Title:
METHOD FOR GENERATING AND TRANSMITTING DOWNLINK PREAMBLE IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/056507
Kind Code:
A1
Abstract:
Disclosed is a method for generating and transmitting a downlink preamble in a wireless communication system supporting variable tone spacing (VTS). The disclosed method for generating a downlink preamble comprises the steps of: determining a tone spacing interval for a first user terminal and a second user terminal; generating a first preamble having a length determined according to a first tone spacing interval for the first user terminal; generating a second preamble having a length determined according to a second tone spacing interval for the second user terminal; and overlapping the first preamble and the second preamble to generate a third preamble to allow a cyclic prefix (CP) of the second preamble to be located between preamble sequences.
