  • Patent number: 10979891
    Abstract: In a 5G network, new radios (NR) can be deployed as a standalone radio access technology or as a non-standalone radio access technology assisted by another radio access technology. Long-term evolution (LTE), which is widely deployed can provide seamless coverage and uninterrupted connectivity, however NRs can provide significantly increased data rates or new services. However, the deployment of NR can be limited to hotspots under the footprint of LTE. Therefore, dual connectivity between LTE and NR can be utilized for non-standalone NR because control plane functions can be sent over LTE while the data plane can be managed on NR, allowing for simplified NR deployments where device support for both LTE and NR is available.

  • Patent number: 10959236
    Abstract: A system and method for characterizing an interference demodulation reference signal (DMRS) in a piece of user equipment (UE), e.g., a mobile device. The UE determines whether the serving signal is transmitted in a DMRS-based transmission mode; if it is, the UE cancels the serving DMRS from the received signal; otherwise the UE cancels the serving data signal from the received signal. The remaining signal is then analyzed for the amount of power it has in each of four interference DMRS candidates, and hypothesis testing is performed to determine whether interference DMRS is present in the signal, and, if so, to determine the rank of the interference DMRS, and the port and scrambling identity of each of the interference DMRS layers.
