  • Patent number: 10797580
    Abstract: A detection circuit for detecting an inductor current flowing through an inductor is provided. The inductor is coupled to a switch. The detection circuit includes a comparison circuit and a signal generating circuit. The comparison circuit, having a first node, is configured to compare a conduction time of a diode of the switch with a time threshold to provide a first voltage at the first node. The signal generating circuit, coupled to the first node, is configured to output a first detection signal according to the first voltage. The first detection signal indicates whether the inductor current flowing through the inductor reaches a first current threshold. A switching regulator comprises the detection circuit. A control method controls the switching regulator.

  • Patent number: 10778377
    Abstract: Methods, apparatuses and a user equipment for performing a Hybrid Automatic Repeat Request (HARQ) transmission in a downlink from a base station to at least one user equipment are provided. An exemplary method comprises receiving a HARQ feedback to a HARQ transmission performed with respect to a transport block. The method further comprises determining whether the HARQ feedback is an ambiguous HARQ feedback with respect to a negative acknowledgement or a discontinuous transmission. The method additionally comprises setting (S206) the ambiguous HARQ feedback as the negative acknowledgement or the discontinuous transmission based on the number of HARQ transmissions having been performed and the corresponding received HARQ feedbacks within a target number of HARQ transmissions counting from a first HARQ transmission. With the methods and apparatuses, the ambiguity of the HARQ feedback can be overcome and communication efficiency may be improved.
