Problems solved by technology

Therefore, the CQI collected by the base station from each UE cannot reflect the interference caused by other UEs to the UE in the real MU-MIMO state, so that the base station cannot know the actual channel state in the MU-MIMO state
Therefore, in the existing MU-MIMO system, it is difficult for the base station to perform accurate MU-MIMO scheduling

Abstract

The invention relates to electronic equipment and a communication method. The electronic equipment applied to a first terminal equipment side of a wireless communication system comprises a storage used for storing computer commands; and a processing circuit configured to execute the stored computer command to measure a firstly pre-coded first reference signal from a base station, wherein a first pre-coding matrix used for performing first pre-coding is determined by the base station according to respective channel state fed back by multiple pieces of candidate terminal equipment, and the multiple pieces of candidate terminal equipment comprise first terminal equipment; to determine the interference of the other terminal equipment in the multiple pieces of candidate terminal equipment to the first terminal equipment; and to feed back information that indicates the interference to the base station.

Description

technical field [0001] The present disclosure relates to an electronic device and a communication method, and more particularly, the present disclosure relates to an electronic device and a communication method in a Multi-User Multi-Input Multi-Output (MU-MIMO) system. Background technique [0002] In the Long Term Evolution (LTE) system of the 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project), the MU-MIMO technology can be used to increase the system capacity of the LTE system to meet the ever-increasing traffic demand. [0003] In the MU-MIMO scheduling process, the time-frequency resources of different antennas are allocated to multiple user equipments (UEs) (also called terminal devices), so that multiple UEs can share time-frequency resources in space, thus increasing the time-frequency resources in the same The number of UEs that can be scheduled on the time-frequency resources to improve the overall scheduling efficiency. [0004] In order...
