    Hi,

    Is it possible to control the femto/macro transmit power due to the SINR information in the simulator?

    Which files should be changed ?

    Hi,

    yes, that’s possible. The SINR is calculated in the link_quality_model in +network_elements.UE
    The transmit powers are properties of +network_elements.eNodeB_sector (for both macros and femtos).

    In the simulator document it is stated that for LTE_config.power_allocation only “homegeneous” is supported.

    Does it mean that I can’t assign different tx power values for different base stations.

    Is it possible for each small cell to assign different tx power levels to mitigate interference in heterogeneous networks.

    Can I make some modifications in the code to assign different tx power levels for small cells.

    Hi,

    – homogeneous means that the total power is homogeneously distributed over all RBs.
    – You can assign different powers to different eNBs/femtocells. You have to write your own routine for this, which you can insert, e.g., in LTE_init_network_generation.

    I would like to thank you for the replies.

    In the simulator the power values are assigned and then the SINR values are calculated before the scheduling process.

    I think after the SINR values are calculated it is still possible to define new power levels to the eNB/femto cells.

    Is that right?

    Besides,
    is it possible to change the tx power levels during the scheduling process is performed, e.g. after a determined time?

    Best Regards

    Hi,

    – yes, you can still alter the power levels after calculating the wideband-SINR, which mainly serves to determine the sector assignment.
    – yes, it is possible to change the power levels during the scheduling process. You will have to implement this by yourself though.

    Best regards,
    Martin.
