    Abstract: Methods, systems, and devices for wireless communication are described. A base station may perform a clear channel assessment (CCA) procedure on a channel that includes multiple sub-bands of a radio frequency spectrum band. The base station may determine that the channel is available based on the CCA and transmit a special header in the channel. In some examples, the special header may include multiple transmission time intervals (TTIs), where each TTI may include a header packet in each sub-band of the radio frequency spectrum band. In some cases, the header packet may include a clear to send (CTS)-to-self frame structure. The base station may transmit a first TTI across each of the sub-bands at a first power level, and transmit additional TTIs across the sub-bands at a different power level. Additional header packets may be transmitted at the boundaries of subsequent subframes.

    Abstract: Methods, systems, and devices are described for techniques for downlink (DL) scheduling and uplink (UL) scheduling in a shared radio frequency (RF)spectrum band. In some aspects, a wireless communication device may receive an UL data transmission grant associated with a channel of shared RF spectrum band. The wireless communication device may perform a channel readiness procedure associated with the channel. The wireless communication device may also transmit channel readiness information based at least in part on the channel readiness procedure to a base station. The channel readiness information may be transmitted via an uplink channel of a licensed RF spectrum band different from the shared RF band. In other aspects, a base station may schedule a data transmission on one or more channels of a shared RF spectrum band. The base station may transmit a data transmission grant for the scheduled data transmission to a wireless communication device.

    Abstract: A method for interactive image caricaturing by an electronic device is described. The method includes detecting at least one feature location of an image. The method further includes generating, based on the at least one feature location, an image mesh that comprises a grid of at least one horizontal line and at least one vertical line. The method additionally includes obtaining a gesture input. The method also includes determining at least one caricature action based on the at least one gesture input. The method further includes generating a caricature image based on the image mesh, the at least one caricature action and the image.

    Abstract: A device (300) for displaying panoramic images includes an image sensor (315), a panoramic display module (345) and a display (325). The display (110, 200) displays an annular panorama view (120, 210). The annular view (120, 210) may be an incomplete annulus for illustrating a missing view angle (126) from an incomplete panoramic image. The display (200) further includes a window (220) and a high resolution display portion (240). The window (220) bounds a portion (230) of the annular view (210). The high resolution display portion (240) displays a high resolution image corresponding to the portion (230) of the annular view (210). The window (220) is movable around the annular view (210). A size of the window (220) or the high resolution display portion (240) is adjustable. A method for generating a panoramic image is also provided.

    Abstract: Methods, systems, and devices for wireless communication are described. A first device in a synchronous network performs a first clear channel assessment (CCA) procedure on a channel; identifies the channel as being available based at least in part on the first CCA procedure; and transmits a packet on the channel immediately following the completion of the first CCA procedure. A second device performs a CCA procedure on the channel using the same count-down duration if the first and second devices are associated with the same first operator. If the first and second devices are associated with different operators, the second device performs a second CCA procedure on the channel having a different count-down duration than the count-down duration of the first CCA procedure.

    Abstract: Methods, systems, devices, and apparatuses are described for a listen-before-talk (LBT) mechanism. A wireless node, e.g., a base station, may determine that a channel is available based on completing a clear channel assessment (CCA) procedure. The wireless node may be associated with a first operator. The wireless node may transmit a first message on the channel in a subframe based on the CCA procedure. The first message may include a header portion that precedes a data portion. The first message may be time aligned with a second message transmitted from a second wireless node that is associated with the first operator.
