Abstract

A method of performing uplink mobile communications may include identifying a first uplink data and a second uplink data, wherein the first uplink data has a higher transmission priority than the second uplink data, and evaluating a plurality of candidate uplink channels to generate a plurality of uplink channel quality measures. Each of the plurality of uplink channel quality measures may be associated with one of the plurality of candidate uplink channels. The method may further include performing a comparison between one or more of the plurality of uplink channel quality measures to select a first uplink channel from the plurality of candidate uplink channels, transmitting the first uplink data using the first uplink channel, and transmitting the second uplink data using a second uplink channel of the plurality of candidate uplink channels.
