Abstract
A method of operating a wireless device is provided in which a number of neighboring nodes is estimated, a medium access priority to access a communication resource in a current timeslot is determined, and whether to transmit a scheduling control signal in the current timeslot is determined based on the number of neighboring nodes and the medium access priority.
Claims52
