Abstract

The invention provides a channel information feedback and resource configuration method and device, a base station and user equipment, so as to solve a problem that the effective utilization of MU-MIMO is not facilitated because a conventional channel state information feedback method cannot meet the MU-MIMO (multi-user multi-input multi-output) demands. The method comprises the steps: obtaining a first measurement resource and a second measurement resource, which are configured by the base station for the user equipment, wherein the first measurement resource is used for obtaining the channel information of the user equipment, and the second measurement resource is used for obtaining first interference information of paired user equipment, which is located in the same cell with the user equipment and carries out the pairing with the user equipment for multi-user transmission, for the user equipment, and also used for obtaining second interference information for the cell where the user equipment is located from other cells, and the second measurement resource of the user equipment is the first measurement resource of the paired user equipment; obtaining the channel quality index information of the user equipment according to the first and second measurement resources, and feeding back the channel quality index information to the base station.

Description

technical field [0001] The present invention relates to the technical field of communication applications, in particular to a channel information feedback, resource allocation method, device, base station and user equipment. Background technique [0002] EB / FD MIMO (Multiple-Input Multiple-Output, MIMO) is an important technology in the application of Release13. By using a large-scale two-dimensional antenna array at the base station, it can better support multi-user MIMO (Multiple-Input Multiple-Output) -User Multiple-Input Multiple-Output, MU-MIMO) transmission, which greatly improves the system capacity. However, in the current Long Term Evolution (LTE) / LTE-A standard, the channel state information (ChannelState Information, CSI) fed back by the user equipment (User Experience, UE) is based on the base station eNB using single user multiple input multiple output (Single-User Multiple-Input Multiple-Output, SU-MIMO) transmission. Therefore, if the eNB schedules multiple ...
