METHOD AND SYSTEM FOR WIRELESS COMMUNICATION USING CHANNEL SELECTION AND BANDWIDTH RESERVATION

摘要

PURPOSE: A wireless communication method using the channel selection and bandwidth reservation and a system thereof are provided to reduce the collision/interference between adjacent transmissions on a data channel. CONSTITUTION: An initiator and a responder exchange reserved channel time information by using a beacon of a control channel(42). Based on the channel information, a data channel in which reservation exists is determined(43). If the data channel in which reservation exists does not exist, a data channel which has sufficient bandwidth between pre-existing reservations is determined(44). A bandwidth reservation overlapped with the channel selected for simultaneous transmission with the other stations is attempted(45).
