    Abstract: Technology for an eNodeB operable to perform multiuser non-orthogonal superposition transmissions for multimedia broadcast multicast service (MBMS) is disclosed. The eNodeB can modulate a first physical multicast channel (PMCH) signal for MBMS with a first modulation and coding scheme (MCS). The eNodeB can modulate a second PMCH signal for MBMS with a second MCS. The eNodeB can multiplex the first PMCH signal and the second PMCH signal to form an aggregate PMCH signal. The eNodeB can transmit the aggregate PMCH signal to a plurality of UEs using multiuser non-orthogonal superposition for MBMS, wherein the first PMCH signal in the aggregate PMCH signal is transmitted using physical resource blocks (PRBs) that are partially or fully overlapped in time and frequency with PRBs of the second PMCH signal in the aggregate PMCH signal.

    Abstract: A reflect array-feeding array (RA-FA) antenna is disclosed. The RA-FA antenna comprising: a reflect array base comprising a plurality of reflecting elements with a phase shift distribution to reflect an incident beam to generate a reflected beam having a narrower beamwidth in an elevation plane and a same beamwidth in an azimuth plane, and a feeding array comprising a phased antenna array with a beam-steering ability to direct the incident beam at the reflecting elements. The reflecting elements may be configured in a pattern with rows and columns and reflecting elements along rows have a same phase shift, and reflecting elements along columns have phase shifts to narrow the incident beam to form the reflected beam narrower in the elevation plane.
