Abstract: A base station in a wireless communication system is provided. Each base station for wireless communication comprises: a communication module; and a processor. The processor is configured to determine the number of dynamic slot format information (SFI) bits based on a maximum value of a slot format combination index which can be indicated by dynamic SFI transmitted to a terminal, and monitor a physical downlink control channel (PDCCH) including the dynamic SFI based on 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.

Abstract: The present specification relates to a method, an apparatus, and a system for transmitting uplink control information in a wireless communication system. The present specification provides a terminal comprising: a processor configured to determine a UCI to be dropped from among a first UCI having a first priority and a second UCI having a second priority or to multiplex the first UCI and the second UCI, under the condition in which a first PUCCH, to which the first UCI is mapped, and a second PUCCH, to which the second UCI is mapped, overlap in at least one symbol with respect to time; and a communication module configured to transmit an undropped UCI from among the first UCI and the second UCI to a base station or transmit a third PUCCH, in which the first UCI and the second UCI are multiplexed to be mapped thereto, to the base station according to the control of the processor. Communication reliability can be increased by multiplexing and transmitting UCIs having different priorities or later retransmitting a dropped UCI.

Abstract: The present invention provides a method, device, and system for adjusting a contention window size for performing channel access. The method includes: receiving uplink scheduling information on the uplink transmission including a new data indicator (NDI) associated with a specific subframe in a first uplink transmission burst; determining a contention window size based on the NDI; generating a random number N (N≥0) in the determined contention window size based on the NDI associated with the specific subframe; and performing the uplink transmission on the specific cell after sensing a channel on the specific cell at least for N slots while the channel on the specific cell is idle. If the NDI is toggled, the contention window size is reset to a minimum value, and if the NDI is not toggled, the contention window size is increased to a next higher allowed value.
