LDPC ENCODED PROCESS WITH LONGER LDPC CODE WORD LENGTH IN UHR

An apparatus and method of encoding Low-Density Parity Check (LDPC) Physical Layer Convergence Protocol (PLCP) packet protocol data units (PPDU) is disclosed. For LDPC codeword of lengths 3888 and/or 7776, the number and length of codewords to use may depend on the number of available bits. In this...

description An apparatus and method of encoding Low-Density Parity Check (LDPC) Physical Layer Convergence Protocol (PLCP) packet protocol data units (PPDU) is disclosed. For LDPC codeword of lengths 3888 and/or 7776, the number and length of codewords to use may depend on the number of available bits. In this case, if the number of available bits is larger than 1944 and less than 2596, two codewords of length 1944 or a single codeword of length 3888 to encode the PPDU is used to encode the PPDU. For larger numbers of available bits, one or more codewords of length 3888 or 7776 is used to encode the PPDU. Shortening and/or puncturing, when used, is also based on the number of available bits.
