35、tem scenarios This clause describes the system scenarios for LTE operation that are considered when defining LTE Pico BS class. It also includes typical radio parameters that are used to derive requirements. 5.1 Pico NodeB class Pico Base Stations are characterised by requirements derived from Pico
36、Cell scenarios with a BS to UE minimum coupling loss (MCL) equal to 45 dB. Note: This value was derived from 2GHz Band. Editors Note: The impact on the MCL values due to different frequency bands is for FFS. 5.2 Radio scenario Pico radio scenarios have these characteristics: relatively large coverag
37、e, dense user population, easy and flexible installation, and large capacity data service. Pico BS is typically used in indoor offices, indoor hotspots, outdoor hotspots, or dense blocks, and is located on walls, ceilings, or masts. 5.3 Simulation assumptions 5.3.1 Deployment modelling 5.3.1.1 Pico
38、deployment This modelling is referenced to the Pico scenario described in 3GPP TR 25.951 4. A model indoor environment is specified below and consists of a large office building with an open floor plan layout. Figure1 shows a diagram of the environment. The parameters of the Pico environment are the
39、 following: - building size = 100 x 100 metres ETSI ETSI TR 136 931 V14.0.0 (2017-04)83GPP TR 36.931 version 14.0.0 Release 14- room size = 23 x 20 metres - corridor width = 4 metres Figure 5.3.1.1-1 Pico deployment 5.3.1.2 Macro-Pico deployment The hexagonal cells represent the macro cells and the
