1. A method at a mobile station in a wireless communication system that is in communication with a base station, the method comprising:
operating an uplink for transmitting new user data in either a first or second predetermined encoding and modulation mode as determined in response to a measured average transmission power of the mobile station for previous user data and a Signal-to-Interference plus Noise Ratio (SINR) as measured at the base station and reported to the mobile station or as calculated by the mobile station from measurements made by the base station that are reported to the mobile station, wherein the Peak-to-Average Power Ratio (PAPR) of the first and second encoding and modulation modes are different.
