摘要： Error protection based on a nonlinear code set may be used in a multiple input multiple output (MIMO) radio communications system. A decoder decodes received MIMO data streams and generates an automatic repeat request (ARQ) message for data units received for the MIMO data streams for each transmission time interval. An encoder codes the ARQ message using a code word from a nonlinear code set. At the data transmitter, which transmits one or more data units in transmission time intervals from two or more MIMO data streams, the ARQ message associated with the transmitted data units is decoded using a code word from the nonlinear code set.

摘要： A method and apparatus that reduces the likelihood of having a high peak power in any one bit position of code multiplexed downlink control channel symbols is described herein. An exemplary method includes selecting a different bit-level spreading sequence for each mobile terminal from a set of orthogonal bit-level spreading sequences, where code values in any one bit position are not the same for all of the bit-level spreading sequences in the set. When a code multiplexing system uses the selected bit-level spreading sequences from the sequence set to code multiplex the downlink control channel symbols, the resulting combined signal has a lower likelihood of having a high peak power.

摘要： A wireless communication receiver improves signal impairment correlation estimation in MIMO/MISO systems by considering different transmit power allocations and different transmit antenna power distributions in its impairment correlation calculations. The receiver may be implemented in according to a variety of architectures, including, but not limited to, Successive Interference Cancellation (SIC) Generalized RAKE (G-RAKE), Joint Detection (JD) G-RAKE, and Minimum Mean Squared Error (MMSE) G-RAKE. Regardless of the particular receiver architecture adopted, the improved impairment correlations may be used to calculate improved (RAKE) signal combining weights and/or improve channel quality estimates for reporting by receivers operating in Wideband CDMA (W-CDMA) systems transmitting HSDPA channels via MIMO or MISO transmitters. A transmitter may be configured to facilitate impairment correlation determinations by wireless communication receivers operating in MIMO/MISO environments, by signaling one or more values, e.g., data-to-pilot signal transmit power ratios and/or transmit antenna power distributions for the data and pilot signals.

摘要： A receiver includes a receiver circuit that decodes multiple signals of interest contained in a composite received signal. The receiver comprises a plurality of successive signal detection stages to detect respective signals contained in the composite received signal. Each detection circuit comprises at least one Generalized RAKE combining circuit and generates a detected signal at an output. Each but the last stage further comprises a signal regeneration circuit that cancels the signal of interest detected by that stage from a stage input signal provided to the next stage such that successive detection of the signals of interest benefits from cumulative cancellation of the previously detected signals.

摘要： A method, system, and apparatus for transferring new information on a dedicated physical channel (DPCH) from a base station to a user equipment (UE) terminal in a radio telecommunication system. A downlink signal containing the information, such as an ACK/NACK signal, is bit-level spread across one or more time slots utilizing a spreading sequence having good auto-correlation and cross-correlation properties with the DPCH. The spread downlink signal is then combined with a DPCH signal to form a combined signal, and the combined signal is spread utilizing a channelization code already assigned to the DPCH. The spread, combined signal is then transmitted to the UE terminal, which separately decodes the downlink signal to extract the information. The UE terminal then determines effects that the downlink signal had on the received DPCH signal, and subtracts the contribution of the downlink signal from the DPCH signal prior to decoding the DPCH signal.

摘要： A wireless communication receiver receiving a multiplexed signal comprising two or more signal streams calculates a received signal quality for the multiplexed signal as a function of stream-specific received signal qualities, determines one or more loss parameters indicative of variations in the stream-specific received signal qualities, and generates quality feedback based on such information. In turn, a transmitter controls the selection of one or more transmission parameters of the multiplexed signal based on the quality feedback, such that its transmit link adaptations account for the losses in received signal quality at the receiver arising from the variations in the stream-specific received signal qualities. The quality feedback may include calculated loss values, or parameter/penalties that permit loss calculation, and the method applies to both code multiplexing and spatial multiplexing.
