Method for carrying out communications among plural stations

摘要

A communications method achieving high transmission efficiency is provided. Provided with permission for communications in a specified time period (P1), a wireless station (2) calculates the number of packets transmittable in the time period (P1), and successively sends a series of data packets (109) through (112). A wireless station (3) receives the series of data packets, and then sends a response packet (113). When the wireless stations (2 and 3) completes communications before the time period (P1) passes, a control station (1) forcefully terminates the permission for the communications.
