Abstract:
1. A receiving device-implemented method of generating an aggregate frame for a plurality of sub-frames, each sub-frame containing user data, the method comprising the steps of: (a) the receiving device forming an aggregate data unit (ADU) from two or more sub-frames; and (b) the receiving device generating an aggregate frame comprising: (1) an aggregate frame descriptor including (i) an aggregate frame header indicating a type of frame, (ii) a value representing the number of sub-frames of the ADU, and (iii) a sub-frame descriptor including, for each of the two or more sub-frames, an address of a receiving device for the corresponding sub-frame; and (2) the ADU, wherein the addresses of receiving devices for the two or more sub-frames in the ADU are positioned, in the aggregate frame, before the ADU comprising the two or more sub-frames.
