Abstract:
Disclosed are a downlink precoding method and a base station. The method includes: configuring a first precoding mode for a first cell, wherein the first precoding mode includes information of a precoding matrix configured for each candidate user of the first cell on each resource; selecting a scheduling user on each resource from candidate users according to the first precoding mode; and performing precoding to a channel estimation signal and downlink data of the scheduling user according to a precoding matrix of the scheduling user, and transmitting precoded channel estimation signal and precoded downlink data to the scheduling user. Such method and base station of the present disclosure can reduce the feedback overhead of the user, effectively improve the accuracy of channel quality indicator (CQI) estimation, and improve the system throughput and user throughput.

Claim (Index 13):
The base station of  claim 8 , wherein the instructions that cause the processor to configure the first precoding mode further cause the processor to: determine a statistical channel characteristic of each candidate user on each resource, configuring the precoding matrix for the candidate user according to the statistical channel characteristic, and record the information of the precoding matrix into the first precoding mode.
