Document Type and Number:
WIPO Patent Application WO/2016/163542
Kind Code:
A1
Abstract:
Provided are a beam selection method, a mobile station, and a base station. This mobile station includes: a reception unit that receives information instructing a first amount of reference signal resources and, on the basis of the information, receives a beam corresponding to a reference signal in said first amount of reference signal resources; and a selection unit that performs channel estimation on the basis of the received beam. The mobile station performs channel estimation and feedback on the basis of a reference signal in the reference signal resource notified by the base station and, as a result, reduces the workload and signaling overheads of the mobile station.
