Abstract: A multi-radio device includes two or more radio subsystems coupled to a packet traffic arbitration (PTA) module. The PTA module receives a first request for radio communication from a first radio subsystem, where the first request indicates a first usage duration. After granting the first request, the PTA module receives a second request for radio communication from a second radio subsystem. The second request indicates a second usage duration. The PTA module sends a rejection of the second request to the second radio subsystem, where the rejection indicates a remaining time of the first usage duration.

The first radio transceiver supports a first number of Spatial Streams (SS) for a first Transmission (Tx) opportunity of wireless transmission to a receiver.
