Abstract: A transmission method comprises: generating a transmission signal including OFDM symbols, wherein the last OFDM symbol of the OFDM symbols can be partitioned into four segments, and wherein the generating includes: computing an initial padding factor value associated with one of the four segments and computing an initial number of OFDM symbols; determining a user with a longest packet duration among plural users; determining a common padding factor value being the initial padding factor value and a common number of OFDM symbols being the initial number of OFDM symbols of the determined user with the longest packet duration; adding pre-FEC padding bits toward one of four possible boundaries of the last OFDM symbol, the one of four possible boundaries being represented by the determined common padding factor value; and adding post-FEC padding bits in remaining segment(s) of the last OFDM symbol; and transmitting the generated transmission signal.

Abstract: A transmission apparatus of the present disclosure comprises a packet generator which, in operation, generates a packet and a transmitter which, in operation, transmits the generated packet. The packet includes a legacy short training field, a legacy long training field, a legacy signal field (L-SIG), a repeated legacy signal field (RL-SIG), a first non-legacy signal field, a second non-legacy signal field, a non-legacy short training field, a non-legacy long training field and a data field, wherein the second non-legacy signal field is optionally present. The packet generator generates the packet by configuring the RL-SIG in different ways according to a presence or absence of the second non-legacy signal field in the packet.
