In the seven-layer OSI model of computer networking, the logical link control (LLC) data communication protocol layer is the upper sublayer of the data link layer, which is itself layer 2. The LLC sublayer provides multiplexing mechanisms that make it possible for several network protocols (IP, IPX, Decnet and Appletalk) to coexist within a multipoint network and to be transported over the same network medium. It can also provide flow control and automatic repeat request (ARQ) error management mechanisms.

The LLC sublayer acts as an interface between the media access control (MAC) sublayer and the network layer.

If you check the 4G-LTE Access Layers these are

RRC 
PDCP
RLC
MAC
PHY

Now you can assume RLC as LLC sublayer.
