摘要：
A method and apparatus for providing quality of service over a contention access period of a wireless personal area network is provided herein. Particularly, the layers above the MAC are allowed to reserve portions of a contention access period (CAP) in order to schedule their QoS actions cooperatively thereby avoiding the dependence on the MAC for QoS performance. By using cooperative scheduling, a node can send a QoS packet from the QoS_Layer to the MAC, and know that it will be transmitted according to the specified QoS requirement. As a result, whenever a node sends a QoS packet in the reserved portion of the CAP, the channel will be guaranteed to be free from competing nodes' packets because those competing nodes will delay their transmissions based on the shared schedule.
