Abstract: A system and method are disclosed that reduce collisions on a wireless medium shared by devices associated with a wireless network, thereby improving throughput on the wireless medium. For some embodiments, a first device reserves access to the medium for a first interval, and then grants medium access to a second device for a remainder of the first interval. If the second device transmits data during the remainder of the first interval, medium access is maintained with the second device and then the second device is prevented from contending for medium access during a subsequent contention period. Otherwise, medium access is returned to the first device and the second device is allowed to contend for medium access during the contention period.
