[0165] FIG1A is a schematic diagram of a method for determining resources according to an embodiment of the present disclosure. As shown in FIG1A , a communication system 100 includes a terminal 101 and a terminal 102 .

It is understandable that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. A person skilled in the art will know that with the evolution of the system architecture,

[0167] With the emergence of new business scenarios, the technical solutions proposed in the embodiments of the present disclosure are also applicable to similar technical problems. The following embodiments of the present disclosure can be applied to the communication system 100 shown in Figure 1A, or part of the subject, but are not limited thereto. The subjects shown in Figure 1A are examples. The communication system may include all or part of the subjects in Figure 1A, or may include other subjects other than Figure 1A. The number and form of each subject are arbitrary. The connection relationship between the subjects is an example. The subjects may be connected or disconnected. The connection may be in any manner, which may be a direct connection or an indirect connection, and may be a wired connection or a wireless connection.

[0168] The embodiments of the present disclosure may be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G New Radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future Generation Radio Access (FX), Global System for Mobile Communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.17 (WiMAX (registered trademark)), IEEE 802.18 (WiMAX (registered trademark)), IEEE 802.19 (WiMAX (registered trademark)), IEEE 802.20 (WiMAX (registered trademark)), IEEE 802.21 (WiMAX (registered trademark)), IEEE 802.22 (WiMAX (registered trademark)), IEEE 802.23 (WiMAX (registered trademark)), IEEE 802.24 (WiMAX (registered trademark)), IEEE 802.25 (WiMAX (registered trademark)), IEEE 802.26 (WiMAX (registered trademark)), IEEE 802.27 (WiMAX (registered trademark)), IEEE 802.28 (WiMAX (registered trademark)), IEEE 802.29 (WiMAX (registered trademark)), IEEE 802.30 (WiMAX (registered trademark)), IEEE 802.31 (WiMAX (registered trademark)), IEEE 802.32 (WiMAX (registered trademark)), IEEE 802.33 (WiMAX (registered trademark)), 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other resource determination methods, and next-generation systems based on and extending these systems. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0169] The disclosed embodiments can be applied to LTE sidelink carrier aggregation (SL CA). If the Physical Sidelink Control Channel (PSCCH) / Physical Sidelink Control Channel (PSSCH) transmissions of multiple carriers overlap in the time domain, and the total power transmitted by multiple carriers on the sidelink exceeds Pcmax, the transmit power of the carrier with the highest priority value will be reduced or discarded, and this process will be repeated on the remaining carriers until the total transmit power does not exceed Pcmax. Pcmax refers to the maximum transmit power of the UE.

[0170] The embodiments of the present disclosure can be applied to NR SL CA. The transmission of multiple carriers may overlap in the time domain, but in this case, the SCS of the BWP corresponding to the resource pool used for transmission in the multiple carriers may be different, which can be understood as carrier aggregation supporting different SCSs in R19.

[0171] In some embodiments, all resources within the time window corresponding to the current resource selection are candidate resources, and resources obtained by the resource selection before the current resource selection are selected resources. The candidate resources and the selected resources may overlap in the time domain.

[0172] Figure 1B is a schematic diagram illustrating SL-CA transmission on carriers with different SCSs according to an embodiment of the present disclosure. As shown in Figure 1B , the transmissions of carriers 0 and 1 overlap in the time domain. The SCS of carrier 0 is 15 kHz, with candidate resource #1 in slot #0. The SCS of carrier 1 is 30 kHz, with selected resource #2 in slot #0. The terminal performs SL-CA transmission on carriers 0 and 1.

[0173] In some embodiments, if the SL-CA transmission of the candidate resources and the selected resources overlapping in the time domain exceeds the capability limit of the terminal, the candidate resources will be excluded, so that the candidate resources exceeding the capability limit of the terminal cannot be transmitted through SL-CA.

[0174] Figure 1C is a second schematic diagram of SL-CS transmission of carriers with different SCSs according to an embodiment of the present disclosure. As shown in Figure 1C, the terminal has two carriers that need to be transmitted on the side link, namely carrier 0 and carrier 1, wherein the SCS of carrier 0 is 15kHz, and there is candidate resource #1 on slot #0; the subcarrier spacing of carrier 1 is 30kHz, and there is selected resource #2 on slot #0. The candidate resource on carrier #0 has a higher priority than the selected resource #2 on carrier #1, and slot #1 on carrier #1 is not occupied at this time, but because the SL-CA transmission of candidate resource #1 and selected resource #2 exceeds the terminal's capacity limit, candidate resource #1 is excluded and cannot be transmitted on the side link.

[0175] Figure 1D is a third schematic diagram of SL-CA transmission on carriers of different SCSs according to an embodiment of the present disclosure. As shown in Figure 1C, the terminal has three carriers for SL-CA transmission, namely carrier 0, carrier 1, and carrier 2. The subcarrier spacing of carrier 0 is 15kHz, and there is resource #1 on carrier 0; the subcarrier spacing of carrier 1 is 30kHz, and there are resources #2 and #3 on carrier 1; the subcarrier spacing of carrier 2 is 30kHz, and there are resources #4 and #5 on carrier 2; resources #1, #2, and #3 are selected resources, and resources #4 and #5 are candidate resources. The resources on carriers 0, 1, and 2 overlap in the time domain, and performing SL-CA transmission simultaneously exceeds the terminal's capability limit; at this time, candidate resources #4 and #5 on carrier #2 will be excluded and cannot perform SL-CA transmission.

[0176] In related technologies, the way in which a UE selects transmission resources on a carrier on a SL is not reasonable.

[0177] FIG2 is an interactive diagram of a resource determination method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a resource determination method for a communication system 100, the method comprising:

[0178] In step S2101 , the terminal 101 determines candidate resources and selected resources corresponding to the candidate resources.

[0179] In some embodiments, the terminal 101 determines candidate resources, where the candidate resources are resources within a time window corresponding to the moment of currently triggering resource selection.

[0180] In some embodiments, the terminal 101 determines each selected resource, where the selected resource is a resource obtained by a resource selection triggered before the current resource selection is triggered.

[0181] In some embodiments, the selected resource corresponding to the candidate resource is a selected resource that has a time domain overlap with the candidate resource.

[0182] Optionally, the capability of the terminal 101 includes at least one of the following: the radio frequency capability of the terminal 101, the number of supported carriers, the supported carrier combinations, and the supported maximum transmit power.

[0183] Step S2102: Terminal 101 determines a first candidate resource.

[0184] In some embodiments, a first candidate resource is determined from various candidate resources, where the first candidate resource is a candidate resource that satisfies a first condition among various candidate resources.

[0185] In some embodiments, the first condition includes: the priority value of the candidate resource is not greater than the first threshold; the priority value of the candidate resource is less than the priority value of the selected resource corresponding to the candidate resource; the subcarrier interval of the candidate resource is not greater than the second threshold; the starting time of the selection window corresponding to the candidate resource and the sending time of the selected resource corresponding to the candidate resource are not less than the first duration.

[0186] In some embodiments, the first condition further includes at least one of the following: the candidate resource does not have a corresponding selected resource; and the use of the candidate resource and the corresponding selected resource for SL-CA transmission does not exceed the capability limit of the terminal.

[0187] Optionally, the first threshold, the second threshold and the first duration are preset.

[0188] Step S2103: Terminal 101 determines the first selected resource.

[0189] In some embodiments, the terminal 101 determines selected resources corresponding to one or more candidate resources in the first candidate resources as first selected resources, and the first selected resources include selected resources that meet the second condition.

[0190] In some embodiments, the terminal 101 obtains a first indication, where the first indication is used to indicate one or more selected resources.

[0191] In some embodiments, the terminal 101 determines that the selected resource corresponding to the first candidate resource is in the first indication, and determines the selected resource that meets the second condition among the selected resources corresponding to the first candidate resource as the first selected resource.

[0192] In some embodiments, the second condition includes: the candidate resource corresponding to the selected resource is a candidate resource in the first candidate resources, and SL-CA transmission of the selected resource and the corresponding candidate resource exceeds the capability limit of the terminal.

[0193] In some embodiments, the second condition includes at least one of the following: the order of the selected resources in the first sorting is not greater than the first order, and the first sorting is a descending order of the priority values ​​of all selected resources corresponding to the candidate resources; the order of the selected resources in the second sorting is not greater than the second order, and the second order is a descending order of the subcarrier spacing of all selected resources corresponding to the candidate resources.

[0194] In some embodiments, performing SL-CA transmission on the selected resources and the corresponding candidate resources that are greater than the first order in the first ranking exceeds the capability limit of the terminal.

[0195] In some embodiments, performing SL-CA transmission on the selected resources and the corresponding candidate resources that are greater than the second order in the second ranking exceeds the capability limit of the terminal.

[0196] For example, the first candidate resource includes three candidate resources, namely candidate resources a~c, and the selected resources corresponding to candidate resource a include selected resources A~C. Candidate resource a and selected resources A~C overlap in the time domain, that is, the selected resources corresponding to candidate resource a are A~C; using candidate resource a and selected resources A~C for carrier transmission on the side link exceeds the capacity limit of terminal 101, while using candidate resource a and selected resources A and B for carrier transmission on the side link does not exceed the capacity limit of terminal 101, and using candidate resource a and selected resource C for SL-CA transmission does not exceed the capacity limit of terminal 101, then the selected resources A~C can be reselected according to the second condition to determine the selected resources that need to be excluded from A~C, and the selected resources A~C can be sorted according to the priority value, that is, The selected resource with the highest priority value is placed at the front, and the selected resource with the lowest priority value is placed at the back, and they are excluded in order of priority value. For example, the priority value of selected resource C is the highest, and the priority value of selected resource A is the lowest. In this case, selected resource C will be excluded in the first round. At this time, terminal 101 determines that the SL-CA sending of candidate resource a and the corresponding selected resources A and B does not exceed the capacity limit of terminal 101, and the resource reselection of selected resources A to C is completed. If the SL-CA sending of candidate resource a and the corresponding selected resources A and B exceeds the capacity limit of terminal 101, the selected resources A and B are reselected according to the above resource reselection method until the SL-CA sending of candidate resource a and the selected resources after resource reselection does not exceed the capacity limit of terminal 101.

[0197] For example, the first candidate resource includes three candidate resources, namely candidate resources a to c, the selected resources corresponding to candidate resource a include selected resources A to C, and candidate resource a and selected resources A to C overlap in the time domain, that is, the selected resources corresponding to candidate resource a are A to C; using candidate resource a and selected resources A to C to transmit on the side link carrier exceeds the capacity limit of terminal 101, while using candidate resource a and selected resources A and B to transmit on the side link carrier does not exceed the capacity limit of terminal 101, and using candidate resource a If the SL-CA transmission with the selected resource C does not exceed the capacity limit of the terminal 101, the selected resources A to C can be reselected according to the second condition to determine the selected resources that need to be excluded from A to C. The selected resources A to C can be sorted according to the subcarrier spacing, that is, the selected resources with the largest subcarrier spacing are at the front, and the selected resources with the smallest subcarrier spacing are at the back, and are excluded in descending order according to the subcarrier spacing. For example, the subcarrier spacing of the selected resource C is the largest, and the subcarrier spacing of the selected resource A is the smallest. In the first round, the selected resources A to C are sorted according to the subcarrier spacing. Source C is excluded. At this time, the terminal 101 determines that the SL-CA sending of the candidate resource a and the corresponding selected resources A and B does not exceed the capability limit of the terminal 101, and the resource reselection of the selected resources A to C is completed. If the SL-CA sending of the candidate resource a and the corresponding selected resources A and B exceeds the capability limit of the terminal 101, the selected resources A and B are reselected according to the above resource reselection method until the SL-CA sending of the candidate resource a and the selected resources after the resource reselection does not exceed the capability limit of the terminal 101.

[0198] In some embodiments, resource reselection may be performed on the selected resources based on a combination of the priority value and the subcarrier spacing of the selected resources.

[0199] In step S2104 , the terminal 101 determines the second selected resource.

[0200] In some embodiments, a second selected resource is determined from the selected resources, and the second selected resource is a selected resource other than the first selected resource from the selected resources.

[0201] Step S2105: Terminal 101 uses the first candidate resource and the second selected resource to perform SL-CA transmission.

[0202] In some embodiments, the terminal 101 uses the first candidate resource and the second selected resource to perform SL-CA transmission.

[0203] Optionally, the first candidate resource and the second selected resource may send a signal for SL-CA, and the embodiment of the present disclosure does not limit the type and content of the signal.

[0204] In step S2106, terminal 102 receives a signal sent by terminal 101 via SL-CA.

[0205] In some embodiments, terminal 102 receives a signal sent by terminal 101 through SL-CA.

If the carrier transmission of candidate resource a and selected resources A to C on the side link exceeds the capacity limit of terminal 101, the first indication includes selected resources A to C.

[0337] Figure 6A is a fourth schematic diagram illustrating SL-CA transmission on carriers with different SCSs according to an embodiment of the present disclosure. As shown in Figure 6A , a terminal needs to transmit on two carriers on the sidelink: carrier 0 and carrier 1. Carrier 0 has an SCS of 15 kHz, and slot 0 contains candidate resource #1. Carrier 1 has a subcarrier spacing of 30 kHz, and slot 0 contains selected resource #2. At this point, SL-CA transmission of candidate resource #1 and selected resource #2 exceeds the terminal's capability limit.

[0338] According to the technical solution in the embodiment of the present disclosure, candidate resource #1 is a selected resource that meets the first condition. As the first candidate resource, according to the technical solution in the embodiment of the present disclosure, resource reselection is performed on the selected resource corresponding to candidate resource #1, and the reselection is performed according to the priority value and / or subcarrier spacing of the selected resource. Selected resource #2 is excluded, thereby ensuring that candidate resource #1 can be sent on the side link.

[0339] Figure 6B is a fifth schematic diagram illustrating SL-CA transmission on carriers with different SCSs according to an embodiment of the present disclosure. As shown in Figure 6B , a terminal performs SL-CA transmission on three carriers: carrier 0, carrier 1, and carrier 2. Carrier 0 has a subcarrier spacing of 15 kHz and hosts resource #1; carrier 1 has a subcarrier spacing of 30 kHz and hosts resources #2 and #3; carrier 2 has a subcarrier spacing of 30 kHz and hosts resources #4 and #5; resources #1, #2, and #3 are selected resources, while resources #4 and #5 are candidate resources; the resources on carriers 0, 1, and 2 overlap in the time domain, and performing SL-CA transmission simultaneously exceeds the terminal's capability limit.

[0340] According to the technical solution in the embodiment of the present disclosure, candidate resources #4 and #5 are selected resources that meet the first condition. As the first candidate resource, candidate resource #4 corresponds to selected resources #1 and #2, and candidate resource #5 corresponds to selected resources #1 and #3. Resource reselection is performed for the selected resources corresponding to candidate resources #4 and #5, respectively. For example: Among selected resources #1 and #2, selected resource #1 has the highest priority value, so selected resource #1 is excluded. At this time, SL-CA transmission of candidate resource #4 and selected resource #2 does not exceed the terminal's capability limit, and resource reselection for the selected resource corresponding to candidate resource #4 is completed. Among selected resources #1 and #3, selected resource #1 has the highest priority value, so selected resource #1 is excluded. At this time, SL-CA transmission of candidate resource #5 and selected resource #3 does not exceed the terminal's capability limit, and resource reselection for the selected resource corresponding to candidate resource #5 is completed.
