Method and apparatus for operating control channels for beamforming-based wireless communication

摘要

Provided is a method and apparatus for operating a control channel in a beamforming-based wireless communication system. The provided method includes acquiring information indicating a best Base Station (BS) receive beam for Uplink (UL) communication; determining a control channel region for UL control channels in a UL interval considering the best BS receive beam, the control channel region being a predetermined region that is mapped to the best BS receive beam; and exchanging information about the control channel between a BS and a Mobile Station (MS) through the control channel region.

主权项

1. A method to receive control information, the method performed by a base station (BS) in a wireless communication system, the method comprising:
selecting a BS receive beam for uplink communication with a mobile station (MS), wherein the selected BS receive beam is one of a plurality of BS receive beams formed by an antenna array of the BS, and the plurality of BS receive beams have different beam directions and different beam coverages; identifying a control channel resource region mapped to the selected BS receive beam from among a plurality of control channel resource regions in an uplink interval, wherein the uplink interval is configured for a control channel and includes the plurality of control channel resource regions corresponding to the plurality of BS receive beams respectively, and the plurality of control channel resource regions are divided on a time domain or a frequency domain in the uplink interval; and receiving the control information from the MS on the identified control channel resource region through the selected BS receive beam.
