llustrates the visualization of the EIRP, EIS, and TRP definitions. The main BS RF performance specifications of the LTE and NR in FR1 and FR2 have been summarized and compared in Table 5.4. The RF specifications in FR1 are based on LTE specifications with the maximum channel bandwidth of 100 MHz. In FR2, the NR radio specifications support wider bands, lower latency, and faster response with maximum Base station type BS type 1-C BS type 1-H BS type 1-0/2-O (equivalent to legacy BS) (equivalent to AAS BS in LTE Rel-13) (new BS types for NR) Frequency range FR1/FR2 Antenna Transceiver unit 1 Transceiver unit 1 Transceiver unit 1 Transceiver unit 2 Transceiver unit 2 Transceiver unit 2 Base station Antenna connector configuration (reference point Antenna for conducted Antenna requirements) Transceiver unit M connector Transceiver unit M Transceiver unit M Coaxial cable TAB connector (Reference point for conducted requirements and partial OTA requirements) Figure 5.6 NR base station configurations 5,29]. 670 Chapter 5 Table 5.3: Output power per base station class and type (dBm) [5,14].
