Abstract

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.
