Techniques for encoding PLCP headers

摘要

A method (400) and apparatus for encoding a block-based communication system header. A physical (PHY) layer header and a medium access control (MAC) header of the block-based communication system header are encoded to generate parity bits, wherein the PHY layer header includes at least cyclic prefix (CP) mode bits (S410). Parity bits are appended to the PHY layer header and the MAC layer header to generate a bit vector (S420). The bit vector is divided into at least two data blocks, wherein a first data block includes at least the CP mode bits (S430). A predefined number of tail bits are appended to each data block (S440). The two data blocks are mapped into at least two symbols, wherein the first data block is mapped to a first symbol, such that the first symbol is a first header symbol being transmitted (S450).

1. A method for encoding a block-based communication system header, comprising:
encoding a physical (PHY) layer header and a medium access control (MAC) header of the block-based communication system header to generate parity bits by using a systematic error correcting code, wherein the PHY layer header includes at least cyclic prefix (CP) mode bits, wherein said CP mode bits define a time duration of a guard interval; appending the parity bits to the PHY layer header and the MAC layer header to generate a bit vector; dividing the bit vector equally into first and second data blocks, wherein the first data block includes at least the CP mode bits; appending a predefined number of tail bits to each data block of the first and second data blocks; and mapping the first and second data blocks into at least two symbols, wherein the first data block is mapped to a first symbol, and wherein the first symbol is to be transmitted before the second symbol.
