Title:
USER TERMINAL, WIRELESS BASE STATION, AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/090708
Kind Code:
A1
Abstract:
The present invention realizes proper communication in a next-generation communication system. A user terminal according to one embodiment of the present invention is one that carries out communication using a prescribed wireless access scheme, and that is characterized by having: a reception unit that receives a reference signal using a specific wireless resource and performs a reception process on the reference signal on the basis of a specific orthogonalization application range; and a control unit that determines the specific wireless resource and/or the specific orthogonalization application range on the basis of communication parameters used in the prescribed wireless access scheme.
