1. A resource selection method, comprising:
initiating a first set of sidelink processes on a first set of carriers comprising at least one carrier, wherein the first set of sidelink processes comprises a plurality of sidelink processes;
triggering, in response to satisfying a trigger condition for a resource selection of one sidelink process of the first set of sidelink processes, a carrier selection to obtain a selected second set of carriers, wherein the second set of carriers is selected based on channel busy ratio of each candidate carrier;
initiating a second set of sidelink processes on the selected second set of carriers; and
triggering, according to a preset rule, resource selection of the second set of sidelink processes, comprising:
based on a determination that the carrier selection corresponding to the first set of sidelink processes is performed, triggering the resource selection of the second set of sidelink processes on the selected second set of carriers, comprising:
when the selected second set of carriers is not the same as the first set of carriers, triggering the second set of sidelink processes to select new resources on the selected second set of carriers for data transmission; and
when the selected second set of carriers is the same as the first set of carriers, triggering the second set of sidelink processes to select new resources on the selected second set of carriers for data transmission.
