Abstract

The present invention discloses a data transmission method. The method comprises that a base station (eNB) calculates positional information of a terminal (UE) according to channel information of the UE; matching of the UE is carried out according to the positional information obtained through calcuation; according to a matching result, resource scheduling is carried out and pre-coding vectors of the UE is calculated; and carrying out data transmission according to the scheduled resources and the pre-coding vectors acquired through calculation. A base station is also disclosed.

Description

technical field [0001] The invention relates to data transmission technology of a communication system, in particular to a data transmission method and a base station. Background technique [0002] Coordinated Multi-Point transmission / reception (CoMP) technology, when applied to an Advanced Long Term Evolution (LTE-Advanced) system, can provide high-speed data coverage and increase cell throughput. At the same time, since the precoding technology in the CoMP system can realize beamforming and interference suppression to the system, the interference in the CoMP system can be suppressed by selecting an appropriate precoding matrix, thereby improving the spectral efficiency of the system and the throughput of edge users Rate. [0003] In the three-dimensional (3Division, 3D) LTE system, the base station uses a multi-antenna array for data transmission, and more antennas can improve the performance of the LTE-Advanced system to a greater extent; the 3D dual-beam LTE system prov...
