Description

Technical Field

[0001] This application belongs to the field of wireless communication technology, specifically relating to a resource selection method, apparatus, and communication equipment. Background Technology

[0002] For enhanced sidelink resource selection, the following can be considered: the receiving (RX) user equipment (UE) recommends resources to the transmitting (TX) UE, and the TX UE uses the recommended resources for transmission; or the RX UE recommends resources that are unfavorable to transmission to the TX UE, and the TX UE excludes these resources during resource selection; or the UE responsible for resource coordination or scheduling, i.e., the resource coordination or scheduling UE (Co-UE), recommends resources to another UE (e.g., the TX UE), and the TX UE uses the recommended resources for transmission or excludes the resources during resource selection.

[0003] For the above scenario, the TX UE needs to send a request message to the RX UE or the UE responsible for coordination (Co-UE). After receiving the request message, the RX UE or Co-UE selects resources and informs the TX UE of the resources that meet and / or do not meet the requirements via signaling. However, if an RX UE or Co-UE receives request messages from multiple UEs within a certain period of time or simultaneously, there is currently no effective solution for determining the order, priority, or weight of resource recommendation, scheduling, or selection for different UEs.

[0029] The technical solutions provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0030] Figure 2 This diagram illustrates a flowchart of a resource selection method according to an embodiment of this application. This method 200 can be executed by a first communication device. In other words, the method can be executed by software or hardware installed on the first communication device. Figure 2 As shown, the method may include the following steps.

[0031] S210, the first communication device receives at least one first message.

[0032] In this embodiment of the application, the first information may include one of the following:

[0033] (1) Resource recommendation request information; This request information can be used to request the first communication device to recommend resources for the second communication device.

[0034] (2) Resource scheduling request information; This request information can be used to request the first communication device to schedule resources for the second communication device.

[0035] (3) Resource selection request information; This request information can be used to request the first communication device to select or reserve resources for the second communication.

[0036] (4) Buffer Status Report (BSR) information. BSR information is used to notify the first communication device of the amount of uplink resources that need to be allocated to the second communication device.

[0037] (5) Scheduling Request (SR information). SR information is used to indicate to the first communication device whether the second communication device has a resource request.

[0038] (6) Resource recommendation trigger information. The resource recommendation trigger information can trigger the first communication device to recommend resources for the second communication device.

[0039] (7) Resource scheduling trigger information. The resource scheduling trigger information can trigger the first communication device to perform resource scheduling for the second communication device.

[0040] (8) Resource selection trigger information; This request information can be used to request the first communication device to select or reserve resources for the second communication.

[0041] In the embodiments of this application, the first communication device can be a terminal or a control node. The terminal can be an RXUE, a TX UE, or a Co-UE (resource coordination or scheduling UE), and the control node can be a base station, a roadside unit (RSU), or a relay node. For example, in... Figure 3 In the process, multiple TX UEs send resource recommendation requests to RX UEs. Figure 4 In this process, multiple TX UEs send resource recommendation requests to the Co-UE.

[0042] S212, determine a first target value for at least one second communication device based on the first parameter; wherein the second communication device is the sender of the first information and / or the receiver of the second information.

[0043] In this embodiment of the application, the second communication device can be a sender of the first information and / or a receiver of the second information. In this embodiment of the application, the sender of the first information and the receiver of the second information can be the same. For example, Figure 3 or Figure 4 In this process, TX UE 1 sends a resource recommendation request to RX UE or Co-UE. After RX UE or Co-UE determines the resources to recommend to TX UE 1, it sends second information (e.g., recommended resource information) to TX UE 1. Alternatively, the sender of the first information and the receiver of the second information can be different, for example, in... Figure 4 In this process, TX UE1 requests resources from Co-UE for communication transmission with RX UE2. Co-UE can determine the first target value of RX UE2 and can send second information to RX UE2, such as recommended resource information, i.e., TX UE1 is the sender of the first information and RX UE2 is the receiver of the second information. Alternatively, both TX UE1 and RX UE2 can be receivers of the second information, i.e., Co-UE can send the second information to both TX UE1 and RX UE2.

[0044] In the embodiments of this application, a second communication device may correspond to a first piece of information, that is, a first piece of information corresponds to a second communication device.

[0045] In this embodiment of the application, the second information can be at least one of the following:

[0046] (1) Resource recommendation information; This resource recommendation information can be used to indicate resources recommended for use by the second communication device, or it can be used to indicate resources not recommended for use by the second communication device.

[0047] (2) Resource scheduling information; This resource scheduling information can be used to indicate the resources that the second communication device can use, or it can be used to indicate the resources that the second communication device cannot use.

[0048] (3) Auxiliary information. This auxiliary information may be resource location information, which is used to indicate the resources that the second communication device can use or the resources that the second communication device cannot use.

[0049] (4) Resource selection information; This resource selection information can be used to indicate the resources that the second communication device can use, or it can be used to indicate the resources that the second communication device cannot use.

[0050] In this application embodiment, the first target value can be used to determine the order, weight, or priority of resource selection for the at least one second communication device, resource scheduling for the at least one second communication device, or resource recommendation for the at least one second communication device. The first target value can also determine the order, weight, or priority of the first communication device transmitting second information to multiple second communication devices.

[0051] In one alternative implementation, the first parameter may include at least one of the following (1) to (11).

[0052] (1) Quality of Service (QoS) parameters of the services that the second communication device needs to transmit.

[0053] Optionally, the QoS parameters may include at least one of the following (a) to (e):

[0054] (a) Service Priority. For example, the services that the second communication device needs to transmit can be sorted in ascending or descending order, and the first target value of the second communication device (i.e., the order, priority, or weight of resource selection, recommendation, or scheduling by the first communication device for the second communication device) can be determined based on the sorting result. For example, the higher the service priority, the higher the priority or weight of resource selection, recommendation, or scheduling by the first communication device for the second communication device, or vice versa.

[0055] (b) Service latency requirements. For example, the service latency requirements of the services that the second communication device needs to transmit can be sorted in ascending or descending order, and the first target value of the second communication device can be determined based on the sorting result (i.e., the order, priority, or weight of resource selection, recommendation, or scheduling by the first communication device for the second communication device). For example, the higher the service latency requirement, the higher the priority or lower the weight of resource selection, recommendation, or scheduling by the first communication device for the second communication device, or vice versa.

[0056] (c) Service data volume. For example, the service data volume of the services that the second communication device needs to transmit can be sorted in ascending or descending order. Based on the sorting result, a first target value for the second communication device (i.e., the order, priority, or weight of resource selection, recommendation, or scheduling by the first communication device for the second communication device) can be determined. For example, the larger the service data volume, the higher the priority or weight of resource selection, recommendation, or scheduling by the first communication device for the second communication device, or vice versa.

[0057] (d) Service reliability requirements. For example, the services that the second communication device needs to transmit can be sorted in ascending or descending order of reliability. Based on the sorting result, a first target value for the second communication device can be determined (i.e., the order, priority, or weight of resource selection, recommendation, or scheduling by the first communication device for the second communication device). For example, the higher the service reliability requirement, the higher the priority or weight of resource selection, recommendation, or scheduling by the first communication device for the second communication device, or vice versa.

[0058] (e) Service communication distance requirements. For example, the service communication distance requirements of the services that the second communication device needs to transmit can be sorted in ascending or descending order, and the first target value of the second communication device can be determined based on the sorting result (i.e., the order, priority, or weight of resource selection, resource recommendation, or resource scheduling by the first communication device for the second communication device). For example, the greater the service communication distance requirement, the higher the priority or weight of resource selection, resource recommendation, or resource scheduling by the first communication device for the second communication device, or vice versa.

[0059] Optionally, the QoS parameters can be carried in the first information, and other QoS parameters, such as the service rate, can also be included.

[0060] (2) The number of times the first communication device performs resource selection, resource scheduling, or resource recommendation for the second communication device within the first time period. For example, the second communication device can be sorted in ascending or descending order according to the number of times the first communication device performs resource selection, resource scheduling, or resource recommendation for the second communication device within the first time period to obtain the first target value of the second communication device. For example, the more times the first communication device performs resource selection, resource scheduling, or resource recommendation for the second communication device within the first time period, the higher the priority or the greater the weight of the second communication device, or vice versa. The first time period can be a historical period, and the time end can be the current moment or before the current moment; the first time period can also be from a moment before the current moment to a future point in time.

[0061] Optionally, the first time period may include M time units, where M is a rational number greater than zero. The time unit can be the length of a resource selection window, for example, the length of 32 time slots. The first time period can be n resource selection windows, or 1 / n of a resource selection window, where n is a rational number greater than zero.

[0062] (3) The total number of resources that the first communication device selects, schedules, or recommends for the second communication device during the second time period. For example, the first target value of the second communication device is obtained by sorting the total number of resources of the second communication device in ascending or descending order. For example, the more total resources that the first communication device selects, schedules, or recommends for the second communication device during the second time period, the higher the priority of the second communication device or the lower its weight, or vice versa. The second time period can be a historical period, and the time limit can be the current moment or a time before the current moment; the second time period can also be from a moment before the current moment to a future point in time.

[0063] The total number of resources can be the sum of resources that are beneficial for the second communication device to use for service transmission, the sum of resources that are not beneficial for the second communication device to use for service transmission, or the sum of the total number of resources recommended for the second communication device to use and the total number of resources not recommended for the second communication device to use.

[0064] Optionally, the second time period may include T time units, where T is a rational number greater than zero. The time unit can be the length of a resource selection window, for example, the length of 32 time slots. The second time period can be m resource selection windows, or 1 / m of a resource selection window, where m is a rational number greater than zero.

[0065] (4) The distance between the second communication device and the first communication device. For example, the second communication device is sorted in ascending or descending order according to the distance between the second communication device and the first communication device to obtain the first target value of the second communication device. For example, the greater the distance between the second communication device and the first communication device, the higher the priority or the greater the weight of the second communication device, or vice versa.

[0066] The distance between the second communication device and the first communication device can be determined by the difference between the zone IDs of the second and first communication devices, or by the number of zones from the zone where the second communication device is located to the zone where the first communication device is located (optionally, at the dimension or progress level, it can be determined by the number of zones from the zone where the second communication device is located to the zone where the first communication device is located), or by the reference signal received power (RSRP) of the first communication device receiving the second communication device.

[0067] (5) The time of receiving the first information. For example, sort the first information in ascending or descending order according to the time of receipt to obtain the first target value of the second communication device. For example, the earlier the first information is received, the higher the priority or the greater the weight of the corresponding second communication device, or vice versa.

[0068] (6) The communication type of the service that the second communication device needs to transmit. For example, if the communication type of the service that the second communication device needs to transmit includes broadcast, multicast and unicast, optionally, unicast has the highest priority or the heaviest weight, multicast has the next highest priority or weight, and broadcast has the lowest priority or the heaviest weight.

[0069] Optionally, the communication type of the service that the second communication device needs to transmit can be carried in the first information.

[0070] (7) The transmission time of the service that the second communication device needs to transmit. The transmission time can be the latest transmission time or the earliest transmission time. For example, the closer the latest transmission time of the service to be transmitted is to the current time, the higher the ranking, priority or weight of the second communication device; or, the closer the latest transmission time of the service to be transmitted is to the current time, the higher the priority of the second communication device; or the closer the latest transmission time of the service to be transmitted is to the current time, the greater the weight of the second communication device.

[0071] Optionally, the latest transmission time of the service that the second communication device needs to transmit can be carried in the first information.

[0072] (8) The transmission time that the first communication device needs to transmit the second information. The transmission time can be the latest transmission time or the earliest transmission time. For example, the second communication device whose latest transmission time of the second information to be transmitted is closer to the current time is ranked higher, or the second communication device whose latest transmission time of the second information to be transmitted is closer to the current time has a higher priority, or the second communication device whose latest transmission time of the second information to be transmitted is closer to the current time has a greater weight.

[0073] In this embodiment of the application, the second information can be the feedback signaling of the first information.

[0074] Optionally, the latest transmission time for the first communication device to transmit the second information can be carried in the first information.

[0075] (9) The target information of the second information. Optionally, the target information of the second information includes, but is not limited to, at least one of the following (a) to (d):

[0076] (a) The number of resources used to transmit the second information; for example, the resources used to transmit the second information can be sorted in ascending or descending order to obtain a first target value for the second communication device. For example, the more resources used to transmit the second information, the higher the priority of the second communication device, or vice versa. Alternatively, the more resources used to transmit the second information, the greater the weight of the second communication device, or vice versa.

[0077] (b) The size of the resources used to transmit the second information; for example, the resources used to transmit the second information can be sorted in ascending or descending order to obtain a first target value for the second communication device. For example, the larger the resource size used to transmit the second information, the higher the priority of the second communication device, or vice versa. Alternatively, the larger the resource size used to transmit the second information, the greater the weight of the second communication device, or vice versa.

[0078] (c) The maximum or minimum number of resources available for transmitting the second information; for example, the second communication devices can be sorted in ascending or descending order according to the maximum or minimum number of resources available for transmitting the second information to obtain a first target value. For example, the larger the maximum number of resources available for transmitting the second information, the higher the priority of the second communication device, or vice versa. Alternatively, the more maximum resources available for transmitting the second information, the greater the weight of the second communication device, or vice versa. Alternatively, the smaller the minimum number of resources available for transmitting the second information, the higher the priority of the second communication device, or vice versa. Alternatively, the smaller the minimum number of resources available for transmitting the second information, the greater the weight of the second communication device, or vice versa.

[0079] (d) The earliest or latest time of the resources available for transmitting the second information. For example, the resources available for transmitting the second information can be sorted in ascending or descending order to obtain the first target value of the second communication device. For example, the later the earliest time of the resources available for transmitting the second information, the higher the priority of the second communication device, or vice versa. Alternatively, the later the earliest time of the resources available for transmitting the second information, the greater the weight of the second communication device, or vice versa. Alternatively, the earlier the latest time of the resources available for transmitting the second information, the higher the priority of the second communication device, or vice versa. Alternatively, the earlier the latest time of the resources available for transmitting the second information, the greater the weight of the second communication device, or vice versa.

[0080] (10) The type of the second communication device. For example, a power-limited UE (or energy-saving UE) or a randomly selected UE, or a header UE or a relay UE with priority, i.e., higher priority or greater weight, or a higher position in the order.

[0081] Optionally, the type of the second communication device may be carried in the first information.

[0082] (11) The type of the target receiver corresponding to the second communication device. For example, if the second communication device requests resource recommendations from the first communication device to transmit data to the third communication device, then the third communication device is the target receiver corresponding to the second communication device. For example, if the target receiver is a power-limited UE (or energy-saving UE), a randomly selected UE, a header UE, or a relay UE, then the second communication device is ranked higher, or has a higher priority, or has a heavier weight.

[0083] (12) The distance between the second communication devices.

[0084] S214, based on the first target value, perform resource selection for the at least one second communication device, or perform resource scheduling for the at least one second communication device, or perform resource recommendation for the at least one second communication device.

[0085] In this application, a first communication device selects resources, schedules resources, or recommends resources for at least one second communication device based on a first target value. For example, by determining the order, priority, or weight value for resource selection, scheduling, or recommendation for at least one second communication device according to the first target value, the first communication device can ensure the accuracy and timeliness of higher-priority service transmissions while reducing the probability of service timeouts, thus effectively improving the system's transmission performance.

[0086] In one possible implementation, prior to S214, the first communication device obtains a first target parameter through control node configuration, protocol definition, relay node forwarding, or resource coordination or scheduling terminal notification. The first target parameter includes at least one of the following: the start time of the first time period or the configuration rule of the first time period, the start time of the second time period or the configuration rule of the first time period, the first parameter, an indication of whether to determine the first target value based on the first parameter, an indication of whether to perform resource selection, resource scheduling, or resource recommendation based on the first target value, the scope of use for resource selection, resource scheduling, or resource recommendation based on the first target value, and the content of use for resource selection, resource scheduling, or resource recommendation based on the first target value.

[0087] Optionally, the first target parameter is configured or notified through one of the following: Sidelink Control Information (SCI), Downlink Control Information (DCI), Radio Resource Control (RRC) signaling, Medium Access Control (MAC) Control Element (CE), or Sidelink Feedback Control Information (SFCI).

[0088] In this embodiment, the first communication device selects resources for the second communication device, schedules resources for the second communication device, or recommends resources for the second communication device based on the first target value, thereby obtaining second information. In one possible implementation, the second information may include at least one of the following:

[0089] (1) Resource information that is beneficial for the data receiving end to receive, including time-frequency domain resources and / or resource periods.

[0090] (2) Resource information that is not conducive to data reception by the data receiving end, including time-frequency domain resources and / or resource periods.

[0091] (3) The validity period of the resources indicated in the recommendation information. Optionally, this may include the length of the validity period, the validity time point, the number of validity attempts, etc.

[0092] (4) Recommended communication types. Optionally, this may include broadcast services and / or multicast services and / or unicast services.

[0093] (5) The strength of the recommendation information, such as whether it is mandatory or optional.

[0094] In one possible implementation, the first communication device can determine the first target value of the second communication device corresponding to the first information received within the third time period, and select, schedule, or recommend resources for each second communication device in turn according to the first target value of each second communication device, and then send the second information to each second communication device.

[0095] Then, for the first target value of the second communication device corresponding to the first information received in the next third time period, resources are selected, scheduled, or recommended for each second communication device, and then the second information is sent to each second communication device, and so on.

[0096] Optionally, the third time period may include S time units, where S is a rational number greater than zero. The time unit can be the length of a resource selection window, for example, the length of 32 time slots. The third time period can be p resource selection windows, or 1 / p of a resource selection window, where p is a rational number greater than zero.

[0097] Alternatively, in another possible implementation, the first communication device may not perform resource selection, scheduling, or recommendation for the second communication device on a time interval basis (i.e., periodicity) or according to the terminal implementation (i.e., non-periodicity). In this case, the first communication device can maintain a pending queue, the order of which is determined based on the first target value of each second communication device. For example, the higher the first target value (as priority), the higher its position in the queue. Each time the first communication device receives a first piece of information, it determines the position of the second communication device in the pending queue based on the first target value of the corresponding second communication device. When performing resource selection, scheduling, or recommendation, it performs the corresponding resource selection, scheduling, or recommendation for the second communication devices in the pending queue according to their order, and then sends the second piece of information.

[0098] In the above possible implementations, when multiple first messages are received at the same time, the order of the multiple second communication devices in the queue to be processed is determined according to the first target value of the second communication device corresponding to the multiple first messages.

[0099] In the above possible implementations, to avoid frequent changes in the position of the second communication devices in the processing queue, based on the first target value, if the priority of the second communication device corresponding to the currently received first information is determined to be greater than or equal to a first proportion of the second communication devices in the processing queue, then the second communication devices in the processing queue are reordered according to the first target value. Alternatively, the second communication device corresponding to the currently received first information is placed at position P in the processing queue, where P is less than Q, and Q is the total number of senders in the queue to be recommended. If the priority of the second communication device corresponding to the currently received first information is less than the first proportion of the second communication devices in the processing queue, then the second communication device corresponding to the currently received first information is placed at the tail of the processing queue.

[0100] In one possible implementation, after S214, the method may further include: sending the second information to the at least one second communication device, wherein the second information carries transmission resource information determined for the second communication device; or the second information carries resource information determined for the second communication device that is unfavorable to transmission; or the second information carries resource information determined for the second communication device that is favorable to transmission; or the second information carries resource information determined for the second communication device that is unusable for data transmission. The second communication device can determine the resource information used for data transmission through the second information.

[0101] In the above possible implementations, the second information also carries the identifier of the target receiving end of the service that the second communication device needs to transmit. This identifier can be the UE ID of the target receiving end, the group ID to which the target receiving end belongs (i.e., group ID), or the intra-group ID of the group to which the target receiving end belongs (i.e., M_ID). For example, in... Figure 4 In this scenario, TXUE 1 requests resources from Co-UE for communication with RX UE 2. Co-UE can determine a first target value for RX UE 2 and can send second information to RX UE 2, which may carry the identifier of RX UE 2. Through this possible implementation, the second communication device can determine the data transmission resources with the target receiving end.

[0102] In one possible implementation, before the first communication device sends the second information to the second communication device, if at least one of the following conditions is met, then the sending or transmission of the second information is abandoned, or resource selection, resource scheduling, or resource recommendation for the second communication device is abandoned:

[0103] (1) The transmission time of the second information exceeds the latency requirement of the service to be transmitted by the second communication device;

[0104] (2) The transmission time of the second information exceeds the latest transmission time of the service to be transmitted by the second communication device.

[0105] (3) The transmission time of the second information exceeds the latest transmission time of the second information.

[0106] The transmission time of the second information can be either the earliest or the latest transmission time. For example, the transmission time of the second information can be the time when the second information is sent from the first communication device or the time when the second information arrives at the second communication device. Specifically, it can be determined based on the latency requirements of the service to be transmitted, the latest transmission time of the service to be transmitted, and the latest transmission time of the second information.

[0107] For example, if the transmission time of the second information is the time when the second information arrives at the second communication device, the first communication device can determine the sending time of the second information before transmitting the second information, and then estimate the transmission time of the second information from the first communication device to the second communication device based on the relevant information of the second information and the network environment. Thus, it can estimate the time when the second information arrives at the second communication device, and thus determine whether the time exceeds the delay requirement, or the latest transmission time of the service to be transmitted, or the latest transmission time of the second information.

[0108] This possible implementation method can solve the collision problem that occurs when selecting recommended resources, further improve the feasibility of the solution, and enhance transmission performance and system performance.

[0109] In one possible implementation, when sending the second information to at least one second communication device, the information can also be sent according to the first target value. For example, the second information can be sent to the second communication device in ascending or descending order of the first target value.

[0110] Figure 5 This diagram illustrates a flowchart of an information transmission method according to an embodiment of this application. This method 400 can be executed by a first communication device. In other words, the method can be executed by software or hardware installed on the first communication device. Figure 5 As shown, the method may include the following steps.

[0111] S510, the first communication device receives at least one first message.

[0112] This step is the same as S210 in method 200, and you can refer to the description in method 200 for details.

[0113] S512, determine a second target value for at least one second communication device based on the first parameter, wherein the second communication device is the sender of the first information and / or the receiver of the second information.

[0114] The difference between this step and S412 in method 200 is that the second target value can be used to indicate the order in which the second information is sent to at least one second communication device. The second target value can directly indicate the order of the second information, or it can indicate the priority of sending the second information, or it can indicate the weight of sending the second information, etc. However, its determination method is the same as the first target value in method 200; please refer to the relevant description in method 200 for details. Everything else is the same as in method 200; please refer to the description in method 200 for details.

[0115] S514, based on the second target value, send second information to the at least one second communication device.

[0116] In this embodiment of the application, the second information is the same as the second information in method 200, and for details, please refer to the description in method 200.

[0117] In this embodiment of the application, the first communication device can send second information to the second communication device in the order indicated by the second target value.

[0118] In one possible implementation, prior to S514, the first communication device may select resources for the second communication device, schedule resources for the second communication device, or recommend resources for the second communication device in the manner described in method 200, to determine the second information. Alternatively, the first communication device may also select resources for the second communication device, schedule resources for the second communication device, or recommend resources for the second communication device in the order described in other methods to determine the second information; specific implementations in this application are not limited to these methods.

[0119] The information transmission method provided in this application embodiment allows a first communication device to determine a second target value for a second communication device based on a first parameter when it receives at least one first message. The second communication device is the sender of the first message and / or the receiver of the second message. Then, based on the second target value, the first communication device sends the second message to the second communication device. This allows the first communication device to determine, upon receiving at least one first message, to send corresponding resource selection, scheduling, or recommendation information to the second communication device in sequence. This ensures the accuracy and timeliness of higher-priority service transmissions, while also reducing the probability of service timeouts and effectively improving the system's transmission performance.

[0120] In one possible implementation, before the first communication device sends the second information to the second communication device, if at least one of the following conditions is met, then the sending or transmission of the second information is abandoned, or resource selection, resource scheduling, or resource recommendation for the second communication device is abandoned:

[0121] (1) The transmission time of the second information exceeds the latency requirement of the service to be transmitted by the second communication device;

[0122] (2) The transmission time of the second information exceeds the latest transmission time of the service to be transmitted by the second communication device.

[0123] (3) The transmission time of the second information exceeds the latest transmission time of the second information.

[0124] In the above possible implementations, the transmission time of the second information can be either the earliest transmission time or the latest transmission time. For example, the transmission time of the second information can be the time when the second information is sent from the first communication device or the time when the second information arrives at the second communication device. Specifically, it can be determined based on the latency requirements of the service to be transmitted, the latest transmission time of the service to be transmitted, and the latest transmission time of the second information.

[0125] For example, if the transmission time of the second information is the time when the second information arrives at the second communication device, the first communication device can determine the sending time of the second information before transmitting the second information, and then estimate the transmission time of the second information from the first communication device to the second communication device based on the relevant information of the second information and the network environment. Thus, it can estimate the time when the second information arrives at the second communication device, and thus determine whether the time exceeds the delay requirement, or the latest transmission time of the service to be transmitted, or the latest transmission time of the second information.

[0126] This possible implementation method can solve the collision problem that occurs when selecting recommended resources, further improve the feasibility of the solution, and enhance transmission performance and system performance.

[0128] Example 1

[0129] In this embodiment, the example of an RX UE or Co-UE recommending resources to a TX UE is used for illustration.

[0130] In this embodiment, when an RX UE or Co-UE receives N (N>=1) resource recommendation requests within a time period L0 or at time T0, the order of resource selection, recommendation information transmission, recommendation priority, or weight for different resource recommendation request senders (TX UEs) can be determined according to at least one of the following rules:

[0144] (8) Determining the latest transmission time of the recommended resource signaling fed back by the RX UE or Co-UE. Optionally, the closer the latest transmission time is to the current time, the higher the priority or weight, and the earlier it is ranked; in addition, the latest transmission time of the recommended resource signaling fed back by the RX UE or Co-UE can be carried by the TX UE in the recommended resource request signaling.

[0151] Optionally, if the RX UE or Co-UE sends recommendation information to certain TX UEs after the delay deadline for the data to be transmitted by the TX UE, or after the latest transmission time of the recommendation information, the RX UE or Co-UE will abandon the resource recommendation for that TX UE.

[0152] Optionally, the latest transmission time of the recommendation information and the delay deadline for the data to be transmitted can be notified by requesting the recommendation information.

[0153] Optionally, the TX UE's destination ID can be included in the recommendation information.

[0154] Example 2

[0155] In this embodiment, the example of an RX UE or Co-UE recommending resources to a TX UE is used for illustration.

[0156] The difference between this embodiment and Embodiment 1 is that L0 is not configured, i.e., L0 is infinite.

[0157] In this embodiment, when the RX UE or Co-UE successively receives resource recommendation requests, the order of recommended resource selection, the order of recommendation information transmission, or the priority or weight of different resource recommendation request senders (TX UEs) is determined according to at least one of the following rules:

[0158] (1) Sort according to the receiving time of different request information, first come first served (i.e., the higher the priority or weight);

[0159] Requests received at the same time can be sorted based on factors such as the QoS parameters mentioned in Example 1, the number and frequency of recommended resources over a period of time, and the distance between TX UEs and RX UEs or Co-UEs. Alternatively, requests received at the same time can be sorted randomly.

[0160] (2) Maintain a sorted, priority, or weighted queue, sorting different request information according to their priority (ascending or descending order). The RX UE or Co-UE selects resources and sends recommended resources according to the queue order. For newly received recommendation requests, a preemption mechanism will be triggered if certain conditions are met.

[0161] The sorting criteria are similar to those in Example 1:

[0163] (b) The number of times the RX UE or Co-UE recommends resources to the TX UE; or the total amount of resources recommended, optionally, resources that are favorable to reception and resources that are unfavorable to reception are counted separately.

[0164] (c) The distance between the RX UE or Co-UE and the TX UE.

[0165] (d) Other factors in Example 1.

[0166] The preemption mechanism can be triggered by one of the following conditions:

[0167] (a) If the TX UE corresponding to the newly received recommended resource request has a QoS parameter for the data to be transmitted (including but not limited to: priority, amount of data to be transmitted, latency requirement, reliability requirement, communication distance requirement) higher than the minimum value in the queue; or higher than x% in the queue, then the preemption mechanism is triggered.

[0168] (b) If the number of times or the total amount of resources recommended to the TX UE by the TX UE, RX UE or Co-UE corresponding to the newly received recommended resource request is higher than the minimum value in the queue; or higher than x% in the queue, then the preemption mechanism is triggered.

[0169] (c) If the distance between the TX UE corresponding to the newly received recommended resource request and the RX UE or Co-UE to the TX UE is less than or equal to the minimum value in the queue or greater than or equal to the maximum value in the queue; or less than or equal to x% in the queue, or greater than or equal to y% in the queue, then the preemption mechanism is triggered.

[0170] The preemption mechanism is triggered only if the above conditions are met; otherwise, the item is placed at the end of the queue.

[0171] The preemption mechanism is one of the following:

[0172] (a) The queue is reordered, and the recommended order corresponding to the TX UE is reordered according to the sorting criteria.

[0173] (b) The recommended order for this TX UE is the Nth position in the sequence, or, in special cases, the first position.

[0174] In the above embodiments one and two, the resource recommendation request information carries at least one of the following:

[0178] 3. The latest time or time period for sending the recommendation information.

[0179] 4. Maximum number of times recommendation information can be sent.

[0180] 5. The nature of the recommendation information, for example, whether the recommendation information carries resource information that is beneficial to the receiver's data reception, or resources that are detrimental to the receiver's data reception.

[0181] 6. The location of the transmission resources for the recommendation information, including time-domain resources and / or frequency-domain resources.

[0182] 7. Recommended resource request signaling identifier, optional, can be understood as the resource request signaling of R17.

[0183] The content of the resource recommendation information may include at least one of the following:

[0184] 1. Resource information that is beneficial for the data receiving end to receive, including time-frequency domain resources and / or resource periods.

[0185] 2. Resource information that is not conducive to data reception by the data receiver, including time-frequency domain resources and / or resource periods.

[0186] 3. The validity period of the resources indicated in the recommendation information. Optional features include the length of the validity period, the valid time point, and the number of valid uses.

[0187] 4. Recommended applicable communication types. Optional: broadcast services and / or multicast services and / or unicast services.

[0188] 5. The strength of the recommendation information, such as whether it must be applied or can be used optionally.

[0189] The recommended resource can be one of the following selected by the RX UE or Co-UE based on the service characteristics of the received TX UE:

[0190] 1. Resources that facilitate data reception for the RX UE corresponding to the TX UE.

[0191] 2. Resources that are detrimental to the data reception of the RX UE corresponding to the TX UE, such as resources with excessive interference.

[0192] 3. Resources that the data receiving end corresponding to the TX UE is in the sending state for a long time.
