[0004] In order to allow various communication systems that use unlicensed spectrum (or unlicensed spectrum, shared spectrum) for wireless communication to coexist in a friendly manner on the spectrum, some countries or regions have stipulated regulatory requirements that must be met when using unlicensed spectrum. For example, communication devices follow the Listen Before Talk (LBT) principle, that is, before a communication device sends a signal on a channel of the unlicensed spectrum, it needs to first perform channel sensing. Only when the channel sensing result is that the channel is idle, the communication device can send a signal; if the channel sensing result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot send a signal.

[0005] In some scenarios, side transmission can also use shared spectrum. In this case, the terminal device needs to perform LBT before performing side transmission. Side transmission is performed only when the channel is detected to be idle. The transmission efficiency is low.

[0052] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0053] Figure 1 1 is a schematic diagram of a communication system applicable to an embodiment of the present application. The transmission resources of the vehicle-mounted terminals (vehicle-mounted terminal 121 and vehicle-mounted terminal 122) are allocated by the base station 110, and the vehicle-mounted terminals send data on the sidelink according to the resources allocated by the base station 110. Specifically, the base station 110 can allocate resources for a single transmission to the terminal, or can allocate resources for a semi-static transmission to the terminal.

[0054] Figure 2 Schematic diagram of another communication system applicable to the embodiment of the present application. The vehicle-mounted terminal (vehicle-mounted terminal 131 and vehicle-mounted terminal 132) autonomously selects transmission resources on the resources of the side link for data transmission. Optionally, the vehicle-mounted terminal can randomly select transmission resources, or select transmission resources by listening.

[0055] It should be noted that device-to-device communication is a sidelink (SL) transmission technology based on device-to-device (D2D). Different from the traditional cellular system where communication data is received or sent by base stations, the Internet of Vehicles system uses direct terminal-to-terminal communication, so it has higher spectrum efficiency and lower transmission latency. 3GPP defines two transmission modes, namely: mode A (sidelink resource allocation mode A) and mode B (sidelink resource allocation mode B).

[0056] Mode A: The transmission resources of the terminal are allocated by the base station, and the terminal sends data on the sidelink according to the resources allocated by the base station; the base station can allocate resources for a single transmission to the terminal, or allocate resources for semi-static transmission to the terminal.

[0057] Mode B: The terminal selects a resource in the resource pool to transmit data.

[0058] Proximity-based Services (ProSe) involve device-to-device communication, mainly for public safety services. In ProSe, by configuring the location of resource pools in the time domain, for example, resource pools are discontinuous in the time domain, the UE can send / receive data discontinuously on the sidelink, thereby achieving power saving.

[0059] The Internet of Vehicles system mainly studies the scenarios of vehicle-to-vehicle communication, and is mainly aimed at the business of relatively high-speed vehicle-to-vehicle and vehicle-to-person communication. In V2X, since the vehicle-mounted system has continuous power supply, power efficiency is not the main issue, but data transmission delay is the main issue, so the system design requires the terminal equipment to send and receive continuously.

[0060] Wearable device (FeD2D) scenario, which studies the scenario of wearable devices accessing the network through mobile phones, mainly focuses on the scenarios of low mobile speed and low power access.

[0061] In FeD2D, a base station can configure the discontinuous reception (DRX) parameters of a remote terminal through a relay terminal.

[0062] In some scenarios, a multi-carrier mechanism is introduced, which is mainly reflected in that the UE can support packet segmentation, transmit data packets through multiple carriers to improve data transmission rate; packet replication, copy an identical data packet twice and send it through two carriers to improve transmission reliability; and multi-carrier reception enhancement at the receiving end. Specifically, for packet replication: sidelink communication supports sidelink packet replication and is executed at the Packet Data Convergence Protocol (PDCP) layer of the UE. For sidelink packet replication for transmission, the PDCP protocol data unit (PDU) is replicated at the PDCP entity. The replicated PDCP PDU of the same PDCP entity is submitted to two different Radio Link Control (RLC) entities and associated with two different sidelink logical channels respectively. The replicated PDCP PDU of the same PDCP entity is only allowed to be transmitted on different sidelink carriers.

[0063] In the New Radio-Vehicle to Everything (NR-V2X), autonomous driving is supported, which puts forward higher requirements for data interaction between vehicles, such as higher throughput, lower latency, higher reliability, larger coverage, more flexible resource allocation, etc.

[0064] In the LTE-V2X system, broadcast transmission is supported, and in the NR-V2X system, unicast and multicast transmission modes are introduced.

[0065] Similar to the LTE V2X system, the NR V2X system can also define the above two resource authorization modes, mode A / mode B. Resource acquisition is indicated by sidelink authorization, that is, the sidelink authorization indicates the time-frequency position of the corresponding physical sidelink control channel (PSCCH) and physical sidelink shared channel (PSSCH) resources.

[0066] In addition to the feedback-free, UE-initiated Hybrid Automatic RepeatreQuest (HARQ) retransmission, feedback-based HARQ retransmission is introduced in NR V2X, which is not limited to unicast communication but also includes multicast communication.

[0067] In NR V2X, since the on-board system has a continuous power supply, power efficiency is not the main issue, but the latency of data transmission is the main issue, so the system design requires the terminal equipment to perform continuous transmission and reception.

[0068] In some scenarios, a communication device (such as a terminal device and a network device) may perform LBT before performing transmission on a cell configured with shared spectrum (or unlicensed spectrum, unlicensed spectrum) channel access. When LBT is applied, the transmitter of the communication device listens to or senses the channel to determine whether the channel is idle or busy, and performs transmission only when the channel is sensed to be idle.

[0069] When the terminal device detects a persistent uplink LBT failure, appropriate measures are taken. The detection is based on each bandwidth part (Band Width Part, BWP) and on all uplink transmissions within the BWP. When a persistent uplink LBT failure is detected on a secondary cell (SCell), the terminal device reports the uplink LBT failure to the corresponding network device through a media access control control element (MAC CE) on a service cell different from the SCell where the failure was detected. If the terminal device has no resources available to transmit the MAC CE, the terminal device can transmit a scheduling request (SR). When a persistent uplink LBT failure is detected on a special cell (SpCell), the terminal device switches to another uplink BWP that is configured with random access channel (RACH) resources on the special cell, initiates RACH, and reports the failure through MAC CE. When multiple uplink BWPs are available for exchange, the terminal device determines which BWP to select to initiate RACH and report the failure. For the primary secondary cell (PSCell), if a persistent uplink LBT failure is detected on all uplink BWPs with configured RACH resources, the terminal device declares a secondary cell group (SCG) radio link failure (Radio Link Failure, RLF) and reports the failure to the master node (Master Node, MN) through SCG failure information (SCGFailureInformation). For the primary cell (PCell), if an uplink LBT failure is detected on all uplink BWPs with configured RACH resources, the terminal device declares RLF.

[0070] In some scenarios, side transmission can also use shared spectrum. In this case, the terminal device needs to perform LBT before performing side transmission, and only performs side transmission when it detects that the channel is idle. The efficiency of side transmission is low. Therefore, how to perform effective side transmission to improve the efficiency of side transmission is an urgent problem to be solved.

[0071] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0072] Figure 3 is a schematic interaction diagram of a wireless communication method 200 according to an embodiment of the present application, such as Figure 3 As shown, the method 200 includes at least part of the following:

[0073] S210, the first terminal receives first indication information, where the first indication information is used to indicate a shared authorized resource;

[0074] S220: Allocate authorized resources to a target logical channel according to the target address information and the priority information of the logical channel, wherein the target logical channel includes at least one logical channel.

[0075] In some embodiments, the method 200 further includes:

[0076] The data to be transmitted on the target logical channel is transmitted using the granted resources.

[0077] In some embodiments, allocating the granted resources to the target logical channel may refer to: allocating the granted resources to data to be transmitted on the target logical channel, or in other words, allocating the granted resources to data transmission on the target logical channel.

[0078] In some embodiments, the data to be transmitted may be sideline data. For example, the first terminal may send the sideline data using a shared authorized resource.

[0079] It should be understood that the embodiments of the present application can be applicable to communication systems on shared spectrum, such as sideline on shared spectrum (SL-U) system, LTE-U system, NR-U system, etc.

[0080] In some embodiments, the target address information (or, can be understood as the target address information corresponding to the first indication information) indicates which target address information the authorized resources can be shared with, or, in other words, the logical channel in which target address information the authorized resources can be shared with, that is, the data transmission on the logical channel in which target address information the authorized resources can be shared with.

[0081] In some embodiments, the target address information may be used to indicate service type information, that is, the target address information may indicate which service type of data transmission the authorized resources indicated by the first indication information can be shared for.

[0082] In the embodiment of the present application, the target address information may be replaced by the target address information corresponding to the first indication information.

[0083] It should be understood that the target address information may be explicitly indicated or implicitly indicated, and this application does not limit this.

[0084] In some embodiments, the target address information is determined based on the target address information carried in the first indication information.

[0085] For example, in a case where the first indication information carries the target address information, the target address information carried in the first indication information is determined as the target address information.

[0086] In other embodiments, if the first indication information does not carry the target address information, the target address information may be any target address information (or not limited to the target address information), or may be specific target address information. Optionally, the specific target address information may be indicated by the network device, or may be predefined.

[0087] In some embodiments, the target address information may be one target address information, or may be a plurality of target address information, or may be any target address information (or in other words, not limited to the target address information).

[0088] In some embodiments, the target logical channel is determined based on target address information.

[0089] In some embodiments, the target address information includes a target address to which the target logical channel belongs.

[0090] That is, the target logical channel is for specific target address information, and the target address for which the target logical channel is targeted is included in the target address information.

[0091] In other words, the authorized resources indicated by the first indication information can be shared for data transmission on the logical channel in the target address information.

[0092] For example, the target address information includes target address A, and the target logical channel is a logical channel in target address A.

[0093] For another example, the target address information includes target address A and target address B, and the target logical channel may be a logical channel in target address A, or may be a logical channel in target address B.

[0094] For another example, the target address information is any target address, and the target logical channel may be a logical channel in any target address.

[0095] In some embodiments, the first indication information is also called channel occupancy time (COT) sharing indication.

[0096] In some embodiments, the first indication information may be used to indicate COT sharing information, and the COT sharing information may be used to determine a shared grant resource.

[0097] In some embodiments, the first indication information is used to indicate at least one of the following:

[0098] The remaining duration of COT, available subband information, channel access priority class (CAPC) information, and COT sharing identification ID information.

[0099] In some embodiments, the COT shared ID information includes at least one of the following:

[0100] Target terminal ID, terminal group ID, service identification information, sideline SL zone (Zone) ID.

[0101] In some embodiments, the target terminal ID may be used to identify terminals that are allowed to share information using the COT.

[0102] In some embodiments, the terminal group ID is used to indicate the terminal group ID that is allowed to use the COT shared information, that is, the terminals in the terminal group identified by the terminal group ID can use the COT shared information.

[0103] In some embodiments, the service identification information is used to indicate the services that are allowed to be transmitted using the COT shared information, that is, the services identified by the service identification information can use the COT shared information.

[0104] In some embodiments, the SL Zone ID is used to identify a zone where COT sharing information can be used.

[0105] In some embodiments, the area where the COT sharing information can be used can be determined by signal quality measurement, such as Reference Signal Receiving Power (RSRP) measurement or Channel Busy Ratio (CBR) measurement.

[0106] In some embodiments, the COT shared information may be shared in an implicit public group, wherein the public group may determine whether the COT shared information is valid or whether to use the COT shared information based on an evaluation result of a receiving terminal of the COT shared information.

[0107] In some embodiments, the evaluation criteria for the receiving terminal of the COT shared information to evaluate whether the COT shared information is valid may refer to at least one of the following criteria:

[0108] A preset COT sharing range or area, wherein the sharing range or area can be determined by SL Zone ID, RSRP measurement, etc.;

[0109] Channel quality measurement of the receiving terminal, such as RSRP measurement or CBR measurement.

[0110] In some embodiments, in order to ensure that the terminal equipment on the SL-U system can continuously use the channel within the acquired COT, the SL-U frame structure can support a 16us guard period (GP). Optionally, it is possible to consider reusing the cyclic prefix (CP) extension to reduce the GP length.

[0111] In some embodiments, the first indication information may be sent by a first device, and the first device may be a network device, or may be other terminal devices, such as a second terminal.

[0112] That is, the network device may share the acquired COT with the terminal device, or different terminal devices may share the COT, for example, terminal devices that establish a PC5 Radio Resource Control (RRC) connection may share the COT.

[0113] Optionally, the first terminal may use the shared authorized resources to send data to the second device, for example, to send uplink data to a network device, or to send sidelink data to a third terminal.

[0114] Optionally, the third terminal may be the same as the second terminal, or may be different.

[0115] It should be understood that the present application does not limit the specific method for sending the first indication information. For example, when the first device is a network device, the first indication information can be sent through any downlink signaling (or, signaling on the Uu interface). When the first device is a terminal device, the first indication information can be sent through any sideline signaling (or, signaling on the PC5 interface).

[0116] As an example but not limitation, the first indication information is sent through at least one of the following signaling:

[0117] SL MAC CE, PC5-RRC message, downlink MAC CE, RRC message.

[0118] For example, when the first indication information is sent by the network device, the first indication information may be sent via a DL MAC CE or an RRC message.

[0119] For another example, when the first indication information is sent by the second terminal, the first indication information may be sent via a SL MAC CE or a PC5-RRC message.

[0120] In some embodiments, the first indication information may be multiplexed with other data or signaling (eg, sidelink data or sidelink signaling, or downlink data or downlink signaling) for transmission, or may be transmitted separately, that is, may not be multiplexed with other data or signaling for transmission.

[0121] In some embodiments, the first indication information may be multiplexed and transmitted with data or signaling that overlaps with the target address information.

[0122] For example, the target address information includes target address information of data or signaling multiplexed and transmitted with the first indication information.

[0123] In some embodiments, the first indication information is resource multiplexed and transmitted with a first MAC service data unit (SDU) or a first SL MAC CE.

[0124] In some implementations, the first MAC SDU or the first SL MAC CE corresponds to the first target address information, and the target address information carried by the first indication information includes the first target address information.

[0125] In some other implementations, the first MAC SDU or the first SL MAC CE is the MAC SDU or MAC CE to be transmitted by the transmitting device of the first indication information. That is, the first MAC SDU or the first SL MAC CE may be the MAC SDU or MAC CE that the transmitting device currently needs to transmit.

[0126] In some cases, the first indication information carries a target address information, and the first target address information is the target address information, that is, the first MAC SDU or the first SL MAC CE may be a MAC SDU or MAC CE corresponding to the first target address information.

[0127] That is to say, the transmitting device may transmit the first indication information and the MAC SDU or SL MAC CE corresponding to the same target address information after resource multiplexing.

[0128] For another example, the first indication information carries multiple target address information, and the first target address information is any target address information among the multiple target address information. That is, the first MAC SDU or the first SL MAC CE can be a MAC SDU or MAC CE corresponding to any target address information among the multiple target address information.

[0129] That is to say, the transmitting device may transmit the first indication information and the MAC SDU or SL MAC CE of any target address information among the multiple target address information corresponding to the first indication information after resource multiplexing.

[0130] For another example, the first indication information does not carry the target address information, and the target address information of the first MAC SDU or the first SL MACCE is any target address information.

[0131] The fact that the first indication information does not carry the target address information may indicate that the shared authorized resources may be shared with the logical channel in any target address. Therefore, the first MAC SDU or the first SL MAC CE may be a MAC SDU or MAC CE corresponding to any target address.

[0132] That is to say, when the authorized resources indicated by the first indication information can be shared with the logical channel in any target address, the sending device can transmit the first indication information and the to-be-transmitted MAC SDU or SL MAC CE corresponding to any target address information after resource multiplexing.

[0133] In some other embodiments, the first indication information may not be resource multiplexed with the MAC SDU or SLMAC CE of any target address information. For example, the first indication information may be transmitted separately.

[0134] In some embodiments of the present application, before allocating resources to a logical channel, the first terminal first selects a logical channel, that is, selects a target logical channel to which authorized resources are allocated, that is, selects which logical channels to which shared authorized resources are allocated.

[0135] In some embodiments, the method 200 further includes:

[0136] A target logical channel is selected from the logical channels included in the target address information.

[0137] For example, the first terminal may select a target logical channel from among the logical channels in the target address information according to whether there is data to be transmitted on the logical channel, at least one of the HARQ attribute of the logical channel and the resource attribute available for the logical channel.

[0138] As an embodiment, the first terminal first determines a candidate logical channel set according to the target address information, wherein the logical channels in the candidate logical channel set belong to the target address information;

[0139] Further, the target logical channel is selected from the candidate logical channel set according to whether there is data to be transmitted on the logical channel, at least one of the HARQ attribute of the logical channel and the resource attribute available for the logical channel.

[0140] In some embodiments, the HARQ attribute of the logical channel may include whether HARQ feedback of the logical channel is enabled.

[0141] In some embodiments, the resource attributes that can be used by the logical channel may include at least one of the following:

[0142] Whether the logical channel is allowed to use the configured grant (CG) resources, or whether the data to be transmitted on the logical channel is allowed to be transmitted using the CG resources;

[0143] List of CG resources available for logical channels.

[0144] In some embodiments, the logical channel may be configured with at least one of the following parameters:

[0145] Sidelink CG allowed (sl-configuredgranttypeallowed), used to configure whether to allow the logical channel to use CG resources for sidelink transmission;

[0146] The sideline allowed CG list (sl-allowedCG-list) is used to configure the CG resources for sideline transmission that are allowed to be used by the logical channel;

[0147] Sidelink HARQ feedback enable (sl-HARQ-FeedbackEnabled) is used to configure whether to enable HARQ feedback of the logical channel.

[0148] In some embodiments, the target logical channel is a logical channel that satisfies at least one of the following conditions:

[0149] Condition 1: There is data to be transmitted on the target logical channel;

[0150] Condition 2: when the authorized resource indicated by the first indication information is a CG resource, the target logical channel is configured to allow the use of the CG resource;

[0151] Condition 3: When the authorized resource indicated by the first indication information is a CG resource, the available CG resource configuration corresponding to the target logical channel includes the CG resource indicated by the first indication information;

[0152] Condition 4: The HARQ attribute of the target logical channel is the same as the HARQ attribute corresponding to the logical channel with the highest priority.

[0153] In some embodiments, the target address information includes one target address information, and the target logical channel belongs to the one target address information.

[0154] In some embodiments, the target address information includes multiple target address information, and the target logical channel belongs to the second target address information in the multiple target address information. For example, the second target address information is the target address information of the logical channel with the highest priority in the multiple target address information. Optionally, the logical channel with the highest priority may refer to the logical channel with the highest priority in the logical channels that meet at least one of the above conditions 1 to 3.

[0155] In some embodiments, the HARQ attribute of the target logical channel is the same as the HARQ attribute corresponding to the logical channel with the highest priority, which may include:

[0156] The target logical channel and the highest priority logical channel both enable HARQ feedback; or

[0157] Neither the target logical channel nor the highest priority logical channel has HARQ feedback enabled.

[0158] In some embodiments, the target logical channel is configured to allow the use of CG resources, including:

[0159] The sideline CG type corresponding to the target logical channel allows the sl-configuredgranttypeallowed parameter to be set to true.

[0160] In some embodiments, the available CG resource configuration corresponding to the target logical channel includes the CG resource indicated by the first indication information, including:

[0161] The sideline allowed CG list sl-allowedCG-list configuration corresponding to the target logical channel includes the CG index (configured grant index) corresponding to the authorized resource indicated by the first indication information, that is, the target logical channel is allowed to use the authorized resource indicated by the first indication information.

[0162] In some embodiments of the present application, the S220 includes:

[0163] The authorized resources indicated by the first indication information are allocated to the target logical channel in descending order of the priority of the logical channel. That is, resources are allocated to the selected logical channel (ie, the target logical channel) in descending order of the priority of the logical channel.

[0164] In some embodiments, the network device may configure the following parameters for each logical channel through RRC signaling:

[0165] Logical channel priority (priority). The smaller the value of the priority, the higher the corresponding priority.

[0166] Prioritized Bit Rate (PBR), which indicates the minimum rate that the logical channel needs to guarantee;

[0167] Bucket Size Duration (BSD): This parameter determines the depth of the token bucket corresponding to the logical channel.

[0168] In some embodiments, the MAC layer of the first terminal may maintain a variable SBj for each logical channel j, where j is an integer, and SBj is set as follows:

[0169] (1) When establishing logical channel j, initialize SBj to 0;

[0170] (2) Before each logical channel priority (LCP) processing, SBj is increased by PBR*T, where T is the time interval from the last time SBj was increased to the current time;

[0171] (3) If the SBj updated according to step 2 is larger than the side token bucket capacity (ie, PBR*BSD), SBj is set to the side token bucket capacity.

[0172] In some embodiments of the present application, allocating the authorized resources to the target logical channel according to the target address information and the priority information of the logical channel includes:

[0173] Step 1: Select logical channel j whose SBj is greater than 0 in the target logical channel, and allocate resources to each logical channel in descending order of priority of the logical channel;

[0174] In some embodiments, if the PBR of logical channel j is set to be infinite, resources are allocated to all data to be transmitted on logical channel j, and then resources are allocated to logical channels with a lower priority than logical channel j.

[0175] Step 2: Subtract the size of the MAC SDU allocated to logical channel j from the SBj corresponding to logical channel j to obtain an updated SBj.

[0176] Optionally, if there are remaining authorized resources after executing step 1 and step 2, regardless of the size of SBj, the remaining authorized resources are allocated to each logical channel in order of logical channel priority from high to low. Only when the data of the high-priority logical channel has been sent and the authorized resources have not been exhausted, the low-priority logical channel can be served. Logical channels with the same priority should be served equally.

[0177] In some embodiments of the present application, the method 200 further includes:

[0178] The first terminal sends second indication information, where the second indication information is used to indicate whether to use shared authorized resources.

[0179] In some embodiments, the first terminal may determine whether to use the shared authorized resources.

[0180] Optionally, in the absence of a logical channel that satisfies at least one of the aforementioned conditions 1 to 4, the first terminal determines not to use the shared authorized resources. For example, if the candidate logical channel set does not include a logical channel with data to be transmitted, or the authorized resources indicated by the first indication information are CG resources, but the logical channels in the candidate logical channel set are not allowed to use CG resources, or the list of CG resources allowed for use does not include the CG resources indicated by the first indication information, the first terminal may determine not to use the shared authorized resources.

[0181] In some embodiments, the first terminal may send the second indication information to the first device, and the first device may be a network device or another terminal, such as the second terminal.

[0182] In some embodiments, the second indication information is sent in at least one of the following ways:

[0183] Feedback through the feedback resource corresponding to the first indication information;

[0184] Feedback through MAC CE;

[0185] Feedback via PC5-RRC message;

[0186] Feedback via RRC message.

[0187] In some embodiments, the feedback resource feedback corresponding to the first indication information includes:

[0188] Feedback is provided through a physical sidelink feedback channel (PSFCH) or a physical uplink control channel (PUCCH).

[0189] In some embodiments, the first indication information may be fed back through a MAC CE, which may include that the first indication information may be fed back through a newly added MAC CE or an existing MAC CE.

[0190] For example, the second indication information is fed back through the first MAC CE, and the first MAC CE is dedicated to feeding back whether the shared authorized resources are used, that is, the first MAC CE may be a MAC CE dedicated to COT shared feedback.

[0191] In some embodiments, the second indication information is used to indicate at least one of the following states:

[0192] correctly receiving the first indication information but not using the authorized resources indicated by the first indication information;

[0193] correctly receiving the first indication information and using the authorized resources indicated by the first indication information;

[0194] The first indication information is not received correctly.

[0195] In some embodiments of the present application, the method 200 further includes:

[0196] When it is determined to use the authorized resources indicated by the first indication information, the MAC layer is triggered to perform resource reselection.

[0197] For example, when the first terminal determines to use the shared authorized resources, the first terminal can use the authorized resources to transmit the data currently to be transmitted, that is, not use the previously selected resources, and further trigger MAC layer resource reselection for subsequent data transmission.

[0198] Optionally, for the first terminal adopting the transmission mode of mode B (i.e., the first terminal autonomously selects resources for side transmission in the resource pool), when it is determined to use the authorized resources indicated by the first indication information, the MAC layer is triggered to reselect resources.

[0199] Optionally, in some embodiments, the method 200 further includes:

[0200] After using the authorized resources indicated by the first indication information, the MAC layer is triggered to perform resource reselection.

[0201] For example, after the first terminal uses the shared authorized resources, the first terminal may trigger MAC layer resource reselection again for subsequent data transmission.

[0202] In some embodiments of the present application, the design of the shared COT needs to consider information such as the processing time of the COT sharing indication and the minimum listening time required by regulations.

[0203] In some embodiments, the inheritance and forwarding of COT shared information needs to meet the following processing time conditions:

[0204] The time length between the end position of the symbol receiving the COT sharing indication and the start position of the symbol sending the COT sharing indication is greater than or equal to Tproc,SL-U, where Tproc,SL-U is the processing time that needs to be considered for inheritance and forwarding of COT sharing information.

[0205] In some embodiments, when the first terminal receives multiple COT shared information that meets the processing time condition, the first terminal may select target COT shared information to inherit and forward.

[0206] For example, the first terminal may select the target COT sharing information according to the remaining COT length in the multiple COT sharing information. For example, the COT sharing information with the longest remaining COT length is selected. The COT sharing information with the longest remaining COT length forwarded by the first terminal is determined relative to the sending time of the first terminal.

[0207] For another example, when the remaining COT lengths of multiple COT sharing information are the same, the first terminal selects the target COT sharing information according to the CAPC values ​​in the multiple COT sharing information, for example, selects the COT sharing information with the largest CAPC value.

[0208] In summary, in an embodiment of the present application, the first terminal can receive first indication information sent by other devices (such as a network device or a second terminal), and the first indication information is used to indicate the authorized resources shared by other devices to the first terminal. Furthermore, the first terminal can allocate the shared authorized resources to the target logical channel in the target address information based on the target address information and the priority of the logical channel. Furthermore, the first terminal can perform side transmission based on the shared authorized resources, which is beneficial to improving the side transmission performance.

[0209] In some implementations, the first indication information may be sent via any downlink message or sidelink message. For example, the first indication information may be multiplexed with other data or signaling (e.g., sidelink data or sidelink signaling, or downlink data or downlink signaling) for transmission, or may be transmitted separately, i.e., may not be multiplexed with other data or signaling for transmission.

[0210] In some implementations, the first terminal can determine how to use the authorized resources indicated by the first indication information. For example, the first terminal can first select the target logical channel based on the target address information, and further allocate the shared authorized resources to the target logical channel in order of logical priority from high to low.

[0211] In some implementations, the first terminal may further send second indication information to the sending terminal of the first indication information, to indicate whether the first terminal uses the shared authorized resources.
