Patent ID: 8248910

Claim:
A method comprising: distributing, by a processor, physical layer pre-signalling data among preamble symbols; in response to determining that physical layer data is not larger than a predetermined number of preamble symbols such that there is excess preamble symbol space, placing data for link layer signaling in the excess preamble symbol space or leaving the excess preamble symbol space empty; using a first permutation rule to frequency interleave odd-numbered orthogonal frequency division multiplexing symbols; using a second permutation rule to frequency interleave even-numbered orthogonal frequency division multiplexing symbols, wherein the second permutation rule differs from the first permutation rule; and assigning physical layer pre-signalling cells in a row-wise zig-zag manner into the preamble symbols, wherein physical layer pipe data comprising the link layer signaling data is mapped into excess preamble cells in top-down order.
