A wireless communication device 102, 122 transmits a hierarchically modulated reverse link (RL) WWAN signal comprising a lower modulation order component and a higher modulation order component. In a first embodiment, an interface node 100 receives and demodulates the hierarchical modulated signal to recover the extended data sent with the higher modulation order component. The interface node sends extended data to a base station 105 that is unable to recover the higher modulation order component from the UE device. In another embodiment, the lower modulation order component corresponds to first service level data and the higher modulation order component corresponds to second service level data. The interface node 120 receives and demodulates the hierarchical modulated signal to recover second service level data, and sends the second service level data to a recipient. |
