Abstract
A method and apparatus are provided for signaling a maximum UE transmitter power to a Node B for use in scheduling of uplink packet transmission in a mobile communication system. The Node B receives uplink channel status information from a UE and a maximum UE transmitter power from an RNC. The maximum UE transmitter power is the lower of the maximum allowed UL Tx power and the maximum Tx power of the UE. The Node B then schedules uplink packet transmission from the UE based on the uplink channel status information and the maximum UE transmitter power.
