Abstract:
Provided are a method and device for uplink information feedback and downlink data transmission, used, when the speed of motion of a terminal is high, for solving the problem of CSI information reported by the terminal being insufficient to track changes on the channel, such that data transmission carried out on the basis of the channel state information reported by the terminal causes seriously degraded performance. The method comprises: a base station obtaining a precoding matrix of a terminal, and an l-th precoding matrix set of L precoding matrix sets corresponding to said precoding matrix; each precoding matrix set of said L precoding matrix sets containing at least one precoding matrix; said at least one precoding matrix originating from a preset codebook, wherein l≤L and L is a positive integer; according to the precoding matrix contained in the obtained l-th precoding matrix set, the base station sending downlink data to the terminal. By means of the precoding matrix set, a relatively wide beam is formed to cover the user, thus guaranteeing downlink transmission for the terminal when it is moving at high speed, improving the reliability of downlink transmission.

Claim (Index 13):
A base station, comprising a processor, a memory, a receiver and a transmitter, wherein the memory is configured to store programs, and the processor is configured to read the programs in the memory to execute:\n obtaining a pre-coding matrix of a UE, and an l-th level of group of pre-coding matrixes among L groups of pre-coding matrixes corresponding to the pre-coding matrix, wherein each of the L groups of pre-coding matrixes comprises at least one pre-coding matrix from a preset codebook, l\u2264L, and L is a positive integer; and transmitting downlink data to the UE through the transmitter according to the pre-coding matrixes in the l-th level of group of pre-coding matrixes.
