33、Bs). For the UTRA evolution requirement specifications for other types of base stations are needed as well to take into account different use scenarios and radio environments. In this technical report, base station classification is described and requirements for each base station class are derived.
34、 ETSI 3GPP TR 25.952 version 5.2.0 Release 5 7 ETSI TR 125 952 V5.2.0 (2003-03) 5 System scenarios This section describes the system scenarios for UTRA operation that are considered when defining base station classes. It also includes typical radio parameters that are used to derive requirements. 5.
35、1 Indoor Environment 5.1 .I Path Loss Model The indoor path loss model expressed in dB is in the following form, which is derived from the COST 23 1 indoor model: L = 37 + 20 Loglo(R) + C kwi L, + 18.3 n(n+2)(n+1)-o.46) where: R = transmitter-receiver separation given in metres k, = number of penetr
36、ated walls of type i Lwi = loss of wall type i n = number of penetrated floors Two types of internal walls are considered. Light internal walls with a loss factor of 3.4 dB and regular internal walls with a loss factor of 6.9 dB. If internal walls are not modelled individually, the indoor path loss
37、model is represented by the following formula: L = 37 + 30 Loglo) + 18.3 n(n+2)(n+1)-0.46) where: R = transmitter-receiver separation given in metres; n = number of penetrated floors Slow fading deviation in pico environment is assumed to be 6 dB. 5.2 Mixed Indoor - Outdoor Environment 5.2.1 Propaga
38、tion 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. Attenuation from outdoors to indoors is sketched in Figure 5.1 below. In the figure star denotes receiving object and circle transmitting object. Receivers are pro
39、jected to virtual positions. Attenuation is calculated using micro propagation model between transmitter and each virtual position. Indoor attenuation is calculated between virtual transmitters and the receiver. Finally, lowest pathloss is selected for further calculations. Only one floor is conside
40、red. The total pathloss between outdoor transmitter and indoor receiver is calculated as L = L + Low + C k, Lwi + a * R , where: Lmicro = Micro cell pathloss according UMTS30.03 Outdoor to Indoor and Pedestrian Test Environment pathloss model Low = outdoor wall penetration loss dB ETSI 3GPP TR 25.95

45、distance loss including antenna gain measured between antenna connectors. 5.3.1 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 cei
46、ling, on wall or some other exposed 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 defiied in 4 as: Path loss dB = 38.25 + 20 loglO(d m) Taking into account O dBi antenna gain for Local area BS and UE and a body loss of 1
47、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. The assumed MCL values are summarised in Table 5.2. Table 5.2: Minimum Coupling Losses 5.4 Propagation conditions for local area base stations The demodulation of D
48、CH in multipath fading conditions in TS 25.105 considers three different test environments: Case 1 : Typical indoor environment delay spread, low terminal speed Case 2: Large delay spread (12 us), low terminal speed Case 3: Typical vehicular environment delay spread, high terminal speed (120 km/h) T
49、he local area BS is intended for small cells as can be usually found in indoor environments or outdoor hot spot areas. The large delay spread in Case 2 and the high terminal speed in Case 3 are not typical for these scenarios. Therefore, requirements defined for Case 2 and Case 3 shall not be applied to the local area BS. The Case 1 propagation condition shall apply for both the local area and wide area BS. 6 Base station classes This section describes how the base station classes are defined. 6.1 Base station class criteria Different sets
