Abstract: The various embodiments provide a mobile station having at least a first and a second radio transceivers wherein a medium access control (MAC) layer framework coordinates the transmission and reception of the at least a first and a second transceiver systems. In addition, the various embodiments employ asynchronous connectionless links (ACL) for voice traffic on a Bluetooth™ link rather than SCO links. A central scheduler (305) interfaces with a first MAC layer (311) and a second MAC layer (321). By interacting with the MAC layers of both systems, the central scheduler (305) collects traffic information from both PHY layers at the buffer (309), including transmission/reception timing, and Quality of Service (QoS) requirements for voice traffic. Based upon the collected information the central scheduler (305) will schedule transmissions by both systems in a non-time-overlapping manner so as to avoid radio frequency interference.

Abstract: Quality of Service (QoS) mechanisms and facilities are introduced into USB-based wireless Local Area Networking (LAN) communication systems. Techniques are provided for managing multiple priority queues in USB-based wireless communications systems, and for ensuring that lower priority traffic is not precluded from accessing the medium during sustained periods of use by high(er) priority traffic. A method is provided to resolve Quality of Service issues in emerging high-speed USB-based communications systems by offering support for multiple queue management within the system. A further embodiment provides an escalation mechanism for the purposes of mitigating low priority class data starvation in these communications systems, when it becomes an issue.
