Abstract: 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.

Abstract: To suitably perform information transfer, while suppressing interference to other terminal stations, and preventing a reduction of a transmission opportunity of other terminal stations.A terminal station estimates a distance of another terminal station (within a receivable range), from an MCS or RSSI, for example, and controls a transmission power of itself, in accordance with a value weighted with respect to distance. For example, in the case where it is estimated that a number of terminal stations with a far distance has increased, from the value weighted with respect to distance, a transmission power of itself is lowered. As a result of this, transmission by multi-hop is explicitly performed, and it is possible to suppress electric wave interference of a multi-hop destination.

Abstract translation: 为了适当地执行信息传送，同时抑制对其他终端站的干扰，并且防止其他终端站的传输机会的减少。 终端基于例如MCS或RSSI估计另一终端站（在可接收范围内）的距离，并且根据对距离进行加权的值来控制其本身的发送功率。 例如，在估计远距离的终端的数量增加的情况下，从相对于距离加权的值，本身的发送功率降低。 作为其结果，显式地进行多跳的发送，可以抑制多跳目的地的电波干扰。
