Abstract: One disclosure of the present specification provides a communication method, for handling a network error, performed by a terminal. The terminal can receive information relating to a second public land mobile network (PLMN) to which the terminal is subscribed from a base station in a first PLMN. The terminal can be connected to the first PLMN by means of the base station in the first PLMN on the basis of the information relating to the second PLMN. Information notifying of an error which has occurred in the second PLMN can be displayed on a display of the terminal.

Abstract: Disclosed as a method of controlling access to a network in a wireless communication system and an apparatus therefor. Specifically, a method of performing access to a network by a user equipment (UE) in a wireless communication system may include receiving first information on whether a specific access identity is valid in a specific public land mobile network (PLMN) from the network, when the UE selects a PLMN and attempts access, determining whether the specific access identity is valid in the PLMN selected by the UE based on the first information, selecting an access identity based on the determination, and performing an access control procedure based on the selected access identity.

Abstract: In a wireless communication system, a user equipment (relay UE) can request to connect to a network to transfer data to another user equipment (remote UE). Before requesting the connection, the relay UE can perform access control for determining whether an access attempt to the network is allowed. The relay UE can perform the access control by using an access class of the remote UE.

Abstract: A method for transmitting an uplink signal by a user equipment (UE). The method includes receiving an uplink grant including a new data indicator (NDI) on a physical downlink control channel (PDCCH) from a network, determining whether the PDCCH is not addressed to a temporary cell identifier, determining whether the NDI has been toggled when the PDCCH is not addressed to the temporary cell identifier, and transmitting a new data to the network when the NDI has been toggled.
