  • Publication number: 20200059395
    Abstract: Some of the present implementations provide a method for a user equipment (UE) for reporting a master node (MN) failure. The method, in some of the present implementations detects, at the UE, a failure in a radio link to the MN. The method determines whether the UE is configured with a split signaling radio bearer (SRB). The method then transmits an MN failure report to the MN using a secondary node (SN) path of the split SRB after determining that the UE is configured with the split SRB. The method of some of the present implementations maintains current measurement configurations received from the MN and the SN, and continues to perform measurements based on the configurations received from the MN and the SN after determining that the radio link to the MN has failed.

  • Publication number: 20200031818
    Abstract: A method of providing spatial diversity for critical data delivery in a beamformed mmWave small cell is proposed. The proposed spatial diversity scheme offers duplicate or incremental data/signal transmission and reception by using multiple different beams for the same source and destination. The proposed spatial diversity scheme can be combined with other diversity schemes in time, frequency, and code, etc. for the same purpose. In addition, the proposed spatial diversity scheme combines the physical-layer resources associated with the beams with other resources of the same or different protocol layers. By spatial signaling repetition to avoid Radio Link Failure (RLF) and Handover Failure (HOF), mobility robustness can be enhanced. Mission-critical and/or time-critical data delivery can also be achieved without relying on retransmission.

    Abstract: A sensing system includes a sensor assembly and a back end server system. The sensor assembly includes a collection of sensors in communication with a control circuit. The sensors are each configured to sense one or more physical phenomena in an environment of the sensor assembly. The control circuit of the sensor assembly is configured to identify one or more selected sensors of the collection of sensors whose data corresponds to an event occurring in the environment of the sensor assembly and transmit data to the back end server system. The back end server system is configured to generate a first order virtual sensor by training a machine learning model to detect the event based on the data from at least one of the selected sensors and detect the event using the trained first order virtual sensor and data from the selected sensors.

  • Publication number: 20200029239
    Abstract: Some of the present implementations provide a method for reporting measurement results by a user equipment (UE). The method receives, at the UE, a radio resource control (RRC) release message to transition to an RRC Inactive state. The method of some of the present implementations performs measurements while in the RRC Inactive state. The method then receives an RRC resume message from a base station, the RRC resume message comprising a request for the measurement results. After receiving the RRC resume message, the method transmits the measurement results to the base station in an RRC resume complete message.
