Title:
METHOD AND APPARATUS FOR COMPETITION-BASED TRANSMITTING OF UPLINK DATA IN WIRELESS COMMUNICATION SYSTEM TO WHICH NON-ORTHOGONAL MULTIPLE ACCESS SCHEME IS APPLIED
Document Type and Number:
WIPO Patent Application WO/2017/204471
Kind Code:
A1
Abstract:
Provided are a method and an apparatus for competition-based transmitting of uplink data in a wireess communication system to which a non-orthogonal multiple access scheme is applied. Particularly, a terminal receives, from a base station, information relating to a predefined modulation pattern for non-orthogonal multiple access. The information relating to the predefined modulation pattern includes a modulation pattern index. The modulation pattern index indicates designation of a terminal-specific modulation order for each resource element in a resource used overlappingly by multiple terminals. The terminal transmits data to the base station using the modulation order designated to each of the resource elements on the basis of the information relating to the predetermined modulation pattern.
