[0019] The following clearly describes the technical solutions in the embodiments of the present application, in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application fall within the scope of protection of the present application.

[0020] The terms "first," "second," etc. in the specification and claims of this application distinguish between similar objects and do not describe a specified order or sequence. It is to be understood that terms used in this manner are interchangeable where appropriate, so that embodiments of this application may be performed in orders other than those illustrated or described herein, and that objects distinguished by "first" and "second" generally are of the same type and do not limit the number of objects; for example, a first object may be one or more. Furthermore, in the specification and claims, "and" indicates at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the related objects.

[0021] It should be noted that the techniques described in the embodiments of the present application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be applied to other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in the embodiments of the present application are always used interchangeably, and the described techniques may be used in the above-mentioned systems and radio technologies as well as other systems and radio technologies. Although the following description describes New Radio (NR) systems for illustrative purposes and uses NR terminology in most of the following description, these technologies may also be used in applications other than NR system applications, such as sixth generation (6G) systems. th This may be applied to 6G (6th Generation) communication systems.

[0022] To facilitate understanding of the embodiments of the present application, the following technical points are first introduced.

[0023] New Radio (NR) sidelink resource allocation / selection 1. There are two types of NR SL resource allocation schemes: one is based on base station scheduling (mode 1) and the other is based on terminal (e.g., user equipment (UE)) autonomous resource selection (mode 2). In the base station scheduling resource allocation scheme, the sidelink resources for UE data transmission are determined by the base station and notified to the UE for transmission (TX) via downlink signaling. In the UE autonomous selection resource allocation scheme, the UE selects available transmission resources from a (pre-configured) resource pool. Before selecting resources, the UE first performs channel monitoring and selects a resource set with relatively low interference based on the channel monitoring (sensing) results, and then randomly selects resources for transmission from the resource set.

[0024] The specific operation method for mode 2 is as follows:

[0025] 1) After resource selection is triggered, the TX UE first determines a resource selection window. The lower boundary of the resource selection window is T1 time after the resource selection trigger, and the upper boundary of the resource selection window is T2 time after the trigger. Here, T2 is the value selected within the Packet Delay Budget (PDB) to be transmitted in the Transport Block (TB) by the method implemented by the UE, and T2 is after T1.

[0026] 2) Before selecting resources, the UE must determine a candidate resource set for resource selection and compare it with a corresponding RSRP threshold based on the Reference Signal Receiving Power (RSRP) measured on resources within the resource selection window. If the RSRP is higher than the RSRP threshold, the UE performs resource exclusion on the resource and cannot include it in the candidate resource set. After resource exclusion, the resources remaining in the resource selection window constitute the candidate resource set. The proportion of resources in the candidate resource set to the resources in the resource selection window must be 20% or more. If it is less than 20%, the UE must increase the RSRP threshold by a step value (3 dB) until resources equal to or greater than 20% can be selected, and then perform the resource exclusion operation.

[0027] 3) After the candidate resource set is determined, the UE randomly selects a transmission resource in the candidate resource set, and the UE can reserve the transmission resource for the next transmission during the current transmission.

[0028] 2. Periodic-based partial sensing Periodic partial detection is suitable for a situation where the resource pool enables periodic resource reservation. When the UE performs resource selection, it needs to determine Y candidate slots (the minimum value of Y is configured / preconfigured) in the resource selection window, and each of the Y candidate slots needs to have a periodic monitoring result. SL y Suppose that t is one of the Y candidate slots. SL y It is required to monitor the first k periods of the UE to obtain periodic monitoring results. The slots that the UE needs to monitor are as follows:

[0029] TIFF2025122185000002.tif1340 where Preserve is a periodic value, and Preserve is one or more set values, which correspond to one or more integer values for each periodic value k.

[0030] 3. Contiguous (or aperiodic) partial sensing When a UE performs resource selection, it must perform continuous channel monitoring before determining a set of candidate resources. The size of the monitoring window is determined by the Tracking Area (TA) and the Time Domain (TB). When performing resource selection, the UE must consider at least one of continuous monitoring results and periodic monitoring results. The continuous partial detection mechanism also involves the location of resource selection. The resource selection window may occur after the continuous detection window, and resource selection is performed in the selection window. Alternatively, a candidate slot may occur after the continuous detection window, and resource selection is performed in the candidate slot. It should be understood that whether the location of resource selection is called a resource selection window or a candidate slot, there is no essential difference between them, as both limit the time location where resource selection can occur.

[0031] Referring to FIG. 1, a block diagram of a wireless communication system to which the embodiment of the present application can be applied is shown. The wireless communication system includes a terminal A11, a terminal B12, and a network side device 13. Here, the terminal may be referred to as a terminal device or user equipment (UE), and the terminal may be a terminal side device such as a mobile phone, a tablet personal computer (PDA), a laptop computer (also called a notebook computer), a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), a wearable device, a vehicle-mounted equipment (VUE), a pedestrian-mounted equipment (PUE), etc., and the wearable device includes a smart watch, a bracelet, an earphone, glasses, etc. It should be noted that the embodiment of the present application does not limit the specific types of the terminal A11 and the terminal B12.

[0032] The network side device 13 may be a base station or a core network. Here, the base station may be referred to as a Node B, an evolved Node B, an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a B node, an evolved B node (gNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting and receiving point (TRP), a radio access network node, or any other appropriate term in the art. As long as the same technical effect is achieved, the base station is not limited to the specified technical term. It should be noted that the embodiments of this application only take base stations in an NR system as examples, and do not limit the specific type of base station.

[0033] Referring to FIG. 2, an embodiment of the present application provides a resource recommendation method, and specific steps include step 201.

[0034] Step 201: A first terminal determines a recommended resource to be recommended to a second terminal; wherein the recommended resource is: (1) a monitoring result of the first terminal; (2) a transmission resource of the first terminal; (3) a receiving resource of the first terminal; (4) a resource that the first terminal recommends to a third terminal; and / or The first terminal transmits first information to the second terminal, the first information including related information of the recommended resource and / or second information, and the second information indicates whether the recommended resource is for the second terminal to transmit to the first terminal.

[0035] The embodiments of this application include the following three solutions:

[0036] Scheme 1: The first terminal determines the recommended resources to recommend to the second terminal.

[0037] Method 2: The first terminal sends first information to the second terminal, the first information including related information of the recommended resource and / or second information, and the second information indicates whether the recommended resource is intended for the second terminal to transmit to the first terminal.

[0038] Method 3: The first terminal determines recommended resources to recommend to the second terminal, and the first terminal sends first information to the second terminal, where the first information includes related information of the recommended resources and / or second information, and the second information indicates whether the recommended resources are intended for the second terminal to transmit to the first terminal.

[0039] As can be understood, the first terminal notifies the second terminal, through the first information, whether the resources it recommends are likely to be used (tend to be used) by the second terminal for transmission to the first terminal. For example, the first information may carry a label (flag). For example, a label of "1" indicates that the resources recommended by the first terminal can be used by the second terminal for transmission to the first terminal, and a label of "0" indicates that the resources recommended by the first terminal cannot be used by the second terminal for transmission to the first terminal. Alternatively, if the first information carries the ID of the first terminal, it indicates that the resources recommended by the first terminal can be used by the second terminal for transmission to the first terminal, and if the ID of the first terminal is not carried in the first information, it indicates that the resources recommended by the first terminal cannot be used by the second terminal for transmission to the first terminal. In this way, when the first terminal is a receiving (RX) UE, it can optimize resource recommendation taking into account more factors and avoid resource collision problems for the first terminal.

[0040] In one embodiment of the present application, the step of the first terminal determining recommended resources to recommend to the second terminal includes a step of the first terminal determining an application scenario, and a step of determining whether the first terminal can determine recommended resources to recommend to the second terminal according to the application scenario.

[0041] Here, the application scenario may include one or more of a scenario in which the second terminal does not have sensing capability, a scenario in which the first terminal schedules the second terminal, a scenario in which the first terminal has complete control over the recommended resources, a scenario in which the first terminal is the receiving end of the second terminal, etc.

[0042] As can be seen, whether the first terminal uses certain factors to determine the recommended resources may be determined according to the application scenario of the recommended resources, thus improving the accuracy of the recommended resources and ensuring the transmission performance of the system.

[0043] In one embodiment of the present application, the step of determining a recommended resource recommended by the first terminal to the second terminal includes: The first terminal determines a first resource based on the monitoring result of the first terminal, where the interference value of the first resource is lower than a first threshold; and determining the recommended resource from the first resource by the first terminal.

[0044] It should be clarified that an interference value herein may be understood as an energy measurement, and a recommended resource herein may be understood as a recommended resource set.

[0045] In one embodiment of the present application, the method comprises: The method further includes a step of the first terminal transmitting to the second terminal third information indicating whether the first terminal identified the first resource when determining the recommended resource.

[0046] In one embodiment of the present application, if the recommended resource is related to the monitoring result of the first terminal, The first terminal determines an application scenario based on the fourth information, and the first terminal determines whether it can determine a recommended resource (or determine a first resource) based on the monitoring result of the first terminal according to the application scenario.

[0047] Here, the fourth information is (1) a configuration or pre-configuration of a resource pool in which the recommended resources of the first terminal are located; (2) whether the second terminal is monitoring or has monitoring capabilities; (3) whether there is a monitoring result in the second terminal that satisfies a preset condition; and (4) an interference situation of a resource pool in which the recommended resource of the first terminal is located; (5) a result of the negotiation between the first terminal and the second terminal; and (6) information configured or pre-configured by the control node; (7) information autonomously determined by the first terminal; and (8) the distance between the first terminal and the second terminal; and (9) a measurement value between the first terminal and the second terminal.

[0048] In one embodiment of the present application, the method comprises: The method further includes a step in which the first terminal receives fifth information from the second terminal, the fifth information indicating whether the second terminal is monitoring or has a monitoring capability, and / or whether the second terminal has a monitoring result that satisfies a preset condition.

[0049] In one embodiment of the present application, the monitoring results that satisfy the preset conditions are: (1) a complete monitoring result required for the second terminal to obtain a resource selection flow; (2) The second terminal includes one or more of periodic or aperiodic partial monitoring results corresponding to target candidate slots that can be obtained based on partial sensing based resource selection.

[0050] In one embodiment of the present application, the periodic portion monitoring result includes the second terminal obtaining, through periodic portion monitoring, monitoring results corresponding to all or part of the periodic reservations configured by the resource pool, or the second terminal obtaining, through periodic portion monitoring, monitoring results corresponding to the periodic reservations required for this resource flow; Or, The non-periodic portion monitoring result includes the second terminal obtaining, through non-periodic portion monitoring, monitoring results corresponding to all or part of the non-periodic reservations configured by the resource pool, or the second terminal obtaining, through non-periodic portion monitoring, monitoring results corresponding to the non-periodic reservations required for this resource flow.

[0051] As can be appreciated, the required periodic reservations may be configured or pre-configured by the control node or may be negotiated by a protocol, and the required aperiodic reservations may be configured or pre-configured by the control node or may be negotiated by a protocol.

[0052] In one embodiment of the present application, the number of target candidate slots is stipulated by a protocol and configured or pre-configured by a control node.

[0053] In one embodiment of the present application, the step of determining a recommended resource recommended by the first terminal to the second terminal includes: The first terminal determines a target resource window that does not include resources related to the transmission resources and / or reception resources of the first terminal, the first terminal obtains second resources in the target resource window based on a monitoring result, and the first terminal selects the recommended resources from the second resources; Or, The first terminal acquires second resources within a preset resource window based on a monitoring result, the first terminal acquires third resources by excluding resources related to the transmission resources and / or reception resources of the first terminal from the second resources, and the first terminal selects the recommended resources from the third resources; Here, the interference value of the second resource is lower than a second threshold.

[0054] In one embodiment of the present application, a method comprises: The method further includes a step of the first terminal transmitting sixth information to the second terminal, the sixth information indicating whether the first terminal excluded resources related to the transmission resources and / or reception resources of the first terminal when selecting the recommended resources.

[0055] As can be understood, the sixth information and the first information may be the same or different information, and if the sixth information and the first information are the same information, in step 201, the first terminal indicates whether the first terminal has excluded resources related to the transmission resources and / or reception resources of the first terminal when selecting recommended resources using the first information.

[0056] In one embodiment of the present application, when the recommended resources are related to the transmission resources and / or reception resources of the first terminal, the first terminal determines an application scenario based on the seventh information, and the first terminal determines whether it can determine the recommended resources based on the transmission resources and / or reception resources of the first terminal according to the application scenario; Here, the seventh information is (1) a result of negotiation between the first terminal and the second terminal; (2) information configured or pre-configured by the control node; (3) Information autonomously determined by the first terminal.

[0057] In one embodiment of the present application, when the recommended resource is related to a resource that the first terminal recommends to a third terminal, the first terminal determines an application scenario based on eighth information, and the first terminal determines whether the recommended resource can be determined based on the resource that the first terminal recommends to a third terminal according to the application scenario; Here, the eighth information indicates a relationship between the first terminal and the second terminal, for example, the first terminal is a sublink relay terminal (SL relay UE), a group header terminal, or a road side unit (RSU), etc.

[0058] In an embodiment of the present application, the first terminal determines recommended resources to be recommended to the second terminal based on various different factors, thereby improving the accuracy of the recommended resources and ensuring the transmission performance of the system. Furthermore, the first terminal can transmit first information to the second terminal, where the first information includes related information of the recommended resources and / or second information, and the second information indicates whether the recommended resources are intended for transmission by the second terminal to the first terminal. In this way, when the first terminal is the receiving terminal, the resource recommendation can be optimized by taking into account more factors and avoiding resource collision problems.

[0059] Referring to FIG. 3, an embodiment of the present application provides a method for determining transmission resources, and specific steps include step 301.

[0060] Step 301: A second terminal receives first information, the first information including related information of a recommended resource and / or second information, and the second information indicates whether the recommended resource is for the second terminal to transmit to the first terminal; Step 302: The second terminal selects a transmission resource from the fourth resource and / or the fifth resource; Here, the fourth resource includes a resource whose interference value in the recommended resource is lower than a third threshold, and the fifth resource includes a resource monitored by the second terminal whose interference value is lower than a fourth threshold.

[0061] Here, the fourth resource may be referred to as a low-interference recommended resource, and the fifth resource may be referred to as a low-interference resource monitored by the second terminal.

[0062] In one embodiment, the recommended resources mentioned in the first information may be determined by the first terminal based on one or more of: (1) monitoring results of the first terminal; (2) transmission resources of the first terminal; (3) reception resources of the first terminal; and (4) resources recommended by the first terminal to a third terminal other than the second terminal.

[0063] In another embodiment, the recommended resources mentioned in the first information may be determined by the first terminal based on factors other than (1) to (4) above, that is, in this embodiment, there are no specific limitations on the factors for determining the recommended resources recommended by the first terminal.

[0064] As can be understood, the second terminal may select a transmission resource from the low-interference resources recommended by the first terminal, or may select a transmission resource based on the low-interference resources monitored by itself, thereby satisfying that the second terminal can select an appropriate transmission resource according to different UE cooperation scenarios.

[0065] Furthermore, since the second information indicates whether the recommended resource is for the second terminal to transmit to the first terminal, when the first terminal is thus set as the receiving terminal, the resource recommendation can be optimized taking into account more factors and the problem of resource collision can be avoided.

[0066] In one embodiment of the present application, the step of the second terminal selecting a transmission resource based on the fourth resource includes: the second terminal determining whether the interference value of the recommended resource is lower than a third threshold; If the interference value of the recommended resource is lower than a third threshold, the second terminal randomly selects a transmission resource from resources whose interference value in the recommended resource is lower than a third threshold, or selects a transmission resource based on an action implemented by the second terminal.

[0067] In one embodiment of the present application, the step of determining by the second terminal whether the interference value of the recommended resource is lower than a third threshold includes: The second terminal determines a candidate resource set based on a monitoring result, and if the recommended resource is located in the candidate resource set, the second terminal determines that the interference value of the recommended resource is lower than a third threshold; Or, The method includes the step of the second terminal determining that an interference value of the recommended resource is lower than a third threshold if the measurement value associated with the recommended resource is lower than a fourth threshold.

[0068] Optionally, the measurement is RSRP or the like.

[0069] In one embodiment of the present application, the step of determining a candidate resource set based on a monitoring result by the second terminal includes: a physical layer of the second terminal determining a candidate resource set based on a monitoring result; When the recommended resource is located in the candidate resource set, the step of the second terminal determining that the interference value of the recommended resource is lower than a third threshold value includes: If the recommended resource is located in the candidate resource set, the second terminal determines that an interference value of the recommended resource is lower than a third threshold.

[0070] In one embodiment of the present application, the fourth threshold is agreed upon by a protocol, or configured or pre-configured by a control node, or the fourth threshold is determined based on a candidate resource set, or the fourth threshold is determined based on a candidate resource set and an offset value, or the fourth threshold is the average value of measurement values on x% of resources with the highest / lowest measurement values, or the fourth threshold is the minimum value among the threshold values obtained based on the above multiple threshold determination methods.

[0071] In one embodiment of the present application, the step of determining a candidate resource set based on a monitoring result by the second terminal includes: the second terminal adjusting a measurement threshold on the recommended resource in a resource selection window; determining a candidate resource set based on the monitoring results and the measurement thresholds.

[0072] In one embodiment of the present application, the step of the second terminal obtaining recommended resources recommended by the first terminal includes: The second terminal obtains recommended resources recommended by the first terminal through a Medium Access Control (MAC) layer; The MAC layer of the second terminal notifies the physical layer of the recommended resources.

[0073] Specifically, when the recommended resources are carried by a MAC CE, after the second terminal decodes the MAC CE, the MAC layer notifies the recommended resources to the physical layer, and the physical layer performs interference judgment on the recommended resources, or the physical layer reports the obtained low-interference resource set to the MAC layer, and the MAC layer judges whether the recommended resources belong to the low-interference resource set.

[0074] In one embodiment of the present application, the step of the second terminal selecting a transmission resource from the fourth resource and the fifth resource includes: The second terminal selects M resources from the fourth resources and N resources from the fifth resources, and the transmission resources include the M resources and the N resources; Here, M and N are equal to or greater than 0.

[0076] In one embodiment of the present application, the possible values of M or N are agreed upon by a protocol, or configured or pre-configured by a control node, or autonomously determined by the second terminal, or determined based on a priority by which the second terminal selects resources from the fourth resource and the fifth resource.

[0077] In one embodiment of the present application, the priority in which the second terminal selects a resource from the fourth resource and the fifth resource is agreed upon by a protocol, or is configured or pre-configured by a control node.

[0078] In one embodiment of the present application, the step of selecting M resources or N resources includes the step of randomly selecting M resources from the fourth resource or randomly selecting N resources from the fifth resource.

[0079] In one embodiment of the present application, the step of the second terminal selecting a transmission resource from the fourth resource and the fifth resource includes: The second terminal may aggregate the fourth resource and the fifth resource and select a transmission resource from the aggregated resource.

[0080] In one embodiment of the present application, the step of selecting a transmission resource from the aggregated resources comprises: The second terminal selects a transmission resource from the aggregated resources based on a preset priority; Here, the preset priority includes the second terminal preferentially selecting a transmission resource from the fourth resource.

[0081] In one embodiment of the present application, the method comprises: The second terminal further includes determining whether to combine the monitoring result of the second terminal when selecting the transmission resource based on ninth information; Here, the ninth information is: (1) a configuration or pre-configuration of a resource pool in which the recommended resource is located; and (2) the interference situation of the resource pool in which the recommended resource is located; (3) a negotiation result between the first terminal and the second terminal; (4) whether the second terminal is monitoring or has the capability to monitor; (5) whether there are sufficient monitoring results on the second terminal; and (6) information configured or pre-configured by the control node; (7) information autonomously determined by the second terminal; and (8) the distance between the first terminal and the second terminal; (9) measurements between the first terminal and the second terminal; and (10) The number of candidate resources for the second terminal.

[0082] In one embodiment of the present application, the method comprises: The method further includes determining, by the second terminal, whether to combine the recommended resources when selecting the transmission resources based on tenth information; Here, the tenth information indicates the number of candidate resources for the second terminal.

[0083] For example, if the number of candidate resources of the second terminal is smaller than a preset threshold, the second terminal needs to combine the recommended resources when selecting the transmission resources.

[0084] In the embodiments of the present application, the second terminal may select a transmission resource from the low-interference resources recommended by the first terminal, or may select a transmission resource based on the low-interference resources monitored by itself, thereby ensuring the transmission reliability and availability of the second terminal in various terminal cooperation scenarios.

[0085] Referring to FIG. 4, the specific steps include:

[0086] Step 401: A first terminal determines a recommended resource to be recommended to a second terminal.

[0087] Step 402: The first terminal sends first information to the second terminal, where the first information includes related information of a recommended resource and / or second information, and the second information indicates whether the recommended resource is for the second terminal to transmit to the first terminal.

[0088] Step 403: The second terminal selects a transmission resource from the fourth resource and / or the fifth resource.

[0089] Here, the fourth resource includes a resource whose interference value in the recommended resource is lower than a third threshold, and the fifth resource includes a resource monitored by the second terminal whose interference value is lower than a fourth threshold.

[0090] For understanding, the description of steps 401 to 403 can be referred to the introduction of the corresponding steps in the method embodiments shown in FIGS.

[0091] The following will be described as an example in which the first terminal is UE-A and the second terminal is UE-B.

[0092] 1. Introduction to the determination of recommended resources by UE-A.

[0093] UE-A determines the recommended resources through one or more of the following methods 1 to 3:

[0094] Scheme 1: UE-A identifies low-interference resources based at least on the sensing result, and selects recommended resources from the identified low-interference resources.

[0095] For example, UE-A acquires low interference resources in a preset resource window based on the sensing result.

[0096] Option 1: UE-A determines the candidate resource set according to its channel monitoring result, and determines that a resource is a low-interference resource if it is included in the candidate resource set.

[0097] Optionally, in identifying the candidate resource set, UE-A may not exclude periodic slots corresponding to slots not monitored by UE-A. For example, if slot n is a slot not monitored by UE-A, UE-A may not exclude slots n+P, n+2*P, ..., n+K*P when performing resource exclusion, where n+K*P are periodically reserved slots, P is the reservation period, and K is an integer.

[0098] Option 2: If the RSRP measurement value associated with the resource is lower than the RSRP threshold, the resource is determined to be a low interference resource.

[0099] Optionally, the RSRP threshold is a value that is agreed upon by the protocol, pre-configured, or configured by the control node.

[0100] Optionally, the RSRP threshold is an RSRP threshold determined based on the candidate resource set (optionally, the RSRP threshold is an RSRP threshold associated with the priority of the transmission TB).

[0101] Optionally, the RSRP threshold is the average value of the RSRP measurements on the x% of resources with the highest / lowest RSRP measurements.

[0102] Optionally, it determines whether to identify a low interference resource based on the sensing result based on one or more of factors 1 to 8.

[0103] Factor 1: Based on the configuration or pre-configuration of the resource pool in which the recommended resource of UE-A is located.

[0104] For example, if the resources of a resource pool are completely dominated by UE-A and there are no other nodes that cause strong interference to the resource pool, UE-A does not need to identify low-interference resources.

[0105] Factor 2: Based on whether UE-B is sensing (capable) and / or whether UE-B has sufficient sensing results. For example, if UE-B is not sensing, UE-A may sense to supplement UE-B's sensing, and if UE-B is sensing, UE-A may not identify low-interference resources.

[0106] UE-B may report to UE-A whether UE-B is capable of sensing and / or whether UE-B has sufficient sensing results.

[0107] Here, the meaning of the sufficient sensing result includes one or more of the following:

[0108] (a) Based on the sensing-based resource selection flow in the related art, the UE can obtain the required complete sensing results.

[0109] (b) Based on the partial sensing based resource selection flow in the related art, the UE can obtain a partial sensing result corresponding to a target candidate slot.

[0110] Option 1: The corresponding periodic partial sensing and / or aperiodic partial sensing results meet the partial sensing requirements in the related art.

[0111] Option 2: Periodic partial sensing can provide sensing results corresponding to all periodic reservations configured by the resource pool (or some of those contracted / configured / pre-configured by the protocol).

[0112] Option 3: Aperiodic partial sensing can provide sensing results corresponding to all (or some of) the aperiodic reservations agreed / configured / pre-configured by the protocol.

[0113] Optionally, the number of target candidate slots is stipulated by a protocol and meets configured or pre-configured requirements.

[0114] Factor 3: Based on the interference situation of the resource pool where the recommended resource is located.

[0115] For example, if the CBR of the resource pool is higher than a predetermined threshold, UE-A does not need to identify low interference resources.

[0116] Factor 4: Determined based on negotiation between UE-A and UE-B.

[0117] For example, UE-B requests transmission resources from UE-A, and the resources are for transmission from UE-B to UE-A (the transmission type may be further limited to one or more of unicast, groupcast, and broadcast), and UE-A needs to identify low-interference resources to avoid the hidden node problem, and for example, UE-B directly instructs UE-A to identify low-interference resources based on its sensing results.

[0118] Factor 5: Pre-configuration / based on the configuration of the control node at the control point, e.g., per-UE or per-pool configuration, by which the network controls the application scenario.

[0119] Factor 6: Based on UE-A's autonomous decision.

[0120] Factor 7: Determine based on the distance between UE-A and UE-B.

[0121] For example, if the distance is greater than a preset value, UE-A does not need to identify low interference resources, and otherwise it does.

[0122] Factor 8: Determine based on RSRP measurements between UE-A and UE-B.

[0123] For example, if the RSRP measurement value is smaller than a preset value, UE-A does not need to identify a low interference resource, and otherwise it does.

[0124] Optionally, whether UE-A has performed low-interference resource identification when selecting the recommended resource may be notified to UE-B, for example, in the auxiliary information or by separate signaling.

[0125] Scheme 2: UE-A determines the recommended resources based at least on the transmitting and receiving resources (including the transmitting resources and / or the receiving resources) of UE-A.

[0126] Optionally, the transmission and reception resources of UE-A are: (1) Time-frequency resources received by the NR Physical Sidelink Shared Channel (PSSCH); (2) Time domain resources transmitted by NR PSSCH; (3) Time domain resources transmitted / received by the NR physical sidelink feedback channel (PSFCH); (4) Time domain resources for UE-A's uplink transmission; (5) Time domain resources transmitted / received by LTE PSSCH; Alternatively, the relationship between the transmission / reception resources of UE-A and the resources that UE-A wishes to recommend may be embodied in the following manner:

[0127] (1) There is a half-duplex restriction / simultaneous transmission restriction in the frequency band where the transmission / reception resource of UE-A and the resource that UE-A wants to recommend are located, (2) The transmission and reception resources of UE-A overlap with the PSCCH or PSSCH resource that UE-A wishes to recommend, or with the PSFCH resource corresponding to the PSCCH or PSSCH resource that UE-A wishes to recommend.

[0128] Optionally, determining recommended resources based on the transmitting and receiving resources of UE-A includes one or more of the following:

[0129] Option 1: UE-A acquires low-interference resources within a preset resource window based on the sensing result, excludes resources related to UE-A's transmission and reception resources before acquiring the low-interference resources, and then selects recommended resources from the low-interference resources.

[0130] In this way, it is possible to avoid collision between low-interference resources and UE-A's transmission / reception resources, and ensure sufficient selectable resources.

[0131] Option 2: UE-A acquires low-interference resources within a preset resource window based on the sensing result, and after acquiring the low-interference resources, excludes resources related to UE-A's transmission and reception resources, and then selects recommended resources from among them.

[0132] In this way, the acquisition flow of low interference resources can be simplified, and the recommended resource selection of UE-A has more flexibility.

[0133] As can be appreciated, the identification of low interference resources is a matter of choice.

[0134] Optionally, determine whether to determine the recommended resource based on the transmitting and receiving resource of UE-A according to one or more of the following factors 1 to 3:

[0135] Factor 1: Determined based on negotiation between UE-A and UE-B.

[0136] For example, UE-B requests transmission resources from UE-A, and the resources are for transmission from UE-B to UE-A (the transmission type may be further limited to one or more of unicast, groupcast, and broadcast), and UE-A determines recommended resources based on its transmitting and receiving resources to avoid problems such as half-duplex collision / simultaneous transmission collision.

[0137] Factor 2: Based on the configuration of the control node at the pre-configuration / control point.

[0138] For example, per-UE or per-pool configuration, whereby the network performs corresponding control according to the application scenario.

[0139] Factor 3: Decide based on UE-A realization.

[0140] Optionally, UE-A may notify UE-B whether resources related to the UE-A's transmission / reception resources have been excluded when selecting the recommended resources, for example, in the auxiliary information or by separate signaling.

[0141] Scheme 3: UE-A determines the recommended resources based at least on the resources that UE-A recommends to other UE-B.

[0142] Alternatively, the UE-A determines whether to recommend resources based on the resources recommended by the UE-A to another UE-B based on the following factor 1:

[0143] Factor 1: Based on the relationship between UE-A and UE-B.

[0144] For example, if UE-A is an SL relay UE, a group header UE, or an RSU (road side unit), and UE-A is associated with multiple UE-Bs, UE-A determines the recommended resources based on the resources that UE-A recommends to other UE-Bs.

[0145] Alternatively, whether the resources recommended by UE-A are likely to be used for transmission from UE-B to UE-A may be indicated to UE-B, for example, by a label (flag) or by the UE ID of UE-A.

[0146] In this way, UE-A, as a RX UE, can optimize resource recommendation by considering more factors and avoid resource collision problems for UE-A.

[0147] 2. Introduction to the selection of transmission resources by UE-B.

[0148] UE-B obtains the recommended resources and determines the interference on the recommended resources based on its own monitoring results (e.g., analyzes the interference on the recommended resources from the TX UE perspective), and UE-B selects a transmission resource from the recommended resources with low interference.

[0149] Optionally, the manner of determining the low interference resource includes one or more of the following:

[0150] Option 1: UE-B determines the candidate resource set according to its channel monitoring results, and if the recommended resource is included in the candidate resource set, it determines that the recommended resource is a low-interference resource.

[0151] Option 2: If the RSRP measurement value associated with the recommended resource is lower than the RSRP threshold, determine that the recommended resource is a low interference resource.

[0152] Alternatively, the RSRP threshold may be a value that is agreed upon by the protocol, pre-configured, or configured by the control node.

[0153] Alternatively, the RSRP threshold may be an RSRP threshold determined based on a candidate resource set (e.g., the RSRP threshold is an RSRP threshold associated with the priority of a Transport Block (TB)), or a threshold plus an offset value.

[0154] Optionally, the RSRP threshold is the average value of the RSRP measurements on the x% of resources with the highest / lowest RSRP measurements.

[0155] Optionally, for determining the candidate resource set according to the alternative method 1 or the alternative method 2, a conventional candidate resource set determination method or an enhanced candidate resource set determination method may be adopted.

[0156] Alternatively, the candidate resource set may be referred to as a set of low interference resources monitored by UE-B.

[0157] Optionally, the enhanced candidate resource set determination scheme includes adjusting the RSRP and / or RSRP threshold on the recommended resources in the resource selection window, for example, increasing / decreasing the RSRP and / or RSRP threshold.

[0158] Alternatively, if the recommended resources are obtained by decoding by a MAC control unit (Control Element, CE), the MAC layer notifies the recommended resources to the physical layer to perform interference determination, or the physical layer (Physical Layer, PHY) layer reports the low-interference resource set obtained by sensing to the MAC layer, and the MAC layer determines whether the recommended resources belong to the low-interference resource set.

[0159] Selectively selecting a transmission resource from the low-interference recommended resources includes: The method further includes selecting a transmission resource from the low-interference recommended resources and / or the low-interference resources monitored by the UE-B.

[0160] Option 1: Select transmission resources from the low-interference recommended resources and the monitored low-interference resources respectively (i.e., if the number of transmission resources is N, select M transmission resources from the low-interference recommended resources and select NM resources from the monitored low-interference resources).

[0161] Optionally, the order of selecting transmission resources from the low-interference recommended resources and the monitored low-interference resources is a preset order, for example, selecting from the low-interference recommended resources first, and the preset order is an order configured or pre-configured by the control node.

[0162] Alternatively, M may be determined by the UE implementation, or M may be determined based on the resource selection order.

[0163] For example, the UE preferentially selects transmission resources from the recommended resources with low interference, and if the recommended resources with low interference are insufficient, selects transmission resources from the monitored low-interference resources; or the UE preferentially selects transmission resources from the recommended resources that are monitored, and if the monitored recommended resources are insufficient, selects transmission resources from the recommended resources with low interference.

[0164] For example, the UE preferentially selects a transmission resource from the union of the low-interference recommended resource and the monitored low-interference resource; if there is a resource shortage, the UE selects a transmission resource from the remaining low-interference recommended resource; if there is still a resource shortage, the UE selects a transmission resource from the monitored low-interference resource; Alternatively, the UE preferentially selects a transmission resource from the union of the low-interference recommended resources and the monitored low-interference resources, and if there are insufficient resources, selects a transmission resource from the monitored low-interference resources, and if there are still insufficient resources, selects a transmission resource from the remaining low-interference recommended resources.

[0165] Optionally, the selection of the M resources and / or the NM resources is a random resource selection.

[0166] Optionally, the selected transmission resources satisfy a predetermined relationship, for example, a resource pitch smaller than 32 slots, a Hybrid Automatic Repeat Request (HARQ) Round-Trip Time (RTT) pitch, etc. As can be understood, the monitored low-interference resources may be the monitored low-interference resources remaining after excluding low-interference recommended resources.

[0167] Option 2: The recommended low-interference resources and the monitored low-interference resources are integrated to select the transmission resources.

[0168] Alternatively, the UE may preferentially select a transmission resource from the recommended resources with low interference, for example, the probability of selecting the resource is x% higher than other resources.

[0169] Optionally, the ratio of transmission resources selected from the recommended resources is agreed upon by the protocol / configured / pre-configured by the control node.

[0170] Optionally, whether UE-B associates its own sensing results depends on one or more of factors 1 to 8.

[0171] Factor 1: Based on the configuration / pre-configuration of the resource pool where UE-A's recommended resource is located.

[0172] For example, if the resources of the resource pool are completely dominated by UE-A and there are no other nodes that cause strong interference to the resource pool, UE-B does not need to make resource selection in conjunction with its own sensing results.

[0173] Factor 2: Based on the interference situation in the resource pool where the recommended resource is located.

[0174] For example, if the CBR of the resource pool is higher than a predetermined threshold, UE-A does not need to identify low interference resources.

[0175] Factor 3: Determined based on negotiation between UE-A and UE-B.

[0176] For example, if UE-A did not identify a low interference resource when selecting a recommended resource, UE-B needs to identify a low interference resource to avoid resource collision.

[0177] Factor 4: Based on whether UE-B is sensing (capable) / based on whether UE-B has sufficient sensing results.

[0178] For example, when UE-B is sensing, UE-B needs to select a transmission resource from the recommended resources with low interference in combination with its own sensing result, otherwise there is no need.

[0179] Factor 4: Based on the configuration of the control node at the pre-configuration / control point.

[0180] For example, per-UE or per-pool configuration, whereby the network performs corresponding control according to application scenarios.

[0181] Factor 5: Decide based on UE-B implementation.

[0182] Factor 6: Based on the distance (or RSRP measurement) between UE-A and UE-B.

[0183] For example, if the distance is greater than a preset value (or the RSRP measurement value is less than a preset value), UE-B needs to select from the recommended resources with low interference in conjunction with its own sensing results; otherwise, there is no need.

[0184] The distance being relatively close means that the similarity between the sensing result of UE-A and the sensing result of UE-B is relatively high.

[0185] Factor 7: Determined based on RSRP measurements between UE-A and UE-B.

[0186] For example, if the RSRP measurement value is smaller than a preset value, UE-B needs to select from the recommended resources with low interference in conjunction with its own sensing result; otherwise, it does not need to.

[0187] Factor 8: Determine based on the number of UE-B candidate resources.

[0188] For example, if the number of candidate resources of UE-B is smaller than a preset threshold, there is no need to associate its own sensing result.

[0189] Optionally, whether UE-B binds the recommended resources depends on the following factor 1.

[0190] Factor 1: Determine based on the number of UE-B candidate resources.

[0191] For example, if the number of UE-B candidate resources is smaller than a preset threshold, the UE-B needs to perform transmission resource selection by combining the recommended resources.
