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. Figure 2 The Position of the UE in the Logical Structure of the TD-LTE System LTE Phase 1 terminals may follow 3GPP R8 or R9 versions in terms of the version of air interface protocol stack. The R8 version terminal mentioned in the subsequent text refers to the LTE terminal that follows the 3GPP R8 version protocol stack; the R9 version terminal refers to the LTE terminal that follows the 3GPP R9 version protocol stack. 5 UE Classification and Power Class 5.1 Classification of UE According to the size and application range of terminals, UE can be roughly classified as follows: ——Handheld station: equipment of small size and suitable for hand-held, capable of independently supporting TD-LTE packet domain bearer services; ——Data card: equipment that cannot be used independently and needs to be connected to other equipment such as laptops or PDAs to support TD-LTE packet domain bearer services; ——Other UE: equipment not included in the above types that can be used independently or in combination with other equipment and support TD-LTE packet domain bearer services. 5.2 Power Class of UE The power class of the UE is defined in terms of maximum power output. There is only one class for UE based on the power class, as shown in Table 1.
