  • Patent number: 11392740
    Abstract: Roughly described, the invention involves a system including a plurality of functional units that execute different segments of a dataflow, and share intermediate results via a peer-to-peer messaging protocol. The functional units are reconfigurable, with different units being reconfigurable at different levels of granularity. The peer-to-peer messaging protocol includes control tokens or other mechanisms by which the consumer of the intermediate results learns that data has been transferred, and in response thereto triggers its next dataflow segment. A host or configuration controller configures the data units with their respective dataflow segments, but once execution of the configured dataflow begins, no host need be involved in orchestrating data synchronization, the transfer of intermediate results, or the triggering of processing after the data are received. Control overhead is therefore minimized.

    Abstract: Methods, systems, and devices for wireless communications are described. Generally, a transmitting device may send transmissions using a first numerology for a first type of user equipment (UE). The transmitting device may partition a stream of modulated data symbol tones into one or more contiguous subsets of modulated data symbol tones that result in a roughly frequency-flat channel for a second type of UE. The transmitting device may then perform precoding on individual subsets of the one or more contiguous subsets of modulated data symbol tones, and may insert a frequency-domain cyclic prefix, cyclic postfix, or guard interval after each precoded subset. Thus, the first type of UE may communicate using the first numerology and the second type of UE may communicate using the first numerology but with the frequency-domain cyclic prefixes to address doppler spread experienced by the second type of UE.

  • Patent number: 11271615
    Abstract: Example communications methods and apparatus are described. One example method includes generating a first signal by a base station. The base station performs cyclic delay diversity (CDD) weighted processing on the first signal to obtain a second signal, and performs densified beam weighted processing on the second signal to obtain a third signal. The third signal is sent by the base station via an antenna. According to the foregoing method, the CDD weighted processing is performed on the first signal generated by the base station, so that time diversity can be obtained when the first signal is transmitted. In addition, the densified beam weighted processing is performed on the second signal obtained after the CDD weighted processing, so that a quantity of beams scanned by the base station can be increased.
