Abstract:
This application discloses a precoding information sending solution and a precoding information feedback solution. A base station generates a signaling indicator and sends the signaling indicator to user equipment. The signaling indicator indicates related information about a precoding matrix set determined by the base station from a stored codebook, where the precoding matrix set belongs to a subset of the stored codebook. The user equipment selects a precoding matrix according to the signaling indicator sent by the base station, and sends a precoding matrix indicator PMI to the base station. The precoding matrix is selected according to a precoding matrix set and a feedback is performed. Therefore, complexity of searching for the precoding matrix and precoding feedback bits may be reduced.

Claim (Index 9):
An apparatus, comprising:\n a memory and at least one processor coupled to the memory, the at least one processor being configured to obtain a signaling indicator from a base station, the signaling indicator indicating one or more pieces of the following information:\n (i) a set of W 2  codewords in a precoding matrix set, wherein the set of W 2  codewords in the precoding matrix set is a subset of W 2  codewords in at least one codebook; \n (ii) a set of second precoding matrix i 2  indicators in a precoding matrix set, wherein the set of i 2  indicators is a subset of i 2  indicators in at least one codebook, and each value of i 2  indicators corresponds to a W 2  codeword; \n (ii) a set of W 1  codewords in a precoding matrix set, wherein the set of W 1  codewords in the precoding matrix set is a subset of W 1  codewords in at least one codebook; or \n (iv) a set of first precoding matrix i 1  lindicators in the precoding matrix set, wherein the set of i 1  indicators is a subset of i 1  indicators in at least one codebook, and each value of i 1  indicators corresponds to a W 1  codeword; and \n select a precoding matrix based on the signaling indicator, wherein the selected precoding matrix belongs to the precoding matrix set.
