    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: Disclosed are a method and device for performing uplink transmission and reception in a wireless communication system. The method by which a terminal performs an uplink transmission, according to an embodiment of the present disclosure, comprises the steps of: receiving a first downlink transmission and a second downlink transmission from a base station; and transmitting, to the base station, first HARQ-ACK information associated with the first downlink transmission and second HARQ-ACK information associated with the second downlink transmission, which have been multiplexed on a PUCCH, wherein, on the basis of the first downlink transmission being a unicast SPS downlink transmission and the second downlink transmission being a multicast downlink transmission being scheduled by first DCI, a resource for the PUCCH may be based on information related to the unicast SPS downlink transmission.

    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: According to an embodiment of the present disclosure, provided is a method by which a first apparatus performs sidelink communication. The method comprises the steps of: reserving a plurality of first sidelink transmission resources for transmitting a PSCCH and a PSSCH to a second apparatus; transmitting the PSCCH and the PSSCH to the second apparatus through at least one of the plurality of first sidelink transmission resources; on the basis of a failure of the second apparatus to decode sidelink data included in the PSSCH, reselecting a plurality of second sidelink transmission resources for transmitting the sidelink data; and transmitting the sidelink data to the second apparatus on the basis of the plurality of second sidelink transmission resources.

    Abstract: A method and apparatus for resource allocation for sidelink configured grant is provided. A first wireless device receives, from a network, a cell specific Uplink (UL)-Downlink (DL) Time Division Duplex (TDD) configuration and considers that a first slot of a specific sidelink grant occurs in a logical slot determined based on a periodicity. The periodicity is determined based on a number of slots related to sidelink transmission, and the number of slots is determined based on the cell specific UL-DL TDD configuration.

    Abstract: A method and apparatus for periodic transmissions for a configured grant is provided. A first device operating in a wireless communication system transmits, to a second device, a media access control (MAC) protocol data unit (PDU) by using a first resource of a configured grant (CG) in a first period for which the first resource of the CG is associated with a HARQ process identifier (ID), and flushes a HARQ buffer associated with the HARQ process ID in a second period for which a second resource of the CG is associated with the HARQ process ID. Then, the first device ignores a retransmission resource associated with the HARQ process ID based on flushing the HARQ buffer.
