Title:
METHOD AND DEVICE FOR TRANSMITTING OR RECEIVING SIGNAL IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/071993
Kind Code:
A1
Abstract:
A method and a device for transmitting or receiving a signal in a wireless communication system, disclosed in the present specification, allow uplink switching to be performed among three or more bands. Disclosed are methods for clarifying a band at which one Tx chain not used for a 1-port transmission from among two Tx chains is located after uplink switching if only the 1-port transmission exists on a carrier of one band, as a transmission after uplink switching
