Description

Technical Field

[0001] This application belongs to the field of communication technology, and specifically relates to a method, apparatus, user equipment, and storage medium for synchronous resource configuration. Background Technology

[0002] In New Radio (NR) sidelink (SL) scenarios, when multiple component carriers (CCs) perform carrier aggregation (CA), the sub-carrier spacing (SCS) and transmission patterns of different CCs may differ. This can lead to misalignment of synchronization resources on each CC, resulting in high occupancy of synchronization signals in the time domain and reduced resource utilization. Furthermore, the misalignment of synchronization resources on each CC can also cause conflicts between the synchronization signal and other signals, thus affecting the reliability of sidelink services. Summary of the Invention

[0003] This application provides a method, apparatus, user equipment, and storage medium for configuring synchronous resources, which can solve the problem of misalignment of synchronous resources on multiple CCs, affecting the reliability of sidelink services.

[0005] Secondly, a synchronization resource configuration apparatus is provided, comprising: a determination module. The determination module is configured to determine target configuration parameters for the transmission of synchronization resources on at least two carriers. The target configuration parameters include at least one of the following: target time information and target interval information. The target time information indicates a target time, and the target interval information includes at least one of the following: a target time interval and a synchronization resource interval; wherein the target time at least includes the time for transmitting synchronization resources; and the configuration parameters of the synchronization resources on at least two carriers are at least partially identical.

[0006] Thirdly, a UE is provided, the UE including a processor, a memory, and a program or instructions stored in the memory and executable on the processor, wherein the program or instructions, when executed by the processor, implement the steps of the method described in the first aspect.

[0007] Fourthly, a UE is provided, including a processor and a communication interface, wherein the processor is configured to determine target configuration parameters for the transmission of synchronization resources on at least two carriers, the target configuration parameters including at least one of the following: target time information and target interval information, the target time information indicating a target time, the target interval information including at least one of the following: the interval of the target time and the interval of the synchronization resources; wherein the target time includes at least the time for transmitting the synchronization resources; and the configuration parameters of the synchronization resources on at least two carriers are at least partially the same.

[0008] Fifthly, a readable storage medium is provided, on which a program or instructions are stored, which, when executed by a processor, implement the steps of the method described in the first aspect.

[0009] In a sixth aspect, a chip is provided, the chip including a processor and a communication interface coupled to the processor, the processor being used to run programs or instructions to implement the method as described in the first aspect.

[0010] In a seventh aspect, a computer program / program product is provided, the computer program / program product being stored in a non-transient storage medium, the program / program product being executed by at least one processor to implement the steps of the synchronous resource configuration method as described in the first aspect.

[0028] The following explains some concepts and / or terms involved in the synchronization resource configuration method, apparatus, user equipment, and storage medium provided in the embodiments of this application.

[0029] 1. Carrier Aggregation (CA)

[0030] Carrier aggregation combines two or more carrier cells (CCs) to support a larger transmission bandwidth (e.g., up to 100MHz). Each carrier cell effectively corresponds to an independent cell, and is often equated with a single cell. The maximum bandwidth of each carrier cell is 20MHz. Carrier aggregation supports the aggregation of different carrier cells: carrier cells with the same or different bandwidths, adjacent or non-adjacent carrier cells within the same frequency band, and carrier cells within different frequency bands.

[0031] 2. Sidelink

[0032] It can also be called a secondary link, side link, or edge link, and is used for direct data transmission between UEs without going through network-side equipment.

[0033] The UE transmits Sidelink Control Information (SCI) via the Physical Sidelink Control Channel (PSCCH) and schedules the transmission of the Physical Sidelink Shared Channel (PSSCH) to send data. This transmission is broadcast, and the receiving end does not report whether the reception was successful to the sending end.

[0034] LTE sidelink supports two resource allocation modes: scheduled resource allocation and autonomous resource selection. In the former, the network-side equipment controls and allocates resources to each UE, while in the latter, the UE autonomously selects resources.

[0035] LTE supports sidelink carrier aggregation. The CA and Uu interfaces (i.e., downlink and uplink) of LTE sidelinks are different, and there is no distinction between primary component carrier (PCC) and secondary component carrier (SCC). In autonomous resource selection mode, the UE independently performs resource sensing and resource reservation on each CC.

[0036] The LTE sidelink is designed for specific public safety applications (such as emergency communications in disaster areas like fires or earthquakes) or vehicle-to-everything (V2X) communications. V2X communications include various services such as basic safety communications, advanced (autonomous) driving, platooning, and sensor extension. Because the LTE sidelink only supports broadcast communications, it is primarily used for basic safety communications; other advanced V2X services will be supported through the NR sidelink.

[0037] The 5G NR system can be used in operating frequency bands above 6GHz that are not supported by LTE, supporting greater operating bandwidth. The NR system also supports sidelink interface communication for direct communication between terminals.

[0038] Currently, sidelink transmission mainly consists of three transmission methods: unicast, multicast, and broadcast. Unicast is a one-to-one transmission, multicast is a one-to-many transmission, and broadcast is also a one-to-many transmission, but broadcast does not have the concept of UEs belonging to the same group.

[0039] On the sidelink, the PSCCH carries the SCI, which is used to schedule the PSSCH. The SCI can indicate transmission resources and reserve these resources for subsequent transmissions. The Physical Sidelink Feedback Channel (PSFCH) is used to feed back sidelink Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) information. After the UE determines the sidelink HARQ information, it can further transmit the sidelink HARQ information to the base station via PUCCH or PUSCH.

[0040] The synchronous resource configuration method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0041] The embodiments of this application can be applied to sidelink carrier aggregation scenarios. By configuring specific synchronization parameters and / or grouping S-SSBs and introducing interval parameters, the synchronization resources on each CC can be aligned when multiple CCs perform CA, avoiding the problems of high time domain occupancy of synchronization resources (i.e., low resource utilization) and transmission conflicts between synchronization signals and other signals, thereby improving resource utilization and ensuring the reliability of sidelink services.

[0042] This application provides a method for synchronizing resource configuration. Figure 2 A flowchart illustrating a method for synchronizing resource configuration according to an embodiment of this application is shown. Figure 2 As shown, the synchronous resource configuration method provided in this application embodiment may include the following steps 201 and 202.

[0043] Step 201: The UE determines the target configuration parameters.

[0044] Step 202: The UE transmits synchronization resources on at least two carriers according to the target configuration parameters.

[0045] In this embodiment of the application, the target configuration parameters are used for the transmission of synchronization resources on at least two carriers. The target configuration parameters include at least one of the following: target time information and target interval information. The target time information is used to indicate the target time. The target interval information includes at least one of the following: the interval of the target time and the interval of the synchronization resources. The target time includes at least the transmission time of the synchronization resources. The configuration parameters of the synchronization resources on at least two carriers are at least partially the same.

[0046] In this embodiment of the application, the aforementioned target time can be understood as the time available for transmitting synchronization resources on at least two carriers. Transmitting synchronization resources on at least two carriers can be understood as: sending synchronization resources on at least two carriers, or receiving synchronization resources on at least two carriers.

[0047] The statement that the configuration parameters of synchronization resources on at least two carriers are at least partially the same can be understood as: for synchronization resources on at least two carriers, the configuration parameters of the synchronization resources on these carriers are partially the same or completely identical.

[0048] For example, suppose there are at least two carriers, carrier 1, carrier 2, and carrier 3, and the configuration parameters include position, length, and SCS. The configuration parameters of the synchronization resources on these carriers (i.e., carrier 1, carrier 2, and carrier 3) are at least partially the same if: the position of the synchronization resource on carrier 1, the position of the synchronization resource on carrier 2, and the position of the synchronization resource on carrier 3 are the same; the length of the synchronization resource on carrier 1, the length of the synchronization resource on carrier 2, and the length of the synchronization resource on carrier 3 are the same; and the SCS of the synchronization resource on carrier 1, the SCS of the synchronization resource on carrier 2, and the SCS of the synchronization resource on carrier 3 are the same. Alternatively, the position of the synchronization resource on carrier 1, the position of the synchronization resource on carrier 2, and the position of the synchronization resource on carrier 3 are the same; the length of the synchronization resource on carrier 1, the length of the synchronization resource on carrier 2, and the length of the synchronization resource on carrier 3 are the same; and the SCS of the synchronization resource on carrier 1, the SCS of the synchronization resource on carrier 2, and the SCS of the synchronization resource on carrier 3 are different. Only these two cases are listed here to illustrate that the configuration parameters of the synchronization resources on carriers are at least partially the same; other cases are also included but will not be listed here.

[0049] Optionally, in the embodiments of this application, the above-mentioned synchronization resources can be a sidelink-synchronization signal block (S-SSB) or a group of S-SSBs.

[0050] It should be noted that an S-SSB group refers to at least one S-SSB located within a specific time period, constituting an S-SSB group. The S-SSBs within an S-SSB group can be continuous or discontinuous in the time domain.

[0051] Optionally, in this embodiment, the target configuration parameter is determined by any of the following: a first time, network-side device configuration, pre-configuration, indication from other user equipment, or UE-determined autonomously. The first time refers to the time range (or the length of the synchronization resources on at least two carriers) where the synchronization resources are located.

[0052] Optionally, in this embodiment of the application, the resources during the first time period are not included in the resource pool; or, the resources during the first time period are not used for the transmission of a specific channel / specific signal / specific signaling.

[0053] Optionally, in this embodiment of the application, the resources within the target time period are not included in the resource pool; or, the resources within the target time period are not used for the transmission of a specific channel / specific signal / specific signaling.

[0054] It should be noted that "resources within the first time period are not included in the resource pool" can be understood as: resources within the first time period are excluded when determining the resource pool, or resources within the first time period are not included in the resource pool. Similarly, "resources within the target time period are not included in the resource pool" can be understood as: resources within the target time period are excluded when determining the resource pool, or resources within the target time period are not included in the resource pool.

[0055] Optionally, in this embodiment of the application, resources that do not belong to the first time but belong to the target time are excluded when determining the resource pool.

[0056] Optionally, in the embodiments of this application, the aforementioned specific channel / specific signal / specific signaling may include at least one of the following: PSCCH, PSSCH, PSFCH, SCI, or Reference Signal (RS).

[0057] Optionally, in the embodiments of this application, the target time information includes at least one of the following: the length of the target time, the start point of the target time, the end point of the target time, and the SCS of the target time.

Wherein, the first carrier is a carrier selected by the UE from at least two carriers, the second carrier is the carrier with the longest first time among all carriers, and the first time is the time range in which the synchronization resources are located on at least two carriers.

[0059] Optionally, in this embodiment, the first carrier is determined by at least one of the following: the carrier's SCS, the carrier's priority, the carrier's synchronization priority order, the carrier's synchronization reference, the carrier's sidelink-synchronization signal (SLSS) identifier, the carrier's duplex mode, the number of carrier's synchronization resources, the number of carrier's S-SSBs, the carrier's frequency point, the carrier's frequency band / frequency range, the carrier's absolute radio frequency channel number (ARFCN), the carrier's global synchronization channel number (GSCN), the coverage status corresponding to the carrier, whether a base station / Global Navigation Satellite System (GNSS) is detected on the carrier, and the carrier's index.

[0065] It should be noted that the base station here is either a gNB or an eNB.

[0066] Optionally, in the embodiments of this application, the first carrier is any one of the following: the carrier with the smallest SLSS identifier, or the carrier with a specific SLSS identifier.

[0067] For example, the specific SLSS identifier (SLSS ID) mentioned above is 0, 1, 336 or 337.

[0068] Optionally, in the embodiments of this application, the first carrier mentioned above is any one of the following: a carrier with a duplex mode of Time Division Duplexing (TDD), a carrier with TDD configuration already acquired, a carrier in an unpaired band, a carrier with a duplex mode of Frequency Division Duplexing (FDD), a carrier without TDD configuration acquired, or a carrier in a paired band.

[0069] Optionally, in the embodiments of this application, the above-mentioned carrier corresponds to a specific TDD configuration or TDD pattern.

[0073] Optionally, in the embodiments of this application, the first carrier is any one of the following: the carrier with the lowest frequency, the carrier with the highest frequency, or the carrier with a specific frequency.

[0074] Optionally, in the embodiments of this application, the specific frequency point mentioned above is any one of the following: point A, the center frequency point / boundary frequency point of S-SSB, the center frequency point / boundary frequency point of the Bandwidth Part (BWP), and the center frequency point / boundary frequency point of the resource pool.

[0076] Optionally, in the embodiments of this application, the first carrier is any one of the following: the carrier with the smallest ARFCN, the carrier with the largest ARFCN, or the carrier with a specific ARFCN.

[0077] Optionally, in the embodiments of this application, the first carrier is any one of the following: the carrier with the smallest GSCN, the carrier with the largest GSCN, or the carrier with a specific GSCN.

[0078] Optionally, in the embodiments of this application, the first carrier is any one of the following: a carrier within the coverage area, or a carrier outside the coverage area.

[0079] Optionally, in the embodiments of this application, the first carrier mentioned above is any one of the following: a carrier that detects a base station (e.g., a base station that can detect sidelink services), or a carrier that detects GNSS (e.g., a carrier that can detect reliable GNSS).

[0080] Optionally, in the embodiments of this application, the first carrier is any one of the following: the carrier with the smallest index, the carrier with the largest index, or the carrier with a specific index.

[0081] Optionally, in the embodiments of this application, the first carrier mentioned above may specifically be a reference carrier, a synchronization carrier, or a primary carrier (PCC).

[0082] Optionally, in this embodiment of the application, the UE may obtain the aforementioned specific SCS / specific priority / specific SLSS ID / specific TDD configuration / TDD mode / specific number of synchronization resources / specific number of S-SSBs / specific frequency point / specific frequency band / frequency range / specific ARFCN / specific index, etc., based on network-side device configuration, pre-configuration, instructions from other user equipment, or the UE's own decision.

[0083] It should be noted that the UE selects only one carrier as the first carrier. If multiple carriers meet the above selection criteria for the first carrier, the choice depends on the UE implementation. For example, the UE may randomly select one carrier from the multiple carriers as the first carrier.

[0084] Optionally, in this embodiment, the starting point of the target time includes the starting point of the target time on the first carrier and the starting point of the target time on other carriers. The starting point of the target time on other carriers is obtained by a first distance, which is the distance between the starting point of the target time on other carriers and a first position. The first distance is determined by a second distance, which is the distance between the starting point of the target time on the first carrier and the first position. The first position is any one of the following: the position of Direct Frame Number 0 (DFN0) / System Frame Number 0 (SFN0) on the carrier, the starting point of the synchronization period on the carrier, or the ending point of the synchronization period on the carrier.

[0085] Optionally, in this embodiment, for the starting point of the target time, the UE can obtain the distance (i.e., the distance between the first position on the first carrier (i.e., the position of DFN0 / SFN0 / the start point / end point of the synchronization period / the end point of the synchronization period on the first carrier) and the starting point of the target time on the first carrier (i.e., the second distance, which can be called offsetstart1) according to the network-side device configuration, pre-configuration, instructions from other user equipment, or the UE's own decision, and calculate the distance (i.e., the distance between the first position on other carriers (i.e., the position of DFN0 / SFN0 / the start point / the end point of the synchronization period / the end point of the synchronization period on other carriers) and the starting point of the target time on those other carriers (i.e., the first distance, which can be called offsetstart1). i ),in, u1 is the subcarrier spacing factor corresponding to the first carrier, u i Let be the subcarrier spacing factor corresponding to carrier i.

[0086] It should be noted that the absolute length of the offset of each carrier in the time domain is equal, but since the SCS of each carrier may be different, the specific value of each offset may be different.

[0087] Optionally, in this embodiment, offsetstart1 is equal to the distance between the first position on the first carrier and the starting point of the first time on the first carrier.

[0088] Optionally, in this embodiment of the application, the endpoint of the target time includes the endpoint of the target time on the first carrier and the endpoint of the target time on other carriers. The endpoint of the target time on other carriers is obtained by a third distance, which is the distance between the endpoint of the target time on other carriers and the first position. The third distance is determined by a fourth distance, which is the distance between the endpoint of the target time on the first carrier and the first position.

[0089] Optionally, in this embodiment, for the endpoint of the target time, the UE can obtain the distance (i.e., the fourth distance, which can be called offsetend1) between the first position on the first carrier (i.e., the position of DFN0 / SFN0 / the start of the synchronization period / the end of the synchronization period on the first carrier) and the endpoint of the target time on the first carrier, based on network-side device configuration, pre-configuration, instructions from other user equipment, or the UE's own decision. Then, based on offsetend1, the UE calculates the distance (i.e., the third distance, which can be called offsetend1) between the first position on other carriers (i.e., the position of DFN0 / SFN0 / the start of the synchronization period / the end of the synchronization period on other carriers) and the endpoint of the target time on those other carriers. i ),in, u1 is the subcarrier spacing factor corresponding to the first carrier, u i Let be the subcarrier spacing factor corresponding to carrier i.

[0090] It should be noted that the absolute length of the offset of each carrier in the time domain is equal, but since the SCS of each carrier may be different, the specific value of each offset may be different.

[0091] Optionally, in this embodiment, offsetend1 is equal to the distance between the first position on the first carrier and the end point of the first time on the first carrier.

[0092] Optionally, in the embodiments of this application, the SCS of the target time satisfies any of the following: it is the same as the SCS of the first time on the first carrier; the SCS of the target time on each carrier is the same as the SCS of the first time on each carrier; it is the same as the largest SCS among all carriers; it is the same as the smallest SCS among all carriers; or it is a preset SCS.

[0093] It can be understood that the SCS of the target time on each carrier is the same as the SCS of the first time on the first carrier; or, the SCS of the target time on each carrier is the same as the SCS of the first time on its respective carrier, for example, the SCS of the target time on carrier 1 is the same as the SCS of the first time on carrier 1, and the SCS of the target time on carrier 2 is the same as the SCS of the first time on carrier 2; or, the SCS of the target time on each carrier is the same as the largest SCS among all carriers; or, the SCS of the target time on each carrier is the same as the smallest SCS among all carriers; or, the SCS of the target time on each carrier is a preset value.

[0094] Optionally, in the embodiments of this application, the target interval information is determined by at least one of the following: specific interval information, grouping information of synchronization resources, common interval information, reference interval information, and SCS of the carrier.

[0095] Optionally, in the embodiments of this application, the aforementioned specific interval information includes at least one of the following:

[0096] Only one S-SSB is transmitted within a transmission cycle;

[0097] The number of S-SSBs within each synchronization resource is one;

[0098] There is only one target time within the transmission cycle;

[0099] The target time interval does not exist;

[0100] The interval for group S-SSB does not exist;

[0101] There is no interval between S-SSBs within the S-SSB group;

[0102] The number of S-SSB groups is 1.

[0103] It should be noted that the absence of intervals (i.e., intervals such as interval1, interval2, and interval3 in the following embodiments) in the embodiments of this application can be understood as follows: when there is only one target time or only one S-SSB / S-SSB group within a period, the concept of 'interval' does not exist. Therefore, the interval can also be configured to a specified value, such as an interval of 0.

[0104] It is understandable that the UE can configure, pre-configure, be instructed by other user equipment, or decide autonomously through network-side equipment to ensure that only one S-SSB is transmitted on the carrier transmitting the synchronization signal in one cycle, and / or that the number of S-SSBs in each synchronization resource is 1, and / or that there is only one target time in the cycle, and / or that the interval of the target time (which can be called interval1) does not exist, and / or that the interval of the S-SSB group (which can be called interval2) does not exist, and / or that the interval of S-SSBs within the S-SSB group (which can be called interval3) does not exist, and / or that the number of S-SSB groups (syncgroupnum) is 1.

[0105] For example, such as Figure 3 As shown, carriers 1, 2, and 3 undergo CA (Compatibility Alignment). Assuming a synchronization period of 160ms, the SCS (Search Channel Size) of carrier 1 is 15kHz, the SCS of carrier 2 is 30kHz, and the SCS of carrier 3 is 60kHz. The number of S-SSBs transmitted within the synchronization period of each carrier is configured to be 1. The UE sets the target time length to the longest first time on each carrier. At this time, intervals 1, 2, and 3 on each carrier do not exist, and the number of S-SSB groups within each synchronization period of each carrier is 1.

[0106] Optionally, in the embodiments of this application, in the first case, the above-mentioned target interval information satisfies at least one of the following:

[0107] The target time interval does not exist;

[0108] The interval for group S-SSB does not exist;

[0109] The spacing of S-SSBs within an S-SSB group satisfies the following conditions: there is no spacing of S-SSBs within an S-SSB group on a carrier that transmits one S-SSB in one period, or the spacing of S-SSBs within an S-SSB group is 0 on a carrier that transmits multiple S-SSBs in one period (that is, the S-SSBs in one period are configured on consecutive slots).

[0110] Among them, the first case mentioned above satisfies the following: the grouping information of the synchronization resources is used to indicate that when there are at least two carriers transmitting multiple S-SSBs in one period, the number of S-SSB groups transmitted by each carrier in one period is configured to be 1.

[0111] It is understandable that in this method, when there are at least two carriers transmitting multiple S-SSBs in one cycle, the UE makes the number of S-SSB groups transmitted by each carrier in one cycle 1, and at this time the target spacing information satisfies at least one of the above.

[0112] For example, such as Figure 4 As shown, carriers 1, 2, and 3 undergo CA (Compatibility Analysis). Assuming a synchronization period of 160ms, the SCS (Search Channel Size) of carrier 1 is 15kHz, the SCS of carrier 2 is 30kHz, and the SCS of carrier 3 is 60kHz. The number of S-SSBs transmitted within the synchronization period of carriers 1, 2, and 3 are configured as 1, 2, and 2, respectively. The UE sets the target time to the longest first time on each carrier. At this time, interval1 and interval2 on each carrier do not exist, interval3 on carrier 1 does not exist, and interval3 on carriers 2 and 3 is 0. The number of S-SSB groups within each synchronization period on each carrier is 1.

[0113] Optionally, in the embodiments of this application, in the second case, the above-mentioned target interval information satisfies at least one of the following:

[0114] The target time interval satisfies the following: if there is a carrier in at least two carriers that transmits only one S-SSB in a period, then the target time interval does not exist; or, if there is no carrier that transmits only one S-SSB in a period, then the target time interval is configured, pre-configured, pre-defined by the network-side equipment, determined autonomously by the UE, or indicated by other UEs.

[0115] The S-SSB group interval satisfies the following: if there is a carrier in at least two carriers that transmits only one S-SSB in one period, then the S-SSB group interval does not exist; or, if there is no carrier that transmits only one S-SSB in one period, then the S-SSB group interval is the same as the target time interval (i.e., interval2 = interval1).

[0116] The spacing of S-SSBs within an S-SSB group satisfies the following: If there is a carrier in at least two carriers that transmits only one S-SSB in one period, then the spacing of S-SSBs within the S-SSB group on the carrier that transmits only one S-SSB in one period does not exist, or the spacing of S-SSBs within the S-SSB group on the carrier that transmits multiple S-SSBs in one period is 0; if there is no carrier that transmits only one S-SSB in one period, then the spacing of S-SSBs within the S-SSB group on each carrier is 0 (that is, the S-SSBs within an S-SSB group are configured on consecutive slots).

[0117] The number of S-SSBs in an S-SSB group satisfies the following: the number of S-SSBs in each S-SSB group on any carrier (e.g., carrier i) is the ratio of the number of S-SSBs transmitted on that carrier in one period to the number of S-SSB groups.

[0118] In the second case mentioned above, the grouping information of the synchronization resources is used to indicate that when there are at least two carriers transmitting multiple S-SSBs in one period, the number of S-SSB groups transmitted by each carrier in one period is configured as a first value, which is the number of S-SSBs transmitted on the third carrier in one period, and the third carrier is the carrier with the smallest number of S-SSBs transmitted in one period.

[0119] Optionally, in the embodiments of this application, in the second case, the target interval information satisfies at least one of the following:

[0120] The target time interval satisfies the following conditions: if only one S-SSB is transmitted on one of the at least two carriers in a period, then the target time interval does not exist; or, if multiple S-SSBs are transmitted on each of the at least two carriers in a period, then the target time interval is configured, pre-configured, pre-defined, determined autonomously by the UE, or indicated by other UEs.

[0121] The spacing of an S-SSB group satisfies the following conditions: if only one S-SSB is transmitted on one of the carriers of at least two carriers in one period, then the spacing of the S-SSB group does not exist; or, if multiple S-SSBs are transmitted on each of the at least two carriers in one period, then the spacing of the S-SSB group is the same as the spacing of the target time.

[0122] The spacing of S-SSBs within an S-SSB group satisfies the following conditions: if only one S-SSB is transmitted on a carrier of at least two carriers in one period, then the spacing of S-SSBs within the S-SSB group on the carrier that transmits only one S-SSB in one period does not exist, or the spacing of S-SSBs within the S-SSB group on the carrier that transmits multiple S-SSBs in one period is 0; if each of the at least two carriers transmits multiple S-SSBs in one period, then the spacing of S-SSBs within the S-SSB group on each carrier is 0.

[0123] The number of S-SSBs within an S-SSB group satisfies the following condition: the number of S-SSBs contained in each S-SSB group on any carrier is the ratio of the number of S-SSBs transmitted on any carrier in one period to the number of S-SSB groups.

[0124] Understandably, in this approach, when at least two carriers transmit multiple S-SSBs within a single period, the UE sets the number of S-SSB groups transmitted by each carrier within a single period to a first value (which can be referred to as min L). i ), L i Let be the number of S-SSBs transmitted in one period on carrier i, where the target spacing information satisfies at least one of the above conditions.

[0125] For example, such as Figure 5 As shown, carriers 1, 2, and 3 undergo CA (synchronization algorithm). Assuming a synchronization period of 160ms, the SCS (Search Channel Counter) of carrier 1 is 30kHz, the SCS of carrier 2 is 60kHz, and the SCS of carrier 3 is 60kHz. The number of S-SSBs transmitted within the synchronization period of carriers 1, 2, and 3 are configured as 2, 4, and 8, respectively. The UE sets the target time length to the longest first time on each carrier. At this time, the number of S-SSB groups transmitted by each carrier in one period = min L. i =2, interval1 = interval2 on each carrier, interval3 on each carrier is 0, the number of S-SSBs in each S-SSB group on carrier 1 is 1, the number of S-SSBs in each S-SSB group on carrier 2 is 2, and the number of S-SSBs in each S-SSB group on carrier 3 is 4.

[0126] In this embodiment of the application, the UE can ensure the alignment of synchronization resources on each carrier by configuring specific S-SSBs or grouping S-SSBs. At this time, no carrier needs to discard S-SSBs or send virtual S-SSBs (e.g., padding information at the corresponding position).

[0127] Optionally, in this embodiment of the application, the target interval information is determined by the common interval information, including: the common interval information is configured, pre-configured, pre-defined by the network-side equipment, indicated by other user equipment, or determined autonomously by the UE, and the interval information of at least two carriers is the same as the common interval information.

[0128] It is understandable that the UE can obtain the common interval information in the above manner and set the interval information of at least two carriers to be the same as the common interval information.

[0129] Optionally, in this embodiment of the application, the UE may use the spacing information of the first carrier as common spacing information, which includes at least one of the following: SCS of S-SSB, number of S-SSBs, number of S-SSB groups, target time interval, and S-SSB interval (e.g., interval2 of S-SSB group, interval3 of S-SSB within S-SSB group).

[0130] For example, such as Figure 6 As shown, carriers 1, 2, and 3 undergo CA (synchronization alignment). Assuming a synchronization period of 160ms, the SCS (Sequence Size Class) of carrier 1 is 15kHz, the SCS of carrier 2 is 30kHz, and the SCS of carrier 3 is 60kHz. The original configurations of the number of S-SSBs transmitted during the synchronization period of carriers 1, 2, and 3 are 2, 2, and 1, respectively. The UE selects carrier 2 as the first carrier and uses the spacing information of carrier 2 as the common spacing information. The spacing information on each carrier is set to be the same as the common spacing information. Therefore, the number of S-SSBs transmitted during the synchronization period of carriers 1 and 3 both become 2, and the SCS of the S-SSBs also becomes 30kHz. At this time, the synchronization resources of each carrier remain aligned (at this point, it is not necessary to use target time to ensure synchronization resource alignment).

[0131] In this embodiment, the UE can obtain common interval information (i.e., common S-SSB / S-SSB group configuration) through network-side device configuration, pre-configuration, instructions from other user equipment, or independent decision by the UE, and apply it to all carriers. At this time, the configuration of S-SSBs (such as the number and interval) on each carrier is the same, thereby ensuring the alignment of synchronization resources on each carrier.

[0132] Optionally, in this embodiment of the application, the target interval information is determined by reference interval information, including at least one of the following:

[0133] If a first synchronization resource exists in the synchronization resources to be transmitted on the fourth carrier, the first synchronization resource or all synchronization resources are not transmitted; the first synchronization resource is a synchronization resource that is not within the time determined by the reference interval information.

[0134] When a second time exists on the fifth carrier and the second time is aligned with the time determined by the reference interval information, the information transmitted in the second time is padding information or specific information; the second time is the time when no synchronization resources are transmitted on the fifth carrier.

[0135] It is understood that if the first synchronization resource exists in the synchronization resources to be transmitted on the fourth carrier, the UE will not transmit the first synchronization resource or will not transmit all synchronization resources; and / or, if a second time exists on the fifth carrier and the second time is aligned with the time determined by the reference interval information, the UE will transmit padding information or specific information at the second time.

[0136] Optionally, in this embodiment of the application, the UE may use the spacing information of the first carrier as reference spacing information, which includes at least one of the following: SCS of S-SSB, number of S-SSBs, number of S-SSB groups, target time interval, and S-SSB interval (e.g., interval2 of S-SSB group, interval3 of S-SSB within S-SSB group).

[0137] Understandably, in one approach, for any carrier, if there exists an S-SSB / S-SSB group (i.e., the first synchronization resource) that needs to be transmitted on that carrier, and it is not at the same time (e.g., the target time) as the S-SSB / S-SSB group determined by the reference interval information, then the UE will not transmit the first synchronization resource or will not transmit all S-SSB / S-SSB groups.

[0138] For example, such as Figure 7 As shown, carriers 1 and 2 perform CA (synchronization algorithm). Assuming a synchronization period of 160ms, the SCS (Search Channel Scale) of carrier 1 is 30kHz, and the SCS of carrier 2 is 60kHz, the original configurations for the number of S-SSBs transmitted within the synchronization period of carriers 1 and 2 are 1 and 2, respectively. The UE uses the first time on carrier 1 as the target time and the interval information of carrier 1 as the reference interval information, setting the interval information on each carrier to be the same as the reference interval information. Therefore, carrier 2 needs to discard the transmission of S-SSBs that do not belong to the target time (i.e.,...). Figure 7 (S-SSB2 shown in the figure).

[0139] It is understandable that, in another way, for any carrier, if there is a second time (i.e., a time when no S-SSB / S-SSB group is transmitted) and it is aligned with the S-SSB / S-SSB group configuration determined by the reference interval information, then the UE can start transmitting virtual S-SSB / S-SSB groups (i.e., padding information (e.g., redundancy information) or specific information) from the start of the second time.

[0140] For example, such as Figure 8As shown, carriers 1 and 2 perform CA (synchronization algorithm). Assuming a synchronization period of 160ms, the SCS (Search Channel Scale) of carrier 1 is 30kHz, and the SCS of carrier 2 is 60kHz, the original configurations for the number of S-SSBs transmitted within the synchronization period of carriers 1 and 2 are 1 and 2 respectively. The UE uses the first time on carrier 1 as the target time and the interval information of carrier 2 as the reference interval information, setting the interval information on each carrier to be the same as the reference interval information. Therefore, carrier 1 needs to transmit a virtual S-SSB (i.e., ...) starting from the second time. Figure 8 (S-SSB2 shown in the figure).

[0141] It should be noted that, for the above-mentioned schemes of common interval information and reference interval information, the scheme of common interval information directly applies the common interval information to all carriers, while the scheme of reference interval information, based on the original interval information of each carrier, discards the synchronization resources on some carriers or sends virtual synchronization resources on some carriers, so that the synchronization resources on each carrier are at the same time as the synchronization resources determined by the reference interval information.

[0142] In this embodiment, the UE can determine the reference interval information (i.e., the reference S-SSB / S-SSB group configuration) based on the network-side device configuration, pre-configuration, instructions from other user equipment, or the UE's own decision. Then, it compares the S-SSB / S-SSB group configuration on each carrier with the reference interval information. By discarding S-SSBs on some carriers or sending virtual S-SSBs on some carriers, the synchronization resources on each carrier are made to be at the same time as the synchronization resources determined by the reference interval information, thereby ensuring the alignment of the synchronization resources on each carrier.

[0143] Optionally, in this embodiment of the application, the target interval information is determined by the SCS of the carrier, including the following: determined by the configuration parameters of the synchronization resources on the first carrier, and the number of synchronization resources on different carriers is a preset value.

[0144] It should be noted that the aforementioned different carriers can be carriers of different SCSs or carriers with different attributes. The specific carriers can be determined according to the usage requirements, and this application embodiment does not impose any restrictions.

[0145] Understandably, in one approach, the UE can determine the first carrier based on network-side device configuration, pre-configuration, instructions from other user equipment, or the UE's own decision, and determine the configuration of synchronization resources on other carriers based on the configuration of synchronization resources on the first carrier, so that the time length occupied by synchronization resources on each carrier is the same.

[0146] Optionally, in this embodiment of the application, the number of S-SSBs on carrier i is ssbnum. i for: Where u1 is the subcarrier spacing factor corresponding to the first carrier, u i ssbnum1 is the subcarrier spacing factor corresponding to carrier i, and ssbnum1 is the number of SSBs on the first carrier.

[0147] Understandably, another approach is for the UE to set the number of synchronization resources on carriers with different SCSs to fixed values, ensuring that the synchronization resources occupy the same amount of time on each carrier. For example, the number of S-SSBs on a carrier with SCS=15kHz could be configured as 1, the number of S-SSBs on a carrier with SCS=30kHz as 2, and the number of S-SSBs on a carrier with SCS=60kHz as 4. Alternatively, the number of S-SSBs on a carrier with SCS=15kHz could be configured as 2, the number of S-SSBs on a carrier with SCS=30kHz as 4, and the number of S-SSBs on a carrier with SCS=60kHz as 8.

[0148] For example, such as Figure 9 As shown, carriers 1, 2 and 3 perform CA. Assuming the synchronization period is 160ms, the SCS of carrier 1 is 15kHz, the SCS of carrier 2 is 30kHz, and the SCS of carrier 3 is 60kHz. The number of S-SSBs transmitted within the synchronization period of carriers 1, 2 and 3 are configured to be 1, 2 and 4 respectively. At this time, the first time on any carrier can be used as the second time, and the synchronization resources of each carrier remain aligned.

[0149] In this embodiment of the application, since the SCS of each carrier may be different, the synchronization resources of the corresponding carrier can be configured according to the SCS of the carrier so that the synchronization resources on each carrier are aligned.

[0150] Optionally, in this embodiment of the application, the target configuration parameter further includes first information, which is used to indicate whether synchronization resources are configured on the carrier. The first information includes at least one of the following: configuring synchronization resources only on the first carrier, configuring synchronization resources on all carriers used for CA transmission, configuring synchronization resources on carriers actually used for CA transmission, configuring synchronization resources only on carriers in the first set, and configuring synchronization resources only on carriers in the second set.

[0151] Optionally, in this embodiment of the application, the first information is further used to indicate that the number of synchronization resources on carriers configured with synchronization resources is the same.

[0152] Optionally, in the embodiments of this application, the first set can be Set A (carriers that can potentially be used as the synchronization carrier), and the second set can be Set B (the available set of synchronization carriers).

[0153] Optionally, in this embodiment of the application, the target configuration parameters mentioned above further include synchronization resource content (S-SSBcontent), which includes at least one of the following: DFN, slot index, in-coverage, duplex configuration, and SLSS identifier.

[0154] Optionally, in the embodiments of this application, the duplex configuration mentioned above includes at least one of the following: TDD configuration and FDD configuration.

[0155] Optionally, in the embodiments of this application, the DFN value in the above-mentioned synchronization resource is the same as or different from the DFN value in the synchronization resource on the first carrier, or it is a preset value.

[0156] Optionally, in the embodiments of this application, the time slot index value in the above-mentioned synchronization resource may be the same as or different from the time slot index value in the synchronization resource on the first carrier, or it may be a preset value.

[0157] Optionally, in the embodiments of this application, the coverage value in the above-mentioned synchronization resources may be the same as or different from the coverage value in the synchronization resources on the first carrier, or it may be a preset value.

[0158] Optionally, in the embodiments of this application, the TDD configuration in the above-mentioned synchronization resources may be the same as or different from the TDD configuration in the synchronization resources on the first carrier, or may be a preset value.

[0159] Optionally, in the embodiments of this application, the SLSS identifier in the above-mentioned synchronization resources may be the same as or different from the SLSS identifier in the synchronization resources on the first carrier, or it may be a preset value.

[0160] It is understood that the DFN value in the S-SSB on each carrier may be the same as or different from the DFN value in the S-SSB on the first carrier, or may be a preset value; and / or, the slot index value in the S-SSB on each carrier may be the same as or different from the slotindex value in the S-SSB on the first carrier, or may be a preset value; and / or, the in-coverage value in the S-SSB on each carrier may be the same as or different from the in-coverage value in the S-SSB on the first carrier, or may be a preset value; and / or, the TDD configuration in the S-SSB on each carrier may be the same as or different from the TDD configuration in the S-SSB on the first carrier, or may be a preset value; and / or, the SLSS ID in the S-SSB on each carrier may be the same as or different from the SLSS ID in the S-SSB on the first carrier, or may be a preset value.

[0161] Optionally, in this embodiment of the application, the carrier synchronization method for the above-mentioned at least two carriers includes at least one of the following: timing synchronization and transmission direction synchronization. Timing synchronization involves using the synchronization reference source corresponding to the first carrier as the synchronization reference for other carriers; transmission direction synchronization involves using the transmission direction of the synchronization resource on the first carrier as the transmission direction of the target synchronization resource on other carriers, where the target synchronization resource is the synchronization resource on other carriers that is aligned with the synchronization resource of the first carrier.

[0162] It is understandable that, for timing synchronization, the UE can use the synchronization reference source corresponding to the first carrier as the synchronization reference for other carriers. It should be noted that the above timing synchronization can be understood as: determining the timing of other carriers based on the timing corresponding to the first carrier.

[0163] For transmission direction synchronization: The UE can determine the transmission direction of the synchronization resources on the first carrier based on the network-side device configuration, pre-configuration, instructions from other user equipment, or the UE's own decision, and set the transmission direction of the synchronization resources on other carriers that are aligned with the synchronization resources of the first carrier to be the same as the first carrier.

[0164] Optionally, in the embodiments of this application, the above-mentioned timing synchronization includes at least one of the following: frame boundary alignment, subframe boundary alignment, time slot boundary alignment, symbol boundary alignment, and second / millisecond / microsecond level alignment.

[0165] Optionally, in the embodiments of this application, the above-mentioned frame boundary alignment can be that the frame indices are the same or different; the subframe boundary alignment can be that the subframe indices are the same or different; the time slot boundary alignment can be that the time slot indices are the same or different; the symbol boundary alignment can be that the symbol indices are the same or different; and the second / millisecond / microsecond level alignment can be that the second / millisecond / microsecond indices are the same or different.

[0166] Optionally, in the embodiments of this application, the other carriers mentioned above are any of the following: all carriers used for CA transmission, carriers actually used for CA transmission, carriers configured with synchronization resources, carriers in the first set, and carriers in the second set.

[0167] In this embodiment of the application, the UE can first use the above method to synchronize at least two carriers, and then determine the target configuration parameters so that the synchronization resources on each carrier unit are aligned.

[0168] Optionally, in this embodiment of the application, the UE transmits synchronization signals for synchronization resources on at least two carriers in any of the following ways:

[0169] The UE transmits the synchronization signal only on the first carrier.

[0170] The UE determines whether to transmit a synchronization signal on each carrier based on the values ​​of the spacing information on at least two carriers;

[0171] When the transmission exceeds the UE's capabilities, the UE autonomously decides which carrier to transmit the synchronization signal.

[0172] It is understood that the UE transmits the synchronization signal on at least the first carrier. In one approach, when only one carrier is allowed to transmit the synchronization signal on the synchronization resource, the UE may transmit the synchronization signal on the first carrier; in another approach, when multiple carriers are allowed to transmit the synchronization signal on the synchronization resource, the UE may decide whether to transmit the synchronization signal on its respective carrier based on the value of the spacing information on at least two carriers.

[0173] For example, if the value of the interval information on carrier 1 is 1, then the UE transmits a synchronization signal on carrier 1; if the value of the interval information on carrier 1 is 0, then the UE does not transmit a synchronization signal on carrier 1.

[0174] It should be noted that when the transmission exceeds the UE's capabilities (e.g., exceeding the upper limit of the number of transmission carriers), the UE autonomously decides which carrier to transmit the synchronization signal, for example, the UE randomly selects from the carriers that meet the transmission conditions.

[0175] In this embodiment of the application, after determining the target configuration parameters, the UE may transmit the synchronization signal only on the first carrier, or determine the carrier for transmitting the synchronization signal according to the UE's capabilities, or transmit the synchronization signal on synchronization resources on at least two carriers according to the target configuration parameters.

[0176] Optionally, in the embodiments of this application, the relationship between the synchronization resources on the above-mentioned at least two carriers and the Discontinuous Reception (DRX) mechanism includes at least one of the following:

[0177] The target time and the DRX activation time at least partially overlap;

[0178] The target time interval is an integer multiple of the DRX period, or the DRX period is an integer multiple of the target time interval;

[0179] The first time overlaps at least partially with the DRX activation time;

[0180] The first time interval is an integer multiple of the DRX period, or the DRX period is an integer multiple of the first time interval;

[0181] The period of the synchronization resource is an integer multiple of the DRX period, or the DRX period is an integer multiple of the period of the synchronization resource.

[0182] First time / target time / synchronized resources are located before the DRX activation time;

[0183] Allows the UE to transmit synchronization signals on synchronization resources located during DRX inactivity periods;

[0184] UEs are not allowed to transmit synchronization signals on synchronization resources located during DRX inactive periods.

[0185] Optionally, in this embodiment of the application, the target time and DRX activation time at least partially overlapping includes at least one of the following: the start point of the target time is the same as the start point of the DRX activation time; the end point of the target time is the same as the end point of the DRX activation time; the first overlap length is greater than or equal to a first preset threshold; and the ratio of the first overlap length to the target time / DRX activation time / DRX cycle is greater than or equal to a second preset threshold. Wherein, the first overlap length is the overlap length between the target time and the DRX activation time.

[0186] Optionally, in this embodiment of the application, the aforementioned first time and DRX activation time at least partially overlap includes at least one of the following: the start point of the first time is the same as the start point of the DRX activation time; the end point of the first time is the same as the end point of the DRX activation time; the second overlap length is greater than or equal to a third preset threshold; and the ratio of the second overlap length to the first time / DRX activation time / DRX period is greater than or equal to a fourth preset threshold. Wherein, the second overlap length is the overlap length between the first time and the DRX activation time.

[0187] Optionally, in this embodiment of the application, the interval of the target time is equal to the DRX period; the interval of the first time is equal to the DRX period; and the period of the S-SSB / S-SSB group is equal to the DRX period.

[0188] Optionally, in this embodiment of the application, for the first time / target time / synchronization resource being located before the DRX activation time, specifically, the distance between the end point of the first time / second time / S-SSB / S-SSB group and the start point of the DRX activation time is greater than a preset threshold.

[0189] It should be noted that DRX active time can be understood as the time during which the UE listens to / receives / demodulates / measures a specific channel / signal / signaling (i.e., the active period). DRX active time can include at least one of the following: DRX on duration, inactivity timer runtime, and retransmission timer runtime.

[0190] DRX inactive time can be understood as the time during which the UE does not listen to / receive / demodulate / measure a specific channel / signal / signaling (i.e., sleep period). DRX inactive time may include at least one of the following: DRX off duration, Round Trip Time (RTT) timer runtime.

[0191] Optionally, in the embodiments of this application, the specific channel / signal / signaling mentioned above may include at least one of the following: PSCCH, PSSCH, Physical Sidelink Broadcast Channel (PSBCH), PSFCH, SCI, S-SSB, RS.

[0192] This application provides a synchronization resource configuration method. A UE can determine target configuration parameters for the transmission of synchronization resources on at least two carriers. These target configuration parameters include target time information and / or target interval information, and the configuration parameters of the synchronization resources on at least two carriers are at least partially identical. In this scheme, when multiple carrier units perform carrier aggregation, the UE can determine the target time, the target time interval, and / or the interval of the synchronization resources on each carrier for transmission. Since the determined configuration parameters of the synchronization resources on these carriers are partially identical or completely identical, the synchronization resources on each carrier unit can be aligned, avoiding high time-domain occupancy of synchronization resources and transmission conflicts between synchronization signals and other signals. This improves resource utilization and ensures the reliability of sidelink services.

[0193] It should be noted that the synchronization resource configuration method provided in this application embodiment can be executed by a UE, a synchronization resource configuration device, or a control module in the synchronization resource configuration device for executing the synchronization resource configuration method. This application embodiment uses the execution of the synchronization resource configuration method by a UE as an example to illustrate the synchronization resource configuration device provided in this application embodiment.

[0194] Figure 10 A schematic diagram of a possible structure of the synchronization resource configuration device involved in an embodiment of this application is shown. For example... Figure 10 As shown, the synchronous resource configuration device 60 may include: a determination module 61.

[0195] The determining module 61 is used to determine target configuration parameters for the transmission of synchronization resources on at least two carriers. The target configuration parameters include at least one of the following: target time information and target interval information. The target time information is used to indicate the target time. The target interval information includes at least one of the following: the interval of the target time and the interval of the synchronization resources. The target time includes at least the transmission time of the synchronization resources. The configuration parameters of the synchronization resources on at least two carriers are at least partially the same.

[0196] In one possible implementation, the target time information mentioned above includes at least one of the following: the length of the target time, the start point of the target time, the end point of the target time, and the SCS of the target time.

[0197] In one possible implementation, the length of the target time is any one of the following: the length of the first time on the first carrier, the length of the first time on the second carrier, or a preset length, wherein the second carrier is the carrier with the longest first time among all carriers; the first time is the time range in which the synchronization resources on at least two carriers are located;

[0198] And / or,

[0199] The starting point of the target time mentioned above includes the starting point of the target time on the first carrier and the starting point of the target time on other carriers. The starting point of the target time on other carriers is obtained by a first distance, which is the distance between the starting point of the target time on other carriers and the first position. The first distance is determined by a second distance, which is the distance between the starting point of the target time on the first carrier and the first position.
