Abstract

Logic may compress wireless communications frames and communicate compressed frames that do not include the duplicative bit sequences within the packet flow. Logic may include the compressed frames in flow frames. Logic may generate, encode, transmit, decode, parse, and interpret flow frames after a packet flow is created. Flow frames may comprise a flow frame control field, a compressed frame, and a frame sequence check. Logic may decompress the compressed flow frame based upon flow decompression rules associated with a flow index of the flow frame. Flow frames may include a duration field to set the network allocation vectors of other stations. And the frame sequence check may be generated based upon the entire flow frame.
