[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on September 12, 2023, with application number 202311180986.0 and invention name “A carrier aggregation method, system, electronic device and storage medium”. The entire contents of the Chinese patent application are incorporated herein by reference. Technical Field

[0003] The present application relates to the field of wireless communication technologies, and in particular to a carrier aggregation method, system, electronic device, and storage medium. Background Art

[0004] With the continuous advancement of radio technology, a wide variety of radio services have emerged. In addition to cellular services between base stations and terminals, Long Term Evolution (LTE) and New Radio (NR) systems also include vehicle-to-anything (V2X) services. The link for V2X service communication is called the sidelink (SL). The main channels include the Physical Sidelink Control Channel (PSCCH) and the Physical Sidelink Shared Channel (PSSCH). The PSCCH carries sidelink control information, and the PSSCH carries service data. When services are transmitted between devices, the service data between the devices is not forwarded by other network devices, but is transmitted directly from the data source device to the target device, i.e., direct communication between devices. It can be understood that this device can refer to user equipment (UE) with V2X capabilities. SL can be divided into three main communication scenarios: the first scenario (in coverage), in which both the data source device and the target device are within the coverage of the base station; the second scenario (partial coverage), in which one of the data source device and the target device is within the coverage of the base station and the other is outside the coverage of the base station; the third scenario (out of coverage), in which both the data source device and the target device are outside the coverage of the base station. SL can be divided into two main communication modes: the first communication mode, in which the resources for the device to send SL signals come from the scheduling of the base station, which can be recorded as mode 3 in LTE and mode 1 in NR. The second communication mode, in which the device is in the network or in a pre-configured resource pool, and autonomously selects resources from the resource pool according to the resource selection strategy, which includes the sensing mechanism, partial sensing mechanism, and random selection mechanism. The second communication mode can be recorded as mode 4 in LTE and mode 2 in NR.

[0005] With the advancement of technology, carrier aggregation (CA) needs to be considered in V2X deployment scenarios. The frequency of each component carrier (CC) of CA varies greatly, and the channel conditions or communication requirements of these CCs also vary greatly. How to determine the relevant information of carrier aggregation in V2X deployment scenarios has become an urgent problem that needs to be solved.

[0018] It should be understood that the specific implementations described herein are only used to explain the present application and are not used to limit the present application.

[0019] In the subsequent description, suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of this application and have no specific meaning. Therefore, "module", "component" or "unit" can be used interchangeably.

[0020] Figure 1 is a flowchart of a carrier aggregation method provided in an embodiment of the present application. The present application can be applied to the determination of carrier aggregation related information in a V2X deployment scenario. The method can be executed by a carrier aggregation device, which can be implemented by software and / or hardware. Referring to Figure 1, the method provided in an embodiment of the present application includes the following steps.

[0021] Step 110: The first entity determines a carrier group and carriers included in the carrier group through configuration or pre-configuration.

[0022] In an embodiment of the present application, the first entity may be an entity that determines carrier aggregation-related information within a carrier aggregation system. The first entity may include one or more of a network node, a terminal node, a wireless resource control layer, a wireless link control layer, a media access control layer, and a physical layer. The carrier group may be a combination of carriers for carrier aggregation. The carrier group may be determined by configuration or pre-configuration in the first entity. It can be understood that the carriers included in each carrier group can also be determined by configuration or pre-configuration in the first entity.

[0023] Furthermore, based on the above application embodiment, the first entity includes at least one of the following: a network node, a terminal node, a radio resource control layer, a radio link control layer, a media access control layer, and a physical layer.

[0024] In an embodiment of the present application, the carrier aggregation system can determine the carrier group and the carriers included in each carrier group through configuration or pre-configuration in entities such as network nodes, terminal nodes, wireless resource control layer, wireless link control layer, media access control layer, and physical layer.

[0025] In some application embodiments, the number of carrier groups is configured based on at least one bit, and the number of bits is determined by the maximum number of carrier groups.

[0026] In an embodiment of the present application, the first entity may configure one or more bits to indicate the number of carrier groups of the carrier group by configuration or pre-configuration, and the number of bits of the configuration may be determined by the maximum number of carrier groups of the carrier group. For example, each bit may identify a carrier group, and the bit of the maximum number of carrier groups of the carrier group may be configured to indicate the number of carrier groups of the carrier group. For another example, a binary value consisting of one or more bits may be used to represent the number of carrier groups of the carrier group, and binary "00", "01", "10", and "11" represent that the number of carrier groups is 1 carrier group, 2 carrier groups, 3 carriers, and 4 carriers, respectively. Then the number of bits may be determined by N=log2(M), where N is the number of carrier groups, and M may identify the maximum number of carrier groups.

[0027] In an exemplary embodiment, N bits may be configured to indicate the number of carrier groups of a carrier group. The value of N may be determined by N=log2(M), where M represents the maximum number of carrier groups. Assuming M=4, 2 binary bits are required. Binary "00", "01", "10", and "11" represent that the number of carrier groups is 1 carrier group, 2 carrier groups, 3 carriers, and 4 carriers, respectively. When the number of carrier groups is configured or pre-configured as "00", it indicates that all carriers participating in carrier aggregation are divided into 1 carrier group, and the carrier group indices are CG0; when the number of carrier groups is configured or pre-configured as "01", it indicates that all carriers participating in carrier aggregation are divided into 2 carrier groups, and the carrier group indices are CG0 and CG1, respectively; when the number of carrier groups is configured or pre-configured as "10", it indicates that all carriers participating in carrier aggregation are divided into 3 carrier groups, and the carrier group indices are CG0, CG1, and CG2, respectively; when the number of carrier groups is configured or pre-configured as "11", it indicates that all carriers participating in carrier aggregation are divided into 4 carrier groups, and the carrier group indices are CG0, CG1, CG2, and CG3, respectively.

[0028] In some application embodiments, the carriers included in the carrier group are determined according to a carrier index or a cell index.

[0029] In an embodiment of the present application, when the first entity determines the carriers included in the carrier group, it can be determined by the carrier index or cell index. For example, assuming that the carrier index or cell index is C0, C1, C2, ..., C9, and the number of carrier groups is configured or preset as "01", that is, all carriers participating in carrier aggregation are divided into two carrier groups, and the carrier group indexes are CG0 and CG1 respectively. The carrier index or cell index included in the configuration or pre-configuration CG0 is {C0, C5, C6}, and the carrier index or cell index included in the configuration or pre-configuration CG1 is {C1}, then the carriers included in each carrier group can be determined by the carrier index or cell index.

[0030] In some application embodiments, the method further includes: enabling or disabling the carrier group function through at least one of configuration or pre-configuration.

[0031] In one embodiment, the carrier group function can be enabled or disabled by configuration or pre-configuration. For example, a carrier aggregation function enable indicator bit or a disable indicator bit can be configured or pre-configured. The binary "0" corresponding to the carrier group function enable or disable signaling on the above indicator bit indicates that the carrier group function is enabled; the binary "1" indicates that the carrier group function is disabled.

[0032] In some application embodiments, the method further includes: determining a group level through configuration or pre-configuration, wherein the group level includes at least one of a carrier group level and a frequency band level.

[0033] In an embodiment of the present application, the group level of the carrier group can also be determined. The group level can be determined by configuration or pre-configuration, where the group level can include the carrier group level and the frequency band level, etc.

[0034] In an exemplary embodiment, the group level can be determined by configuration or pre-configuration. For example, the binary "0" corresponding to the group level signaling represents the carrier group level, that is, several carriers correspond to 1 carrier group; the binary "1" represents the frequency band level, that is, 1 frequency band corresponds to 1 carrier group.

[0035] In some application embodiments, the carriers included in the carrier group are configured with at least one partial bandwidth.

[0036] In the embodiment of the present application, the flexibility of the bandwidth part (BWP) within the carrier can be increased, and the carriers in the carrier group can be configured with one or more BWPs.

[0037] Furthermore, based on the above application embodiment, each carrier is configured with a partial bandwidth, and the number of symbols of the partial bandwidth configured for each carrier is different. Carriers with partial bandwidths with the same number of symbols constitute the carrier group.

[0038] In one embodiment, each carrier may be configured with a partial bandwidth, and the number of symbols of the partial bandwidth may be different. Only carriers with the same number of symbols constitute a carrier group, that is, the number of symbols of the partial bandwidth configured for each carrier included in the carrier group is the same.

[0039] Furthermore, based on the above application embodiment, each carrier is configured with at least two partial bandwidths, the number of symbols of the partial bandwidths within each carrier or between the carriers is different, and carriers with partial bandwidths with the same number of symbols constitute a carrier group.

[0040] In an embodiment of the present application, each carrier can be configured with multiple partial bandwidths, the multiple partial bandwidths within a carrier can be different, or the multiple partial bandwidths between carriers can be different, and the number of symbols of the partial bandwidth configured for each carrier in each carrier group is guaranteed to be the same, that is, carriers with partial bandwidths with the same number of symbols constitute a carrier group.

[0041] Furthermore, based on the above-mentioned embodiment of the application, the same synchronization reference is used within the carrier group, and different references are used between the carrier groups.

[0042] In the embodiment of the present application, the same synchronization reference may be used within the determined carrier group, while different carrier groups may use different synchronization references.

[0043] In an exemplary embodiment, assuming that two carrier groups determine synchronization references for CG0 and CG1 respectively, the carriers within CG0 use the first synchronization reference, and the carriers within CG1 use the second synchronization parameter, that is, the carriers within the same carrier group use the same synchronization reference, while the carriers in different carrier groups can use different synchronization references.

[0044] Based on the above application embodiment, the synchronization reference comes from a synchronization source of a specific carrier or a synchronization source of a specific node.

[0045] FIG2 is a flowchart of another carrier aggregation method provided in an embodiment of the present application. Referring to FIG2 , the method provided in an embodiment of the present application includes the following steps.

[0046] Step 210: The first entity determines a carrier group and carriers included in the carrier group through configuration or pre-configuration.

[0047] Step 220: Ensure that the total power of each carrier group is less than or equal to the maximum transmission power of the terminal according to the first information, wherein the first information includes at least one of the following: carrier group priority, carrier priority, channel priority, service priority, priority indicated by side link control information, and pre-configured priority.

[0048] In an embodiment of the present application, the total power of each carrier group can be determined according to the first information, thereby ensuring that the total power of each carrier group is less than or equal to the maximum transmit power of the terminal, wherein the first information may include one or more of the carrier group priority, carrier priority, channel priority, service priority, priority indicated by the side link control information, and pre-configured priority. Among them, the channel priority includes the priority of PSSCH, PSSCH, PSFCH, and S-SSB, and the service priority includes the priority of unicast service, multicast service, and broadcast service.

[0049] Further, based on the above-mentioned application embodiment, the total power of each carrier group is greater than the maximum transmission power of the terminal, and at least one of the carrier group, carrier, channel, and service is discarded according to the first information.

[0050] In an embodiment of the present application, if the total power of the carrier group determined by the first information is greater than the maximum transmission power of the terminal, one or more of the carrier group, carrier, channel, and service are discarded according to the priority in the first information, thereby ensuring that the total power of the carrier group is less than or equal to the maximum transmission power of the terminal.

[0051] In an exemplary embodiment, the discarding process is illustrated by taking the carrier group priority as an example. For example, the priority of carrier group CG0 is higher than the priority of carrier group CG1. If the total power of multiple carrier groups is greater than the maximum transmission power of the terminal, the power is allocated to carrier group CG0 first, and the remaining power is allocated to the carriers within carrier group CG1. Alternatively, the carriers within CG1 do not transmit data, or the carriers within CG1 are discarded.

[0052] In another exemplary embodiment, the discarding process is illustrated by taking the PSSCH priority as an example. For example, the carriers of carrier group CG0 carry PSSCH0 and PSSCH1 respectively, and the carriers in carrier group CG1 carry PSSCH2 and PSSCH3 respectively, and the order of PSSCH priority from high to low is PSSCH0 higher than PSSCH2, PSSCH2 higher than PSSCH1, and PSSCH1 higher than PSSCH3. If the total power of multiple carrier groups is greater than the maximum transmit power of the terminal, the lower priority PSSCH is discarded until the total power of multiple carrier groups is less than or equal to the maximum transmit power of the terminal. That is, PSSCH3 can be discarded first, and it is determined whether the total power of carrier group CG0 and carrier group CG1 is less than or equal to the maximum transmit power of the terminal. If so, the discarding is stopped. If not, PSSCH1 is continued to be discarded, and it is determined again whether the total power of carrier group CG0 and carrier group CG1 is less than or equal to the maximum transmit power of the terminal. The above process can be repeated until the total power of carrier group CG0 and carrier group CG1 is less than or equal to the maximum transmit power of the terminal.

[0053] In another exemplary embodiment, the discarding process is explained by taking the carrier group priority and PSSCH priority as an example. For example, the carrier group priority of carrier group CG0 is higher than the carrier group priority of carrier group CG1. The carriers of carrier group CG0 carry PSSCH0 and PSSCH1 respectively. The carriers in carrier group CG1 carry PSSCH2 and PSSCH3 respectively. The order of PSSCH priority from high to low is PSSCH0 higher than PSSCH2, PSSCH2 higher than PSSCH1, and PSSCH1 higher than PSSCH3. If the total power of multiple carrier groups is greater than the maximum transmit power of the terminal, power is allocated to the carriers in CG0 first, the carriers in CG1 are lost, and the lower priority PSSCHs in CG0 are discarded until the total power of multiple carrier groups is less than or equal to the maximum transmit power of the terminal. It can be understood that when discarding at least one of the carrier group, carrier, channel, and service based on the first information, there can also be an application priority between the priorities such as the carrier group priority, carrier priority, channel priority, service priority, priority indicated by the side link control information, and pre-configured priority in the first information. For example, the carrier group priority is discarded over the PSSCH priority.

[0054] In some application embodiments, the method further includes: determining the feedback channel carrier through a carrier index or a cell index.

[0055] In the embodiment of the present application, the first entity may also determine the feedback channel carrier through a carrier index or a cell index, that is, determine the carrier of the feedback channel through the carrier index or the cell index.

[0056] In some other application embodiments, the method further includes: at least one of configuring or pre-configuring to enable or disable a feedback channel carrier function.

[0057] In the embodiments of the present application, the feedback channel carrier function is enabled or disabled by configuration or pre-configuration. For example, a binary value "0" corresponding to the feedback channel carrier function enable or disable signaling indicates enabling the feedback channel carrier function, while a binary value "1" indicates disabling the feedback channel carrier function. The enabling or disabling scope can be per carrier group, per frequency band, or per terminal.
