Communication control method and communication control apparatus

A communication control method for a wireless communication system including a first wireless station and a second wireless station,

• the communication control method comprising:
• simultaneously transmitting, by the first wireless station, identical beam specifying signals respectively including an identical beam identifier from a plurality of antennas to the second wireless station by transmission beams associated with the identical beam identifier;
• receiving, by the second wireless station, the identical beam specifying signals transmitted from the first wireless station;
• selecting, by the second wireless station, a selected beam including the identical beam identifier, the selected beam being selected on a basis of reception qualities of the identical beam specifying signals;
• transmitting, by the second wireless station, a report signal indicating the selected beam to the first wireless station;
• receiving, by the first wireless station, the report signal by at least one of the plurality of antennas;
• and
• selecting, by the first wireless station, a transmission beam associated with the identical beam identifier as a transmission beam to be used for communication with the second wireless station.

A communication control device comprising:

• a transceiver that simultaneously transmits identical beam specifying signals respectively including an identical beam identifier from a plurality of antennas to a wireless station by transmission beams associated with the identical beam identifier;
• a receiver that receives, by each at least one of the plurality of antennas, a report signal indicating a selected beam including the identical beam identifier, the selected beam being selected on a basis of reception qualities of the identical beam specifying signals in the wireless station;
• and
• a selector that selects a transmission beam associated with the identical beam identifier as a transmission beam to be used for communication with the wireless station.
