Abstract: A wireless communication apparatus comprises a processor configured to decode signals that are received over two or more subcarriers of a segment of subcarriers, which is one of a plurality of segments of subcarriers available for communication, and to provide precoding information for at least one segment; and a transmitter configured to transmit the precoding information, wherein the transmitter is configured to transmit the precoding information on a feedback channel associated with the at least one segment. The precoding feedback is reported in multiple channel quality indication (CQI) channels and the number of used CQI channels depends on the number of available codes.

Abstract: A technique for performing AGC and DC compensation in a receiver. The receiver comprises an energy estimator for generating an estimate of the level of a received signal; an RF device to apply gain to the received signal; an AGC for controlling the RF device gain based on the energy estimation; a first DC compensation loop for finely adjusting the DC component of the received signal in fast or slow tracking mode (FTM or STM); and a second DC compensation loop for coarsely adjusting the DC component of the received signal. Three modes of AGC operations: In Acquisition, iterations of FTM fine DC adjustment, short energy estimation, and RF device gain adjustment are performed during signal timing detection. In Connected, long energy estimation, RF device gain adjustment, and STM fine and coarse DC adjustments are performed during superframe preamble. In Sleep, FTM fine DC adjustment, short energy estimation, and RF device gain adjustment are performed during superframe preamble.

Abstract: Systems and methodologies are described that facilitates computing a precoding index which correlates to a precoding matrix within a codebook. According to various aspects, systems and/or methods are described that facilitate computing an effective signal-to-noise ratio (SNR). Such systems and/or methods may further facilitate selecting a precoding matrix and a corresponding precoding index. Such systems and/or methods may still further facilitate employing the precoding matrix in a MIMO wireless communication system.

Abstract: Techniques to enhance the performance in a wireless communication system using segments called subbands and using precoding are shown. According to one aspect, the bandwidth for transmission to an access terminal is constrained to a preferred bandwidth which is less than the bandwidth available for transmission to an access terminal and precoding information related to the subcarriers within the constrained bandwidth is provided to a transmitter. The precoding information related to the subcarriers within a constrained bandwidth provides feedback about the forward link channel properties relative to different subbands and may be fed back on a channel associated with the bandwidth.
