Description

[Technical field]

[0001] The present application relates to the field of wireless communication technology, and in particular to an information transmission method, an electronic device, and a storage medium. [Background technology]

[0002] In a sidelink (SL) communication or direct communication system, when a device needs to transmit traffic, the traffic data between the devices is not transmitted through other network devices, but is transmitted from a data source device to a target device, that is, the devices communicate directly with each other. Hereinafter, all direct communications are referred to as SL communication. SL communication can be roughly divided into two communication modes. In the first type of mode, the resource of the sidelink signal transmitted from the terminal (User Equipment, UE) is scheduled by the base station. In the second type of mode, the UE independently selects resources in a resource pool based on a resource selection policy in a network-configured or pre-configured resource pool. Common resource selection policies include sensing mechanism, partial sensing mechanism, random selection mechanism, etc., and for the second type of mode, the independent selection of the UE brings more resource collisions, and the associated cooperation between the UEs can reduce resource collisions and improve resource utilization. Therefore, in the SL communication, attention should be paid to the resource cooperation function between the UEs. In SL communication, in order to support resource selection or reselection of the second terminal (UE-B), the first terminal (UE-A) Coordination information 1 is a group of resources that are desirable to be used for UE-B transmission, or a group of resources that are undesirable to be used for UE-B transmission; The resource to be used in the future indicated by UE-B will cause a resource conflict, and two types of cooperation information can be sent: cooperation information 1, which is called resource conflict indication for short;

[0003] Currently, the cooperation information 2 or the resource collision indication is carried and transmitted on a physical sidelink feedback channel (PSFCH). However, it has been determined that there are problems in that the UE-B transmitting the resource collision indication does not take into consideration whether the UE-B has the ability to accept the cooperation information and whether the UE-B can actively detect and handle resource collisions. As a result, the probability of resource collisions in SL communication is still high and there may be waste in resource utilization. Summary of the Invention [Problem to be solved by the invention]

[0004] The main objective of the embodiments of the present application is to provide an information transmission method, electronic device, and storage medium that fully consider the information cooperation capabilities of nodes, reduce resource conflicts in communication, and improve resource utilization.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] It should be understood that the particular embodiments described herein are illustrative of the present application only and are not intended to be limiting of the present application.

[0010] In the following description, the use of suffixes to indicate elements, such as "module", "component", or "unit", is merely for ease of description of the present application and has no specific meaning in itself, so "module", "component", or "unit" can be used interchangeably.

[0011] Currently, for the second type of mode in SL communication, the UE's autonomous selection leads to more resource collisions, and the related technology reduces resource collisions through association cooperation between UEs. Currently, there are two problems when determining the second terminal (UE-B) to transmit the resource collision indication:

[0012] Problem 1: When the first terminal (UE-A) cannot receive UE-B as the receiver, UE-A directly transmits cooperation information, but it does not take into account whether UE-B can receive this cooperation information, nor does it take into account whether there are valid resources to transmit the cooperation information.

[0013] Problem 2: When UE-A discovers that resources reserved by UE-B and another UE (third terminal) collide, whether UE-A should send coordination information to UE-B is not currently considered. It is not considered whether UE-B itself can autonomously discover and handle resource collision (for example, UE-B may use preemption technology to discover and avoid collision with other UEs), or if UE-B cannot discover or handle resource collision in some cases. Only in these cases does UE-A need to send coordination information; conversely, UE-A does not need to send coordination information.

[0014] FIG. 1 is a flow chart of an information transmission method according to an embodiment of the present application, which can be applied to the case of sidelink wireless communication, and the method can be performed by an information transmission device in an embodiment of the present application, which can be realized in a software and / or hardware manner and is generally integrated in a terminal. Referring to FIG. 1, the method according to the embodiment of the present application specifically includes the following steps:

[0015] In step 110, based on the received sidelink control information, it is determined that there is at least one of the following resource collisions: a half-duplex resource collision exists in the reserved resources of the second node; and a resource reservation collision exists in the reserved resources of the second node and the third node.

[0016] In an embodiment of the present application, when the terminal is a first node performing sidelink communication, the terminal can determine a resource conflict based on the received sidelink control information, and the resource conflict includes two types:

[0017] First, the terminal, being a half-duplex device, i.e. being capable of performing only one of receive and transmit operations at the same time, detects a Sidelink Control Information (SCI) of the second node and finds that resources are reserved for this SCI and the terminal is the receiver of the resource, but is unable to receive on that resource due to the half-duplex restriction of the terminal, i.e. being able to transmit but not receive only within the reserved time slot of the resource, thus causing a resource collision, which may be referred to as a half-duplex resource collision existing on the reserved resources of the second node, and in some embodiments the SCI may in particular be a type of SCI carried on the Physical Sidelink Control Channel (PSCCH), i.e. SCI format 1-A.

[0018] Second, the terminal receives the SCI transmitted from the second node and the third node, respectively, detects the SCI and finds that the resources reserved by the second node and the resources reserved by the third node overlap, and if such resources overlap, requests that the terminal may be the recipient of the SCI reserved resources of the second node and the SCI reserved resources of the third node, or requests that the terminal be the intended recipient of the resources reserved for the SCI of the second node or the resources reserved for the SCI of the third node, which can be specifically configured by the typeAUEScheme2 of the protocol, and if this parameter is enabled, it only requests that the terminal be the intended recipient of either the resources reserved for the SCI of the second node or the resources reserved for the SCI of the third node, and if this parameter is disabled, it requests that the terminal be the intended recipient of the resources reserved for the SCI of the second node and the resources reserved for the SCI of the third node.

[0019] In step 120, a second node to transmit a resource conflict indication is determined based on a specified condition.

[0020] Specifically, when a resource detected by the terminal is in conflict, the terminal can determine whether the node satisfies a specified condition, and if the node satisfies the specified condition, the terminal determines this node as a second node that needs to transmit a resource conflict indication and transmits the resource conflict indication to this node.

[0021] In one exemplary embodiment, if the resource conflict is a half-duplex resource conflict, i.e. the terminal is an intended recipient of a transmission made on resources reserved to a second node, but reception on the reserved resources is not possible or desirable due to half-duplex limitations, then the specified condition is: The sidelink control information includes at least one of: enabling a receiving capability indication of the resource conflict indication of the second node; a transmission timing of the resource conflict indication being valid; and a receiving time of the sidelink control information being earlier than the transmission timing of the resource conflict indication by at least a first minimum interval threshold.

[0022] In the embodiment of the present application, when the terminal detects the SCI and determines that the resource conflict is a half-duplex resource conflict, the specified condition for the terminal to determine the second node is: When the capability of receiving a resource conflict indication carried in the sidelink control information is enabled, e.g. configured as the higher layer parameter indicationUEBScheme2 being enabled, the sidelink control information transmitted from the node to the terminal includes information indicating that the node has the capability of receiving a resource conflict indication, which may include, e.g. the indicationUEB flag field in the SCI transmitted from the node being set to 1.

[0023] A transmission timing of the resource conflict indication corresponding to the node is valid. In one embodiment, the transmission timing can be determined by a sidelink control information transmission time or a time of reserved resources. In one embodiment, determining a transmission timing of the resource conflict indication corresponding to the node according to the sidelink control information transmission time includes: a transmission timing of the resource conflict indication is in a first slot including a PSFCH resource in a resource pool at least a first minimum spacing threshold after the sidelink control information transmission time, and a time of the reserved resources is spaced at least a second minimum spacing threshold between the transmission timing of the resource conflict indication. In one embodiment, determining a transmission timing of the resource conflict indication corresponding to the node according to the time of the reserved resources includes: a transmission timing of the resource conflict indication is in a first slot including a PSFCH resource in a resource pool at least a second minimum spacing threshold before the time of the reserved resources, and a time of the resource conflict indication is spaced at least a first minimum spacing threshold between the transmission timing of the sidelink control information transmission time and the transmission timing of the resource conflict indication. The transmission timing of the resource conflict indication corresponding to the node being valid means that the transmission timing of the resource conflict indication determined by the sidelink control information transmission time or the time of the reserved resources has not yet passed.

[0024] The reception time of the sidelink control information is earlier than the transmission timing of the resource conflict indication by at least a first minimum interval threshold, where the first minimum interval threshold may be configured by the network, pre-configured or defined by a protocol, e.g. an upper layer parameter sl-MinTimeGapPSFCH provides the value of the first minimum interval threshold. The time gap between the reception time and the transmission timing of the sidelink control information of the node is equal to or greater than the first minimum interval threshold.

[0025] Specifically, if a node satisfies one or more of the above specified conditions, the node can be determined as a second node capable of receiving a resource conflict indication, and the terminal can transmit the resource conflict indication to the second node.

[0026] In another exemplary embodiment, if the resource conflict is the half-duplex resource conflict, the specified condition is: The method further includes transmitting the resource conflict indication earlier than the reserved resource with half-duplex resource conflict by at least a second minimum spacing threshold.

[0027] In the embodiment of the present application, based on the embodiment of the above application, the specified condition satisfied by the second node determined by the terminal may include that the transmission timing of the resource collision indication of the node is before the time corresponding to the reserved resource where the half-duplex resource collision occurs, and the time length between the transmission timing and the time corresponding to the reserved resource exceeds a second minimum interval threshold, where the second minimum interval threshold may be configured by the network, pre-configured, or defined by a protocol, for example, the value of the second minimum interval threshold is provided to be a value of T3 defined by the protocol.

[0028] FIG. 2 is a flow chart of an information transmission method according to an embodiment of the present application, which is an embodiment of the above application. Referring to FIG. 2, the information transmission method according to the embodiment of the present application includes the following steps:

[0029] In step 210, based on the received sidelink control information, it is determined that a resource reservation conflict exists between the reserved resources of the second node and the third node as a resource conflict.

[0030] In an embodiment of the present application, the terminal determines that a resource collision exists between the reserved resources of the second node and the third node, ie the reserved resources of the second node overlap with the reserved resources of the third node.

[0031] In step 220, a second node to transmit a resource conflict indication is determined based on a specified condition, and the second node satisfies the specified condition.

[0032] Specifically, in the case of a resource conflict, if a second node is detected to satisfy a specified condition, the terminal may select this second node as the second node that transmits a resource conflict indication.

[0033] In one exemplary embodiment, the specified condition satisfied by the second node is: The transmission timing of the resource collision indication is valid; and detecting that the reception time of the sidelink control information of the second node is earlier than the transmission time of the resource collision indication by at least a third minimum time interval; the sidelink control information enabling an indication of a capability of receiving the resource conflict indication of the second node; the third node does not satisfy the second specified condition.

[0034] In an embodiment of the present application, the second node may be determined as the second node that transmits the resource conflict indication if one or more of the following are satisfied: the transmission timing of the resource conflict indication is valid; the reception time of the sidelink control information is earlier than the transmission timing of the resource conflict indication and the time interval between the reception time and the transmission timing exceeds a third minimum time interval; the reception capability indication of the resource conflict indication of the second node is enabled in the sidelink control information; and the third node does not satisfy the second specified condition.

[0035] In one exemplary embodiment, the second specified condition is: at least one of: a transmission timing of the resource conflict indication corresponding to the reserved resource of a third node is valid; a reception time of the sidelink control information of the third node is detected to be earlier than the transmission timing of the resource conflict indication by at least a fourth minimum time interval; and the sidelink control information of the third node enables a reception capability indication of the resource conflict indication.

[0036] In an embodiment of the present application, when determining the second node as the second node that transmits the resource conflict indication, the third node does not satisfy at least one of the second specified conditions, the second specified conditions including: a transmission timing of the resource conflict indication indicating a resource conflict of the reserved resources is valid; a reception time of the sidelink control information of the third node is earlier than the transmission timing of the resource conflict and the time interval between the reception time and the transmission timing exceeds a fourth minimum time interval; and a reception capability indication corresponding to the resource conflict indication in the sidelink control information of the third node is enabled.

[0037] In some embodiments, the specified condition satisfied by the second node is: the priority value included in the sidelink control information of the second node is equal to or greater than the priority value included in the sidelink control information of the third node; and the priority value included in the sidelink control information of the second node is lower than the priority value included in the sidelink control information of the third node, and the resource pool to which the reserved resources belong is not configured in preemption mode or a preemption mode parameter is not provided, for example, the upper layer parameter sl-PreemptionEnable is not provided; the priority value comprised in the sidelink control information of the second node is lower than the priority value comprised in the sidelink control information of the third node, and the priority value comprised in the sidelink control information of the second node is lower than a priority threshold corresponding to a configured preemption mode of the resource pool to which the reserved resources belong, e.g. when a higher layer parameter sl-PreemptionEnable is provided and its value is not equal to enabled.

[0038] In an embodiment of the present application, if the resource conflict is a resource reservation conflict, the reserved resources of the second node and the reserved resources of the third node overlap, and the specified conditions for the terminal to determine the second node to which the resource conflict indication is transmitted may include: a priority value in the sidelink control information of the second node is equal to or greater than a priority value in the sidelink control information of the third node; a priority value in the sidelink control information of the second node is less than a priority value in the sidelink control information of the third node, and the resource pool to which the overlapping reserved resources belong is not in preemption mode, and whether it is in preemption mode can be determined specifically according to whether a preemption mode of the resource pool is configured or whether a parameter of the preemption mode is provided; a priority value in the sidelink control information of the second node is less than a priority value in the sidelink control information of the third node, and the resource pool to which the conflicting reserved resources belong is configured in preemption mode, a priority threshold is set for the configuration parameter of the preemption mode, and the priority value of the second node is less than the priority threshold.

[0039] In some embodiments, the specified condition satisfied by the second node is: The priority value included in the sidelink control information of the second node may be less than the priority value included in the sidelink control information of the third node, and the priority value included in the sidelink control information of the third node may be less than a priority threshold corresponding to a configured preemption mode of a resource pool to which the reserved resources belong.

[0040] Specifically, when determining the second node as the second node that transmits the resource collision indication, it can be determined that the second node satisfies the following: a priority value included in the sidelink control information of the second node is lower than a priority value included in the sidelink control information of the third node, and the resource pool to which the conflicting reserved resources belong is configured in a preemption mode, a configuration parameter corresponding to this preemption mode includes a priority threshold, and the priority value of the second node is lower than this priority threshold.

[0041] In one embodiment, a higher priority value indicates a lower priority. FIG. 3 is a flow chart of another information transmission method according to an embodiment of the present application, which is an embodiment of the above application. Referring to FIG. 3, the method according to the embodiment of the present application includes the following steps:

[0042] In step 310, based on the received sidelink control information, it is determined that a resource reservation conflict exists between the reserved resources of the second node and the third node as a resource conflict.

[0043] In step 320, if a specified condition is met, the transmission of the resource conflict indication is abandoned.

[0044] Specifically, the terminal may detect whether a node satisfies a specified condition for abandoning transmission of a resource conflict indication, and if the node satisfies the specified condition, may not transmit a resource conflict indication to this node.

[0045] In one exemplary embodiment, the specified condition is: the priority value included in the sidelink control information of the second node is less than the priority value included in the sidelink control information of the third node and a resource pool to which the reserved resource with the resource conflict belongs is configured in a preemption mode; the priority value included in the sidelink control information of the second node is less than the priority value included in the sidelink control information of the third node and the priority value included in the sidelink control information of the second node is less than a configured priority threshold of a preemption mode of a resource pool to which the reserved resource with the resource conflict belongs.

[0046] In an embodiment of the present application, when a resource conflict exists between the second node and the third node, the second node decides to abandon transmitting the resource conflict indication to the second node if at least one of the specified conditions is satisfied, and the specified conditions may specifically include: when a resource conflict exists between the reserved resources of the second node and the third node and a resource pool to which the reserved resources belong is configured in a preemption mode, or a preemption parameter of the resource pool is provided and set to an enabled state, a priority value in the sidelink control information of the second node is less than a priority value in the sidelink control information of the third node; and when a resource conflict exists between the reserved resources of the second node and the third node and a resource pool to which the reserved resources belong is configured in a preemption mode, a priority value of the second node is less than a priority threshold in the configured preemption mode of the resource pool, or a priority value of the second node is less than a priority threshold in the preemption mode of the resource pool.

[0047] In another exemplary embodiment, the specified condition is: The priority value included in the sidelink control information of the second node exceeds the priority value included in the sidelink control information of the third node and a resource pool to which the reserved resource belongs is configured in a preemption mode; the priority value included in the sidelink control information of the second node exceeds the priority value included in the sidelink control information of the third node and the priority value included in the sidelink control information of the third node is less than a priority threshold corresponding to the configured preemption mode of the resource pool to which the reserved resource with resource conflict belongs.

[0048] Specifically, when a resource conflict exists between the second node and the third node, the second node decides to abandon transmitting the resource conflict indication to the second node if at least one of the specified conditions is satisfied, and the specified conditions may specifically include: when a resource conflict exists between the reserved resources of the second node and the third node and a resource pool to which the reserved resources belong is configured in a preemption mode, or a preemption parameter of the resource pool is provided and set to an enabled state, a priority value in the sidelink control information of the second node exceeds a priority value in the sidelink control information of the third node; and when a resource conflict exists between the reserved resources of the second node and the third node and a resource pool to which the reserved resources belong is configured in a preemption mode, a priority value of the second node exceeds a priority threshold in the configured preemption mode of the resource pool, or a priority value of the second node exceeds a priority threshold in the preemption mode of the resource pool.

[0049] In one exemplary embodiment, when a first UE detects an SCI of a second UE, and the SCI includes a reserved resource of the second UE, but finds that a collision exists for the resource due to a half-duplex restriction, the first UE determines the second UE and transmits a PSFCH to the second UE so that a resource collision indication is provided, the condition is: 1. The first UE is an intended recipient of transmission on the reserved resources of the second UE; 2. It is not desirable for the first UE to transmit on the reserved resources of the second UE, for example, due to half-duplex restrictions, the first UE cannot receive on the reserved resources; 3. A resource collision indication receiving capability indication is enabled, where the SCI sent from the second UE includes information for instructing itself whether it can receive the resource collision indication, i.e., the SCI of the second UE indicates that it can receive the resource collision indication as UE-B; 4. The transmission timing for transmitting the resource collision indication to the second UE is valid, i.e., the transmission timing has not yet passed; 5. The interval between the time when the SCI of the second UE is received and the transmission timing of the resource collision indication is not less than the set minimum interval, i.e., the time when the SCI of the second UE is received is not later than another minimum interval time before the transmission timing.

[0050] In some other embodiments, when the first UE detects the SCI of the second UE and the SCI of the third UE and finds that a collision exists between the reserved resources of the second UE and the reserved resources of the third UE, the conditions under which the first UE determines the second UE and transmits a PSFCH to the second UE such that a resource collision indication is provided include some of the following:

[0051] In scene 1, when both the second UE and the third UE meet all the conditions to be the nodes receiving the resource collision indication, these conditions are: 1. The transmission timings corresponding to the reserved resources of the second UE and the third UE are both valid, i.e., none of the transmission timings has passed; 2. The transmission timing of the resource collision indication and the intervals of the SCIs corresponding to the second UE and the third UE detected by the first UE all satisfy the minimum interval, that is, the reception times of the SCIs of the second UE and the third UE are both earlier than the transmission timing by at least the minimum interval; 3. If the indication of ability to receive a resource conflict indication is enabled, the second UE and the third UE may both indicate that they are able to receive a resource conflict indication.

[0052] Considering scene 1, when the priority value P1 included in the SCI of the second UE exceeds the SCI value P2 of the third UE, the first UE determines the second UE as the node to which the resource pool collision indication is transmitted, and transmits a PSFCH to the second UE so that the resource collision indication is provided.

[0053] In some embodiments, the second UE: 4. If the condition that the transmission timing of the resource collision indication is earlier than the time of the resource collision by at least a second minimum interval is met, the first UE may determine the second UE and transmit a PSFCH to the second UE so that a resource collision indication is provided.

[0054] Scene 2: When only the second UE meets all the above conditions for receiving the resource collision indication, the condition for the first UE to transmit the PSFCH to the second UE so that the resource collision indication is provided is: 1. When a priority value P1 included in the SCI of the second UE is equal to or greater than a SCI value P2 of the third UE, the first UE determines to transmit a PSFCH to the second UE so as to provide a resource collision indication; 2. If the priority value P1 included in the SCI of the second UE is less than the SCI value P2 of the third UE, and pre-emption is not enabled in the resource pool, i.e., pre-emption is not configured in the resource pool, or if the priority value P1 included in the SCI of the second UE is less than the SCI value P2 of the third UE, and a configuration parameter of pre-emption is not provided in the resource pool, the first UE determines to send a PSFCH to the second UE so that a resource collision indication is provided; 3. When the priority value P1 included in the SCI of the second UE is less than the SCI value P2 of the third UE, and the configuration of pre-emption in the resource pool has a priority threshold Ppre, and the value of P1 is equal to or greater than Ppre, the first UE determines to send a PSFCH to the second UE, so that a resource collision indication is provided; 4. If the priority value P1 included in the SCI of the second UE is less than the SCI value P2 of the third UE, and there is a priority threshold Ppre in the pre-emption configuration in the resource pool, and the value of P1 is less than Ppre, the first UE determines to send a PSFCH to the second UE so that a resource collision indication is provided.

[0055] Alternatively, if only the second UE satisfies all the above conditions for receiving the resource collision indication, the condition for the first UE to transmit the PSFCH to the second UE so that the resource collision indication is provided is: The transmission timing of the resource conflict indication corresponding to the second UE may be earlier than the time interval of the reserved resources having the resource conflict.

[0056] In some embodiments, if only the second UE satisfies all the above conditions for receiving a resource conflict indication, the condition for the first UE to transmit a PSFCH to the second UE so that a resource conflict indication is provided is: 1. The transmission timing corresponding to the resource reserved by the second UE is valid and has not expired; 2. The first UE detects that an interval between a receiving time of the SCI of the second UE and a transmitting time of the resource collision indication of the second UE satisfies a minimum interval; 3. if the indication of capability of receiving resource conflict indication is enabled, the second UE indicates that it can receive resource conflict indication; 4. The third UE, (1) The transmission timing of the resource collision indication corresponding to the resource reserved by the third UE is valid and has not passed; (2) the first UE detects that an interval in which the reception timing of the SCI of the third UE is earlier than the transmission timing of the resource collision indication satisfies a minimum interval; (3) if the reception capability indication of the resource conflict indication is enabled, the third UE indicates that it can receive the resource conflict indication; and not satisfying at least one of the above.

[0057] In some other embodiments, 1. The priority value P1 included in the SCI of the second UE is equal to or lower than the SCI value P2 of the third UE, and pre-emption is enabled in the resource pool, i.e., the resource pool is configured to be pre-emption enabled; 2. When the priority value P1 included in the SCI of the second UE is equal to or less than the SCI value P2 of the third UE, and there is a priority threshold Ppre in the pre-emption configuration in the resource pool, and the value of P1 is equal to or less than Ppre, the first UE can decide whether to abandon transmitting the PSFCH to the second UE so that a resource collision indication is provided, or whether to transmit the PSFCH to the second UE so that a resource collision indication is provided.

[0058] In some examples, the condition for the first UE to determine the one UE or the second UE and transmit the PSFCH to the one UE or the second UE such that a resource collision indication is provided may include: When feedback of collision indications by non-intended receivers is disabled for a resource pool, the first UE is an intended receiver of the first resource reserved by the second UE and the second resource reserved by the third UE, or when feedback of collision indications by non-intended receivers is enabled for a resource pool, the first UE is an intended receiver of at least the first resource reserved by the second UE or the second resource reserved by the third UE; a first SCI for the second UE is detected, the first SCI including an indication of a priority value P1 and a first resource for reserved transmission; a SCI for one of the third UEs is detected, the SCI including an indication of a priority value P2 and a second resource for reserved transmission; determining that the first resource and the second resource overlap in time and frequency; It is determined that the PSFCH transmission timing of the resource collision indication corresponding to the second UE is valid and the PSFCH transmission timing of the resource collision indication corresponding to the second UE has not passed; When the capability of indicating a resource collision indication in the SCI is enabled, and the SCI of the second UE is indicated as being able to receive a resource collision indication as the UE-B, for example, the indication value is 1; The second UE's SCI reception time is not later than a configured minimum time interval before the PSFCH timing of the resource collision indication.

[0059] Regarding the third UE: The PSFCH timing of the resource collision indication corresponding to the third UE is invalid, and the PSFCH timing of the resource collision indication corresponding to the third UE is deemed to have passed; The capability of indicating resource collision indication in the SCI is enabled, and the SCI of the third UE is not indicated to be able to receive the resource collision indication as UE-B, for example, the indication value is 0; If at least one condition is met: the SCI reception time of the third UE is later than a configured minimum time interval before the PSFCH transmission timing of the resource collision indication, the first UE determines the second UE and transmits the PSFCH to the second UE so that the resource collision indication is provided.

[0060] When the first UE decides to transmit a PSFCH to the second UE so that a resource collision indication is provided, the second UE: A priority value P1 included in the SCI of the second UE is equal to or greater than a priority value P2 included in the SCI of the third UE; and The priority value P2 included in the SCI of the third UE>the priority value P1 included in the SCI of the second UE, and for the second UE, A preemption mode is not enabled or a preemption enable parameter is not provided in a resource pool to which a reserved resource with a resource reservation conflict corresponding to the second UE belongs; At least one of the following conditions is satisfied: a preemption enabled parameter is provided in a resource pool to which a reserved resource with a resource reservation conflict corresponding to the second UE belongs, and a priority value P1 included in the SCI of the second UE is greater than or equal to a configured priority threshold Ppre of preemption in the resource pool.

The device can be realized by software and / or hardware, and is generally integrated in a terminal, and specifically includes a collision determination module 401 and a node determination module 402.
