Set valid parameters for a specified 3GPP system level scenario (RMa, UMi, or UMa)

If a parameter is given, then it is returned. If it is set to None, then a parameter valid according to the chosen scenario is returned (see [TR38901]).

Parameters:

  • scenario (str) – System level model scenario. One of "uma", "umi", "rma", "uma-calibration", or "umi-calibration".

  • min_bs_ut_dist (float | None) – Minimum BS-UT distance [m]

  • isd (float | None) – Inter-site distance [m]

  • bs_height (float | None) – BS elevation [m]

  • min_ut_height (float | None) – Minimum UT elevation [m]

  • max_ut_height (float | None) – Maximum UT elevation [m]

  • indoor_probability (float | None) – Probability of a UT to be indoor

  • min_ut_velocity (float | None) – Minimum UT velocity [m/s]

  • max_ut_velocity (float | None) – Maximum UT velocity [m/s]

  • precision (str | None) – Precision used for internal calculations and outputs. If set to None, precision is used.

  • device (str | None) – Device for computation. If None, device is used.

Outputs:

  • min_bs_ut_dist – torch.float. Minimum BS-UT distance [m].

  • isd – torch.float. Inter-site distance [m].

  • bs_height – torch.float. BS elevation [m].

  • min_ut_height – torch.float. Minimum UT elevation [m].

  • max_ut_height – torch.float. Maximum UT elevation [m].

  • indoor_probability – torch.float. Probability of a UT to be indoor.

  • min_ut_velocity – torch.float. Minimum UT velocity [m/s].

  • max_ut_velocity – torch.float. Maximum UT velocity [m/s].
