  • Patent number: 10574387
    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.

  • Patent number: 10038484
    Abstract: Systems and methods use multiple spatial layers for physical multicast channel transmission. Certain embodiments introduce additional multimedia broadcast multicast service reference signals that support more than one antenna ports for multicast broadcast single frequency network transmissions. To reduce channel estimation complexity due to the multicast broadcast single frequency network reference signal design, resource elements of the multicast broadcast single frequency network reference signals may have a nested structure. To assist modulation and coding scheme selection, a user according to certain embodiments also independently reports block error rate measurements for each spatial layer of the multicast channel.

  • Publication number: 20180124708
    Abstract: Examples include techniques for determining power offsets of a physical downlink shared channel (PDSCH). In some examples higher and physical layer signaling may be provided to user equipment (UE) by a base station such as an evolved Node B to enable the UE to determine power offset values for a multiplexed PDSCH having a serving PDSCH and a co-scheduled PDSCH transmitted via use of same time and frequency resources. The determined power offset values for use by the UE to demodulate the serving PDSCH and mitigate possible interference caused by the co-scheduled PDSCH. Both the UE and the eNB may operate in compliance with one or more 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) standards.
