Title:
TERMINAL DEVICE, BASE STATION DEVICE, AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/249072
Kind Code:
A1
Abstract:
This terminal device comprises: a generation unit that generates an SRS sequence; a transmission unit that transmits an SRS resource in which the SRS sequence is mapped; and a radio resource control layer processing unit that receives an upper-layer parameter. The SRS resource is constituted by at least a first number of OFDM symbols. The SRS sequence is determined at least on the basis of a cyclic shift. The cyclic shift is determined at least on the basis of a cyclic-shift initial-value. The cyclic-shift initial-value is determined at intervals of a second number of OFDM symbols. The second number of OFDM symbols is determined on the basis of the upper-layer parameter. The second number of OFDM symbols is less than or equal to the first number of OFDM symbols.
