  • Publication number: 20200374871
    Abstract: Various embodiments provide a relay transmission method, where a first node is a parent node of a second node. In those embodiments, a request message from the first node can be received by the second node, where the request message is configured to request the second node to become a parent node of the first node. Still in those embodiments, indication information can be sent, by the second node, to the first node, where the indication information is used to indicate that a downlink beam sent from the second node to the first node after the second node becomes the parent node is the same as or similar to an uplink beam sent from the second node to the first node when the first node is the parent node. The indication information may be carried in a response message for the request message.

  • Patent number: 10846643
    Abstract: A request is received for determining a task completion rate of each of a first set of tasks associated with a set of task attributes. The first set of tasks are scheduled to be completed within a first timer period. An MAPE score is calculated or obtained for each of the completion rate predictive models, which is determined based on prior predictions performed in a second time period in the past. The duration of the second time period is a multiple of the first time period. One of the predictive models is selected based on the MAPE scores of the predictive models, where the selected model has the lowest MAPE score amongst the predictive models in the set. In another embodiment, a predictive model is selected further based on the volatility scores of the predictive models. A model with a combination of lowest MAPE score and volatility score is selected.
