Abstract: A method of monitoring a control signal in a wireless communication system, where the method is performed by a user equipment (UE) and includes: selecting at least one control resource set (CORESET) among a plurality of CORESETs based on an overlap between physical downlink control channel (PDCCH) monitoring occasions in the plurality of CORESETs; and monitoring a PDCCH only in the selected at least one CORESET, among the plurality of CORESETs. The method also includes: based on the at least one CORESET including a first CORESET, and based on a first reference signal of the first CORESET and a second reference signal of a second CORESET being associated with a same synchronization signal/physical broadcast channel block (SSB): monitoring the PDCCH in both the first CORESET and the second CORESET.

Abstract: Systems and techniques for transmitting a physical uplink control channel (PUCCH) carrying a scheduling request (SR) in a wireless communication system. In some implementations, a method performed by a terminal includes the steps of: receiving, from a base station, a first message related to configuration of an uplink (UL) resource; receiving, from the base station, a second message related to resource configuration of a PUCCH carrying the SR; determining a resource for transmission of the PUCCH carrying the SR; and transmitting, to the base station, the PUCCH carrying the SR on the determined resource.

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.
