摘要： The present invention provides a wireless communication system that performs a communication using directional beams formed in a plurality of directions including at least a first wireless terminal station (1) that transmits beam transmission direction identification information in all directions, in which the information can be transmitted, over a period designated from a wireless base station (0) and a second wireless terminal station (2) that performs reception operation for the transmission direction identification information, which is transmitted from the first wireless terminal station (1), in all reception directions over a period designated from the wireless base station (0), combines reception direction identification information and the transmission direction identification information at the reception of the transmission direction identification information to specify the combined reception direction identification information and the transmission direction identification information as directivity direction combination information, and transmits the directivity direction combination information to the wireless base station. The first wireless terminal station (1) and the second wireless terminal station (2) form directional beams in directions indicated by the directivity direction combination information to thereby perform a direct communication.

摘要： A base station of a radio communication system emits a radio wave having the same frequency by time division toward a plurality of specific areas from a plurality of antenna elements by using a multiple-beam antenna to form a plurality of spot beams, and transmits broadcast information through a plurality of beacon channels. Upon reception of the broadcast information, a terminal that exists in any one of the plurality of specific areas selects an optimum beacon channel, and transmits a communication establishment request and a bandwidth request to the base station through a request channel corresponding to information for identifying the antenna element, which is included in the broadcast information received through the selected optimum beacon channel. Upon reception of the requests, the base station schedules, when a channel is to be allocated, a channel allocation time including downlink and uplink data bandwidths and the like.
