Title:
TERMINAL DEVICE AND BASE STATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/188892
Kind Code:
A1
Abstract:
This terminal device is provided with a transmitting unit for transmitting an SRS resource to which an n-th SRS sequence is mapped, wherein: the n-th SRS sequence is generated; the n-th SRS sequence is determined at least on the basis of an n-th cyclic shift; the n-th cyclic shift is applied for an n-th antenna port; the n-th cyclic shift is determined at least on the basis of a maximum number of cyclic shifts for the SRS resource; n is an integer between 1 and 4; and if the maximum number of cyclic shifts is 6, a first cyclic shift, a second cyclic shift, a third cyclic shift, and a fourth cyclic shift are the same.
