    Abstract: Disclosed herein is a method for transmitting a wake-up signal in a wireless communication system supporting a wake-up radio (WUR) operation. The method performed by a network entity comprises transmitting a first wake-up signal for waking up a specific terminal to a specific access point (AP); transmitting a second wake-up signal to all APs within the coverage of the network entity if a response for the first wake-up signal is not received before a first timer expires; and transmitting, to a base station, a response message including control information indicating whether the specific terminal exists.

    Abstract: A disclosure of the present specification provides a method for blocking network access. The method may comprise the steps of: receiving application specific congestion control for data communication (ACDC) blocking information; driving a blocking timer when it is determined by an ACDC blocking check that a network access attempt by a first application being executed is blocked; determining the category of a second application being executed according to a network access attempt by the second application; performing an ACDC blocking check on the basis of the determined category of the second application and the received ACDC blocking information when the determined category of the second application has a higher priority than the category of the first application; and stopping the blocking timer when the network access attempt by the second application should be permitted according to the ACDC blocking check.

    Abstract: A method and apparatus are described for performing a Proximity-based Service (ProSe) by a ProSe-enabled user equipment (UE) in a cellular communication system. A connection is established with a network via a public safety band. A scheduling request (SR) signal is transmitted to the network via the public safety band. A first resource allocation is received from the network. The ProSe is performed using the first resource allocation. If a condition including a lack of channel resources is not satisfied, the SR signal carries a first identifier used for requesting resource of the public safety band. If the condition including the lack of channel resources is satisfied, the SR signal carries a second identifier used for requesting resource of a non-public safety band.

    Abstract: A method and apparatus are described for managing a communication connection by a User Equipment (UE) in a wireless communication system. In one embodiment, a first message is transmitted for requesting a Radio Resource Control (RRC) connection. The first message includes a cause of the request related with a Proximity-based Service (ProSe), and an identifier randomly generated for the communication connection by the UE and set to be effective for a predetermined time. The communication connection is established via a network path. A second message is received from a ProSe server. The second message indicates whether the communication connection is out of proximity range or not. When the second message indicates that the communication connection is out of the proximity range, a third message for requesting one of a proximity range extension and a communication connection release is transmitted to the ProSe server.
