    Abstract: Disclosed are a method and apparatus for performing uplink transmission in a wireless communication system. The method by which a terminal performs uplink transmission, according to an embodiment of the present disclosure, comprises the steps of: receiving, from a base station, configuration information related to at least one serving cell; receiving a unicast physical downlink shared channel (PDSCH) or a multicast PDSCH from the base station in a first serving cell of a secondary physical uplink control channel (PUCCH) group from among the at least one serving cell; and transmitting, to the base station, hybrid automatic repeat request (HARQ)-acknowledgement (ACK) information regarding the unicast PD SCH or the first multicast PDSCH, wherein on the basis that the multicast PDSCH is received from the base station in the first serving cell, the HARQ-ACK information may be transmitted to the base station by using a PUCCH resource of a second serving cell of a primary PUCCH group from among the at least one serving cell.

    Abstract: A method of receiving a physical downlink control channel (PDCCH) by a user equipment (UE) in a wireless communication system is provided. The method includes receiving, through a higher layer, (i) first information including a plurality of identifications (IDs) for a plurality of control resource sets (CORESETs) and (ii) second information related to resources of the plurality of CORESETs, determining an upper CORESET including the plurality of CORESETs based on the first information and the second information, and receiving the PDCCH through the upper CORESET. Each of the plurality of CORESETs is configured based on (i) a control channel element (CCE) supporting an aggregation level of 2n and (ii) N orthogonal frequency division multiplexing (OFDM) symbols, each of n and N being a positive integer and N being equal to or less than 3.

    Abstract: The present specification provides a method for configuring transmission or reception timing of a wireless device, and a device using the same method. A method for performing uplink transmission by a wireless device in a wireless communication system may comprise a method in which, on the basis that a first serving cell and a second serving cell are included in a particular timing advance group (TAG), and first uplink transmission timing and second uplink transmission timing are different from each other, the uplink transmission is performed on the basis of uplink transmission timing coinciding with reference uplink transmission timing applied to a downlink timing reference cell among the first uplink transmission timing and the second uplink transmission timing.

    Abstract: According to an embodiment of the present disclosure, a terminal generates and transmits a PUCCH signal for multiplexing first UCI for a scheduling request (SR) with second UCI for an HARQ-ACK on a specific time resource, wherein, on the basis that (i) the first UCI for the SR is related to a first PUCCH format, (ii) the HARQ-ACK does not exceed 2 bits; and (iii) the first UCI for the SR has the higher priority among a first priority and a second priority, the terminal can: determine a cyclic shift (CS) for the PUCCH signal; generate, on the basis of the determined CE and the first PUCCH format, the PUCCH signal for multiplexing the first UCI with the second UCI; and determine, on the basis of whether the SR is a positive SR, the PUCCH resource to which the PUCCH signal is to be mapped.
