DEVICE AND METHOD

Document Type and Number:

WIPO Patent Application WO/2016/084460

Kind Code:

A1

Abstract:

[Problem] To enable radio resources to be used more efficiently in non-orthogonal multiple access. [Solution] Provided is a device provided with: a grouping unit which, on the basis of the size of transmission data of each of a plurality of terminal devices that support non-orthogonal multiple access, groups the plurality of terminal devices; and an allocation unit which allocates the same radio resource on a group-by-group basis, the respective groups being obtained as a result of the grouping.
