4X LTF SEQUENCE DESIGN FOR WIDE BANDWIDTHS IN WIRELESS COMMUNICATIONS

Title:

4X LTF SEQUENCE DESIGN FOR WIDE BANDWIDTHS IN WIRELESS COMMUNICATIONS

Document Type and Number:

WIPO Patent Application WO/2024/055989

Kind Code:

A1

Abstract:

Various schemes pertaining to four times (4x) long-training field (LTF) sequence design for wide bandwidths in wireless communications are described. A processor of an apparatus generates an LTF of a physical-layer protocol data unit (PPDU) with a 78.125kHz subcarrier spacing by using a predefined LTF base sequence. The apparatus then performs a wireless communication in a 240MHz, 480MHz or 640MHz bandwidth with the PPDU.
