摘要
Abstract
This paper presents an empirical study of the uplink and downlink azimuth angle of arrival (AoA) in an urban micro (UMi) scenario at 28 GHz. At present
most UMi measurements are conducted in the downlink and then the uplink situation is inferred assuming channel reciprocity. Although the channel correlation coefficient of the uplink and downlink can be as high as 0.8
this does not mean that they are the same. Only a real uplink measurement can accurately describe its channel conditions
and this is what this study does. A receiver equipped with a rotatable horn antenna is mounted at the base station and the user terminal
respectively
in simulating the uplink and downlink. To improve the angular resolution
we extract the multipath components (MPCs) using the space-alternating generalized expectation-maximization algorithm. Also
a spatial lobe approach is used to cluster the MPCs in the power angular spectrum. By matching MPCs with objects in the environment
we find that direct propagation and first-order reflections are dominant in line-of-sight and non-line-of-sight cases. By comparing our measurement with those in standard channel models
we verify that the AoA of clusters follows a Gaussian distribution in the uplink and downlink. In addition
a two-dimensional Gaussian distribution for ray AoA and power is established to reflect their correlation.
