    摘要： A method and apparatus for communicating a message from a transmitting station to a remote receiving station by adaptively selecting a retransmission protocol from two or more retransmission protocols based on at least one changing transmission variable is described herein. The transmitting station transmits a first version of the message in a first transmission. When the previous transmission was unsuccessful, a controller adaptively selects either the first version of the message or a second version of the message in accordance with the selected protocol.

    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： Estimating an error rate for received communications can include iteratively processing each of a plurality of received symbol sequences to provide a respective plurality of data sequences, and providing a number of iterations performed to provide each of the plurality of data sequences. An error rate for the received communications can then be estimated based on the number of iterations performed to provide each of the plurality of data sequences. Related receivers and communications devices are also discussed.

    摘要： Systems and methods for providing bandwidth adaptive reference signals are disclosed. In one embodiment, a wireless device receives a downlink signal from a base station in a cellular communication network on a corresponding downlink carrier, where a number of time domain units per frame in the downlink signal that carry reference symbols is determined based on, or is otherwise a function of, a system bandwidth of the downlink carrier. In addition, in some embodiments, a number of frequency domain units that carry reference symbols is also a function of the system bandwidth of the downlink carrier. The wireless device processes the reference symbols to provide one or more desired features such as, for example, synchronization, radio resource management measurements, channel estimation, or the like.

    摘要： Improvements in the performance of HARQ operation are achieved by considering two channel coding parameters, the number of filler bits F and the number of dummy bits ND, in the selection of the retransmission settings for HARQ operation. In one exemplary embodiment, an optimal RV setting for the retransmission is selected based on the number of filler bits F and the number of dummy bits ND. In another exemplary embodiment, an address offset to the RV starting point for a selected RV setting is selected based on the number of filler bits F and the number of dummy bits ND.
