Abstract: The present disclosure discloses a method of receiving a downlink channel by a user equipment (UE) in a wireless communication system. Particularly, the method includes receiving a synchronization signal block (SSB) including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH), obtaining information about the position of a downlink bandwidth from the PBCH, and receiving the downlink channel within the downlink bandwidth determined on the basis of the obtained information about the position of the downlink bandwidth. The information about the position of the downlink bandwidth is an offset from the position of a bandwidth of the SSB to the position of the downlink bandwidth.

Abstract: Disclosed are a method for transmitting/receiving an uplink signal between a base station and a terminal, and a device for supporting the same. More specifically, disclosed are a method for transmitting/receiving a signal between a terminal and a base station for the coexistence of terminals to which different transmission time intervals (TTIs) are applied when the terminals to which the different TTIs are applied send an uplink signal on the same resource, and a device for supporting the same.

Abstract: The present disclosure provides a method for transmitting a random access channel (RACH) by a UE in a wireless communication system. Particularly, the method includes receiving information about actually transmitted synchronization signal blocks (SBBs) and RACH configuration information about RACH resources and transmitting a RACH in at least one RACH resource among RACH resources mapped to actually transmitted SSBs on the basis of the information about actually transmitted SSBs and the RACH configuration information, wherein the actually transmitted SSBs are repeatedly mapped to RACH resources by a positive integer multiple of the number of the actually transmitted SSBs in a RACH configuration period based on the RACH configuration information.

Abstract: The present invention provides a method for a terminal and a base station including multiple TRPs to transmit/receive signals, and a device therefor. More particularly, the present invention provides a method whereby, if one or more base stations are present, and multiple TRPs are present in each of the base stations, a TRP for signal transmission/reception by a terminal and a base station is selected by using an uplink signal transmitted by the terminal, and a signal is transmitted/received based on the TRP. The present invention also provides a device for the method.

Abstract: In the present invention, when a UE transmits a random access preamble, the UE maintains a power ramping counter used for determination of a transmission power equally to a value of previous transmission without incrementing the power ramping counter if a target synchronization signal block is changed differently from a previous random access preamble transmission.

Abstract: Discloses are a method for a terminal for transmitting an uplink signal to a base station and an apparatus supporting the method in a licensed assisted access (LAA) system in which a base station or a terminal transmits listen-before-talk (LBT)-based signals. Specifically, disclosed are a method for a terminal transmitting an uplink signal by executing a particular LBT action and an apparatus supporting the method if the uplink signal is transmitted by the terminal by sharing a maximum channel occupancy time (MCOT) with a base station.

Abstract: A user equipment (UE) receives UE group information indicating a first UE group to which the UE belongs, and transmits uplink (UL) data and a demodulation reference signal (DM-RS), which is for demodulating the UL data, on the basis of the UE group information. The DM-RS is transmitted by means of a first uplink demodulation reference signal (UL DM-RS) resource, which corresponds to the first UE group to which the UE belongs, among a plurality of UL DM-RS resources respectively corresponding to one or more UE groups.

Abstract: A user equipment attempts to decode decoding candidates and detects a physical downlink control channel (PDCCH) within time symbols from time symbol #0 to time symbol #N−1 for downlink control channel transmission in a transmission time interval (TTI). The user equipment receives downlink data on the basis of downlink control information carried by the PDCCH. Each of time symbol #0 to time symbol #N−1 includes a floor(X/N) number of decoding candidates. N is a maximum number of time symbols available for downlink control channel transmission in the TTI and is equal to or smaller than N, and X is a maximum number of decoding candidates for each TTI.

Abstract: The present invention discloses a method for a user equipment to receive a PDCCH (Physical Downlink Control Channel) for RMSI (Remaining Minimum System Information). The method comprises: receiving an SS/PBCH block containing an SS (Synchronization Signal) and a PBCH (Physical Broadcasting Channel); obtaining information related to a CORESET (Control resource set) for the PDCCH; and receiving the PDCCH within the CORESET based on the information. The information includes an offset between a frequency position of the SS/PBCH block related to the COPRESET and a frequency position of the CORESET. Values of the offset are defined based on subcarrier spacing of the SS/PBCH block and a minimum channel bandwidth.
