S1022, according to cumulative distribution function and circulation way, determine that CSI-RSRP value is in CSI- under different circulation ways
The probability that the section RSRP occurs.
It should be noted that in actual application, channel is particularly important to the influence of 5G MU-MIMO scene;Without
Same circulation way, will affect channel to the influence of 5G MU-MIMO scene;And corresponding propagation when channel is established in UE and base station
Mode is divided into NLOS and LOS, it is therefore desirable to which calculating circulation way is that NLOS (abbreviation NLOS diameter) corresponding CSI-RSRP value exists
The probability and circulation way that the section CSI-RSRP occurs are LOS (abbreviation LOS diameter) corresponding CSI-RSRP value in CSI-RSRP
The probability that section occurs, specific calculation are as follows:
