COMMUNICATION DEVICE, COMMUNICATION METHOD AND PROGRAM

Document Type and Number:

WIPO Patent Application WO/2017/169199

Kind Code:

A1

Abstract:

[Problem] To improve the efficiency of processing relating to the transmission of a reference signal and feedback of a measurement result. [Solution] A communication device provided with a control unit which, on a radio-resource-by-radio-resource basis, measures a terminal-specific reference signal transmitted in a radio resource assigned to each terminal device, and transmits information indicating a measurement result.
