摘要： In a two-way ranging scheme where a first apparatus (e.g., device) determines a distance to a second apparatus (e.g., device), specified packets are sent between these apparatuses at specified times to facilitate the determination of the distance. In some aspects, these packets may be defined and/or sent in a manner that enables the apparatuses to detect a leading edge of a received packet with a high degree of accuracy. For example, an apparatus may transmit a packet a defined period of time after transmitting or receiving another packet. In addition, a packet may comprise a defined symbol sequence that is used by an apparatus that receives the packet to identify a leading edge of the packet.

摘要： Systems and methods for controlling a delay associated with paging a remote device. In one implementation, a paging device arranges page operations such that if one of two consecutive page scans performed by a remote device occurs during a response scan, the other page scan occurs during the transmission of a page. In another implementation, a device scanning for a page arranges page scans such that if one of two consecutive page scans occurs during a page response scan, the other page scan occurs during the transmission of a page. In another implementation, a device scanning for a page performs a series of sets of separate page scans, wherein the time interval between two of separate scans in a set is less than the time interval between adjacent sets. The page scans in a set are configured to ensure that one of them occurs during the transmission of a page.

摘要： Disclosed is a method for establishing a wireless link key between a remote device and a group device. In the method, the remote device obtains a group identifier from the group device, and determines whether the group device is associated with a group having a trust association with the remote device. When the group device is determined to be associated with a group having an established trust association with the remote device, the remote device forwards a link setup request to the group device for virtually pairing with the group device using the trust association to establish the wireless link key. When the group device is determined not to be associated with a group having an established trust association with the remote device, the remote device forwards a pairing request to the group device for pairing with the group device to establish the wireless link key.

摘要： Low power wireless communication techniques may be employed in devices that communicate via a wireless body area network, a wireless personal area network, or some other type of wireless communication link. In some implementations the devices may communicate via one or more impulse-based ultra-wideband channels. Inter-pulse duty cycling may be employed to reduce the power consumption of a device. Power may be provided for the transmissions and receptions of pulses by charging and discharging a capacitive element according to the inter-pulse duty cycling. Sub-packet data may be transmitted and received via a common frequency band. A cell phone may multicast to two or more peripherals via wireless communication links.

摘要： Low latency and computationally efficient techniques may be employed to account for errors in data such as low bit-width, oversampled data. In some aspects these techniques may be employed to mitigate audio artifacts associated with sigma-delta modulated audio data. In some aspects an error may be detected in a set of encoded data based on an outcome of a channel decoding process. Upon determining that a set of data may contain at least one error, the set of data may be replaced with another set of data that is based on one or more neighboring data sets. For example, in some aspects a set of data including at least one bit in error may be replaced with data that is generated by applying a cross-fading operation to neighboring data sets. In some aspects a given data bit may be flipped as a result of a linear prediction operation that is applied to PCM equivalent data that is associated with the given data bit and its neighboring data bits. In some aspects a set of data including at least one bit in error may be replaced with data that is generated by performing linear interpolation operations on PCM equivalent data that is associated with neighboring data sets.
