摘要： Apparatuses and methods for maintaining an optimal beam direction in a wireless communication system are provided. The method for operating a receiving node in a wireless communication system includes, determining a first transmission beam is determined as a preferred transmission beam using a plurality of reference signals transmitted by a transmitting node, generating preferred transmission beam information, transmitting the preferred transmission beam information to the transmitting node, receiving transmissions from the transmitting node via the first transmission beam, and determining whether a change of a transmission beam is necessary. When the change of the transmission beam is determined to be necessary, generating a beam change request and transmitting the beam change request to the transmitting node.

摘要： Disclosed is a method of transmitting common control information by a base station in a communication system including a first communication system and a second communication system different from each other. In the communication system, a frame for carrying the common control information includes an uplink sub-frame and a downlink sub-frame, each of which includes a resource allocation area for the first communication system and a resource allocation area for the second communication system. The method includes: configuring the common control information to be received by a mobile station belonging to the second communication system; and transmitting the common control information through the resource allocation area for the second communication system included in one of the uplink sub-frame and the downlink sub-frame.

摘要： A method and apparatus for transmitting and receiving data in a communication system using beamforming are provided. The transmission method includes transmitting a control channel signal in a control channel region of a subframe using a first transmission beam of a base station. The transmission method also includes transmitting a data signal during a predetermined time period of a data region after the control channel region in the subframe using a second transmission beam determined based on the first transmission beam. The transmission method further includes transmitting a data signal in a remaining data region following the predetermined time period using a scheduled transmission beam.

摘要： A Base Station (BS) cooperative communication method in a wireless communication system is provided. The BS cooperative communication method includes measuring signal quality of one or more neighboring BSs, comparing a number of downlink beams available for communication between a serving BS and a Mobile Station (MS) with a reference value, determining not to involve the one or more neighboring BSs in BS cooperative communication for the MS when the number of downlink beams is equal to or larger than the reference value, comparing signal measurements of the one or more neighboring BSs with a first threshold when the number of downlink beams is smaller than the reference value, and determining to involve one or more neighboring BSs having a signal measurement value larger than the first threshold in the BS cooperative communication for the MS.
