USER EQUIPMENT AND BASE-STATION DEVICE

Title:

USER EQUIPMENT AND BASE-STATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2020/208744

Kind Code:

A1

Abstract:

This user equipment has: a reception unit for receiving, from a base-station device, a first radio resource control (RRC) message for making an enquiry about capabilities of the user equipment; a transmission unit which, in response to the first RCC message, transmits, to the base-station device, a second RCC message for reporting UE capabilities, inclusive of a scaling factor which is a parameter used to calculate a maximum data rate; and a communication unit which carries out communication with the base-station device on an uplink or a downlink that is scheduled within the maximum data rate calculated on the basis of the scaling factor, wherein, in the transmission unit, an identical value is assigned to scaling factors that correspond to bands that belong to the same frequency range (FR).
