    Dear Moderators,

    In 2×2 or 4×4 3D model, when setting the LOS_map to 1, to make all UE in line of sight (LOS).

    1-Does the diversity impacted as a result of LOS transmission between BS and UE ? as a consequence of MIMO channel correlation ?

    2- And is the channel in this case Rayleigh ?
    3- Does this scenario support MIMO CLSM ? despite the existence of LOS. Is it the same as having NLOS ?

    Your input is highly appreciated,

    Dear Naser,

    In the case of 3D model, the chanel statistics are different, thus the channel is not Rayleigh. The difference between LOS and NLOS is that for LOS the direct path is dominant, but there are also multipaths comming from other directions that are weaker. The channel follows different statistics for LOS and NLOS as specified in 3GPP TR 36.873.

    Yes, it supports CLSM transmission mode.

    Best regards,
    Fjolla
