Title:
METHOD AND DEVICE FOR SELECTING MULTIPLE USERS AND ALLOCATING RESOURCES FOR NON-ORTHOGONAL MULTIPLE ACCESS IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/200066
Kind Code:
A1
Abstract:
The present application provides a method for allocating resources in a wireless communication system using multiple antennas. Here, the method for allocating resources may comprise the steps of: transmitting a reference signal to first-type terminals on the basis of type information of a plurality of terminals; receiving channel estimation information from the first-type terminals that have received the reference signal; generating beams on the basis of the received channel estimation information; and allocating resources for the generated beams. Here, if the resources for the beams are allocated, first-type beams for the first-type terminals are primarily generated and allocated, and on the basis of the generated first-type beams, second-type beams for second-type terminals may be non-orthogonally generated and allocated.
