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 9):
The base station of  claim 8 , wherein the instructions further cause the processor to:\n receive a second precoding mode transmitted by an adjacent cell, wherein the second precoding mode records information of a precoding matrix used by the adjacent cell on each resource; the instructions cause the processor to select the scheduling user further cause the processor to: determine, with respect to each resource, candidate users configured on the resource and a first precoding matrix configured for each of the candidate users according to the first precoding mode, and determine a second precoding matrix used by the adjacent cell on the resource according to the second precoding mode; calculate a throughput of each of the candidate users on the resource according to the first precoding matrix and the second precoding matrix; and determine a candidate user with a maximum throughput as the scheduling user on the resource.
