Abstract:
1. A method for determining a codebook generation mode, comprising: selecting, by a transmitter, a codebook generation mode for a set of rank of a user equipment (UE) from at least two preset codebook generation modes, wherein the set of rank of the UE is any one set of Z sets of rank, and the Z sets of rank are grouped from M kinds of ranks among N kinds of ranks supported by the UE, where N, M, Z are integers greater than or equal to 1, M is less than or equal to N, and Z is less than or equal to M; and sending, by the transmitter, the selected codebook generation mode to the UE or a serving cell of the UE; wherein the sending, by the transmitter, the selected codebook generation mode comprises: informing the UE of the selected codebook generation mode when the selection is performed by the serving cell and Z is equal to 1; informing the UE of the selected codebook generation mode and a corresponding rank when the selection is performed by the serving cell and Z is greater than 1; informing the serving cell of the selected codebook generation mode when the selection is performed by the UE and Z is equal to 1; and informing the serving cell of the selected codebook generation mode and a corresponding rank when the selection is performed by the UE and Z is greater than 1, or informing the serving cell of a used rank determined by the UE and a corresponding codebook generation mode when the selection is performed by the UE and Z is greater than 1.
