  • Patent number: 11943065
    Abstract: In one configuration, multiple TRPs, or base stations such a next generation node B (gNB) base stations send different transport blocks (TBs) to a user equipment (UE) at the same time or at different times. In another configuration, multiple base stations may send the same data at the same time to a UE. When the same data is being sent by multiple base stations to a UE, the UE must be notified by some mechanism. Disclosed herein are multiple mechanism for notifying the UE that multiple base stations will be transmitting toe same data at the same time. When there is a backhaul between a TRP and another, each TRP can choose to send the same data stream to increase the reliability of the transmission when, for example, the UE receives at a low signal-to-noise ratio (SNR).

  • Patent number: 7941298
    Abstract: An apparatus, computer program product and method of analyzing complex signals. Independent versions are generated for the complex signal, e.g., by adding multiple instances of white noise. Intrinsic mode functions (IMFs) are extracted from each of the independent versions, e.g., using Empirical Mode Decomposition (EMD). Corresponding IMFs from each independent version are combined into Ensemble IMFs (EIMFs), e.g., taking the mean of the corresponding IMFs.
