Abstract:
1. A method of controlling an uplink transmit power in a wireless communication, performed by a user equipment (UE), the method comprising: acquiring a resource allocation for uplink transmission from a base station (BS); determining a maximum power reduction (MPR) based on the resource allocation; adjusting a maximum output power by using the MPR; determining a transmit power of a uplink channel within the adjusted maximum output power; and transmitting an uplink data on the uplink channel, wherein the resource allocation comprises a number of contiguous resource blocks in a channel bandwidth and a starting index which is an index of a resource block with the lowest index among the contiguous resource blocks, and the channel bandwidth is divided into a first region, a second region and a third region, wherein the MPR is determined according to the number of the contiguous resource blocks in the first region and the third region, and the MPR is determined according to the starting index in the second region, wherein the MPR in the third region increases as the number of the contiguous resource blocks decreases.
