ABSTRACT:
A method and apparatus providing delivery of buffered frames in a Wireless Local Area Network (WLAN) is presented. The method and apparatus determines an occurrence of at least one non-APSD station in said WLAN, and when at least one non-Automatic Power Save Delivery (APSD) station is found, then maintains a legacy power saving buffer for each non-APSD station. The method and apparatus also determines an occurrence of at least one APSD station in the WLAN, and when at least one APSD station is found, then maintains at least one APSD buffer for each APSD enabled station. During a service period, frames are transmitted from the at least one APSD buffer.
