Title:
BASE STATION DEVICE, RADIO COMMUNICATION DEVICE, AND RADIO COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/095708
Kind Code:
A1
Abstract:
[Problem] To provide a base station device, a terminal device, and a radio communication system which enable a low PAPR requirement to be satisfied in downlink communication. [Solution] A base station device according to the present disclosure is provided with a control unit which issues a notification of first information relating to a usage signal waveform, among a first signal waveform and a second signal waveform, to be used in downlink communication of an initial connection procedure performed with a terminal device, and which performs the downlink communication using the usage signal waveform, on the basis of the first information.
