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).

Abstract: Techniques for snapshot classification involve generating a plurality of snapshots of a storage system at multiple times; clustering the plurality of snapshots into a first group of snapshots and a second group of snapshots based on data features of the plurality of snapshots; and determining a clean snapshot among the plurality of snapshots based on a comparison between the generation time of the first group of snapshots and the generation time of the second group of snapshots. Accordingly, a clean snapshot and a damaged snapshot can be automatically and quickly distinguished, thereby improving the efficiency of finding a clean snapshot and helping a user recover data quickly.

Abstract: A computer-implemented method for aligning a sensor to reference coordinate system includes initiating a plurality of threads, each thread executes simultaneously and independent of each other. A first thread parses data received from the sensor and stores the parsed data in a data buffer. A second thread computes an alignment transformation using the parsed data to determine alignment between the sensor and the reference coordinate system. The computing includes checking that the data buffer contains at least predetermined amount of data. If at least the predetermined amount of data exists, an intermediate result is computed using the parsed data in the data buffer; otherwise, the second thread waits for the first thread to add more data to the data buffer. The second thread outputs the intermediate result into the data buffer. A third thread outputs the alignment transformation, in response to completion of alignment computations.

Abstract: Techniques are described for enabling a database service to provide a zonal consistency model for read and write operations involving database tables replicated across a plurality of availability zones of a cloud provider network according to some embodiments. A database service routes zonally consistent operations to request routers and storage nodes that are located in a same availability zone as the client device from which the request originates. For example, in contrast to standard write operations and strongly consistent read operations, which are processed by a leader storage node that may be located in a different availability zone than the originating request, zonally consistent operations can be processed by any storage node and, in particular, by a storage node in a same availability zone as the originating client device.

Abstract: Replicas may be added to a multi-leader replica group for a data set. A new replica may be added to a group of replicas by copying a version of the data set according to a point in time to the new replica. As updates may occur at different ones of the replicas when the new replica is added, updates that occurred at a source replica for the snapshot and other replicas may be replicated by the different replicas according to the point in time at which the snapshot is created without blocking updates at any of the replicas in the replica group.
