METHOD AND USER EQUIPMENT FOR CONTROLLING UPLINK TRANSMISSION POWER

摘要

Provided are a method and a User Equipment (UE) for controlling uplink transmission power the method includes: UE judges whether the adjacent subframes among multiple carriers transmit uplink channels at the same time; the adjacent subframes among multiple carriers are partly overlapped; the multiple carriers have different timing advance value; if the adjacent subframes among multiple carriers transmit uplink channels at the same time the user equipment will perform a processing for the uplink channels transmitted by the last symbol so the total transmission power of the uplink channels is below the maximal transmission power or interference level of the user equipment the last symbol is in the partly overlapped subframes of the carriers except the carrier has the maximal timing advance value. The embodiment of the present invention avails to avoid power restricted caused when the uplink transmission power of the UE exceeds the maximal transmission power of the UE or to avoid interference restricted caused when the uplink transmission power of the UE reaches the interference level and these are caused when the UE transmits uplink channels through the carriers having different Timing Advance Group (TAG) and the adjacent subframes among carriers having different TAG are partly overlapped.
