Title: METHOD FOR TRANSMISSION DIVERSITY, TERMINAL AND BASE STATION
Abstract:
The present invention provides a method and apparatus for information feedback. The method comprises: receiving signalling sent by a base station, the signalling being used for instructing to feed back transmission diversity based channel status information; sending the feedback information to the base station, the feedback information comprising a pre-coding matrix indicator (PMI), wherein the PMI is used for indicating a pre-coding matrix in a set of pre-coding matrices, and the structure of the pre-coding matrix is one of two specific structures. According to the feedback method and apparatus of the present invention, the problem that a wave beam is blocked can be effectively avoided, improving the performance of transmission.
