Method and apparatus for transmitting and receiving control channel by beamforming in a wireless communication system
First Claim
1. A method for transmitting control information in a wireless communication system, the method comprising:
- generating a plurality of control information sets including resource allocation information for data transmission;
identifying transmission beams for use in beamforming transmission of the plurality of control information sets;
generating a first control format indication related to at least two first control information sets corresponding to a same first transmission beam from among the plurality of control information sets, wherein;
the at least two first control information sets are successively arranged in a control channel resource region,the first control format indication includes information about the first transmission beam and information about a resource region within the control channel resource region in which the at least two first control information sets are arranged, andthe first control format indication is arranged before the at least two first control information sets;
transmitting a control signal including the first control format indication and the at least two first control information sets on the control channel resource region; and
performing data transmission with at least one mobile station based on the control signal.
