Abstract
A system method and apparatus for hybrid beamforming based network multiple input and multiple output (MIMO) is disclosed. At least one wireless transmit/receive unit (WTRU) may measure channel state information (CSI) and send the information to a next generation NodeB (gNB) of a small cell. The gNB may receive CSI from the at least one WTRU and may aggregate the CSI when received from more than one WTRU. The gNB may compute a precoding matrix for each of the WTRUs or the gNB may receive a computed precoding matrix from a network controller. The gNB may also compute postcoding matrices for each of the WTRUs. The at least one WTRU may receive data from the gNB or may receive data simultaneously from more than one gNB that has been individually encoded for each of the at least one WTRU.
