WIRELESS COMMUNICATION SYSTEM AND WIRELESS STATION

摘要

PROBLEM TO BE SOLVED: To provide a wireless communication system and wireless station by which communication between a base station device and a plurality of terminal devices can be efficiently performed even when SDMA (space division multiple access) is used with CSMA (carrier sense multiple access). SOLUTION: Each of the terminal devices comprises: a means to receive first data which are broadcast from the base station device; a means to receive second data which are unicast from the base station device to the terminal device; a determining means to determine the presence/absence of directional beam control in the base station device, on the basis of received power measured when the first data are received and received power measured when the second data are received; and a control means to control transmitting power of transmitting data to the base station device when the determining means determines that the base station device is performing directional beam control.
