AUFRECHTERHALTUNG DER SYNCHRONISATION ZWISCHEN EINEM QOS-ZUGRIFFSPUNKT UND QOS-STATIONEN IN EINEM DRAHTLOSEN LAN GEMÄSS IEEE 802.11E

摘要

Disclosed is a method and system for maintaining synchronization of the Service Period between a quality of service capable access point (QAP) and a non-AP quality of service capable station (QSTA) in a parameterized quality of service (QoS) IEEE 802.11e wireless local area network (WLAN). A problem with loss of synchronization between QAP and non-AP QSTAs can occur on downlink for parameterized QoS if the acknowledgement (ACK) frame for the last downlink frame in the Service Period is not received by the QAP because the non-AP QSTA goes to sleep too soon.
