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： There is provided a communication control device including a power distribution unit configured to distribute, to one or more secondary systems, a transmission power accepted for a secondary usage of a frequency channel which is protected for a primary system, and a notification unit configured to notify each secondary system of a value of a second transmission power which is decided depending on a value of a first transmission power distributed by the power distribution unit. Upon updating the transmission power, only in a case where a value of the second transmission power which is previously notified and a value of the first transmission power which is newly distributed by the power distribution unit satisfy a predetermined condition with respect to a certain secondary system, the notification unit notifies the secondary system of a new value of the second transmission power.

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.
