Problems solved by technology

On the other hand, beamforming is generally aimed at users at the edge of the cell, so the transmission power is relatively large. Once adjacent cells use the same CSI-RS resources to transmit beamforming CSI-RS, the interference will be very serious.
On the other hand, in the serving cell, using the same CSI-RS resource to transmit beamforming CSI-RS to two user equipments will also cause certain interference

Abstract

The invention relates to an electronic device and wireless communication method for a wireless communication system. The electronic device comprises one or more processing circuits, and is configured to carry out the following operations: responding to the measurement indication from a base station in the wireless communication system, and respectively measuring the CSI-RS (channel state information reference signal) of one or more antenna ports; generating feedback information based on a measurement result, so that the base station selects one antenna port for transmitting the CSI-RS to the electronic device, wherein the feedback information comprises the information of occupying conditions of each antenna port. According to the invention, the electronic device and method can select ports for the CSI-RS, reduce the impact on the CSI-RS from beam forming between cells and in cells, improve the performance of a system, and can be achieved at a very low signaling cost.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and in particular to an electronic device in a wireless communication system and a method for performing wireless communication in the wireless communication system. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] CSI-RS (Channel State Information-Reference Signals, Channel State Information Reference Signals) was introduced in the R10 (Release 10, version 10) version of the LTE-A (Long Term Evolution-Advanced, Advanced Long Term Evolution) system for obtaining Channel state information. Beamforming is a signal preprocessing technology based on antenna arrays. Beamforming generates directional beams by adjusting the weighting coefficients of each array element in the antenna array, so that significant array gain can be obtained. Therefore, beamforming technology has ...
