摘要： A method and an apparatus in a wireless communication system are provided. Configuration information is received on resource pools in multiple carriers for a vehicle to everything (V2X) sidelink communication, At least one carrier is selected for transmission among the multiple carriers. An order of the at least one carrier is determined according to a decreasing order based on a highest priority of a sidelink traffic channel. A set of candidate resources associated with each of the at least one carrier is determined according to the determined order. A candidate resource is excluded from the set of candidate resources, in case that the candidate resource is not supported due to a limitation of a user equipment (UE) in supported carrier combinations.

The present disclosure provides a power allocating method. A User Equipment (UE) receives power control indication information from a control node, obtains a power control mode, and/or, uplink transmission power configuration information. The UE allocates power for each uplink carrier, based on the power control mode, and/or, the uplink transmission power configuration information. By applying the present disclosure, power waste generated in the following scene may be reduced. A scheduled uplink signal cannot be transmitted in a corresponding carrier due to a busy channel.
