Packet priority setting method and apparatuses for a wireless terminal

First and second wireless transceiver units (TX1, TX2) operate in the same portion of the RF spectrum. An arbitration device (130) controls when the first and second wireless transceiver units (TX1, TX2) can operate. An interface (151-154) connects the first transceiver unit (TX1) to the arbitration device (130) and receives requests for operation. The interface permits the transceiver unit (TX1) to use one of N possible priority levels (e.g. N=2) for requests. The transceiver (TX1) associates a transceiver priority level to a series of packets which is chosen from a range of M possible priority levels (where M>N, e.g. M=8). The transceiver unit (TX1) sends a sequence of requests to operate to the arbitration device, each request in the sequence having a priority level chosen from the range of N possible priority levels. The average value of the priority levels used in the sequence depends on the associated transceiver priority level.
