Table 1 Simulation parameters
From: Interference management for moving networks in ultra-dense urban scenarios
| Component | Configuration parameters |
|---|---|
| Buildings and streets | Nine buildings 120 by 120 m with six floors (3.5 m height of each floor), see Figure 1. |
| Road width 21 m (including sidewalks and parking lanes) | |
| Macro BS | Height: 5 m above the top of the middle building (see Figure 1) |
| Maximum transmit power (per 10 MHz): 43 dBm | |
| Carrier: 800 MHz | |
| Bandwidth: 20 MHz | |
| Antenna configuration: 17 dBi gain, three sectors (one antenna per sector), 0°, 120°, and 240° with respect to the north | |
| Micro BS | Height: 10 m above the ground close to middle point of south and east walls |
| Positions: see Figure 1 | |
| Maximum transmit power (per 10 MHz): 30 dBm | |
| Carrier: 2.6 GHz | |
| Bandwidth: 80 MHz | |
| Cell range expansion bias: 5 dB | |
| Antenna configuration: 17 dBi gain, two sectors (one antenna per sector), pointing to the main street with an angle of 20° with respect to the closest wall | |
| Moving network | Full-duplex |
| Speed: 50 km/h | |
| Height: 3.5 m above the ground | |
| Mobility model: public transportation vehicles enter each street through a Poisson process with an inter-arrival time of 2 min | |
| Maximum transmit power indoor (per 10 MHz): 10 dBm | |
| Carrier: 800 MHz for backhaul links, and 2.6 GHz for access links | |
| Bandwidth: 20 MHz for backhaul links and 80 MHz for access links | |
| Antenna configuration both indoor and outdoor: single antenna, | |
| 0 dBi gain omnidirectional antenna | |
| Receiver noise figure: 5 dB | |
| Outdoor UEs (macro UE, micro UE) | Speed: 0 to 3 km/h |
| Height: 1.5 m above the ground | |
| Positions: uniformly randomly dropped, 50 UEs per road | |
| Cell selection: based on received power with 5 dB CRE bias for micro cells | |
| Receiver noise figure: 9 dB | |
| VUEs | Height: 1.5 m above the ground |
| Position: uniformly randomly dropped inside a vehicle | |
| Number of VUEs in each vehicle: 1) uniformly from the interval | |
| [1, 50]; 2) 25 VUEs per vehicle | |
| Cell selection: 1) same as macro UEs (baseline case); 2) always connect to the MN of their own vehicles (other cases) | |
| Receiver noise figure: 9 dB |
