24、duction This Annex contains the methodology for modelling and simulation of IMT networks for use in sharing and compatibility studies. It describes the appropriate IMT models to be used for sharing and compatibility studies between IMT and other radio systems in various frequency bands. Definitions

25、and basic concepts of IMT networks are described in 2 to facilitate selection of the appropriate IMT model. Section 2 also provides information on technical elements such as output power and antenna pattern, antenna height and environment associated with deployment scenarios, density and distributio

26、n of IMT stations and information on propagation models for paths between IMT base stations and mobile stations. It contains detailed IMT system parameters to be considered in such modelling and their implementation in the simulations as described in 3 through 6. Specifically, 3 contains simulation

27、steps for modelling total emissions generated by an IMT network (in the case IMT is the interfering system) as well as modelling the impact on the IMT network (in the case IMT is the interfered-with system). Subsequently, considerations in calculating the aggregate effect of potential interference g

28、enerated by an IMT system is described in 7. Furthermore, in order to emphasize the importance of realistically modelling IMT systems in sharing and compatibility scenarios, 8 describes means to compare the implementation of modelling of IMT system through comparing interim results related to perfor

29、mance and operation of the IMT system. 2 Definitions and basic concepts 2.1 Usage scenarios IMT-Advanced is the most widely accepted radio air-interface for the provision of mobile broadband (MBB). The IMT-2020 radio interface, in addition to supporting the enhanced mobile broadband (eMBB) use case,

30、 will support emerging use cases with a variety of applications such as massive machine-type communications (mMTC) and ultra-reliable and low latency communications (URLLC). The methodology is applicable for all the above scenarios and focuses mostly on MBB and eMBB scenarios, which are the dominant

31、 usage scenarios in sharing and compatibility studies. Mobile broadband and enhanced mobile broadband are the result of applying more spectrally efficient technologies into larger amounts of spectrum, enabling higher data rate services. Massive machine-type communication is about connectivity for la

32、rge numbers of low-cost and low-energy consumption devices in the context of the Internet of Things (IoT). Ultra-reliable and low latency communications are envisioned to enable real-time control and automation of dynamic processes in various fields, such as industrial process automation and manufac

33、turing, energy distribution, intelligent transport systems and requires communication with very high reliability and availability, as well as very low end-to-end latency. Device-to-device (D2D) and machine-to-machine (M2M) communications may be used for mMTC and URLLC applications. In D2D/M2M commun

34、ications, mobile stations initiate communications with base stations using their control channel. User data traffic is delivered by data channel directly among mobile stations. In this scenario, mobile stations are located within a cell area provided by a base station. Rec. ITU-R M.2101-0 5 2.2 Depl

35、oyment scenarios From a deployment perspective, it is worthwhile categorizing IMT-Advanced and IMT-2020 radio access networks as either outdoor or indoor and as seamless wide area coverage or small area coverage. Table 1 provides a high level description of IMT deployments. Categories 1 and 2 are th

36、e same as the existing configuration of IMT networks with seamless macro coverage. Categories 3 and 4 for coverage of small areas could be operated independently or combined with categories 1 and 2.

38、rea Coverage (Omni, Sector Antenna, Beam forming antenna) Furthermore, radio access networks may be classified to each deployment scenario by considering the following aspects: a) environments (Rural / Suburban / Urban / Indoor); b) seamless wide area coverage / Small area coverage. Six deployment s

39、cenarios are defined in Table 2 as combinations of the above aspects a) and b). Three deployment scenarios of macro rural, macro suburban and macro urban are the same as the existing configuration of IMT networks with seamless macro coverage. The other three deployment scenarios of micro suburban, m

40、icro urban and indoor are deployed to cover small areas. The latter three deployment scenarios could be operated independently in some cases, whereas it could be often the case that they are operated combined with the former three deployment scenarios. The classification of deployment scenarios in T

41、able 2 is applicable to relevant IMT models and associated propagation environments to apply appropriate IMT modelling for sharing studies.

ITU-R M.2101-0 An illustration of possible scenarios is provided in Fig. 1 and further described below. FIGURE 1 Example deployment scenarios M . 2 1 0 1 - 0 1M a c r o s e l lM i c r o s u b u r b

Base station antennas are typically deployed at the top of tower. (2) M

44、acro suburban The macro suburban scenario focuses on seamless coverage of suburban areas (mainly residential) as well as rural towns with low-rise buildings, but not including the unpopulated areas between them. Base station antennas are typically deployed on tower/rooftop and users can be either ou

45、tdoors and indoors. (3) Macro urban The macro urban scenario focuses on multi-story buildings with base station antennas typically at or above the level of the roofline. Base station power may vary depending on local deployment and coverage needs. Users can either be outdoors or indoors. Repeaters f

46、or indoor coverage, if any, are considered equivalent to, and therefore treated as, user equipment (UEs). (4) Micro suburban The micro suburban scenario focuses on capacity enhancement in small community areas with low-rise buildings in suburban areas. Base station antennas are typically deployed mo

47、unted on poles. Users can either be outdoors or indoors. Repeaters for indoor coverage, if any, are considered equivalent to, and therefore treated as, UEs. (5) Micro urban The micro urban scenario focuses on multi-story buildings with base station antennas below the roofline. Base station antennas

48、are typically deployed as single sector antennas or beam forming antennas with low output power. The deployment scenario has an environment that blocking and/or multiple diffractions/scattering are dominant near the antennas, such as street micro cell and small hot spot, from the viewpoint of propag

49、ation effects. Users can either be outdoors and indoors. Rec. ITU-R M.2101-0 7 (6) Indoor The indoor scenario occurs most often in urban or suburban environments. Base stations and users are indoors. 2.3 Transmit power control Studies to assess the impact of an entire IMT network should take into account the varying nature of an IMT network, in particular power control. For uplink, some device types (e.g. low power devices for MTC applications) may operate without any power control while for other types (e.g. enhanced mobile broadband devices) power control wi
