36、. 4 General Current TSG RAN WG4 specifications have been done according to the requirements for the general purpose base stations (NodeBs) applications. For the UTRA evolution requirement specifications for other types of base stations are needed as well to take into account different use scenarios
37、and radio environments. In this technical report, base station classification is described and requirements for each base station class are derived. 5 System scenarios This section describes the system scenarios for UTRA operation that are considered when defining base station classes. It also inclu
38、des typical radio parameters that are used to derive requirements. 5.1 Indoor Environment 5.1.1 Path Loss Model The indoor path loss model expressed in dB is in the following form, which is derived from the COST 231 indoor model: L = 37 + 20 Log10I + kwiLwi+ 18.3 n(n+2)/(n+1)-0.46) where: ETSI ETSI
39、TR 125 951 V14.0.0 (2017-04)83GPP TR 25.951 version 14.0.0 Release 14R transmitter-receiver separation given in metres kwinumber of penetrated walls of type i Lwiloss of wall type i n number of penetrated floors Two types of internal walls are considered. Light internal walls with a loss factor of 3
40、.4 dB and regular internal walls with a loss factor of 6.9 dB. If internal walls are not modelled individually, the indoor path loss model is represented by the following formula: L = 37 + 30 Log10I + 18.3 n (n+2)/(n+1)-0.46) where: R transmitter-receiver separation given in metres; n number of pene
41、trated floors Slow fading deviation in pico environment is assumed to be 6 dB. 5.2 Mixed Indoor Outdoor Environment 5.2.1 Propagation Model Distance attenuation inside a building is a pico cell model as defined in Chapter 5.1.1. In outdoors UMTS30.03 model is used 5. Attenuation from outdoors to ind
42、oors is sketched in Figure 5.1 below. In figure star denotes receiving object and circle transmitting object. Receivers are projected to virtual positions. Attenuation is calculated using micro propagation model between transmitter and each virtual position. Indoor attenuation is calculated between
43、virtual transmitters and the receiver. Finally, lowest pathloss is selected for further calculations. Only one floor is considered. The total pathloss between outdoor transmitter and indoor receiver is calculated as L = Lmicro+ LOW+ kwiLwi+ a * R , where: Lmicro Micro cell pathloss according UMTS30.

48、 antenna gain measured between antenna connectors. MCL for Local Area scenario The minimum coupling loss between Ues is independent of the scenario, therefore the same minimum coupling loss is assumed for all environments. Local area BSs are usually mounted under the ceiling, on wall or some other e
49、xposed position. In 4 chapter 4.1.1.2 a minimal separation of 2 metres between UE and indoor BS is assumed. Free space path loss is defined in 4 as: Path loss dB = 38.25 + 20 log10(d m) Taking into account 0 dBi antenna gain for Local area BS and UE and a body loss of 1 dB at the terminal, a MCL of 45.27 dB is obtained. The additional 2 dB cable loss at the BS as proposed in TR 25.942 is not considered.
