    Abstract: Technology for an UE operable to report channel state information (CSI) for multi-user superposition transmissions (MUST) is disclosed. The UE can process a plurality of power offset parameters that are received from an eNodeB, for the MUST. The UE can perform a downlink channel measurement at a user equipment (UE). The UE can scale the downlink channel measurement using at least one of the plurality of power offset parameters to form one or more scaled downlink channel measurements. The UE can calculate CQI values for the one or more scaled downlink channel measurements. The UE can process, for transmission to the eNodeB, the CQI values for the one or more scaled downlink channel measurements to enable the UE to receive data on a physical downlink shared channel (PDSCH) using multi-user superposition transmission.

  • Patent number: 10389494
    Abstract: Systems, apparatus, user equipment (UE), evolved node B (eNB), computer readable media, and methods are described for uplink grants and hybrid automatic repeat requests (HARQ) in communications systems. Some embodiments operate to determine that an unlicensed first channel is idle based on a sensing of the first channel for a first period of time. Such an embodiment may then generate a reservation signal on the first channel and an uplink grant for a first user equipment (UE). After the uplink grant is communicated, the embodiment senses the first channel to detect a physical uplink shared channel (PUSCH) transmission associated with the uplink grant. A HARQ acknowledgment or negative acknowledgement may be sent in various embodiments following the sensing.
