Abstract: Taking the advantage of elevation angular domain, three dimensional multiple input and multiple output (3D MIMO) with massive antenna elements, is regarded as a promising technique for the fifth generation (5G) mobile communication system. Therefore, the knowledge of 3D spatial channel characteristics has become a basic and vital requirement for the 5G channel model. In this paper, we conducted the 3D MIMO channel measurement at 3.5 GHz with 100 MHz bandwidth in indoor hotspot scenario which is one of the important scenarios for 5G deployment. Based on the channel measurement data, spatial characteristics of elevation angle domain are analyzed and modeled, including power angular spectrum, angular spread, and cross-correlation property, etc. The extracted channel parameters of elevation domain can be used in the 5G technology evaluation and simulation for indoor hotspot scenario.
