Abstract: In this article we compare the performance of two typical hyrbid beamformingstructures for multiuser massive MIMO systems, i.e., the full- andpartial-connection structures. Under the assumption of small angular spread formmWave channels, given the analog precoder formed towards users and thezero-forcing digital precoder, we develop an explicit upper bound for theanalog-and-digital-precoded channel gain of users, based on which therelationship between the two structures is investigated. The analysis resultsshow that the full-connection structure is not always better than thepartial-connection structure, and the regimes suitable for each structure arerevealed. Simulations are conducted to validate the analysis results.
