    摘要： A system including a first receiver module and a first interference canceller module. The first receiver module is configured to receive a first signal including a first set of codewords and to generate a first set of decoded codewords by decoding at least one of the first set of codewords. The first interference canceller module is configured to measure first reliability metrics of codewords corresponding to the first set of decoded codewords; based on the first reliability metrics, select a second set of decoded codewords from the first set; generate a second signal based on the second set of decoded codewords; and subtract at least a portion of the second signal from the first signal to cancel interference of codewords corresponding to the second set of decoded codewords on the second set of codewords in the first signal.

    摘要： In a method for utilizing beamforming in a wireless communication system, reference signals corresponding to a first communication channel from a first communication device to a second communication device are received, and an estimate of the first communication channel is generated using the received reference signals. One or more transmit beamforming vectors are calculated using the estimate of the first communication channel, and the one or more transmit beamforming vectors are utilized to transmit signals via a second communication channel from the second communication device to the first communication device while the first communication device assumes that the first second communication device is not utilizing beamforming.

    摘要： In a method for transmitting control signals in a multicast communication system, wherein the multicast communication system broadcasts one or more multicast channels, one or more occurrences of a first control signal are transmitted. The first control signal includes at least control information corresponding to the one or more multicast channels. Additionally, one or more occurrences of a second control signal are transmitted for each of the one or more multicast channels. The second control signal includes at least control information corresponding to the respective multicast channel. At least one transmission of an occurrence of the second control signal is synchronized with at least one transmission of an occurrence of the first control signal.
