    摘要: In general, this disclosure relates to techniques for quieting data transmission functionality during spectrum sensing operations. In one aspect, a method for spectrum sensing comprises detecting, during at least one time interval, whether any channel of a spectrum is available for use, and refraining, during the at least one time interval, from transmitting any data from a communication device.

    摘要: This disclosure relates to techniques for synchronizing playback of media data between a source device and one or more sink devices in a Wireless Display (WD) system. WD systems enable mobile devices to share a local display of the source device with remote sink devices. The techniques of this disclosure include a management procedure at the source device to select a universal queue size for the source device and the participating sink devices. The source device selects the universal queue size based at least on supported queue sizes of the source device and the sink devices. The media packets are then held in queues having the universal queue size at the source device and the sink devices. The uniform queue size combined with compensation for transmission delay enables each of the devices to begin processing the media packets at the same time.

    摘要: In general, this disclosure relates to techniques for transmitting data in a spectrum, and seamlessly switching from one transmission channel to an available channel in the spectrum. One example method comprises identifying, by a device, at least a first channel of a spectrum, transmitting at least one command to a second, different device, wherein the at least one command contains information that allows the second device to determine at least the first identified channel, and transmitting data in at least the first identified channel.

    摘要: Aspects of this disclosure relate to a method that includes, in an example, sending, by a source device, display data to a sink device for rendering on the sink device. The method also includes receiving, by the source device, an indication of user input at a first display location of a touch-sensitive screen associated with the source device, wherein the user input specifies a modification of at least a portion of the display data rendered at the sink device, wherein the portion of the display data is rendered at a second display location of the sink device. The method also includes, in response to receiving the indication, sending, by the source device, second configuration data to modify the portion of the display data rendered at the second display location based at least in part on a mapping of the first display location to the second display location.
