ABSTRACT:
A portable communication device (150, 170, 175, 200) is responsive to an uplink change to determine whether the uplink change is practicable (305, 405, 505). If the uplink change is determined by the device to be practicable, the uplink change will be permitted by the device. If the uplink change is determined by the device to not be practicable, alternatives are evaluated (320, 420, 520). A network (102) upon determining that a portable communication device (150, 170, 175, 200) requires an uplink power change, transmits (630) the power change request to the portable device. Responsive to the power change request, the network receives from the device a data allocation change (640) associated with said power change request. The network transmits an updated uplink channel allocation assignment if available.
