摘要：Packet transmissions between a base station and terminals are performed usinghalf-duplex uplink and downlink transmission intervals with adaptive intra-interval packetretransmission and packet expansion. The uplink and downlink transmission intervalsused for communication with a terminal may be offset commensurate with a degree ofsymmetry of information flow between the terminal and the base station. The offsetbetween the uplink and downlink transmission intervals may be adaptively adjustedbased on a type of information being communicated between terminals and the basestation. For example, different offsets may be used for voice and data communications. Insome embodiments of the present invention, uplink and downlink transmission intervalsfor communications with a terminal have substantially equal durations. For example, voicepacket transmissions between the base station and the terminal may use uplink anddownlink transmission intervals having substantially equal durations.
