Embodiment Construction

[0038] figure 1 The wireless communication system to which the present invention is applied is illustrated. 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.

[0039] E-UTRAN includes at least one base station (BS) 20 that provides a control plane and a user plane to a user equipment (UE) 10. The UE 10 may be fixed or mobile, and may be called another term such as a mobile station (MS), a user terminal (UT), a user station (SS), a mobile terminal (MT), a wireless device, and so on. The BS20 is generally a fixed station that communicates with the UE, and may be called another term, such as an evolved node B (eNB), a basic transceiver system (BTS), an access point, and so on.

[0040] BS20 is interconnected by means of the X2 interface. The BS 20 is also connected to the evolved packet core (EPC) 30 by means of the S1 interface, more specifically, connected to the mobi...

Abstract

A method of a cell reselection performed by a user equipment (UE) in a wireless communication system, the method comprising: receiving supreme priority information from a target cell, the supreme priority information indicating whether a deprioritization is applied; applying the supreme priority information, if the supreme priority information indicates that the deprioritization is applied; and performing a cell reselection based on the applied deprioritization.

Description

Technical field [0001] The present invention relates to wireless communication, and more specifically, to a method and device for cell reselection by applying the highest priority in a wireless communication system. Background technique [0002] The Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) is an improved form of the Universal Mobile Telecommunications System (UMTS) and was introduced as 3GPP release 8. 3GPP LTE uses Orthogonal Frequency Division Multiplexing (OFDMA) in the downlink, and Single carrier frequency division multiple access (SC-FDMA) is used in the uplink. 3GPP LTE uses multiple input multiple output (MIMO) with up to four antennas. In recent years, discussions on 3GPP LTE-Advanced (LTE-A), which is an evolution of 3GPP LTE, are ongoing. [0003] A micro cell, a femto cell, a pico cell, etc. having a small service area can be installed in a specific location of a macro cell having a wide coverage. [0004] Due to the movement of User Equipm...
