METHOD AND SYSTEM FOR CHANNEL DATA TRANSMISSION IN WIRELESS NETWORK

摘要

Disclosed are a method and system for channel data transmission in a wireless network. The method comprises: after a sending station and a receiving station determine a channel bandwidth to use for data transmission by way of interactive negotiation, the sending station sending data to the receiving station with the determined channel bandwidth. Further disclosed is a sending station. The present invention can solve the collision problem caused by contention for channels between the currently available hidden station and the current transmission station, and thus can take full advantage of the effective transmission bandwidth in the large bandwidth system of a wireless network and increase the frequency spectrum utilization of large bandwidth, and at the same time ensure the backward compatibility of the large bandwidth system and its co-existence with conventional systems.
