[0028] The resource selection method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0029] Figure 3 This document illustrates a flowchart of a resource selection method according to an embodiment of this application, as shown below. Figure 3 As shown, the method 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. The first communication device can be a terminal or a control node. The method may include the following steps.

[0030] Step S301: The first communication device determines whether to perform resource selection based on one or more of the at least one first information, according to the feature information of the received at least one first information; wherein the first information indicates the resource used for resource selection.

[0031] Optionally, at least one piece of first information is received within a certain time period, which may be a time period before the current time, or a time period ending at the current time, or a time period beginning before the current time and ending at a future time.

[0032] It should be understood that when the first communication device receives the first information, it can further analyze the characteristic information of each piece of the first information. The characteristic information can be carried by the first information or obtained through other means, such as protocol predefinition, network-side configuration, higher-layer configuration, relay node forwarding, notification from other terminals, or other measurement methods. Specifically, the first information may include: information related to the first information, information related to the second communication device that sends the first information, information related to the first communication device that receives the first information, and may also include transmission characteristics when sending or receiving the first information. In one embodiment, the characteristic information of the first information includes at least one of the following:

[0033] The time when the first communication device receives the first information;

[0034] The distance between the first communication device and the second communication device;

[0035] User equipment identifier of the first communication device;

[0036] User ID of the second communication device;

[0037] The group ID of the user group to which the second communication device belongs;

[0038] The group identifier of the user group to which the first communication device belongs;

[0039] The user identifier within the user group where the second communication device is located;

[0040] The user identifier within the user group to which the first communication device belongs;

[0041] The transmission method of the first information; wherein, the transmission method includes unicast, multicast and broadcast;

[0042] Whether a Radio Resource Control (RRC) connection is established between the first communication device and the second communication device;

[0043] The number of times the second communication device sends the first information during the second time period;

[0044] The amount of resources indicated in the first message sent by the second communication device during the third time period;

[0045] The second communication equipment has the following characteristics: it is a head node, a scheduling user, a scheduling node, a relay node, an auxiliary node, an energy-saving device, or a high-power device.

[0046] The second communication device is the sender of the first information.

[0047] The content of the first information may also include at least one of the following:

[0048] 1. Resource information that facilitates data reception at the data receiving end, including time-frequency domain resources and / or resource periods;

[0049] 2. Resource information that is detrimental to data reception at the receiving end, including time-frequency domain resources and / or resource periods;

[0050] 3. The validity period of resources indicated in the recommendation information may include the length of the validity period, the valid time point, the number of valid times, etc.;

[0051] 4. The recommended communication types may include broadcast services and / or multicast services and / or unicast services, etc.

[0052] 5. The strength of the recommendation information, such as whether it must be used, can be used, or cannot be used.

[0053] If the first communication device determines that the feature information of the first information meets the priority condition, it selects resources based on the resources indicated in the first information, including the resource information as described above, and then transmits data according to the resource selection result. If the feature information of the first information does not meet the priority condition, it does not select resources based on the resources indicated in the first information. The priority condition may be preset by the protocol, preset by the network, configured by the network, or notified by other communication devices.

[0054] Therefore, this application provides a resource selection method that determines whether to select resources based on one or more of the first information received, by using the feature information of at least one first information received, thereby enabling the optimal resource information to be used for resource selection and effectively improving transmission performance.

[0055] Figure 4 This document illustrates a flowchart of another resource selection method according to an embodiment of this application, as shown below. Figure 4As shown, the method 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. The method may include the following steps.

[0056] Step S401: Obtain a first information set, wherein the first information set includes the first information received within a first time period.

[0057] It should be understood that, optionally, a time period T0 can be configured first, and the duration of the first time period can be one T0 or N T0s; alternatively, the duration of the first time period can be configured directly. The first time period can also be configured to be infinite. All first information received within the first time period will be recorded in the first information set.

[0058] Step S402: Determine a second information set from the first information set based on the feature information of each first information set, and select resources based on the first information in the second information set;

[0059] The first information set includes the second information set.

[0060] In one implementation, the second information set is the first information set, meaning that all the first information received within the first time period is used for resource selection.

[0061] In another implementation, based on the characteristic information of each piece of first information, a portion of the first information in the first information set is determined to be included in the second information set, and resource selection is performed based on the second information set.

[0062] The feature information of the first information includes at least one of the following:

[0063] The time when the first communication device receives the first information;

[0064] The distance between the first communication device and the second communication device;

[0065] User equipment identifier of the first communication device;

[0066] User equipment identifier of the second communication device;

[0067] The group identifier of the user group to which the second communication device belongs;

[0068] The group identifier of the user group to which the first communication device belongs;

[0069] The user identifier within the user group where the second communication device is located;

[0070] The user identifier within the user group to which the first communication device belongs;

[0071] The transmission method of the first information; wherein, the transmission method includes unicast, multicast and broadcast;

[0072] Whether a wireless resource control connection is established between the first communication device and the second communication device;

[0073] The number of times the second communication device sends the first information during the second time period;

[0074] The amount of resources indicated in the first message sent by the second communication device during the third time period;

[0075] The second communication equipment has the following characteristics: it is a head node, a scheduling user, a scheduling node, a relay node, an auxiliary node, an energy-saving device, or a high-power device.

[0076] The second communication device is the sender of the first information.

[0077] The methods for determining whether to include a portion of the first information in the second information set may include at least one of the following:

[0078] In one implementation, a portion of the first information is determined based on the time t1 at which the first communication device receives the first information. A specific example is as follows:

[0079] The first information of time t1 in the second time period L is incorporated into the second information set. The second time period is within the first time period.

[0080] The first M messages received in the first information set can be included in the second information set according to the order of their arrival time t1.

[0081] The time period for receiving the first information is pre-divided and assigned different priorities. The priority of the first information is determined based on the time period in which it is received (t1), with earlier t1 indicating higher or lower priority. First information with a priority higher than a certain threshold is included in the second information set. For example, ... Figure 5 As shown, at the current time t0, the time period is divided into L3, L2, and L1. The priorities of the first messages a3, a2, and a1 received in each time period are P3, P2, and P1, respectively, where P1 > P2 > P3. This ensures that the most recently received first message has a higher priority. Because the first message has a time-sensitive nature, if it has not been processed for a long time, the resource indication information carried in the first message will also have its effectiveness reduced due to changes in system interference.

[0082] In another embodiment, the distance between the first communication device and the second communication device is determined by a portion of the first information. This distance can be either geographical or radio distance. It should be understood that the distance between the first and second communication devices can be determined based on their respective Zone IDs or Reference Signal Received Power (RSRP). Accordingly, determining the inclusion of this portion of the first information into the second information set may specifically include satisfying at least one of the following: the RSRP is greater than a preset first threshold; the difference between the Zone IDs of the two devices is less than a second threshold; and the difference in a certain dimension of the Zones where the two devices are located, such as latitude or longitude, is less than N Zones. The Zone ID can be carried by the first information or obtained through the location of the first and second communication devices.

[0083] In another implementation, some of the first information is determined based on the group identifier of the user group to which the second communication device and / or the first communication device belong. For example, first information in which the group identifiers of the second communication device and the first communication device are the same, differ by a fixed value, or have a difference within a certain range is included in the second information set.

[0084] In another implementation, a portion of the first information is determined based on the transmission method of the first information. Specific examples are as follows:

[0085] When the first information is transmitted via unicast, the corresponding first information is included in the second information set;

[0086] When the first information is transmitted via multicast, the corresponding first information is included in the second information set;

[0087] When the first information is transmitted via broadcast, the corresponding first information is included in the second information set.

[0088] In another implementation, some first information is determined based on whether a connection is established between the first communication device and the second communication device. This connection can be an RRC connection or a NAS connection. For example, the first communication device and the second communication device can perform unicast transmission based on an RRC connection, or multicast transmission based on an established RRC connection.

[0089] In another implementation, a portion of the first information is determined based on the number of first messages sent by the second communication device within the second time period T1. For example, if the number of first messages received from the same second communication device within the second time period T1 exceeds a third threshold, the corresponding first messages are included in the second information set. The length of the second time period T1 can be N time periods T0 or a separately defined length.

[0090] In another implementation, a portion of the first information is determined based on the number of resources indicated in the first information sent by the second communication device within the third time period T2. For example, if the number of resources indicated in the first information sent by the same second communication device within the third time period T2 exceeds a fourth threshold, the corresponding first information is included in the second information set. The length of the second time period T2 can be N time periods T0 or a separately defined length.

[0091] In another implementation, a portion of the first information is determined based on the device characteristics of the second communication device. For example, if the second communication device is at least one of a head node, a scheduling user, a scheduling node, a relay node, an auxiliary node, an energy-saving device, or a high-power device, the corresponding first information is incorporated into the second information set.

[0092] In another embodiment, a portion of the first information is determined based on the User ID of the second communication device. For example, when the first communication device receives the first information sent by the second communication device with the User ID of the target User ID, it includes the first information in the second information set. For example, the second communication device with the target User ID may be capable of sending and receiving unicast or broadcast data, or the second communication device with the target User ID may be a scheduling node, a relay node, a network-side device, a header user, or a scheduling user.

[0093] Therefore, this application provides a resource selection method, which obtains a first information set, the first information set including first information received within a first time period; determines a second information set from the first information set based on the feature information of each first information, and performs resource selection based on the first information in the second information set, thereby enabling the use of optimal resource information for resource selection and effectively improving transmission performance.

[0094] Figure 6 This document illustrates a flowchart of another resource selection method according to an embodiment of this application, as shown below. Figure 6 As shown, the method 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. The first communication device can be a terminal or a control node. The method may include the following steps.

[0095] Step S601: Determine the priority of the first information based on the feature information of the received first information.

[0096] The feature information of the first information includes at least one of the following:

[0097] The time when the first communication device receives the first information;

[0098] The distance between the first communication device and the second communication device;

[0099] User equipment identifier of the first communication device;

[0100] User equipment identifier of the second communication device;

[0101] The group identifier of the user group to which the second communication device belongs;

[0102] The group identifier of the user group to which the first communication device belongs;

[0103] The user identifier within the user group where the second communication device is located;

[0104] The user identifier within the user group to which the first communication device belongs;

[0105] The transmission method of the first information; wherein, the transmission method includes unicast, multicast and broadcast;

[0106] Whether a wireless resource control connection is established between the first communication device and the second communication device;

[0107] The number of times the second communication device sends the first information during the second time period;

[0108] The amount of resources indicated in the first message sent by the second communication device during the third time period;

[0109] The second communication equipment has the following characteristics: it is a head node, a scheduling user, a scheduling node, a relay node, an auxiliary node, an energy-saving device, or a high-power device.

[0110] The second communication device is the sender of the first information.

[0111] There are multiple ways to determine the priority; only a few implementation methods are given below.

[0112] In one implementation, the priority is determined based on the order in which the first communication device receives the first information; the earlier the information is received, the higher its priority. For example, the time of receiving the first information can be segmented into L1, L2, L3, etc., and a corresponding priority can be determined for each segment. First information received within the same time period has the same priority.

[0113] In another implementation, priority is determined based on the number of first messages transmitted by the second communication device during the fourth time period T3 and / or the number of resources indicated in the first messages. For example, a higher number of first messages received corresponds to a higher priority; or, a higher number of resources indicated in the received first messages corresponds to a higher priority.

[0114] In another implementation, priority is determined based on the distance between the first and second communication devices. Specifically, the distance can be determined based on RSRP or Zone ID calculations; the greater the distance, the lower the priority.

[0115] In another implementation, the priority is determined based on the nature of the second communication device. For example, if the second communication device is a scheduling UE or node, its corresponding priority is higher.

[0116] In another implementation, the priority is determined based on the transmission method of the first information. For example, when the first information is transmitted via unicast, the priority is the highest, followed by multicast transmission, and then broadcast transmission.

[0117] Step S602: Determine whether to select resources based on one or more of the first information according to the priority of the first information.

[0118] In one implementation, step S602 may include:

[0119] A third information set is determined based on the priority of the first information, and resource selection is performed based on the first information in the third information set; wherein the priority of the first information in the third information set is higher than the priority threshold.

[0120] It should be understood that the first piece of information included in the third information set can be either the first piece of information or the first piece of information in the second information set. First pieces of information with a priority higher than the priority threshold are selected from the first or second information sets and included in the third information set. Alternatively, after each first piece of information is received, the decision to include it in the third information set can be made directly based on the priority of that first piece of information.

[0121] In another implementation, if the first communication device has already selected resources based on the second information, step S602 may include:

[0122] If the priority of the first information is not lower than or higher than the priority of the second information, a resource reselection process is triggered; wherein, the second information is the first information received by the first communication device before the current moment.

[0123] When the first communication device has selected resources according to the second information with priority A and then receives the first information with priority B, when A > B or A ≥ B, the first communication device does not perform any operation; when A ≤ B or A < B, a resource reselection process is triggered.

[0124] Among them, the resource reselection process includes at least one of the following:

[0125] In the resource exclusion phase, exclude the resources indicated by both the first information and the second information;

[0126] In the resource exclusion phase, except for the first resource among the resources indicated by the first information and the second information, exclude the other resources indicated by the first information and the second information;

[0127] In the resource exclusion phase, exclude the resources indicated by the first information;

[0128] In the resource exclusion phase, except for the first resource among the resources indicated by the first information, exclude the other resources indicated by the first information;

[0129] After the candidate resource set is determined, merge the resources indicated by both the first information and the second information into the candidate resource set;

[0130] After the candidate resource set is determined, except for the first resource among the resources indicated by the first information and the second information, merge the other resources indicated by the first information and the second information into the candidate resource set;

[0131] After the candidate resource set is determined, merge the resources indicated by the first information into the candidate resource set;

[0132] After the candidate resource set is determined, except for the first resource among the resources indicated by the first information, merge the other resources indicated by the first information into the candidate resource set;

[0133] When determining the candidate resource set, merge the resources indicated by the first information and the second information into the candidate resource set;

[0134] When determining the candidate resource set, except for the first resource among the resources indicated by the first information and the second information, merge the other resources indicated by the first information and the second information into the candidate resource set;

[0135] When determining the candidate resource set, use the resources indicated by the first information as the candidate resource set;

[0136] When determining the candidate resource set, in addition to the first resource indicated by the first information, the other resources indicated by the first information are taken as the candidate resource set.

[0137] It should be understood that the values ​​of T, L, and M mentioned in the above embodiments, as well as the various threshold values ​​and thresholds, can be configured through the following methods:

[0138] The signaling can be notified by the control node or the scheduling node, and can be Downlink Control Information (DCI), Medium Access Control (MAC CE), Sidelink Control Information (SCI), or Sidelink Feedback Control Information (SFCI), etc.

[0139] Configuration is made by control nodes or network signaling messages, which can be RRC or PC5-RRC, etc.

[0140] Predefined by the protocol.

[0141] In addition, the transmission resources used for notification or configuration may be the Physical SideLink Shared Channel (PSSCH), Physical Downlink Control Channel (PDCCH), Physical SideLink Control Channel (PSCCH), Physical SideLink Feedback Channel (PSFCH), etc.

[0142] Therefore, this application provides a resource selection method, which obtains a first information set, the first information set including first information received within a first time period; determines a second information set from the first information set based on the feature information of each first information, and performs resource selection based on the first information in the second information set, thereby enabling the use of optimal resource information for resource selection and effectively improving transmission performance.

[0143] It should be noted that the resource selection method provided in this application embodiment can be executed by a resource selection device, or by a control module within the resource selection device for executing the resource selection method. This application embodiment uses the execution of the resource selection method by a resource selection device as an example to illustrate the resource selection device provided in this application embodiment.
