Title:
端末、無線通信方法、基地局及びシステム
Document Type and Number:
Japanese Patent JP7028646
Kind Code:
B2
Abstract:
A user terminal is disclosed that carries out communication using a predetermined radio access scheme. The user terminal includes a receiver that receives a reference signal in a specified radio resource, and carries out a reception process on the reference signal based on a specified orthogonalization application range, and a processor that determines at least one of the specified radio resource and the specified orthogonalization application range based on communication parameters used in the predetermined radio access scheme. A base station is also disclosed including a transmitter that applies orthogonalization to a reference signal based on a specified orthogonalization application range, and transmits the reference signal in a specified radio resource, and a processor that determines at least one of the specified radio resource and the specified orthogonalization application range based on communication parameters used in the predetermined radio access scheme.
