Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a method and a device that perform transmission in consideration of prioritization when multiple different types of uplink transmission in the same transmission time interval (TTI) are performed on a plurality of component carrier when user equipment (UE) is in a power restricted condition.

SOLUTION: In a terminal device power for uplink shared channel (PUSCH) transmission on a first component carrier belonging to a first timing advance group is determined for each sub-frame. If total transmission power exceeds a maximum transmission power value set for the terminal device the power for PUSCH transmission is adjusted so that transmission power after adjustment does not exceed the maximum transmission power value in a part where the PUSCH transmission overlaps with random access channel (PRACH) transmission in a second sub-frame of the PRACH transmission on a second component carrier belonging to a second timing advance group.
