Title:
METHOD AND APPARATUS FOR SIGNAL DETECTION IN A MIMO COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/127216
Kind Code:
A1
Abstract:
Embodiments of the present disclosure relate to methods and apparatuses for signal detection in a MIMO communication system. A receiver device according to an embodiment of the present disclosure comprises a remote unit and a baseband unit. The remote radio unit is configured to receive a first set of signals from a first number of receiving antennas, and the baseband unit comprises: an interfacing unit, configured to obtain the first set of signals from the remote radio unit; a beamforming unit, configured to generate a second set of signals associated with a second number of virtual antennas by performing receiving beamforming for the obtained first set of signals, the second number being less than the first number; and a detecting unit, configured to detect the second set of signals generated by the beamforming unit. Embodiments of the present disclosure may reduce complexity of signal detection and cost of implementation.
