Abstract: A hybrid multi-mode mobile station makes a decision either to encode and modulate a new user data packet using the same OFDMA or pre-coded CDMA mode used for the last retransmission of a previous packet or to switch modes based on inputs of a measured average transmission power of the previous packet and a Signal-to-interference plus Noise Ratio (SINR) as determined from measurements made by the base station and either directly reported to the mobile station or calculated by the mobile station from measurements made by the base station that are reported back to the mobile station.

Abstract: A mobile terminal is controlled via over-the-air feedback so as to enable its data transmissions to be independently and successfully decoded at each of the base stations in its active set absent a transmit power limitation or data retransmission limit. Using the decoded data, the channel is re-estimated and the waveform received from the mobile terminal is reconstructed and subtracted from the total interference at each base station in the active set where decoding has been successful. As a result, transmissions from other mobile terminals, which have yet to be successfully decoded at such a base station, will experience a higher signal-to-noise ratio and thus an increased likelihood of being successfully decoded.

Abstract: A closed loop power control based on receiving .a continuous quality feedback is described. A main reverse link (RL) pilot is controlled by the quality feedback of a substantially continuous delay sensitive traffic stream, such as Voice-over-IP (VoIP), when such a stream is enabled. When such a stream is not enabled, the quality of a continuous RL overhead channel is used to control the pilot power. At the same time, the Traffic-to-Pilot Ratios (TPR) of contemporaneously transmitted delay sensitive data streams are independently adjusted based on a quality feedback associated with each such data stream.
