[0049] To better understand the technical solutions of the embodiments of this application, the following technical content will be introduced first:
[0050] NR sidelink resource allocation / selection
[0051] There are two resource allocation methods for NR SL: one based on base station scheduling (mode 1) and the other based on UE autonomous resource selection (mode 2). For the base station-scheduled resource allocation method, the sidelink resources used by the UE for data transmission are determined by the base station and notified to the transmitting terminal (TX UE) via downlink signaling. For the UE autonomous resource allocation method, the UE selects available transmission resources from a (pre)configured resource pool. Before resource selection, the UE performs channel sensing, selects a set of resources with less interference based on the sensing results, and then randomly selects resources for transmission from this set.
[0052] For mode 2, the specific operation is as follows: 1) After resource selection is triggered, the TX UE first determines the resource selection window. The lower boundary of the resource selection window is at time T1 after the resource selection is triggered, and the upper boundary is at time T2 after the trigger. T2 is the value selected by the UE within its TB transmission PDB (packet delay budget), and T2 is no earlier than T1. 2) Before resource selection, the UE needs to determine the candidate resource set. The RSRP measured on the resources within the resource selection window is compared with the corresponding RSRP threshold. If the RSRP is higher than the RSRP threshold, the resource is excluded and cannot be included in the candidate resource set. The remaining resources within the resource selection window after resource exclusion form the candidate resource set. The proportion of resources in the candidate resource set to resources in the resource selection window must be no less than x%. If it is less than x%, the RSRP threshold needs to be increased in steps (3dB) before the resource exclusion operation is performed again, until no less than x% of the resources can be selected. 3) After the set of candidate resources is determined, the UE randomly selects transmission resources from the set. In addition, the UE can reserve transmission resources for subsequent transmissions during this transmission.
[0053] NR sidelink resource allocation / selection enhancement
[0054] The enhanced resource allocation schemes are divided into scheme 1 and scheme 2.
[0055] For scheme 1, UE-A determines a resource set and sends a coordination signaling message recommending this resource set to UE-B. UE-B can then consider the resource set recommended by UE-A when making resource selection. The resource set indicated by the coordination signaling message can be either "transmission resources that UE-A prefers to use by UE-B" or "transmission resources that UE-A does not prefer to use by UE-B". The transmission of the coordination signaling message can be triggered by a request signaling message sent by UE-B or by a preset condition.
[0056] For scheme 2, the Physical Sidelink Feedback Channel (PSFCH) serves as coordination signaling, indicating resource conflicts for UE-B. PSFCH transmission is triggered by a preset condition (i.e., resource conflict for UE-B).
[0057] Method for determining non-preferred resources in Inter-UE coordination scheme 1
[0058] For scheme 1, UE-A can recommend a non-preferred resource set to UE-B. UE-A can determine the non-preferred resource in one or more of the following ways:
[0059] Type 1: Non-preferred resource obtained based on condition 1-B-1 option 1: UE-A determines the non-preferred resource based on the resources reserved by other UEs. The RSRP measurement value associated with the reserved resource is greater than a preset threshold in order to protect the reliability of information transmission from UE-B to UE-A.
[0060] Type 2: Non-preferred resource obtained based on condition 1-B-1 option 2: UE-A determines the non-preferred resource based on resources reserved by other UEs, where the RSRP measurement value associated with the reserved resource is less than a preset threshold. The reserved resource can be a reception resource of UE-A, and UE-A sends the non-preferred resource to protect the reception performance of UE-A on the reserved resource.
[0061] Type 3: Non-preferred resource obtained based on condition 1-B-2: UE-A determines the non-preferred resource based on the SL reception resource it does not expect in order to protect the reliability of information transmission from UE-B to UE-A. The non-preferred SL reception resource may include one or more of the following:
[0062] (1) SL transmission resources ( / time resources) of UE-A.
[0063] (2) When UE-B sends PSSCH to UE-A, it causes a conflict in the PSFCH transmission and reception of UE-A, which is a half-duplex conflict.
[0064] (3) When UE-B sends PSSCH to UE-A, it causes a conflict in the PSSCH transmission and reception of UE-A, which is a half-duplex conflict.
[0065] (4) When UE-B sends PSSCH to UE-A, the resources (or time resources) that cause a conflict between UE-A's PSSCH reception and UL transmission.
[0066] (5) When UE-B sends PSSCH to UE-A, it causes a conflict between the PSFCH transmission and UL transmission of UE-A, i.e., a co-transmission conflict.
[0067] (6) When UE-B sends PSSCH to UE-A, it causes multiple PSFCH transmission conflicts of UE-A, i.e., co-transmission conflict.
[0068] Method for determining preferred resources in Inter-UE coordination scheme 1
[0069] For scheme 1, UE-A can recommend a preferred resource set to UE-B. UE-A can determine the preferred resource in at least one of the following ways:
[0070] Type 1: Preferred resource obtained based on condition 1-A-1: UE-A determines the preferred resource based on excluding resources reserved by other UEs. The RSRP measurement value associated with the reserved resource is greater than a preset threshold in order to protect the reliability of information transmission from UE-B to UE-A.
[0071] Type 2: Non-preferred resource obtained based on condition 1-B-2: UE-A determines the non-preferred resource based on excluding the SL reception resources it does not expect, in order to protect the reliability of information transmission from UE-B to UE-A. The non-preferred SL reception resources may include at least one of the following:
[0072] (1) SL transmission resources (or time resources) of UE-A.
[0073] (2) When UE-B sends PSSCH to UE-A, it causes a conflict in the PSFCH transmission and reception of UE-A, which is a half-duplex conflict.
[0074] (3) When UE-B sends PSSCH to UE-A, it causes a conflict in the PSSCH transmission and reception of UE-A, which is a half-duplex conflict.
[0075] (4) When UE-B sends PSSCH to UE-A, the resources (or time resources) that cause a conflict between UE-A's PSSCH reception and UL transmission.
[0076] (5) When UE-B sends PSSCH to UE-A, it causes a conflict between the PSFCH transmission and UL transmission of UE-A, i.e., a co-transmission conflict.
[0077] (6) When UE-B sends PSSCH to UE-A, it causes multiple PSFCH transmission conflicts of UE-A, i.e., co-transmission conflict.
[0078] The transmission type (cast type) of coordination signaling in Inter-UE coordination scheme 1.
[0079] The coordination signaling transmission is based on the request, and the cast type of the coordination signaling transmission is unicast.
[0080] The coordination signaling transmission based on the condition can be one or more of the following: groupcast, broadcast, and unicast.
[0081] As described above, considering that there are multiple possible cast types for coordination signaling transmission, and that different cast types target different UEs, it is necessary to solve how UE-A can transmit different types of coordination information to the corresponding UE-B, so that UE-B can effectively receive and utilize the relevant coordination information.
[0082] The method for determining transmission resources provided in the embodiments of this application will now be described in conjunction with the accompanying drawings:
[0083] See Figure 1 This application provides a method for determining transmission resources. The execution subject of this method is a first terminal, specifically UE-B as described above, and the corresponding peer that performs SL communication with the first terminal is a second terminal, specifically UE-A as described above. The method includes:
[0084] Step 101: The first terminal receives one or more coordination signals sent by the second terminal. The coordination signal carries first information indicating that the second terminal is the first terminal. The information carried by the coordination signal can also be called auxiliary information. It should be noted that, as mentioned above, since the second terminal may send coordination signals in various ways (unicast, multicast, broadcast), the first terminal may receive one or more coordination signals sent by the second terminal.
[0085] Step 102: When the first information indicates the first resource, the first terminal determines the resource type and / or resource selection behavior of the transmission resource according to the transmission type of the coordination signaling; and / or, when the first information indicates the first resource, the first terminal determines the resource type of the first resource according to the first indication information;
[0086] In the case where the first terminal receives multiple coordination signals sent by the second terminal, the multiple coordination signals are transmitted according to a preset timing sequence.
[0087] And / or, when the coordination signaling is a PSFCH signal used for conflict indication, the priority of the coordination signaling is determined according to a preset rule.
[0088] In this embodiment, when the coordination signaling carries first information indicating a first resource, the first terminal determines the resource type and / or resource selection behavior of the transmitted resource based on the transmission type of the coordination signaling or the first indication information. Simultaneously, for the transmission of multiple coordination signals, they are transmitted according to a preset timing sequence, thus ensuring accurate and effective transmission of coordination information. When the coordination signaling is a PSFCH signal used for conflict indication, the priority of the coordination signaling is determined according to preset rules, ensuring minimal mutual interference between the coordination signaling and other signals, and protecting the effectiveness and reliability of the transmission of the coordination signaling or other more important signals.
[0089] In one possible implementation, the transmission resource is a non-preferred resource indicated by the second terminal to the first terminal; that is, there is a correlation between the coordination signaling cast type and the non-preferred resource type.
[0090] The resource types for transmission resources include one or more of the following:
[0091] (1) Type 1, used to represent non-preferred resources obtained based on the first condition;
[0092] (2) Type 2, used to represent non-preferred resources obtained based on the second condition;
[0093] (3) Type 3 is used to represent non-preferred resources obtained based on a third condition.
[0094] It should be noted that the first condition mentioned above can specifically refer to condition 1-B-1 option 1; the second condition mentioned above can specifically refer to condition 1-B-1 option 2; and the third condition mentioned above can specifically refer to condition 1-B-2. The specific methods of condition 1-B-1 option 1, condition 1-B-1 option 2, and condition 1-B-2 can be found in the corresponding descriptions above, and will not be repeated here.
[0095] In one possible implementation, there is a mapping relationship between the transmission type of the above-mentioned coordination signaling and the resource type and / or resource selection behavior.
[0096] In this embodiment, a correspondence is established between the transmission type of coordination signaling (coordination signaling cast type) and the resource type of the transmission resource, creating an association between them. This allows the first terminal to determine the resource type based on the cast type, thus identifying the appropriate scenario for using the resource. Based on this mapping between the transmission type of coordination signaling and the resource type and / or resource selection behavior of the transmission resource, the first terminal determines the resource type and / or resource selection behavior of the transmission resource according to the coordination signaling sent by the second terminal, thereby ensuring accurate and effective transmission of coordination information.
[0097] It should be noted that the coordination signaling sent by the second terminal carries indication information to indicate the transmission type of the coordination signaling. Therefore, when the first terminal receives the coordination signaling sent by the second terminal, it can know the transmission type of the coordination signaling.
[0098] In one possible implementation, the correspondence between the transport type of coordination signaling and the resource type of the transport resource is agreed upon, configured, and / or pre-configured through the protocol; that is, the protocol agrees upon, configures, and / or pre-configures which one or more non-preferred resource types the cast type carries.
[0099] For example, the cast type for coordination signaling can correspond only to non-preferred resources of type 1 and / or type 3;
[0100] For example, the cast type of coordination signaling can correspond to all the non-preferred resources of the above types (Type 1, Type 2, Type 3).
[0101] In one possible implementation, the correspondence between the signaling format of coordination signaling and the resource type of the transmission resource is agreed upon, configured, and / or pre-configured through a protocol. The signaling format includes at least one of Media Control Element (MAC CE), first-stage sidelink control information (1st-stage SCI), and second-stage sidelink control information (2nd-stage SCI). That is, the signaling format carrying different types of non-preferred resources is agreed upon, configured, and / or pre-configured through a protocol to distinguish between different types of non-preferred resources.
[0102] For example: when the resource type of the first resource is Type 1 or Type 2, the coordination signaling is 1st stage SCI; that is, a non-preferred resource of Type 1 or Type 2 is indicated by 1st stage SCI.
[0103] When the resource type of the first resource is Type 3, the coordination signaling is MAC CE or 2nd stage SCI. That is, the non-preferred resource of Type 3 is carried by MAC CE or 2nd stage SCI.
[0104] In one possible implementation, the first terminal determines the resource selection behavior of the transmission resources based on the transmission type of the coordination signaling, including:
[0105] The first terminal determines the resource selection behavior when sending a Transport Block (TB) to the second terminal based on the transmission type of the coordination signaling.
[0106] Specifically, the first terminal determines its resource selection behavior when sending a TB to the second terminal based on the transmission type, including:
[0107] (1) For transmission types of unicast, including one or more of the following:
[0108] (1.1) When the first terminal determines the non-preferred resource indicated by the coordination signaling transmitted in unicast form, the non-preferred resource is used in the process of selecting the transmission resource of the unicast TB. That is, when the first terminal sends the unicast TB to the second terminal, the transmission resource selection of the TB takes into account the corresponding non-preferred resource of the unicast.
[0109] (1.2) If the first terminal can identify the non-preferred resource obtained based on condition option1-B-1 or condition 1-B-2 contained in the coordination signaling, when the first terminal sends a unicast TB to the second terminal, the transmission resource selection of the TB shall take into account the non-preferred resource obtained based on condition option1-B-1 or condition 1-B-2.
[0110] (1.3) If the first terminal can identify that the coordination signaling contains or only contains the non-preferred resource obtained based on condition option 1-B-1 option 2, when the first terminal sends any TB, the transmission resource selection of the TB shall take into account the non-preferred resource obtained based on condition option 1-B-1 option 2.
[0111] (2) For transmission types of groupcast, including one or more of the following:
[0112] (2.1) When the first terminal determines the non-preferred resource indicated by the coordination signaling transmitted in the form of groupcast, the non-preferred resource is used in the process of selecting the transmission resource of the groupcast TB. That is, when the first terminal sends the groupcast TB to the UE group, the transmission resource selection of the TB takes into account the corresponding non-preferred resource of the groupcast.
[0113] (2.2) If the first terminal can identify the non-preferred resource obtained based on condition option 1-B-1 or condition 1-B-2 contained in the coordination signaling, when the first terminal sends a groupcast TB to the UE group, the transmission resource selection of the TB shall take into account the non-preferred resource obtained based on condition option 1-B-1 or condition 1-B-2.
[0114] (2.3) If the first terminal can identify that the coordination signaling contains or only contains the non-preferred resource obtained based on condition option 1-B-1 option 2, when the first terminal sends any TB, the transmission resource selection of the TB will take into account the non-preferred resource obtained based on condition option 1-B-1 option 2.
[0115] (3) For transmission types of broadcast, including one or more of the following:
[0116] (3.1) The first terminal determines, based on the non-preferred resource indicated by the coordination signaling transmitted in the form of broadcast, that when the first terminal sends a broadcast TB, the non-preferred resource is used in the transmission resource selection process of the broadcast TB, that is, when the first terminal sends a broadcast TB, the transmission resource selection of the TB takes into account the corresponding non-preferred resource of the broadcast.
[0117] (3.2) If the first terminal can identify the non-preferred resource obtained based on condition option 1-B-1 or condition 1-B-2 contained in the coordination signaling, when the first terminal sends the broadcast TB, the transmission resource selection of the TB will take into account the non-preferred resource obtained based on condition option 1-B-1 or condition 1-B-2.
[0118] (3.3) If the first terminal can identify that the coordination signaling contains or only contains the non-preferred resource obtained based on condition option 1-B-1 option 2, when the first terminal sends any TB, the transmission resource selection of the TB will take into account the non-preferred resource obtained based on condition option 1-B-1 option 2.
[0119] In one possible implementation, before the first terminal receives the coordination signaling sent by the second terminal, the method further includes: the first terminal sending a request signaling to the second terminal, the request signaling being used to request coordination signaling, which corresponds to the scenario where the first terminal triggers coordination signaling through a request.
[0120] The request signaling or coordination signaling carries first indication information to indicate the resource type of the transmission resource. Specifically, it explicitly indicates the preferred resource type and / or non-preferred resource type contained in the coordination signaling.
[0121] Specifically, when the first resource is a non-preferred resource indicated by the second terminal to the first terminal, the resource type of the first resource includes one or more of the following:
[0122] (1) The first type is used to represent a non-preferred resource obtained based on the first condition (specifically, condition 1-B-1 option 1);
[0123] (2) The second type is used to represent a non-preferred resource obtained based on the second condition (specifically, condition 1-B-1 option 2);
[0124] (3) The third type is used to represent non-preferred resources obtained based on the third condition (specifically, condition 1-B-2);
[0125] When the first resource is a preferred resource indicated by the second terminal to the first terminal, the resource type of the first resource includes one or more of the following:
[0126] (4) The fourth type is used to represent the preferred resource obtained based on the fourth condition (specifically, condition 1-A-1);
[0127] (5) The fifth type is used to represent the preferred resource obtained based on the fifth condition (specifically, condition 1-A-2);
[0128] In one possible implementation, one or more of the following fields are jointly encoded: resource type indication field, preferred resource and non-preferred resource identifier indication field, request signaling and coordination signaling identifier indication field. That is, resource type indication, preferred resource / non-preferred resource indication, and / or request / coordination signaling indication can be jointly encoded to save signaling overhead.
[0129] For example: the indicator field can only indicate the resource type, and the preferred resource / non-preferred resource is implicitly determined based on the resource type;
[0130] For example, one code point in the indicator field indicates whether the signaling is a request signaling, while other code points are used to indicate what type of resource type the signaling carries as a coordination signaling.
[0131] Considering the same UE-B, it may receive multiple coordination signals within a certain time period. Different coordination signals may carry different information. Therefore, it is necessary to solve how the UE-B can effectively distinguish between different coordination signals in order to avoid confusion between different coordination information.
[0132] In one possible implementation, multiple coordination signaling signals are transmitted according to a preset timing sequence, including:
[0133] The first coordination signaling triggered by the request signaling sent by the first terminal among the multiple coordination signalings is sent within a preset latency bound time limit. The second coordination signaling among the multiple coordination signalings other than the first coordination signaling is sent after the preset latency bound time limit.
[0134] In the embodiments of this application, such as Figure 3a As shown, for request-triggered coordination signaling, this signaling is sent within the latency bound after the request is received. Other coordination signals (such as condition-triggered signals) are sent after the latency bound, or after the request-triggered signaling is sent. The purpose is to avoid disrupting the correspondence between requests and their corresponding coordination signals.
[0135] Optionally, the second coordination signaling is one of those transmitted to the first terminal, or has the same destination address as the first coordination signaling, or has the same transmission type as the first coordination signaling.
[0136] Considering that UE-A and UE-B are receiving / transmitting other signals simultaneously while receiving / transmitting coordination signaling, it is necessary to solve how to ensure that the mutual interference between coordination signaling and other signals is minimal, and how to protect the effectiveness and reliability of the transmission of coordination signaling / other more important signals.
[0137] In one possible implementation, such as Figure 3b As shown, the priority of coordination signaling is determined according to preset rules, including:
[0138] When the transmission time of coordination signaling overlaps with that of the Physical Uplink Shared Channel or Physical Uplink Control Channel (PUSCH / PUCCH containing SL HARQ) that includes Hybrid Automatic Repeat Request, if priority determination is performed, the priority of coordination signaling is always lower than or no higher than the priority of PUSCH / PUCCH containing SL HARQ.
[0139] Alternatively, when the transmission time of coordination signaling overlaps with that of PUSCH / PUCCH containing SL HARQ, if priority determination is performed, the priority value of coordination signaling is always greater than or not less than the priority value of PUSCH / PUCCH containing SL HARQ.
[0140] In one possible implementation, the priority of coordination signaling is determined according to preset rules, including:
[0141] When the transmission time of coordination signaling overlaps with that of UCI (e.g., simultaneous transmission or simultaneous one-to-one transmission and one-to-reception), if priority determination is performed, the priority of coordination signaling will always be lower than or no higher than the priority of UCI.
[0142] Alternatively, when the transmission time of coordination signaling overlaps with that of UCI, if priority determination is performed, the priority value of coordination signaling will always be greater than or no less than the priority value of UCI.
[0143] Optionally, the UCI includes at least one of the following:
[0144] (1) UCI transmitted on PUCCH;
[0145] (2) UCI transmitted on PUCCH, and the UCI contains HARQ for DL transmission;
[0146] (3) UCI transmitted on PUSCH;
[0147] (4) UCI transmitted on PUSCH, and the UCI contains HARQ for DL transmission;
[0148] (5) UCI transmitted on a PUCCH with a preset priority index (e.g., the preset priority index is 0 or 1);
[0149] (6) UCI transmitted on a PUCCH with a preset priority index, and the UCI includes HARQ for DL transmission;
[0150] (7) UCI transmitted on PUSCH with a preset priority index;
[0151] (8) A UCI transmitted on a PUSCH with a preset priority index, and the UCI includes a HARQ for DL transmission.
[0152] See Figure 2 This application provides a method for determining transmission resources. The execution subject of this method is a second terminal, specifically UE-A as described above. The corresponding peer that performs SL communication with the second terminal is a first terminal, specifically UE-B as described above. The method includes:
[0153] Step 201: The second terminal sends one or more coordination signals to the first terminal. The coordination signal carries first information indicating that the second terminal is the first terminal. The information carried by the coordination signal can also be called auxiliary information. It should be noted that, as mentioned above, since the second terminal may send coordination signals in various ways (unicast, multicast, broadcast), the first terminal may receive one or more coordination signals sent by the second terminal.
[0154] Step 202: When the first information indicates the first resource, the second terminal determines the resource type of the first resource based on the first indication information;
[0155] In the case where the second terminal sends multiple coordination signals to the first terminal, the multiple coordination signals are transmitted according to a preset timing sequence.
[0156] And / or, when the coordination signaling is a PSFCH signal used for conflict indication, the priority of the coordination signaling is determined according to preset rules.
[0157] In this embodiment, when the coordination signaling carries first information indicating a first resource, the first terminal determines the resource type and / or resource selection behavior of the transmitted resource based on the transmission type of the coordination signaling or the first indication information. Simultaneously, for the transmission of multiple coordination signals, they are transmitted according to a preset timing sequence, thus ensuring accurate and effective transmission of coordination information. When the coordination signaling is a PSFCH signal used for conflict indication, the priority of the coordination signaling is determined according to preset rules, ensuring minimal mutual interference between the coordination signaling and other signals, and protecting the effectiveness and reliability of the transmission of the coordination signaling or other more important signals.
[0158] In one possible implementation, the transmission resource is a non-preferred resource indicated by the second terminal to the first terminal; that is, there is a correlation between the coordination signaling cast type and the non-preferred resource type.
[0159] The resource types for transmission resources include one or more of the following:
[0160] (1) Type 1, used to represent non-preferred resources obtained based on the first condition;
[0161] (2) Type 2, used to represent non-preferred resources obtained based on the second condition;
[0162] (3) Type 3 is used to represent non-preferred resources obtained based on a third condition.
[0163] It should be noted that the first condition mentioned above can specifically refer to condition 1-B-1 option 1; the second condition mentioned above can specifically refer to condition 1-B-1 option 2; and the third condition mentioned above can specifically refer to condition 1-B-2. The specific methods of condition 1-B-1 option 1, condition 1-B-1 option 2, and condition 1-B-2 can be found in the corresponding descriptions above, and will not be repeated here.
[0164] In one possible implementation, there is a mapping relationship between the transmission type of the above-mentioned coordination signaling and the resource type and / or resource selection behavior.
[0165] In this embodiment, a correspondence is established between the coordination signaling cast type and the resource type of the transmission resource, creating an association between them. This allows the first terminal to determine the resource type based on the cast type, thus identifying the appropriate scenario for using the resource. Based on this mapping between the coordination signaling transmission type and the resource type and / or resource selection behavior of the transmission resource, the first terminal determines the resource type and / or resource selection behavior of the transmission resource according to the coordination signaling sent by the second terminal, thereby ensuring accurate and effective transmission of coordination information.
[0166] In one possible implementation, the correspondence between the transport type of coordination signaling and the resource type of the transport resource is agreed upon, configured, and / or pre-configured through the protocol; that is, the protocol agrees upon, configures, and / or pre-configures which one or more non-preferred resource types the cast type carries.
[0167] For example, for unicast coordination signaling or groupcast coordination signaling, only Type 1 and / or Type 3 non-preferred resources may be carried;
[0168] For example, coordination signaling for unicast or groupcast transmissions can carry all the non-preferred resources of the above types.
[0169] For example, for broadcast coordination signaling, only non-preferred resources of type 1 and / or type 2 can be carried.
[0170] In one possible implementation, the correspondence between the signaling format of coordination signaling and the resource type of the transmission resource is agreed upon, configured, and / or pre-configured through a protocol; wherein the signaling format includes at least one of MAC CE, 1st-stage SCI, and 2nd-stage SCI. That is, the signaling format carried by different types of non-preferred resources is agreed upon, configured, and / or pre-configured through a protocol to distinguish between different types of non-preferred resources.
[0171] For example: when the resource type of the first resource is Type 1 or Type 2, the coordination signaling is 1st stage SCI; that is, a non-preferred resource of Type 1 or Type 2 is indicated by a 1st stage SCI.
[0172] When the resource type of the first resource is Type 3, the coordination signaling is MAC CE or 2nd stage SCI. That is, the non-preferred resource of Type 3 is carried by MAC CE or 2nd stage SCI.
[0173] In one possible implementation, before the second terminal sends coordination signaling to the first terminal, the method further includes: the second terminal receiving a request signaling sent by the first terminal, the request signaling being used to request coordination signaling;
[0174] The request signaling or coordination signaling carries first indication information to indicate the resource type of the transmission resource. Specifically, it explicitly indicates the preferred resource type and / or non-preferred resource type contained in the coordination signaling.
[0175] Specifically, when the first resource is a non-preferred resource indicated by the second terminal to the first terminal, the resource type of the first resource includes one or more of the following:
[0176] (1) The first type is used to represent a non-preferred resource obtained based on the first condition (specifically, condition 1-B-1 option 1);
[0177] (2) The second type is used to represent a non-preferred resource obtained based on the second condition (specifically, condition 1-B-1 option 2);
[0178] (3) The third type is used to represent non-preferred resources obtained based on the third condition (specifically, condition 1-B-2);
[0179] When the first resource is a preferred resource indicated by the second terminal to the first terminal, the resource type of the first resource includes one or more of the following:
[0180] (4) The fourth type is used to represent the preferred resource obtained based on the fourth condition (specifically, condition 1-A-1);
[0181] (5) The fifth type is used to represent the preferred resource obtained based on the fifth condition (specifically, condition 1-A-2);
[0182] In one possible implementation, one or more of the following fields are jointly encoded: resource type indication field, preferred resource and non-preferred resource identifier indication field, request signaling and coordination signaling identifier indication field. That is, resource type indication, preferred resource / non-preferred resource indication, and / or request / coordination signaling indication can be jointly encoded to save signaling overhead.
[0183] For example: the indicator field can only indicate the resource type, and the preferred resource / non-preferred resource is implicitly determined based on the resource type;
[0184] For example, one code point in the indicator field indicates whether the signaling is a request signaling, while other code points are used to indicate what type of resource type the signaling carries as a coordination signaling.
[0185] Considering the same UE-B, it may receive multiple coordination signals within a certain time period. Different coordination signals may carry different information. Therefore, it is necessary to solve how the UE-B can effectively distinguish between different coordination signals in order to avoid confusion between different coordination information.
[0186] In one possible implementation, multiple coordination signaling signals are transmitted according to a preset timing sequence, including:
[0187] The first coordination signaling triggered by the request signaling sent by the first terminal among the multiple coordination signalings is sent within a preset latency bound time limit. The second coordination signaling among the multiple coordination signalings other than the first coordination signaling is sent after the preset latency bound time limit.
[0188] In the embodiments of this application, such as Figure 3aAs shown, for request-triggered coordination signaling, this signaling is sent within the latency bound after the request is received. Other coordination signals (such as condition-triggered signals) are sent after the latency bound, or after the request-triggered signaling is sent. The purpose is to avoid disrupting the correspondence between requests and their corresponding coordination signals.
[0189] Optionally, the second coordination signaling is one of those transmitted to the first terminal, or has the same destination address as the first coordination signaling, or has the same transmission type as the first coordination signaling.
[0190] Considering that UE-A and UE-B are receiving / transmitting other signals simultaneously while receiving / transmitting coordination signaling, it is necessary to solve how to ensure that the mutual interference between coordination signaling and other signals is minimal, and how to protect the effectiveness and reliability of the transmission of coordination signaling / other more important signals.
[0191] In one possible implementation, such as Figure 3b As shown, the priority of coordination signaling is determined according to preset rules, including:
[0192] When the transmission time of coordination signaling overlaps with that of the Physical Uplink Shared Channel or Physical Uplink Control Channel (PUSCH / PUCCH containing SL HARQ) that includes Hybrid Automatic Repeat Request, if priority determination is performed, the priority of coordination signaling is always lower than or no higher than the priority of PUSCH / PUCCH containing SL HARQ.
[0193] Alternatively, when the transmission time of coordination signaling overlaps with that of PUSCH / PUCCH containing SL HARQ, if priority determination is performed, the priority value of coordination signaling is always greater than or not less than the priority value of PUSCH / PUCCH containing SL HARQ.
[0194] In one possible implementation, the priority of coordination signaling is determined according to preset rules, including:
[0195] When the transmission time of coordination signaling overlaps with that of UCI (e.g., simultaneous transmission or simultaneous one-to-one transmission and one-to-reception), if priority determination is performed, the priority of coordination signaling will always be lower than or no higher than the priority of UCI.
[0196] Alternatively, when the transmission time of coordination signaling overlaps with that of UCI, if priority determination is performed, the priority value of coordination signaling will always be greater than or no less than the priority value of UCI.
[0197] Optionally, the UCI includes at least one of the following:
[0198] (1) UCI transmitted on PUCCH;

[0201] (4) UCI transmitted on PUSCH, and the UCI contains HARQ for DL transmission;
[0202] (5) UCI transmitted on a PUCCH with a preset priority index (e.g., the preset priority index is 0 or 1);
