摘要： Space-division multiple access is optimally realized while avoiding inter-network interference.Time usage information for transmission sequence units is exchanged among different networks or non-adjacent equipment, and on the basis of this information, a station that initiates a transmission sequence unit disposes the start time of its own transmission sequence unit in a time slot which is not being used by an adjacent network or adjacent equipment. As a result, multiple wireless networks or wireless communication devices are able to utilize a channel by time division even in cases where exclusive placement of frequency channels is difficult, and efficient space-division multiple access can be realized.

摘要： Suitable beam pattern control is performed while performing access control based on physical carrier sense.A communication device transmits frames having a long preamble under a state where signals will not reach unless a beam pattern is formed, thereby enabling access control based on physical carrier sense, and under a state where signals will sufficiently reach without a beam pattern being formed transmits frames having a shorter preamble, thereby suppressing transmission overhead. Also, a beam pattern and preamble type are decided based on transmission/reception history of access control following CSMA/CA procedures.

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 includes a first communication station configured to operate according to a first communication protocol, and a second communication station capable of operating according to both the first communication protocol and a second communication protocol. When the second communication station transmits a packet according to the second communication protocol, at least a first signal field compliant with the first communication protocol and a second signal field compliant with the second communication protocol are attached to a header of the packet, and the first signal field includes a parity bit. When the second communication station receives a packet from another communication station, the second communication station performs a parity check on the first signal field of the packet, and when no parity error is detected, the second communication station further checks whether content of the first signal field is compliant with the first communication protocol.

摘要： Appropriate communication operation is performed by employing space division multiple access in which wireless resources on a space axis are shared by a plurality of users.Frame exchange is performed between an access point and terminals whereby the access point estimates delay times of the terminals and notifies the terminals of information on the delay times and the terminals perform uplink frame transmission to the access point taking a difference among the delay times into consideration. Interference among users may be reduced in the access point and throughput of a system which performs the space division multiple access is improved.

摘要： By effectively utilizing the beam pattern used at the time of the last communication, a directional link can be efficiently established, thereby reducing overhead.When establishing a link, a communication apparatus 100 transmits a preparation frame by using the last used transmit beam pattern, thereby efficiently establishing a directional link and reducing overhead. Also, when establishing a link, the communication apparatus 100 uses the last used receive beam pattern to receive a preparation frame whose transmission timing is known, thereby efficiently establishing a directional link and reducing overhead.
