Title: NON-ORTHOGONAL MULTIPLE ACCESS METHOD BASED ON SCHEDULING AND COMPETITION FINE-GRAINED FUSION
Abstract:
Provided is a non-orthogonal multiple access method based on scheduling and competition fine-grained fusion, which relates to the technical field of communications. A resource area and a resource position occupied by a scheduling-competition fusion access mode are calculated, and a resource is allocated to a scheduling user; a central node sends a resource allocation indication frame to a user equipment of the present cell; and finally, information sent by the scheduling user and information sent by a competition user are superposed on a time frequency resource by means of scheduling-competition fusion access, and a receiving end parses the superposed information by means of multi-user combined detection. By using the method of scheduling access and competition access sharing the same frequency spectrum resource, the present invention achieves fine-grained fusion of two access modes, thereby facilitating the matching of a dynamically changed demand and a resource, facilitating a multi-user diversity gain, and thus significantly improving a network capacity, a frequency spectrum utilization rate and a service quality.
