Abstract

A method and device for ultra wide band wireless medium access control, the method includes: assigning a plurality of information frames to at least one DRP queue and to at least one PCA queues; determining whether to re-assign at least one information frame previously assigned to at least one DRP queue to a PCA queue; and re-assigning at least one information frame in response to the determination. A device and method for ultra wide band wireless medium access control, the method includes: assigning a plurality of information frames to at least one DRP queue and to at least one PCA queues; and scheduling a transmission of at least one information frame assigned to at least one DRP queue during at least one PCA transmission period.
