摘要：
A terminal apparatus increments a transmit counter based on a failure of random access response reception or contention resolution, and receives information for indicating a higher layer parameter powerRampingStep(1) and information for indicating a higher layer parameter powerRampingStep(2). A transmit power for PRACH transmission in a first step of a 2 step contention based random access procedure is given based at least on the transmission counter and the higher layer parameter powerRampingStep(1), and a transmit power for PUSCH transmission in the first step of the 2 step contention based random access procedure is given based at least on the transmission counter and the higher layer parameter powerRampingStep(2).
