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： A wireless communication system in which each of communication stations performs networking operation in an autonomous, distributed manner, wherein each of the communication stations gathers information indicative of a band use situation in peripheral stations, grasps bands usable and unusable by the own station from the gathered information to set a band to be actually used by the own station, and mutually recognize bands to be used and unusable by the own station by informing to the peripheral stations.

摘要： The present invention eliminates a transmission-waiting operation which is unnecessary while accommodating a prioritized traffic. Although a communication station enters a transmission-disallowed state in response to detection of a signal addressed to another station in accordance with medium access control based on CSMA, if the communication station receives a frame transmitted with priority to a local station during the transmission waiting, it cancels the transmission-disallowed state, sends back a frame responding the frame transmitted with priority and effectively operates a transmission prioritized period. The communication station starts a search procedure to perform a processing of evading duplication of the transmission prioritized periods if it judges a possibility of a problem occurring in a time zone in which reception with priority is possible.

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.
