Abstract
An apparatus and method is disclosed for providing recovery and backoff rules for a hybrid coordinator of an IEEE 802.11e Quality of Service (QoS) wireless station. The invention comprises a wireless local area network that is capable of using the recovery and backoff rules of the present invention in the Medium Access Control (MAC) layer of QoS hybrid coordinators. The HC recovery and backoff rules of the present invention minimize collisions especially when hybrid coordinators from an overlapping basic service set are present.
