摘要： A method and apparatus for feeding back channel information from a first device to a second device in a wireless communication system are provided. The first device estimates channel parameters based on a signal received from the second device, and determines a set of angle parameters indicative of an angle representation of a V matrix, which is the right singular matrix of a singular value decomposition of an estimated channel matrix H. The angle parameters can be derived according to a Givens rotation method or Cosine-Sine decomposition. The first device applies a Trellis Coded Quantization (TCQ) scheme to map the angle parameters to a trellis. A Viterbi algorithm applied to the trellis generates quantized angle parameters which are transmitted to the second device.

摘要： A method and apparatus for controlling signal transmission is provided. The method includes determining whether a signal to noise ratio (SNR) between a first base station and a signal receiving node is less than a threshold, and controlling the first base station and a second base station to cooperatively transmit a signal to the signal receiving node in response to the SNR being less than the threshold. Further, the second base station is located in an adjacent cell to a cell containing the first base station.
