Title:
TERMINAL AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/124585
Kind Code:
A1
Abstract:
A terminal according to one embodiment of the present disclosure has a control unit for determining, on the basis of the setting information of a sounding reference signal (SRS), whether or not a time domain orthogonal cover code (TD-OCC) is valid for the consecutive symbols of the SRS, and a transmission/reception unit for performing an SRS transmission process and/or reception process on the basis of the TD-OCC when it is determined that the TD-OCC is valid. According to one embodiment of the present disclosure, it is possible to suppress a decrease in SRS capacity.
