Abstract: A method for transmitting a sounding reference signal (SRS) by a by a user equipment (UE) includes: receiving, from a base station, first information on a number of SRS symbols configured for one slot and second information on a number of repetitions of symbols configured for transmission of an SRS; determining whether the number of repetitions is greater than the number of the SRS symbols; when the number of repetitions is greater than the number of the SRS symbols, determining the number of repetitions of the symbols by a value identical to the number of the SRS symbols; and transmitting the SRS based on the determined number of repetitions. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station, or a network.

Abstract: According to one embodiment of the present disclosure, a method and an apparatus for allowing a user equipment (UE) to effectively monitor a control resource set (CORESET) in order to read remaining minimum system information (RMSI) in a wireless communication system are provided. The UE receives a media access control (MAC) control element (CE) indication, performs a random access channel (RACH) procedure, determines a transmission configuration indicator (TCI) state of CORESET 0 on the basis of the most recent of either the MAC CE indication or the RACH procedure, and monitors CORESET 0 on the basis of the determined TCI state.

Abstract: Provided are a method for reporting a power headroom and an apparatus using the same. The apparatus computes and reports a power headroom for a physical uplink shared channel (PUSCH) that is transmitted in a first transmission period of a first band having a first subcarrier interval. The power headroom is computed on the basis of at least one second transmission interval of a second band having a second subcarrier interval which overlaps with the first transmission interval.

Abstract: A method is provided for reporting feedback information of Multicast-Broadcast Single-Frequency Network (MBSFN) transmission by a user equipment in a wireless communication system. The user equipment receives configuration information for feedback information of the MBSFN transmission when the user equipment receives signals from a plurality of base stations based on the MBSFN transmission, and transmits the feedback information measured in a resource region according to the configuration information. The user equipment receives a common reference signal (CRS) of an antenna port 0 of an interference cell from the interference cell in an MBSFN area, and the feedback information is measured in the resource region considering a position of a symbol allocated the CRS of the antenna port 0 of the interference cell.
