Title:
TERMINAL, BASE STATION, AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/203705
Kind Code:
A1
Abstract:
A terminal comprises a transmission unit that transmits an uplink signal in a switching scheme that allows switching between bands of a plurality of transmission chains, a receiving unit that receives a downlink signal specifying a band for transmitting the uplink signal, and a control unit that switches any of the bands of the plurality of transmission chains to a specified band and controls the bands of the remaining transmission chains to be switched or maintained in a predefined method when the band specified by the downlink signal is not connected by the plurality of transmission chains.
