摘要： Techniques are provided to support successive interference cancellation (SIC) receiver processing with selection diversity whereby each of NT transmit antennas may be turned on or off. One symbol stream may be transmitted from each transmit antenna. A SIC receiver recovers the transmitted symbol streams in a specific order. Up to N T ! orderings are evaluated. For each ordering, N T post-detection SNRs are obtained for N T transmit antennas and used to determine N T data rates, where the data rate is zero if the post-detection SNR is worse than a minimum required SNR. An overall data rate is computed for each ordering based on the N T data rates. The ordering with the highest overall data rate is selected for use. Up to N T symbol streams arc processed at the data rates for the selected ordering and transmitted. The transmitted symbol streams are recovered in accordance with the selected ordering.

摘要： A rate adaptive transmission scheme for MIMO systems, which can transmit a variable number of data symbol streams, provide transmit diversity for each data symbol stream, and fully utilize the total transmit power of the system and the full power of each antenna. In one method, at least one data symbol stream is received for transmission from a plurality of antennas. Each data symbol stream is scaled with a respective weight corresponding to the amount of transmit power allocated to that stream. The scaled data symbol stream(s) are multiplied with a transmit basis matrix to provide a plurality of transmit symbol streams for the plurality of antennas.; The transmit basis matrix (e.g., a Walsh-Hadamard matrix or a DFT matrix) is defined such that each data symbol stream is transmitted from all antennas and each transmit symbol stream is transmitted at (or near) the full power for the associated antenna.

M groups of R sets are formed for the R times M sets, and M groups of T sets are formed for the T times M sets, wherein one coefficient in the T by M matrix is used to generate each set of P scaled pilot symbols, and wherein each group of T sets of P scaled pilot symbols is transmitted from T transmit antennas on P subbands; deriving an initial frequency-domain frequency response estimate for each set of P received pilot symbols, wherein R times M initial frequency response estimates are derived for the R times M sets of P received pilot symbols; deriving an initial time- domain impulse response estimate for each initial frequency response estimate, wherein R times M initial impulse response estimates are derived for the R times M initial frequency response estimates; deriving R times T final time-domain impulse response estimates based on the R times M initial impulse response estimates and the T by M matrix; and, deriving a final frequency-domain frequency response estimate for each final impulse response estimate, wherein R times T final frequency response estimates are derived for the R times T final impulse response estimates and represent an estimate of a multiple- input multiple-output (MIMO) channel between the T transmit antennas and the R receive antennas.

摘要： Techniques for controlling transmit power of a terminal are described. The terminal may send a first transmission (e.g., for pilot or signaling) on the reverse link, receive feedback (e.g., a power control command or an erasure indicator) for the first transmission, and adjust a reference power level based on the feedback. The terminal may also receive interference information and possibly other parameters such as a pilot quality indicator (PQI), an offset factor, and a boost factor from a sector. The terminal may determine transmit power for a second transmission to the sector based on the interference information, the reference power level, and/or the other parameters. The terminal may receive the feedback from one sector and may send the second transmission with CDMA or OFDMA to the same sector or a different sector.
