This paper experimentally verifies how the parallelogram planar array (PPA) can improve the space division multiplexing (SDM) performance of multiuser massive multiple-input multiple-output (MIMO) in line-of-sight (LOS) channels. PPA can reduce the spatial channel correlation (inter-user correlation) without any increase in processing load. Channel state information (CSI) of up to 94 antenna elements is measured with simplified test equipment in an outdoor propagation environment. Assessment of the measured CSI confirms the effectiveness of PPA in terms of reduced spatial channel correlation and its higher order SDM ability with simplified user scheduling.

“…We have proposed the massive antenna system for wireless entrance (MAS-WE); it provides high system capacity backhaul links to widely distributed small cells via massive multiple-input multiple-output (MIMO) transmission [2,3]. If the entrance base station (EBS) and relay stations (RSs) are installed at fixed (high) locations, the line-of-site (LoS) environment is expected since RS locations can be flexibly selected.…”

This letter proposes continuous beamforming space division multiple access (CB-SDMA) on massive antenna systems for wireless entrance (MAS-WE). Entrance base station hosts an individual baseband signal processing unit for each relay station and continuously applies beamforming weights to transmission/reception signals. It yields virtual point-to-point type backhaul links so radio resource control messages and complicated multiuser scheduling are not required; medium access control is very simple. A computer simulation examines the acceptable CB number and expected throughput performance with given offered load.
