Abstract:
1. A method for controlling uplink transmission power in a wireless communication system comprising the steps of: aggregating at least one of a plurality of downlink carriers and a plurality of uplink carriers and mapping the plurality of downlink carriers and the plurality of uplink carriers between a User Equipment (UE) and a network in the wireless communication system; receiving a message relating to uplink carrier transmission power at the UE from the network via a downlink carrier; detecting a need to perform an uplink transmission through at least one uplink carrier; identifying a reference downlink carrier of the at least one uplink carrier from uplink carrier information in the message; determining a value of a variable of the at least one uplink carrier using a path loss of the identified reference downlink carrier; and determining uplink transmission power of the at least one uplink carrier in accordance with the value of the variable.
