4 Overview
Figure 1 Logical Structure Diagram of TD-LTE Terminal Equipment
TD-LTE terminal equipment, also known as user equipment (UE), may be classified into various types based on their purposes and functions. The terminal shall provide corresponding compatibility interfaces according to the different connected equipment, such as the air interface and USB interface between the TD-LTE terminal and the TD-LTE network equipment. Terminal equipment shall include ME capable of sending and receiving wireless signals, baseband processing and running high-level applications, and a detachable smart card USIM capable of saving data, programs and secure identification. ME and USIM shall be connected by standard Cu interface. ME can be further divided into smaller unit equipment logically, i.e. the MT responsible for wireless reception and transmission and related functions and the TE responsible for running end-to-end high-level applications. The MT and the TE can be connected through various physical means (wired or wireless).
In the TD-LTE logical structure diagram shown in Figure 2, the TE is connected to the base station equipment system through the TD-LTE air interface (Uu interface), and communicates with the core network (CN) through the base station equipment system, thereby completing the entire end-to-end service connection.
