Abstract:
A method and a user equipment (UE) are described for transmitting power headroom (PH) information. The UE generates PH information, and transmits the PH information to a base station. The PH information includes a first field including a plurality of indicators, each of the plurality of indicators indicating the presence of a second field indicating a PH level of a corresponding secondary cell (SCell). The PH information further includes a type-1 PH field and a type-2 PH field for a primary cell (PCell). Each of the plurality of indicators is set to 0 or 1. An indicator, which has been set to 1, indicates that the second field exists for the corresponding SCell, and an indicator, which has been set to 0, indicates that the second field does not exist for the corresponding SCell.

Disclosed are a method and device for transmitting and receiving group-common information in a wireless communication system. A method for a terminal in a wireless communication system may comprise: receiving, from a network, configuration information about one or more CSI-RS resource sets for a TRS; receiving group-common DCI from the network on the basis of a specific CSI-RS resource set among the one or more CSI-RS resource sets and a group-common identifier; and receiving, from the network, a group-common PDSCH scheduled by the group-common DCI. Here, the one or more CSI-RS resource sets may be configured for one of one or more cell groups and/or one or more group-common identifiers including the group-common identifier.
Abstract:
A method and apparatus for transmitting sidelink control information in a wireless communication system is provided. A wireless device determines that a sidelink (SL) resource has not been reserved within a time period related to transmission of sidelink control information (SCI), and triggers SL resource reservation for transmission of the SCI.

A method of performing uplink transmission in a wireless communication system, according to one embodiment of the present disclosure, may comprise the steps of. receiving multicast PDSCHs on the basis of a plurality of G-RNTIs; receiving DCI for scheduling a PUSCH, wherein the DCI includes information on a T-DAI value for a HARQ-ACK codebook for a multicast; applying the T-DAI value per G-RNTI with respect to the plurality of G-RNTIs so as to determine a plurality of HARQ-ACK codebooks for the multicast PDSCHs; and transmitting HARQ-ACK information determined by concatenating the plurality of HARQ-ACK codebooks.
Abstract:
Disclosed are a method and apparatus for performing communication in a wireless communication system. A method by which a terminal performs communication, according to an embodiment of the present disclosure, comprises the steps of: receiving, from a base station, a PDCCH in at least one PDCCH MO corresponding to at least one SSB index in a specific window; and receiving, from the base station, data associated with a specific G-RNTI on the basis of the PDCCH, wherein the at least one SSB index may be an index of an SSB corresponding to the specific G-RNTI from among a plurality of SSBS configured by the base station.
Abstract:
A method and a device for transmitting or receiving HARQ-ACK information in a wireless communication system are disclosed. The method for transmitting HARQ-ACK information according to an embodiment of the present disclosure may comprise the steps of: receiving, from a base station, first physical uplink control channel (PUCCH) configuration information related to an ACK/negative ACK (NACK)-based HARQ-ACK report for a multicast physical downlink shared channel (PDSCH) or second PUCCH configuration information related to a NACK only-based HARQ-ACK report for the multicast PDSCH, for each of one or more uplink bandwidth parts (BWPs) configured for a terminal; receiving, from the base station, downlink control information (DCI) for scheduling of a first multicast PDSCH; receiving the first multicast PDSCH from the base station on the basis of the DCI; and transmitting first HARQ-ACK information for the first multicast PDSCH to the base station on a first PUCCH.
Abstract:
The present disclosure provides a method by which a terminal receives a physical downlink control channel (PDCCH) in a wireless communication system. In particular, the method comprises: receiving a parameter related to PDCCH monitoring adaptation through a higher layer; receiving information indicating an operation related to the PDCCH monitoring adaptation, on the basis of the parameter; and receiving the PDCCH on the basis of the information, wherein the receiving of the PDCCH comprises monitoring the PDCCH through a common search space (CSS) set on the basis of an RNTI different from a radio network temporary identifier (C-RNTI) during a time interval associated with the information.
Abstract:
A method and apparatus for dynamic configuration of a maximum number of sidelink retransmissions for a data unit in a wireless communication system is provided. A first wireless device in sidelink receives, from a network, information related to a first retransmission number for a first logical channel and a second retransmission number for a second logical channel. The first wireless device determines a retransmission number of a data unit among the first retransmission number and the second retransmission number, and performs sidelink transmission of the data unit to a second wireless device based on the retransmission number of the data unit.
