HEADER COMPRESSION ADAPTIVE TO QUALITY OF RADIO CHANNEL

Abstract:

A method of processing data for transmission in a wireless communications system, the method comprising identifying within the data a data frame having a protocol header, the protocol header comprising a plurality of protocol header fields and associated with a medium access control (MAC) frame format for data transmission within a local area network (LAN), determining a selected profile for header compression, the profile being selected from a plurality of predetermined profiles, each of the plurality of predetermined profiles specifying a subset of the protocol header fields, and applying compression to a subset of the protocol header fields in accordance with the selected profile to form a compressed data frame for transmission on a wireless access interface of the wireless communications network.
