METHOD AND TRANSMISSION APPARATUS FOR MULTIPLE ACCESS IN WIRELESS COMMUNICATION SYSTEM

WIPO Patent Application WO/2017/126897

A1

Disclosed are multiple access method and apparatus capable of providing a service having minimum latency and high reliability and high throughput in a wireless communication system. The multiple access method according to the present invention comprises the steps of: allocating resources for a plurality of user terminals by space and frequency; carrying out discrete Fourier transforms, for each space, of transmission symbols which comprise a plurality of sub-symbols and which are transmitted in accordance with the allocated space and frequency resource; and applying frequency and space filters to the results of the Fourier transforms, wherein the step for applying frequency and space filters selects, for each space, a pulse-shaping filter in accordance with the location of the allocated frequency resource, and applies the selected pulse-shaping filter to the sample which is a result of a sub-symbol Fourier transformed into a frequency domain.
