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
