摘要： Techniques are provided for transmitting and receiving a mother code in an incremental redundancy hybrid automatic repeat request protocol. A set of information bits corresponding to a message may be encoded and interleaved to produce the mother code. Each bit position of the mother code may be mapped to an output symbol, and each output symbol may be mapped to an antenna for transmission. One or more transmissions of symbols contained in the output symbols may be performed, where each transmission may include puncturing the mother code by selecting one or more symbols from the of output symbols, and transmitting each symbol in the one or more symbols on an antenna corresponding to that symbol. The mother code may be decoded, in part, by determining combinable bits contained within a set of received symbols, and computing one or more log likelihood ratio values corresponding to each symbol in the set of received symbols.

摘要： Systems and methods are provided for transmitting information between an intended source and a receiver to minimize co-channel interference from at least one intefering source. Pilot subcarriers and data subcarriers may be broadcast from an intended source and at least one interfering source. The pilot subcarriers may be shared across base stations or distributed among base stations in frequency, in time, or both. In addition, the frequency reuse factor of the pilot subcarriers may be different than the frequency reuse factor of the data subcarriers. A receiver receives a composite signal that corresponds with an intended signal from an intended source and an interfering signal from at lease one interfering source. The portion of the received signal that corresponds to the intended signal may be recovered by the receiver based on the broadcast of the pilot subcarriers.

摘要： Systems and methods are provided for decoding signal vectors in multiple-input multiple-output (MIMO) systems, where the receiver has received one or more signal vectors based on the same transmitted vector. The symbols of the received signal vectors are combined, forming a combined received signal vector that may be treated as a single received signal vector. The combined received signal vector may be equalized by, for example, a zero-forcing or minimum-mean-squared error equalizer or another suitable linear equalizer. Following equalization, the equalized signal vector may be decoded using a simple, linear decoder.

The optimization technique is performed on the objective function over a range of candidate CQI values, and the selected value for the CQI is the candidate CQI value that optimizes the objective function.
