  • Patent number: 10305618
    Abstract: Techniques for transmitting and detecting for overhead channels and signals in a wireless network are described. In an aspect, a base station may blank (i.e., not transmit) at least one overhead transmission on certain resources in order to detect for the at least one overhead transmission of another base station. In one design, the base station may (i) send the overhead transmission(s) on a first subset of designated resources and (ii) blank the overhead transmission(s) on a second subset of the designated resources. The designated resources may be resources on which the overhead transmission(s) are sent by macro base stations. The base station may detect for the overhead transmission(s) from at least one other base station on the second subset of the designated resources. In another aspect, the base station may transmit the overhead transmission(s) on additional resources different from the designated resources.

  • Patent number: 10306265
    Abstract: In general, this disclosure describes techniques for simplifying SDC coding of large intra-prediction blocks, such as 64×64 blocks, in a 3D video coding process, such as 3D-HEVC. In some examples, the techniques may include processing 64×64 intra-prediction blocks as four 32×32 intra-prediction blocks in intra SDC. Processing large intra-prediction blocks as multiple, smaller intra-prediction blocks in intra SDC may reduce maximum buffer size requirements in the intra SDC process.

    Abstract: Techniques for mute pattern injection for a pulse-density modulation microphone are described. In one or more implementations, a pulse-density modulation (PDM) microphone includes a transducer that receives a pressure wave and produces an analog signal that represents the pressure wave, an analog-to-digital converter (ADC) that receives the analog signal from the transducer and converts the analog signal into a digital PDM signal. The PDM microphone also includes a pattern generator that generates a digital mute signal, a controller that outputs control signals, and a multiplexer that receives the control signals, the digital mute signal, and the digital PDM signal. The multiplexer transmits the digital mute signal or the digital PDM signal, responsive to the control signals.

  • Patent number: 10306660
    Abstract: Wireless devices in a wireless network may use multiple communication modes to perform device-to-device (D2D) communication in a mesh wide area network (WAN). For instance, one communication mode may be contention-based, while the other communication mode may be scheduled (e.g., by a relay). To facilitate co-existence between these communication modes, a wireless device may identify a set of resources set aside for D2D communications and may select and reserve a transmission time interval (e.g., a slot) of the D2D resources. Other wireless devices may determine the transmission time interval is reserved and refrain from transmitting during that transmission time interval. In another example, a base station may assign a D2D communication mode to certain sets of D2D resources.

  • Patent number: 10304468
    Abstract: A method of encoding audio channels includes receiving two or more channels at an encoder and identifying a target channel and a reference channel. The target channel and the reference channel are identified from the two or more channels based on a mismatch value. The method also includes generating a modified target channel by temporally adjusting the target channel based on the mismatch value. The mismatch value is indicative of an amount of temporal mismatch between the target channel and the reference channel. The method also includes determining a temporal correlation value indicative of a temporal correlation between a first signal associated with the reference channel and a second signal associated with the modified target channel. The method also includes comparing the temporal correlation value to a threshold. The method further includes generating missing target samples based on the comparison, a coder type, or both.
