36、ass - introduction of BS transmission and reception requirements, but no baseband performance requirements - update of conformance test specifications 5 System scenarios This clause describes the system scenarios for LTE operation that are considered when defining LTE Pico BS class. It also includes
37、 typical radio parameters that are used to derive requirements. 5.1 Pico NodeB class Pico Base Stations are characterised by requirements derived from Pico 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
38、 on the MCL values due to different frequency bands is for FFS. 5.2 Radio scenario Pico radio scenarios have these characteristics: relatively large coverage, dense user population, easy and flexible installation, and large capacity data service. Pico BS is typically used in indoor offices, indoor h
39、otspots, 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 deployment This modelling is referenced to the Pico scenario described in 3GPP TR 25.951 4. A model indoor environment is specified below and co
40、nsists 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 following: - building size = 100 x 100 metres - room size = 23 x 20 metres - corridor width = 4 metres ETSI ETSI TR 136 931 V15.0.0 (2018-07)83
