UPLINK TRANSMISSION POWER CONTROL IN WIRELESS COMMUNICATION SYSTEM

摘要

A method of controlling uplink transmission power to reduce interference in a wireless communication system comprises establishing an uplink communication through an uplink dedicated channel between a user equipment and a base station, wherein the base station is operationally connected to a radio network controller. The method also comprises receiving a scheduling command from the base station for controlling transmission power of the user equipment, wherein the scheduling command is determined from scheduling information comprising transmission power information received from the radio network controller, the transmission power information being determined in response to information associated with at least one user equipment that is in soft handover relationship with another base station. The method also comprises controlling uplink data transmission in response to the scheduling command.
