摘要： In order to realize low power consumption of a communicator and information transmission in short packets with a short latency in a network environment of a self-organized distribution type, each communication station performs a reception processing before and after a beacon transmission time of a next communication station which transmits a beacon next to a local station, and performs data transmission before and after a beacon transmission time of a communication station functioning as a data transmission destination. In a case where a certain communication station transmits information to all other communication stations, each communication station transmits information by utilizing a reception period provided after the beacon transmission time of the next communication station transmitting the beacon next to the local station to perform transmission according to a bucket-brigade system.

摘要： Random access operation is performed under a communication environment in which a plurality of communication modes having different transmission rate coexist with small overhead. A high-grade communication station spoofs information of a packet length and a rate in a decoding portion so that a value of (packet length)/(rate) corresponds to a duration where the communication is hoped to be stopped. The other station receiving the spoofed information receives the rest of the packet with the designated rate during the interval designated by the value of (packet length)/(rate). In this case, the packet length and the rate are not those of actually transmitted packet so that this packet is discarded.

摘要： Access control based on CSMA is favorably carried out with the RTS/CTS method used together. If the RTS/CTS procedure is used together, CTS information is transmitted in response to the reception of RTS information, and data is transmitted in response to the reception of CTS. The CTS transmitting station measures the quality of RTS receive signal, and thereby determines a transmission rate at which it can receive and notifies a station as the destination of CTS. The station as the destination of CTS transmits data in response to CTS information. As the transmission rate for this data, the transmission rate indicated in the RATE field in CTS is applied.

摘要： It is necessary to solve problems caused when constituting a communication system such as a radio LAN using an independent distributed type network without the controlling-controllable relationship of a master station and a slave station. In the radio communication system consisting of a plurality of communication stations having no relationship of a controlling station and a controllable station, each communication station transmits a beacon describing information on the network, thereby constituting a network. Through this beacon, it is possible to make a sophisticated judgment on the communication state in the other communication station.

摘要： A learning on a weight of an adaptive array antenna which becomes necessary for a space division multiple access is carried out while a backward compatibility with a conventional standard is maintained.When a TRQ frame and a training frame for the learning are exchanged, a spoof is applied on these frames to preferably avoid collisions with a surrounding station STA4 that follows a conventional standard. Also, after the weight of the adaptive array antenna is learnt, a STA0 multiplexes and transmits the plurality of data frames addressed to a plurality of users while a wireless resource on a spatial axis is shared by the plurality of users, so that a throughput for one-to-many, that is, for the plurality of users as a whole is improved.
