not meet a packet delay budget PDB requirement, wherein O is a positive integer.

[0278] In some embodiments, the first state comprises one or more of the following:

[0279] (1) a measurement result or a channel state is higher than a first preset threshold and / or lower than a second preset threshold, wherein the measurement result or the channel state is obtained by the second terminal, or the measurement result or the channel state is obtained by the first terminal or the control node;

[0280] The measurement result includes at least one of CSI, RSRP, RSSI, RSRQ, SINR, SNR, positioning measurement report, SRI, interference intensity, interference status, CBR, CR, path loss, etc.;

[0281] For example: when the RSRP measurement result is higher than a certain threshold 1, it indicates that the first terminal or control node is very close to the second terminal and does not need the auxiliary information or scheduling information of the first terminal or control node. At this time, the second terminal sends a specific message, and the first terminal or control node stops recommending or scheduling resources, or the indicated, scheduled or recommended resources are invalid (for example, no longer used by the second terminal); conversely (the second terminal may or may not send a specific message), the first terminal or control node may recommend or schedule resources.

[0282] For example, when the path loss is lower than a certain threshold 2, it indicates that the first terminal or control node is very close to the second terminal and does not need auxiliary information from the first terminal or control node. In this case, the second terminal sends a specific message, and the first terminal or control node stops recommending or scheduling resources, or the indicated, scheduled, or recommended resources are invalid (for example, they are no longer available to the second terminal). Conversely, (the second terminal may or may not send a specific message), the first terminal or control node may recommend or schedule resources.

[0283] For example, when the CSI measurement result is too poor or lower than a certain threshold 3 or higher than a threshold 4, the second terminal sends a specific message, and the first terminal or the control node stops recommending or scheduling resources, or the indicated, scheduled, or recommended resources are invalid (for example, no longer available to the second terminal). Conversely, (the second terminal may or may not send the specific message), the first terminal or the control node may recommend or schedule resources.

[0284] (2) geographic location status, including: whether the distance between the first terminal or the control node and the second terminal is greater than a preset value, and / or whether the first terminal or the control node and the second terminal are in the same zone, and / or whether the first terminal or the control node and the second terminal have geographic location information, and / or whether the second terminal has geographic location information, wherein the geographic location status is obtained by the second terminal, or the geographic location status is obtained by the first terminal or the control node;

[0285] For example, if the distance is greater than a threshold, the second terminal sends a specific message, the first terminal or the control node stops recommending or scheduling resources, or the indicated, scheduled, or recommended resources are invalid (for example, no longer available to the second terminal); conversely (the second terminal may or may not send a specific message), the first terminal or the control node may recommend or schedule resources.

[0286] For example: if the first terminal or control node and the second terminal are not in the same zone, then the second terminal sends a specific information, the first terminal or control node stops resource recommendation or scheduling, or, the indicated or scheduled or recommended resources are invalid (e.g. no longer used by the second terminal); otherwise, the first terminal or control node can perform resource recommendation or scheduling

[0287] For example: if the second terminal cannot obtain the geographical position information, then the second terminal sends a specific information, the first terminal or control node stops resource recommendation or scheduling, or, the indicated or scheduled or recommended resources are invalid (e.g. no longer used by the second terminal); otherwise (the second terminal can or can not send a specific information), the first terminal or control node can perform resource recommendation or scheduling

[0288] (3) the status of the recommended or scheduled resources, including whether the recommended or scheduled resources meet a specific condition, wherein the status of the recommended or scheduled resources is obtained by the second terminal, or the status of the recommended or scheduled resources is obtained by the first terminal or control node.

[0289] For example: the specific condition is that at least X% or Y of the recommended or scheduled resources meet a first condition, in fact, the recommended or scheduled resources cannot meet this requirement, then the second terminal sends a specific information, the first terminal or control node stops resource recommendation or scheduling, or, the indicated or scheduled or recommended resources are invalid (e.g. no longer used by the second terminal); otherwise (the second terminal can or can not send a specific information), the first terminal or control node can perform resource recommendation or scheduling.

[0290] In some embodiments, the method further comprises:

[0291] (1) obtaining, by a third terminal, the SL target resources indicated by the first terminal or control node;

[0292] (2) sending, by the third terminal, the specific information to the first terminal or control node.

[0293] In the embodiments of the present application, there can be other users between the first terminal or control node and the second terminal, for example, a third terminal (e.g. UE C in Figure 1 The first terminal or control node indicates resources to the third terminal, and the third terminal indicates the resources to the second terminal for use, so the second terminal sends a specific information to the third terminal first, and the third terminal forwards the specific information to the first terminal or control node.

[0294] Optionally, the sending of the specific information from the third terminal to the first terminal or the control node comprises: sending third specific information to the third terminal, determining fourth specific information by the third terminal according to the third specific information, and sending the fourth specific information from the third terminal to the first terminal or the control node.

[0295] In the embodiments of the present application, after the third terminal receives the specific information from the second terminal, the third terminal can modify the content of the specific information or not modify the content of the specific information, that is, the specific information sent by the second terminal and the third terminal can be the same or different. For example, the specific information sent by the second terminal indicates an empty buffer, and the specific information sent by the third terminal indicates stopping resource recommendation or scheduling. That is, as long as the purpose of stopping resource recommendation or scheduling is achieved, that is, from the perspective of the third terminal, the behavior is to send (the specific information for the second terminal) the specific information to the first terminal or the control node, for example, to the base station. It should be noted that the third terminal can indicate that the information is for the second terminal when sending the specific information, or can not indicate it, because the first terminal or the control node only cares whether to stop recommendation or scheduling, and does not care who wants to stop recommendation or scheduling.

[0296] In some embodiments, the second terminal does not send the specific information, but the third terminal finds that the second terminal is in the first state (for example, finds that the second terminal does not use the recommended or scheduled resources at all, or only uses a small part of them), and then the third terminal sends (the specific information for the second terminal) the specific information to the first terminal or the control node.

[0297] The method of the present application will be described below in combination with specific embodiments, wherein the first terminal is referred to as UE A, and the second terminal is referred to as UE B:

[0298] Embodiment 1: periodically sending the specific information;

[0299] Suppose that the way of sending resource request by the UE B is a periodic request information, for example, it can be SL SR and or SLBSR, then the frequency of sending the specific information by the UE B is higher than the frequency of recommending resources by the UE A (for example, the period of the specific information is less than the period of the recommended resources by the UE A), or, the frequency of sending the specific information by the UE B is higher than the traffic pattern reported by the UE B to the UE A, so that if the UE A does not receive the specific information in a certain period, it is considered that there is no need to recommend resources again;

[0300] Assume UE B sends resource request in a periodic manner, e.g. SL SR and or SL BSR, then UE B sends the specific information more frequently than the control node schedules resources (e.g. the specific information period is less than the control node schedules resources period), or, UE B sends the specific information more frequently than the traffic pattern UE B reports to the control node, so if the control node does not receive the specific information in a certain period, it considers that there is no need to schedule resources again;

[0301] Assume UE B sends resource request in a periodic manner, e.g. SL SR and or SL BSR, then UE B sends the specific information more frequently than the control node schedules resources (e.g. the specific information period is less than the control node schedules resources period), or, UE B sends the specific information more frequently than the traffic pattern UE B reports to the control node, so if the control node does not receive the specific information in a certain period, it considers that there is no need to schedule resources again;

[0302] Embodiment 2: Stop resource recommendation or scheduling;

[0303] 1. Based on large scale channel condition, e.g. when RSRP measurement is higher than a certain threadhold, it means UE A or control node is very close to UE B, no need of UE A or control node assistance information, at this time UE A or control node stops resource recommendation or scheduling, or, the indicated or scheduled or recommended resources are invalid (e.g. no longer used by UE B); e.g. when the path loss is lower than a certain threadhold, it means UE A or control node is very close to UE B, no need of UE A or control node assistance information, at this time UE A or control node stops resource recommendation or scheduling, or, the indicated or scheduled or recommended resources are invalid (e.g. no longer used by UE B); vice versa, optionally, UE A or control node can perform resource recommendation or scheduling;

[0304] 2. Based on geographical location information, e.g. UE A or control node is farther than a certain distance to UE B, and / or, UE A or control node is not in the same zone as UE B, and / or, UE A or control node does not have geographical location information of UE B, and / or, UE B does not have geographical location information, at this time UE A or control node stops resource recommendation or scheduling, or, the indicated or scheduled or recommended resources are invalid (e.g. no longer used by UE B); vice versa, optionally, UE A or control node can perform resource recommendation or scheduling;

[0305] 3. Based on channel condition, e.g. CSI measurement is too bad or lower than a certain threshold 1 or higher than a certain threshold 2, at this time UE A or controlling node stops resource recommendation or scheduling, or, indicated or scheduled or recommended resource is invalid (e.g. no longer to be used by UE B); vice versa, UE A or controlling node can perform resource recommendation or scheduling.

[0306] 4. Based on recommended or scheduled resource, e.g. recommended or scheduled resource does not meet certain condition (e.g. requirement is that at least X% or Y of recommended or scheduled resource meet certain condition, in fact recommended or scheduled resource cannot meet this requirement), at this time UE A or controlling node stops resource recommendation or scheduling, or, indicated or scheduled or recommended resource is invalid (e.g. no longer to be used by UE B); vice versa, UE A or controlling node can perform resource recommendation or scheduling.

[0307] Embodiment 3: MAC CE design

[0308] Certain information can be transmitted in at least one of the following forms:

[0309] a) MAC CE
