  • Patent number: 11956108
    Abstract: Apparatus and methods for sounding reference signal (SRS) switching are provided. In certain embodiments, a controller internal to the power amplifier module initiates a sequence of instructions, in response to a single command from UE. The instructions cause a reduction in RF signal amplitude at the power amplifier output and then cause the antenna switch to actuate. Thus ensuring a single command transition and preventing over-power on the power amplifier and antenna switch. The teachings herein can be used to facilitate reduction in gap times between transitions on different antennas and avoid the use of a blank symbol before and after each SRS symbol.

  • Patent number: 11947771
    Abstract: A client computing system (CCS) receives a download including (i) an image representative of at least one circuit in a vehicle, the at least one circuit including a first circuit configured for carrying a first signal within the vehicle, and (ii) symbol data associated with at least one symbol, the at least one symbol including a first symbol. After receiving the download, the CCS displays the image and the at least one symbol. The CCS then receives a first input corresponding to selection of the first symbol. The CCS then responsively receives, from the vehicle, data representing value(s) of the first signal. The CCS then determines a first display-location at which to display the data representing the value(s) of the first signal. While the image and the at least one symbol are displayed, the CCS then displays, at the first display-location, the data representing the value(s) of the first signal.
