METHOD FOR RECEIVING PHYSICAL CONTROL CHANNEL IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE USING SAME

Title:

METHOD FOR RECEIVING PHYSICAL CONTROL CHANNEL IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE USING SAME

Document Type and Number:

WIPO Patent Application WO/2020/040534

Kind Code:

A1

Abstract:

A base station in a wireless communication system is disclosed. Each base station for wireless communication comprises: a communication module; and a processor. The processor determines the number of dynamic slot format information (SFI) bits on the basis of a maximum value of a slot format combination index which can be indicated by dynamic SFI transmitted to a terminal, and monitors a physical downlink control channel (PDCCH) including the dynamic SFI on the basis of the number of the dynamic SFI bits. The slot format combination index identifies a slot format combination configured for the terminal. The slot format combination indicates a type of a symbol included in one or more slots, and the type of the symbol is one among a downlink symbol, an uplink symbol, and a flexible symbol.
