A wireless communication unit for a wireless communication system transmits and receives video, audio and data signals within an RF bandwidth. The RF bandwidth is allocated among the video, audio and data signals to allow the video, audio and data signals to fit within the RF bandwidth. The allocation is performed by buffering the signals, making priority assignments to each of the buffered signals, and transmitting the buffered signals according to the priority assignments. The transmitted signals occupy the RF bandwidth in portions specified by the priority assignments. The priority assignments can be changed during a communication link. The subscriber unit receives a transmission header from another party on the communication link, which may include a request by the other party to change the priority assignments. If such a request is received, the subscriber unit automatically changes the priority assignments in response to the request. The communication unit is applicable to subscriber units and base stations. One such subscriber can be a cellular telephone having full-motion video capability.
