Problems solved by technology

[0012] However, a possible violation of the reciprocity assumption is that when there is interference in the radio channel, it is basically possible for this interference to interfere only in one direction, for example only in the direction of reception at the terminal device

Embodiment Construction

[0068] In the following, exemplary embodiments of the present invention are described in more detail. It is to be understood that the features of the various exemplary embodiments described herein may be combined with each other unless specifically stated otherwise. Any coupling between components or devices shown in the figures may be direct or indirect, unless specifically stated otherwise.

[0069] figure 1 A wireless multiple-input multiple-output (MIMO) system 10 comprising a base station 20 and terminal devices 30 is schematically shown. The MIMO system may include a number of other terminal devices served by the base station 20, but are not shown in the figures for reasons of clarity. The base station 20 comprises an antenna array 22 comprising a plurality of antenna elements, three of which are denoted by reference numerals 23 to 25 . The base station 20 may have a large number of antenna elements 23 to 25, for example several tens or more than one hundred or one th...

Abstract

The present application relates to a method for operating a device (30) of a wireless multiple-input and multiple-output (MIMO) system (10) providing wireless communication. An interfering signal interfering the wireless communication is detected (107) and a transmit beamforming parameter is determined (108) based on the detected interfering signal. A beamformed pilot signal using the transmit beamforming parameter is transmitted (111).

Description

technical field [0001] The present invention relates to a method of operating an apparatus providing a wireless multiple-input multiple-output (MIMO) system for wireless communication. In particular, the invention relates to a method of operating terminal devices and a corresponding cooperating method of operating a base station for determining transmit and receive beamforming parameters to be communicated between these devices. The invention also relates to devices for carrying out these methods. Background technique [0002] To meet the ever-increasing demand for data and voice communications in everyday life, including personal communications via mobile phones, smartphones, and machine-type communications (MTC) such as Internet of Things (IOT) communications, so-called multiple-input multiple Output (MIMO) techniques are used in wireless communication systems such as wireless cellular telecommunication systems. [0003] In a MIMO system, multiple transmit and receive an...
