Abstract

The present disclosure relates to an electronic device and a wireless communication method in a wireless communication system. The electronic device includes: one or more processing circuits configured to perform the following operations: determine a corresponding transceiver unit TXRU configuration based on the antenna array corresponding to the electronic device, wherein each TXRU has the same polarity It is related to a group of antenna units in the polarization direction, the antenna array has M rows, N columns and multiple antenna units in P-dimensional polarization directions, where M, N and P are natural numbers; and adding antenna configuration information to the radio resource control Used in RRC signaling for user equipment in a wireless communication system, wherein the antenna configuration information is used to obtain the number of TXRUs in the antenna array. Using the electronic device and wireless communication method according to the present disclosure, the user equipment can know the antenna configuration of the base station, so that when the user equipment estimates and measures the channel, it can comply with the configuration of the base station and improve the transmission performance of the 3D MIMO system.

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] With the development of communication technology, research on vertical beamforming / FD MIMO (Full-Dimension Multiple-Input Multiple-Output, full-dimensional multiple-input multiple-output) in LTE (Long Term Evolution, long-term evolution) has been started. Among them, the difference between the vertical beamforming / FD MIMO and the traditional transmission system lies in the introduction of the vertical dimension and the use of more antennas. [0004] Meanwhile, with the introduction of the vertical dimension, a 2D antenna array is further proposed. In additi...
