摘要： 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.

摘要： Systems and methodologies are described that facilitate estimating transmit covariance from evaluation of a channel (e.g., forward link channel, reverse link channel, . . . ) to be utilized in linear precoding for multiple-input multiple-output (MIMO) wireless communication systems. Predefined codebooks that include any number of precoding matrices may be modified based upon transmit covariance estimations to yield improved precoding performance. Further, channel related feedback may be generated and analyzed by utilizing the modified codebooks.

摘要： 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.

摘要： 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.

摘要： Embodiments are described in connection with enhancing performance in a wireless communication system using codebook technology. According to an embodiment is a method for enhancing performance in a wireless communication environment. The method can include receiving a user preference for a transmission mode, associating the user preference with an entry or entries in a codebook, and assigning the user to a transmission mode corresponding to the entry or entries. The transmission mode can be one of a precoding, space division multiple access (SDMA), SDMA precoding, multiple input multiple output (MIMO), MIMO precoding, MEVIO- SDMA and a diversity. Each entry can correspond to a transmission mode.
