Patent ID: 7633970

Claim:
A method of generating an aggregate PHY frame for one or more MAC sub-frames, the method comprising: (a) generating a MAC header unit from headers of a first set from said one or more MAC sub-frames, the MAC header unit having header information applicable to each MAC sub-frame in the first set; (b) for each MAC sub-frame in the first set, generating a compressed-header data unit having a compressed header portion and a payload data portion; and (c) forming the aggregate PHY frame containing the generated MAC header unit and the generated one or more compressed-header data units, wherein: the MAC header unit has (i) a frame control field and (ii) a frame check sequence (FCS) having error detection/correction information for the MAC header unit; and each of the one or more compressed-header data units has (i) a respective frame control field and (ii) a respective frame check sequence (FCS) having error detection/correction information for the compressed-header data unit; wherein the MAC header unit has no user data.
