CPC Class H04W

A method and a device for determining a device placement to optimize techniques, such as power management techniques, are described. The method, executed in a processor of a mobile device, comprises gathering data from at least one sensor associated with the mobile device. Based on the data gathered from the sensor, a device placement indicative of at least one of an orientation and a position the mobile device may be determined. Further, details pertaining to the device placement may be integrated with secondary classification data comprising at least one of historical data, device orientation data, and device motion data. Based on the integrated details, it may be inferred whether a user is engaged with the mobile device. When a user is not engaged with the mobile device, a brightness of the display is lowered in at least one stage to optimize power consumption and user experience.

An example apparatus includes a memory configured to store the audio data; and one or more processors in communication with the memory, the one or more processors configured to: obtain, for each of a plurality of subbands of audio data, a respective energy scalar and a respective residual identifier; determine overall distortion levels for a plurality of candidate subband pulse allocations for performing pyramid vector dequantization (PVdQ) of the residual identifiers; select, from the plurality of subband pulse allocations and based on the overall distortion levels, a candidate subband pulse allocation; and perform, using the candidate subband pulse allocation, PVdQ on the residual identifiers to reconstruct a residual vector for each subband.

The invention relates to a background noise estimator and a method therein, for supporting sound activity detection in an audio signal segment. The method comprises reducing a current background noise estimate when the audio signal segment is determined to comprise music and the current background noise estimate exceeds a minimum value. This is to be performed when an energy level of an audio signal segment is more than a threshold higher than a long term minimum energy level, lt_min, which is determined over a plurality of preceding audio signal segments, or, when the energy level of the audio signal segment is less than a threshold higher than lt_min, but no pause is detected in the audio signal segment.

A shielded electrical cable includes conductor sets extending along a length of the cable and spaced apart from each other along a width of the cable. First and second shielding films are disposed on opposite sides of the cable and include cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the films in combination substantially surround each conductor set. An adhesive layer bonds the shielding films together in the pinched portions of the cable. A transverse bending of the cable at a cable location of no more than 180 degrees over an inner radius of at most 2 mm causes a cable impedance of the selected insulated conductor proximate the cable location to vary by no more than 2 percent from an initial cable impedance measured at the cable location in an unbent configuration.

Certain aspects of the present disclosure provide a directional coupler. In certain aspects, the directional coupler generally includes a first inductor and a second inductor wirelessly coupled to the first inductor. In certain aspects, the directional coupler generally includes an input port at a first terminal of the first inductor and a transmitted port at a second terminal of the first inductor. In certain aspects, the directional coupler generally includes a coupled port at a first terminal of the second inductor and an isolated port at a second terminal of the second inductor. In certain aspects, the directional coupler generally includes a first complex impedance component directly coupled to the isolated port and a second complex impedance component directly coupled to the coupled port.

The present invention describes a channel measurement method, including: sending, by a base station, first control information to user equipment UE, where the first control information is used to indicate a measurement reference signal of the UE on a carrier, and the first control information includes at least one first measurement configuration set, and is used to instruct the UE to measure the measurement reference signal based on the at least one first measurement configuration set; sending, by the base station, the measurement reference signal to the UE.
