Wireless communication system, wireless communication apparatus, wireless communication method, and computer program

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.

主权项

1. An electronic device used in a wireless communication system, comprising:
processing circuitry configured to receive a legacy signal and a high throughput (HT) signal, the legacy signal and the HT signal being received in a single packet; demodulate the HT signal according to a second signal point location, which defines a second arrangement of signal points in a signal space, that is different from a first signal point location, which defines a first arrangement of signal points in a signal space, used to demodulate the legacy signal, wherein the legacy signal includes length information, and the HT signal includes length information for a station capable of decoding the HT signal.
