Title:
TERMINAL DEVICE, AND BASE STATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/026673
Kind Code:
A1
Abstract:
This terminal device is provided with an uplink reference signal generating unit for generating a reference signal, and a receiving unit for receiving control information including, at least, a number of allocated subcarriers and information relating to bandwidth extension, the control information being transmitted from a base station device, wherein the uplink reference signal generating unit generates a Zadoff-Chu sequence on the basis of the number of subcarriers after extension, calculated on the basis of the number of allocated subcarriers and the information relating to bandwidth extension, and cyclically extends the generated Zadoff-Chu sequence to generate a reference signal sequence having the same sequence length number as the number of subcarriers after extension.
