    摘要： An access control technology in a next generation mobile communication network is disclosed. More specifically, disclosed is a technology for controlling an access control operation of a terminal through an integrated category by various methods and layers. One embodiment provides a method by which a terminal performs integrated access control, comprising the steps of: receiving, from a base station, system information including information for access control; indicating access category information from an NAS layer to an AS layer of the terminal when an access attempt is triggered; confirming whether access barring parameter information is included in the system information; and controlling an access barring check operation in the AS layer by using at least one of the access category information and the access barring parameter information.

    摘要： Provided are methods and apparatuses for transmitting HARQ feedback information for sidelink transmission. In particular, a method of a transmitter user equipment (Tx UE) is provided for transmitting the HARQ feedback information for the sidelink transmission. The method may include: receiving, from the base station, resource allocation information on a physical uplink control channel (PUCCH) for transmitting, to the base station, the HARQ feedback information for the sidelink transmission to a receiver user equipment (Rx UE); generating the HARQ feedback information based on a physical sidelink feedback channel (PSFCH) for the sidelink transmission received from the Rx UE; and transmitting the HARQ feedback information over the PUCCH based on the resource allocation information to the base station.

    摘要： Provided are methods for transmission of a sounding reference signal (SRS) being independent of or separated from an uplink channel. The method may include receiving UE-specific configuration information including an uplink reference signal identity from the first transmission/reception point, determining the second transmission/reception point indicated by the uplink reference signal identity included in the received UE-specific configuration information as an uplink channel reception entity, transmitting the uplink channel to the determined second transmission/reception point, using the uplink reference signal identity, generating an SRS, using the physical cell identity of the first transmission/reception point, determining the first transmission/reception point as an SRS reception entity, and transmitting the generated SRS to the determined first transmission/reception point indicated by the physical cell identity.
