Title:
TERMINAL, BASE STATION, AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/080085
Kind Code:
A1
Abstract:
In a transmission switching scheme in which at least one antenna port among a plurality of antenna ports can switch a band between two or more bands, and a band used for transmission is switched between a total of three or more bands of the plurality of antenna ports, a terminal is provided with a reception unit for receiving, from a base station, a particular parameter notified in an RRC message, and a control unit assuming the presence or absence of a configuration for UL MIMO for up to two ports in a band for which transmission switching is set on the basis of whether the particular parameter has been received.
