Abstract: A method and apparatus for measuring a reference signal strength indication (RSSI) in a wireless communication system is provided. When a semi-static downlink/uplink (DL/UL) configuration or a dynamic slot formation indication (SFI) is not received from a network, a user equipment (UE) determines RSSI measurement resources based on detected synchronization signal (SS)/physical broadcast channel (PBCH) block, and measuring the RSSI based on the RSSI measurement resources.

Abstract: The present disclosure provides a method for performing channel estimation using a demodulation reference signal (DMRS) in a wireless communication system. More specifically, the method, which is performed by a base station, comprises: when a collision between a DMRS symbol and a synchronization signal block (SSB) occurs, shifting a resource block (RB) of the DMRS symbol where the collision occurs, and all REs bundled with the RE of the DMRS symbol where the collision occurs; transmitting information on the shifted REs to a terminal; and transmitting the DMRS to the terminal on the shifted REs.

Abstract: Disclosed herein is a method for transmitting a demodulation reference signal for an uplink control signal in a wireless communication system.
Specifically, the method performed by a terminal includes: generating a low peak to average power ratio (PAPR) sequence based on a length-6 sequence; generating a sequence used for the demodulation reference signal based on the low PAPR sequence; and transmitting, to a base station, the demodulation reference signal based on the sequence used for the demodulation reference signal, in which the length-6 sequence has an 8-phase shift keying (PSK) symbol as each element of a sequence.

Abstract: Disclosed herein is a method for receiving remaining minimum system information (RMSI) by a user equipment (UE) in a wireless communication system. The method includes receiving an synchronization signal (SS)/physical broadcast channel (PBCH) block including an SS and a PBCH in a half-frame, obtaining, via the PBCH, information related to a monitoring window for receiving a physical downlink control channel (PDCCH) for the RMSI, receiving the PDCCH within the monitoring window, and receiving the RMSI based on the PDCCH, wherein monitoring windows related to SS/PBCH blocks having consecutive indexes among SS/PBCH blocks receivable in the half-frame are at least partially overlapped each other.
