FRAME AGGREGATION
First Claim
1. A method of generating a frame of aggregated data, the method comprising the steps of:
- (a) associating one or more user data frames into aggregated user data in accordance with a first layer;
(b) generating, at an aggregation layer, two or more sub-frames from the aggregated user data by adding at least one header to the aggregated data, each sub-frame having a format in accordance with a second layer; and
(c) forming an aggregated frame from the two or more sub-frames in accordance with a third layer.

Abstract
A packet network employs frame aggregation to reduce the number of physical-layer frames employed to transfer a given amount of user data. A packet network might employ physical (PHY) and medium access control (MAC) layers of a wireless local area network (WLAN) operating in accordance with one or more IEEE 802.11 standards. Frame aggregation combines several separate, higher-layer frames with user data into one PHY-layer frame, thus increasing the amount of user data per PHY-layer frame transmitted. Frame aggregation improves the efficiency by reducing both PHY-layer overhead and MAC-layer overhead.
