  • Publication number: 20190179064
    Abstract: A polarization insensitive optical phased array is provided, for LIDAR or other purposes. A polarization rotator splitter or two-dimensional grating coupler provides two components of co-polarized (e.g. TE-polarized) light. Each component can be routed to a separate optical phased array (OPA) component, and light output of one of the OPA components is rotated in polarization by use of a half wave plate. A polarization controller can receive and control the two components of co-polarized light and then passes the controlled light to the two OPA components. A single OPA component can also be used along with a controller which combines the two components of co-polarized light into a single output, passed to the single OPA component.

  • Publication number: 20190182802
    Abstract: A control information communication method, a base station, and user equipment are provided. A determination is made whether downlink control information (DCI) is used for multicast transmission or for paging. When the DCI is determined to be used for multicast transmission, the DCI is scrambled by using a single cell radio network temporary identifier (SC-RNTI). The DCI includes indication information and scheduling information, the indication information indicating whether a multicast control channel is updated. When the DCI is determined to be used for paging, the DCI is scrambled by using a paging radio network temporary identifier (P-RNTI). The scrambled DCI can be sent to user equipment by using a first downlink control information format.

  • Patent number: 10318297
    Abstract: A self-timed parallelized multi-core processor has an instruction decoder unit for receiving a program code instruction, determining an operating code and latency for the instruction, and assigning a loop index to the instruction. An instruction decomposer creates a primitive by decomposing the instruction, replacing the loop index with a core index, and broadcasting the primitive. Self-timed processing cores each having a unique core index compare the core index to their unique processing core index. The processing cores act on the primitive when their processing core index is within a threshold of the core index.
