METHOD AND SYSTEM FOR PRECODING DATA |
摘要 |
The present disclosure relates to channel state feedback in a communication system. The method includes obtaining a reference signal from an access point; deriving a rank indication, a codebook subset selection indication and a precoding matrix index based on the obtained reference signal; sending a first feedback message conveying the rank indication and the codebook subset selection indication, and sending a second feedback message conveying the precoding matrix index, to the access point; and receiving, from the access point, data precoded by a matrix derived based on the rank indication, the codebook subset selection indication and the precoding matrix index. |

1. A machine-readable storage medium having stored thereon, a computer program comprising at least one code section for distributing data, the at least one code section being executable by a machine for causing the machine to perform the following:
receiving at least one reference signal from a transmitting device; deriving a rank indication, a codebook index n1 in a first codebook C1, and codebook indices k1 and k2 in a second codebook C2 based on the at least one reference signal; sending the rank indication, the codebook index n1 in the first codebook C1, and the codebook indices k1 and k2 in the second codebook C2 to the transmitting device; and receiving data precoded by a first precoder from the transmitting device; wherein the first precoder comprises a second precoder and a third precoder, the second precoder is determined based on the indices n1 and k1, and the third precoder is determined based on the indices n1 and k2. |
