UNABLE TO SIMULATE A COLLOCATED LTE NETWORK WITH TWO FREQUENCY BANDS : L800( band20) and L2600(band7)

[Hassan Abdullahi]

Dear Team,

I am working on a thesis titled: INTER-FREQUENCY LOAD BALANCING IN A MULTI-CARRIER LTE NETWORK USING DEEP REINFORCEMENT LEARNING, and to realize this project, i need to be able to simulate a multicarrier LTE network. 

for the past 4 weeks, I have been trying to simulate an LTE network with 2 carriers: band20 (lte800) and band7(lte2600) ) using ns-3 but it has not been working as expected.

First Challenge:  I intended to use EVENT_A5 but i could not find event 5 on ns-3.48.

Second Challenge: Even the EVENT_3 algorithm does not seem to be working as UEs are not handing over; they got stuck to their initial enodeBs. 

My goal is to generate a dataset that contains: PRB_Utilization_L800, PRB_Utilization_L2600,  RSRP_L800, RSRP_L2600, A5threshold1, A5threshold2 and Throughput_total and my simulated scenarios is as highlighted below:

Number of UEs = 50

Collocated L2600(band7) and  L800(band20)

Handover algorithm: event_A5
