Abstract
A method and apparatus for transport format selection in a mobile wireless communication device. During a simultaneous voice and data call, the mobile wireless communication device selects a transport format for proper uplink data transmission. Simultaneous voice and data calls require higher uplink transmit power than voice only calls. The mobile wireless communication device selects a transport format based on the uplink transmit power level. At higher transmit power levels, minimum or zero data rates are chosen to maintain sufficient power for simultaneous voice. Transmit format is specified using a transmit format combination indicator.
