Title:
TRANSMISSION/RECEPTION APPARATUS AND METHOD FOR WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/148462
Kind Code:
A3
Abstract:
In a PPDU transmission method for an STA apparatus, the PPDU transmission method includes the steps of: generating an HE-STF sequence; generating a PPDU which is configured based on the HE-STF sequence and includes an HE-STF field having a period of 1.6 µs; and transmitting the PPDU where the HE-STF field included in the PPDU is transmitted through a channel, wherein the HE-STF sequence may be configured based on an M sequence such that when the channel is a 20 MHz channel, the HE-STF sequence has a structure of {the M sequence, 0, 0, 0, 0, 0, 0, 0, the M sequence}, when the channel is a 40 MHz channel, the HE-STF sequence is configured based on a structure in which the HE-STF sequence over the 20 MHz channel is duplicated twice to be frequency-shifted, and when the channel is a 80 MHz channel, the HE-STF sequence is configured based on a structure in which the HE-STF sequence over the 40 MHz channel is duplicated twice to be frequency-shifted.
