Title:
COMMUNICATION SYSTEM, BASE STATION AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/194021
Kind Code:
A1
Abstract:
Provided is a highly reliable communication system or the like. This communication system is provided with: a base station; and a plurality of terminal devices configured to be able to wirelessly communicate with the base station. When 1 slot includes a sounding reference signal (SRS) symbol range that is formed of one or more symbols allocated for an SRS of a first terminal device, a first symbol range that is formed of one or more symbols before the SRS symbol range, and a second symbol range that is formed of one or more symbols after the SRS symbol range, a second terminal device, which is different from the first terminal device, performs uplink communication to the base station in at least one among the first symbol range and the second symbol range.
