Abstract
Methods and systems for communicating on a wireless channel are provided which enable subscribers that share the channel to transmit using different modulation schemes. The modulation scheme used by each subscriber is assigned to the subscriber by a wireless access termination system. The modulation scheme assigned to a subscriber by the wireless access termination system is determined based on measurements of the quality of signals received from that subscriber. In one embodiment, the invention includes a transmitter and a receiver. The receiver is capable of transmitting data using one of a number of encoding and symbol constellation configurations. The receiver is also capable of receiving a first signal. Receiving the first signal causes the transmitter to transmit a second signal using a specified encoding and symbol constellation configuration.
