(a) associating one or more user data frames into aggregated user data in accordance with a first layer;

to the aggregated data, each sub-frame having a format in accordance with a second layer, wherein step (b) comprises the steps
of:
(b1) forming one or more sub-frames from the one or more user data frames by adding a sub-frame header in accordance with
the second layer to each corresponding user data frame,
(b2) grouping the one or more sub-frames with a predefined order based on a transmission characteristic, and
(b3) adding a descriptor to the grouped sub-frames, wherein the descriptor is an aggregate frame descriptor comprising an
aggregate frame header indicating a type of frame, a number of sub-frames, and at least one sub-frame descriptor for the sub-frames;
and
