2 2D ACTIVE ANTENNA ARRAY OPERATION FOR WIRELESS COMMUNICATION SYSTEMS

摘要

This disclosure relates to a 5G (5 ^th generation) or pre-5G communication system to support higher data rates since 4G (4 ^th generation) communication systems such as Long Term Evolution (LTE). A method for operating a large antenna array in a wireless communication system includes receiving one or more signals by a base station. The one or more signals include information for beamforming for multiple terminals using a full-dimensional multiple-input multiple-output (FD-MIMO) beamforming scheme. The FD-MIMO beamforming scheme includes the same time resources and the same frequency resources that are jointly scheduled to the plurality of UEs. The method includes identifying a time delay of the one or more signals associated with one or more antenna arrays distributed by the base station to the large-scale antenna array and determining a time delay of the multi-user multi-user, MU) joint beamforming.
