  • Patent number: 10374768
    Abstract: A method of identifying reference signal resources to be used in a transmission by a wireless device is disclosed. The method comprises a wireless device receiving signaling configuring the wireless device with a plurality of reference signal resource groups, each group comprising a plurality of reference signal resources. The wireless device subsequently receives an indication, in a control channel, of a selection of reference signal resources to be used. Each of the plurality of reference signal resources to be used is selected from a different one of the plurality of reference signal resource groups such that reference signal resources belonging to the same reference signal resource group are not selected for simultaneous use. A reference signal is then transmitted to a network node in the network using the indicated selection of reference signal resources.

  • Publication number: 20190238262
    Abstract: Systems and methods are provided for deriving channel feedback for a physical channel based on an indication of the number of transmission repetitions. In some embodiments, a method for use in a wireless device for determining channel feedback for a physical channel includes receiving control signaling including an indication of a number of transmission repetitions of the physical channel. The method also includes deriving the channel feedback for the physical channel based on the indication of the number of transmission repetitions, where a code rate corresponding to the channel feedback corresponds to an effective channel code rate of the physical channel occupying a group of physical resources including the number of transmission repetitions. In this way, the wireless device may report channel conditions that are better than the channel conditions corresponding to a single transmission, according to some embodiments.

  • Publication number: 20190209372
    Abstract: Provided herein is a probe for treating an eye of a patient. In one or more embodiments, the probe includes a body, and a tubular element having a main lumen extending from the body, the tubular element comprising a distal end. The probe further includes a visualization optical fiber within the main lumen, the visualization optical fiber adapted to emit an illumination provided by at least one of a plurality of light sources connected to the visualization optical fiber. In some embodiments, the probe further includes an optical switching system (e.g., a time-division multiplexor) operable with the plurality of light sources, wherein the optical switching system is adapted to independently control each of the plurality of light sources. By providing time-division multiplexing between different surgical light sources, quasi-simultaneous illumination delivery through the same optical path may be achieved.

  • Patent number: 10299505
    Abstract: A method of steam cleaning a roaster bowl, such as one used in a roasting/glazing apparatus, in which an electronic technique is employed to determine, during cleaning, whether water is boiling within the roaster bowl. The method entails adding water into a roaster bowl having sugar adhered thereto and placing a cover on top of the roaster bowl. A steam vent is formed between the cover and the roaster bowl. The method further comprises heating the roaster bowl and then electronically determining whether the water within the roaster bowl has reached a boiling point (i.e., is boiling). After electronically determining that the water is boiling, the water remains boiling for an amount of time sufficient to cause the internal surface of the roaster bowl and the cover to be properly steam cleaned. The water in the roaster bowl (with sugar dissolved therein) is then poured out.

  • Publication number: 20190158161
    Abstract: Example embodiments are presented for codebook subset restriction and precoder selection in wireless communications systems. For instance, an example method for codebook subset restriction at a user equipment (UE) is presented. In the example method, the UE can receive, from a network node such as a gNB, codebook subset restriction (CBSR) signaling for a first component common to precoders in a first group of codebooks. In an aspect of the present disclosure, a restriction of the first component maps to a restriction of a second component and the second component is common to precoders in a second group of codebooks. In addition, the example method includes restricting precoders selectable from a codebook in the second group of codebooks based on the second component. Network-side methods are presented, as well as example UEs and network nodes.
