Abstract: Disclosed is a method for transmitting and receiving a channel state information (CSI)-reference signal (RS) in a wireless communication system.
Specifically, the method performed by a base station may include: configuring control information indicating that an antenna port for all CSI-RS resources included in a CSI-RS resource set is same, wherein the CSI-RS resource set is used for tracking at least one of a time or a frequency; transmitting the configured control information to a user equipment (UE); and transmitting the CSI-RS to the UE through all the CSI-RS resources.
In doing so, the UE is capable of performing time/frequency tracking more precisely.

Abstract: The user equipment transmits a scheduling request by means of a scheduling request channel resource configured in the user equipment for beam recovery when uplink data is generated in the user equipment or when paging data is received therefor from a base station while the user equipment is in a discontinuous reception (DRX) mode. The user equipment receives an uplink grant in response to the scheduling request.

Abstract: The present specification provides a method for transmitting and receiving channel state information (CSI) in a wireless communication system.
More specifically, a method performed by a user equipment (UE) includes receiving a resource block from a base station based on a first spatial Quasi-Co location (QCL) related parameter related to reception of the resource block including at least one control channel, wherein when the resource block and the CSI-RS are configured on the same symbol, the first spatial QCL related parameter and a second spatial QCL related parameter configured for reception of the CSI-RS are equally configured; configuring a beam for receiving the CSI-RS based on the second spatial QCL related parameter; and receiving the CSI-RS from the base station through the configured beam.
The present specification has an effect that a UE, in which a less number of Rx chains are implemented, can receive multiple CSI-RSs.

Abstract: One disclosure in the present specification presents a method for a wireless device to receive a paging message. The method may comprise: a step of deciding a wake up signal occasion (WUSO) window for attempting to receive a wake up signal (WUS); and a step of monitoring a downlink control channel during a paging window so as to attempt to receive a paging message, if the WUS is received within the decided WUSO window. Here, the WUSO window may be decided according to a duration size and offset.

Abstract: A method for a terminal to receive a synchronization signal is disclosed in the present invention. The method receives a message including a synchronization signal block indicator indicating one or more synchronization signal block groups including at least one transmission synchronization signal block among a plurality of synchronization signal block groups grouped by the prescribed number of candidate synchronization block positions of a synchronization signal block including a primary synchronization signal, a secondary synchronization signal, and a physical broadcast channel signal, and can receive the at least one transmission synchronization signal block based on the message.

Abstract: Provided are a method for reporting a power headroom and an apparatus using the same. The apparatus computes and reports a power headroom for a physical uplink shared channel (PUSCH) that is transmitted in a first transmission period of a first band having a first subcarrier interval. The power headroom is computed on the basis of at least one second transmission interval of a second band having a second subcarrier interval which overlaps with the first transmission interval.
