Efficient Sum-of-Sinusoids based Spatial Consistency for the 3GPP New-Radio Channel Model
, 2018 Spatial consistency was proposed in the 3GPP TR 38.901 channel model to ensure that closely spaced mobile terminals have similar channels. Future extensions of this model might incorporate mobility at both ends of the link.
