 which enabled further work in 3GPP for the advanced antenna technology LTE Macro Cell Evolution evolution, with the work on-going in Release 13 to go beyond eight antenna ports together with the necessary enhancements for the UE feedback and other details relevant for the use of more than eight antenna ports. The use of 3D-beamforming/full-dimension MIMO-related elements is expected to be added during the work of Releases 13 and 14 of LTE-Advanced evolution. Further work on receiver will, on the other hand, extend the CRC interference can- cellation capabilities in homogenous networks as well as look at the application of NOMA-type transmission/reception with two users sharing the same resources with power differences.
