摘要

A method for receiving channel state information (CSI) by a base station, includes transmitting configuration information indicating whether to use a 4 antenna ports codebook, wherein a first codebook index for a first precoding matrix indicator (PMI) and a second codebook index for a second PMI for a specific CSI report mode with 4 antenna ports are determined when the UE is configured to use the 4 antenna ports codebook; and receiving the CSI indicating the first codebook index and the second codebook index, wherein a value of the first codebook index is determined as follows: when a rank indicator (RI) is 1, the value of the first codebook index is determined based on a value of the first PMI multiplied by 4, and when the RI is 2, the value of the first codebook index is determined based on the value of the first PMI multiplied by 4.

說明書

[ e 4 e 2 e 2 - e 4 ]

With reference to FIG. 16, a channel state information reporting method will be described according to an embodiment of the present invention. With reference to FIG. 16, a channel state information reporting method according to an embodiment of the present invention will be described.

In operation S161, a UE subsamples a first codebook associated with a first precoding matrix indicator (PMI) and a second codebook associated with a second PMI according to a report submode for a 4 antenna port.

A detailed subsampling method is the same as the subsampling method described with regard to the second embodiment of the present invention and a detailed description thereof will be omitted.

In operation S163, the UE reports channel state information based on the susampled first codebook and second codebook.
