摘要： Systems and methodologies are described that facilitate integrating a list-sphere decoding design in a multiple input-multiple output (MIMO wireless communication environment. According to various aspects, optimal rank selection and CQI computation for an optimal rank can be performed in conjunction with a non-linear receiver, such as a maximum life (ML) MMSE receiver, a non-linear receiver with a list-sphere decoder, and the like. Optimal rank selection can be performed using a maximum rank selection protocol, a channel capacity-based protocol, or any other suitable protocol that facilitates rank selection, and CQI information can be generated based in part on effective SNRs determined with regard to a selected optimal rank.

摘要： Aspects describe controlling a power level for an access terminal in a wireless communication system that utilizes multiple modulation waveforms. The power can be controlled after an Access Grant is received in response to an Access Probe until the mobile device transitions into a steady state. A reference power can be continuously monitored and a setting of a power amplifier can be modified only when the reference power changes. A digital gain of a reverse data channel can be adjusted relative to the reference power level.

摘要： Systems and methodologies are described that facilitate performing interference nulling and rank prediction in an access terminal. Multiple receiver demodulator types may be implemented at the access terminal, and an interference covariance matrix may be estimated thereat. SNRs may be calculated for the various receiver demodulator types, and an optimum rank and associated CQI information may be identified and generated, respectively, which information may then be transmitted to an access point. At least one of the receiver demodulator types may perform an interference nulling protocol. For example, the receiver demodulator types may comprise at least one minimum mean-squared error interference-nulling (MMSE-IN) demodulator, along with and one or more of a maximal ratio combining (MRC) demodulator and a minimum mean-squared error (MMSE) demodulator.

摘要： Methods and apparatuses are proposed for supporting one or more user-dependent channel state information (CSI) feedback rates in a downlink spatial division multiple access (SDMA) system. For certain aspects, an access point (AP) may receive a channel evolution feedback from one or more stations and send a request for CSI to the stations whose CSI values need to be updated. For certain aspects, the AP may poll the stations for updated CSI values. For certain aspects, deterministic back-off timers may be assigned to the stations indicating when to send their CSI feedback. The proposed methods may improve system performance.
