    摘要： Techniques of selective demodulation of downlink frames using a subscriber description segment or activity descriptor to identify one or more subscriber stations to which at least a portion of data placed in the downlink frame is addressed in wireless communication systems such as frame-based point-to-multipoint wireless communication systems. The described techniques can be used to reduce power consumption at each subscriber station and to elongate the battery time of mobile devices, especially in the bursty Internet data transmission. The subscriber station can use information in the subscriber description segment or activity descriptor to decide whether to turn off receiver power for the remainder of a received downlink frame.

    摘要： Wireless communication techniques for cellular deployment of wireless communication systems with transmitters in each cell to have partially overlapped transmission patterns between two adjacent transmitters. Implementations of the described techniques can provide transmit diversity with intentional partial beam pattern overlays to improve cell sectorization or frequency re-use factor, at the same time, reduce intra-cell and inter-cell interference. Various modulations may be used in the described systems, including FDMA, TDMA, and OFDMA modulation schemes.

    摘要： Techniques for acknowledging message reception in a wireless OFDM/OFDMA system in clue receiving an unsolicited MAC management message at a subscriber station, operating the subscriber station to generate an acknowledgement (ACK) signal when the subscriber station receives the message from a base station, providing a pre-allocated uplink resource for the subscriber station to transmit the ACK signal to the base station without making a request to the base station for sending the ACK signal and sending the ACK signal consisting of a MAC header transmitted at the pre-allocated uplink source.
