    Dear Community,

    Can I adapt the RRH network parameters to execute Macro-Pico Scenario in LTE-A HetNet network?
    – 7_Macro_eNBS –each with_3Sectors
    – 3_Pico_eNBS per Macro_eNBs, that is each macro with one pico_eNB deploy
    – CRE and ABS implementation

    I tried implementing it with femtos but it did not go too well.

    Dear Lomax,

    The RRH does not fit in what you want to implement. For an LTE-A HetNet consisitng of macro-pico base stations, you can use the launcher file of femtocells. The femtocell implementation is quite general and allows for easy modifications such as: you can change the number, distribution and position of small cell (pico or femto) base station, transmit power, macroscopic pathloss model used, you can set the pico-cells to open subscriber mode (OSG) and so forth.

    Dear Fjolla,

    Thanks so much.

    Is there a way i can define a fix distance between the Macrocell and the Picocell, Using the femtocell implementation?

    Dear Lomax,

    Yes, it is possible to predefine pico-base station positions. Currently we only support ‘homogenous density’ and ‘constant femtos per cell’ for small cell distribution, however easily you can add more cases, by modifying +network_generation/add_femtocells.m (adding a new case for LTE_config.femtocells_config.spatial_distribution; lines 10 – 27) and defining this new case in +spaial_distibutions. Or you can just overwrite the parameter femtocell_pos in the same file, by adding the desired coordinates in x and y.

    Best regards,

    Dear Fjolla,

    Thanks!!

    Can Almost Blank Subframe(ABS) and Cell range expansion also be implemented? If so, how can you access its performances and graph?

    Hi Lomax,

    you already asked this question (see https://www.nt.tuwien.ac.at/research/mobile-communications/forums/topic/implementation-of-abs-and-cre/).

    If the answer there was not satisfactory, please stick with the original topic and post your further questions there.

    Best,
    Martin
