Problems solved by technology

[0008] Also, after the relay UE establishes a connection with the remote UE, it may be necessary to release the connection
For example, there are situations where the quality of service provided by the relay UE deteriorates or the relay UE needs to provide relay services for different UEs preferentially

Embodiment Construction

[0044] figure 1 A wireless communication system to which the present invention is applied is shown. The wireless communication system may also be referred to as an Evolved UMTS Terrestrial Radio Access Network (E-UTRAN) or a Long Term Evolution (LTE) / LTE-A system.

[0045] The E-UTRAN includes at least one base station (BS) 20 that provides a user equipment (UE) 10 with a control plane and a user plane. The UE 10 may be fixed or mobile, and may be referred to by another term, such as a mobile station (MS), user terminal (UT), subscriber station (SS), mobile terminal (MT), wireless device, and the like. BS 20 is typically a fixed station that communicates with UE 10 and may be referred to by another term such as evolved Node B (eNB), base transceiver system (BTS), access point, and so on.

[0046] The BSs 20 are connected to each other by means of the X2 interface. BS 20 is also connected to Evolved Packet Core (EPC) 30 by means of S1 interface, more specifically, to Mobilit...

Abstract

Provided are a delinking method implemented by a remote UE in a wireless communication system, and a device using said method. The method is characterized by: receiving a disconnect message for disconnecting a link between a relay UE and the remote UE; disconnecting the link on the basis of the disconnect message; and not attempting to establish a link between the remote UE and the relay UE in a UE-specified time section.

Description

technical field [0001] The present invention relates to wireless communication, and more particularly, to a method for releasing a link performed by a user equipment (UE) in a wireless communication system and a UE using the method. Background technique [0002] In the International Telecommunication Union Radiocommunication Sector (ITU-R), standardization work for advanced International Mobile Telecommunications (IMT), ie, next-generation mobile communication systems from the third generation onwards, is in progress. IMT-Advanced sets its target to support Internet Protocol (IP) based multimedia services at a data transfer rate of 1 Gbps in stop and slow moving states and 100 Mps in fast moving states. [0003] For example, the 3rd Generation Partnership Project (3GPP) is a system standard meeting the requirements of IMT-Advanced and is based on the Orthogonal Frequency Division Multiple Access (OFDMA) / Single Carrier Frequency Division Multiple Access (SC-FDMA) transmission...
