Abstract: A method of performing channel estimation of a physical downlink control channel (PDCCH) in a wireless communication system is disclosed. Specifically, the method performed by a user equipment (UE) includes receiving a synchronization signal block (SSB) from a base station, receiving system information (SI) from the base station based on the SSB, transmitting a physical random access channel (PRACH) preamble to the base station, receiving a response to the PRACH preamble from the base station, transmitting UE capability information related to the channel estimation to the base station, receiving information for a PDCCH monitoring duration from the base station, and performing the channel estimation based on the information for the PDCCH monitoring duration. The UE capability information includes information for a maximum number of control channel elements (CCEs) that are capable of the channel estimation per PDCCH monitoring duration.

Abstract: Provided are a method and device for monitoring a PDCCH of a terminal in a wireless communication system. The terminal receives first setting information that provides notification of a monitoring occasion for detecting a wake up signal (WUS), and performs monitoring for detecting the wake up signal in the monitoring occasion. If the wake up signal is not detected in the monitoring occasion, whether to monitor a PDCCH in the next DRX-on period is determined on the basis of second setting information that indicates the operation to be applied to the terminal when the terminal does not detect the wake up signal.

Abstract: A method for receiving a signal by a terminal in a wireless communication system according to an embodiment of the present invention can comprise a step for determining REGs, which are to be assumed that the same precoding is used, among REGs comprised in a control resource set on the basis of information relating to precoder granularity, and thus monitoring a control channel candidate. Particularly, if a part of resource blocks overlaps another resource region and particular resource blocks in the resource blocks are no longer contiguous due to the overlapping, the terminal can comprise an assumption that the same precoding is used with respect to the REGs comprised in the particular resource blocks even if the information relating to the precoder granularity corresponds to first configuration.

Abstract: According to one embodiment of the present invention, a method of receiving DCI by a UE includes receiving bundling information regarding REGs via higher layer signaling, performing blind detection for a PDCCH in a CORESET configured on a plurality of OFDM symbols, and acquiring DCI from the PDCCH. When the bundling information indicates a first value, the UE may perform bundling such that only REGs locating on a same RB and corresponding to different OFDM symbols in the CORESET, are bundled as 1 REG bundle, and when the bundling information indicates a second value, the UE may perform bundling such that the REGs locating on the same RB and corresponding to the different OFDM symbols are bundled as 1 REG bundle along with REGs locating on different RBs in the CORESET, and the UE may perform the blind detection of the PDCCH by assuming same precoding for REGs belonging to a same REG bundle as a result of REG bundling.
