Abstract
An apparatus and method for wireless communication is described in which post-Forward Error Correction (FEC) padding in a Physical Layer Convergence Procedure (PLCP) Protocol Data Unit (PPDU) is replaced with non post-FEC data. The data signals include repeating codebits or quadrature amplitude modulation (QAM) symbols of the last codeword. In addition, the coding rate, modulation order, orthogonal frequency division multiplexed (OFDM) symbol duration, and/or transmission bandwidth is able to be reduced, less power is allocated to padding subcarriers, a pre-FEC padding factor is increased, and/or control information piggybacked in the padding. The replacement may be limited to short PPDUs or those exceeding a threshold length. An increase in packet extension duration allows additional processing time.
