Abstract: The present disclosure suggests a method for adjusting the size of a contention window of a base station/terminal. The method comprises transmitting a physical downlink shared channel (PDSCH) to a user equipment (UE) through a frequency bandwidth, receiving an acknowledgement/negative-acknowledgement (ACK/NACK) signal for the PDSCH from the UE, and adjusting the contention window based on the ACK/NACK signal, wherein based on the frequency bandwidth overlapping with a plurality of frequency bands, the BS adjusts the contention window for each of the plurality of frequency bands based on the ACK/NACK signal.

Abstract: Provided are a method for transmitting uplink control information (UCI) of a terminal in a wireless communication system and the UE using the method. The method includes determining a number of coded symbols for the UCI transmission and transmitting the UCI on a physical uplink shared channel (PUSCH) based on the number of coded symbols. The number of coded symbols is determined among a first value based on a payload size of the UCI and an offset value and a second value based on a radio resource control (RRC) signal.

Abstract: A method for transmitting multiple uplink control information (UCI) on a physical uplink control channel (PUCCH) in a wireless communication system is disclosed. More specifically, the method performed by a user equipment (UE) includes receiving, from a base station, first control information related to the PUCCH for transmitting the multiple UCI; determining a first parameter representing a number of coded bits for the multiple UCI based on the first control information, wherein the multiple UCI includes channel state information (CSI) including at least one of a first part or a second part; determining a size of the first part based on the first parameter and second control information related to the size determination of the first part; and transmitting, to the base station, the multiple UCI on the PUCCH.
