Abstract: A Multiple-Input Multiple-Output data transmission system includes access stations and an access point having multiple receive antennas. An access point has a minimum contention window size decision unit to determine a minimum contention window size based on the number of receive antennas and a number of access stations, a broadcasting unit to broadcast the determined minimum contention window size to the access stations, and a receiver to receive data from the access stations in a contention window that is calculated based on the minimum contention window size. An access station receives the minimum contention window size from the access point, determines a first contention window size based on the minimum contention window size, and transmits data to the access point within the first contention window. If the transmission fails, the access station determines a second contention window size and retransmits the data in the second contention window.
