1. A carrier aggregation parameter configuration method, applied to a first device, wherein the method comprises:
sending first information to a second device, wherein the first information is used to indicate a target carrier aggregation parameter configured for a sidelink service, and the sidelink service is a sidelink service between the first device and the second device;
wherein the sending first information to a second device comprises:
sending target information to the second device, the target information comprising the first information; wherein
in a case that the target information is layer 2 control signaling, after the sending target information to the second device, the method further comprises:
in a case that the target carrier aggregation parameter has changed, sending second control signaling to the second device, wherein the second control signaling comprises second information, the second information is used to indicate a reconfigured target carrier aggregation parameter, and the second control signaling is layer 2 control signaling; or
in a case that the target carrier aggregation parameter remains unchanged, periodically sending third control signaling to the second device, wherein the third control signaling comprises the first information, and the third control signaling is layer 2 control signaling;
wherein after the sending second control signaling to the second device, the method further comprises:
in a case that the target carrier aggregation parameter remains unchanged, periodically sending the second control signaling to the second device.
