Method and apparatus for performing and reporting measurements by user equipment configured with multiple carriers in mobile communication systems

說(shuō)明書
The LTE system refers to a system that a communication service provider uses to provide communication services via a licensed band frequency assigned from a corresponding organization. However, in order to meet the rapid increase in the demand for traffic, a discussion is made on the LTE technology to use in an unlicensed band used for Wireless LAN, Bluetooth, etc., which is called Licensed-Assisted Access (LAA). When the CA technology is applied to the LAA, a scenario will be considered where a PCell uses a licensed band frequency and SCells use an unlicensed band frequency by using the LAA.
Unlike licensed bands, the unlicensed band does not have a specific duplex mode. Therefore, the unlicensed band can be set in different modes according to countries/regions. Since unlicensed bands are already used by existing heterogeneous systems, such as wireless LAN, Bluetooth, etc., they can have serious interference issues, compared with licensed bands. Therefore, when measurement is configured to use unlicensed bands, the potential issues need to be considered, unlike the licensed bands.
Hereinafter, the fifth embodiment of the present disclosure is described in detail with reference to the accompanying drawings.
Hereinafter, a technology to provide dual connectivity in a wireless communication system is described in detail.
In the following description, terms for identifying access nodes and terms for indicating: network entities; messages; interfaces between network entities; various identifications; etc., are used for the sake of convenience. Therefore, it should be understood that the present disclosure is limited by the terms and can also employ any other terms to equivalently indicate the same components corresponding thereto.
