APPARATUS AND METHOD FOR CONTROL CHANNEL BEAM MANAGEMENT IN A WIRELESS SYSTEM WITH A LARGE NUMBER OF ANTENNAS

摘要

A base stations (BS) are configured to perform a coordinated transmission to at least one user equipment (UE). The BS includes a plurality of antenna configured to communicate with the UE. The BS also includes processing circuitry coupled to the plurality of antennas and configured to transmit physical downlink control channel (PDCCH) to the at least one user equipment. The UE includes a plurality of antennas configured to communicate with the BS. The UE also includes a processing circuitry coupled to the plurality of antennas and configured to receive PDCCH from the BS. The PDCCH is included in one or more transmit (Tx) beams. A Tx beam is defined by the cell specific reference signal (CRS) transmitted through the Tx beam. A Tx beam is configured to carry a beam identifier, and the PDCCH is configured to include resource allocation information for the user equipment.
