1. A method implemented by a device for bit padding, for orthogonal frequency division multiplexing (OFDM) transmission, comprising:
receiving an unpadded data payload for the OFDM transmission, the unpadded data payload includes service field and tail bits; encoding the unpadded data payload; adding the bit padding to include padded symbols to the encoded data payload, wherein number of padded symbols is computed and based at least upon number of OFDM symbols, even-number tone counts of data tones, and number of media access control (MAC) layer bytes, wherein a number of bits added to the encoded data payload is defined by the equation
Npad=NSYM*NSD−(NMACBYTES*8+16+6),wherein Npad comprises the number of bits to be added, NSYM comprises the number of OFDM symbols, NSD comprises the even-number tone counts of data tones, and NMACBYTES comprises the number of bytes in the unpadded data payload; and outputting a minimal number of OFDM symbols. |
