  • Patent number: 11323221
    Abstract: Various embodiments provide a method for receiving reference signal and a method for sending a reference signal. In those embodiments, a terminal device can determine a location of a resource element to which a reference signal is mapped. The terminal device can determine a reference signal sequence corresponding to the resource element. The index of each element in the reference signal sequence is determined based on a resource block index of a resource block corresponding to the resource element, a quantity of resource elements that carry the reference signal in the resource block, a resource block offset, or an inter-symbol offset. The terminal device can receive the reference signal by using the resource element, and performing channel estimation or channel sounding based on the received reference signal and the reference signal sequence. Therefore, the terminal device can complete channel estimation without learning of a system bandwidth.

  • Publication number: 20220093093
    Abstract: A system can operate a speech-controlled device in a mode where the speech-controlled device determines that an utterance is directed at the speech-controlled device using image data showing the user speaking the utterance. If the user is directing the user's gaze at the speech-controlled device while speaking, the system may determine the utterance is system directed and thus may perform further speech processing based on the utterance. If the user's gaze is directed elsewhere, the system may determine the utterance is not system directed (for example directed at another user) and thus the system may not perform further speech processing based on the utterance and may take other actions, for example discarding audio data of the utterance.

  • Patent number: 11275366
    Abstract: In one embodiment, a management entity monitors for a change in a convergence rate of spatio-temporal compressive sensing measurements from a plurality of sensors in a sensor network operating according to a measurement matrix up to a halting criterion, and if the change is below a given threshold, determines whether the change is due to impulse noise or due to continued sensed measurements. If continued sensed measurements, the management entity initiates a single-dimensional compressive sensing in a spatial domain at regular time intervals, and identifies and tracks gradient clusters. In response to a change in joint spatio-temporal sparsity of tracked nodes of the gradient clusters, the management entity can then determine an updated measurement matrix based on the joint spatio-temporal sparsity of tracked nodes while satisfying one or more operating parameters, and directs at least certain sensors of the plurality of sensors to operate according to the updated measurement matrix.
