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 virtual pairing of a first peer device with a second peer device. In the method, a nonce is generated at the first peer device for use in virtually pairing the first and second peer devices to establish a first-type wireless connection. The nonce is forwarded from the first peer device to the second peer device over an already established second-type wireless connection between the first and second peer devices. At least one new key is generated from the nonce and a shared key for the already established second-type wireless connection. The first peer device is virtually paired with the second peer device using the at least one new key to establish the first-type wireless connection between the first and second peer devices.

摘要： For interference control, a sector m estimates interference observed from terminals in neighbor sectors and obtains an interference estimate. Sector m may generate an over-the-air (OTA) other-sector interference (OSI) report and/or an inter-sector (IS) OSI report based on the interference estimate. Sector m may broadcast the OTA OSI report to the terminals in the neighbor sectors. These terminals may adjust their transmit powers based on the OTA OSI report. Sector m may send the IS OSI report to the neighbor sectors, receive IS OSI reports from the neighbor sectors, and regulate data transmissions for terminals in sector m based on the received IS OSI reports. Sector m may control admission of terminals to sector m, de-assign admitted terminals, schedule terminals in sector m in a manner to reduce interference to the neighbor sectors, and/or assign the terminals in sector m with traffic channels that cause less interference to the neighbor sectors.

摘要： In a signal-based gain control scheme, one or more gain levels used for processing signals are selected based on characteristics of previously received signals. For example, different gain levels may be used to receive sets of signals whereupon certain characteristics of the received sets of signals are determined. One or more gain levels are then selected based on these characteristics whereby another signal is processed based on the selected gain level(s). In some aspects, the signal-based gain control scheme may be employed to facilitate two-way ranging operations between two devices. For example, leading edge detection may involve determining a characteristic of a received signal, determining a threshold based on the characteristic, and identifying a leading edge associated with the received signal based on the threshold. In some aspects, the signal-based gain control scheme may be employed in an ultra-low power pulse-based communication system (e.g., in ultra-wideband communication devices).

摘要： In an addressing scheme for wireless communication a communication channel may be defined based on a unique identifier associated with a destination node or a source node. In addition, a short identifier may be included in messages sent over the communication channel such that a node may uniquely identify the source node or destination node for the message. A node may use a short identifier as an index into a lookup table to determine one or more parameters to be used for communicating with another node.

摘要： Device authentication is based on the ability of a human to synchronize the movements of his or her fingers. A pairing procedure for two wireless devices may thus involve a synchronization test that is based on the relative timing of actuations of input devices on each of the wireless devices. In some aspects a synchronization test involves determining whether actuations of user input devices on two different wireless devices occurred within a defined time interval. In some aspects a synchronization test involves comparing time intervals defined by multiple actuations of user input devices on two wireless devices.

摘要： A tunable delay line is calibrated to maintain the delay of the delay line at a desired value or within a desired range of values. In some aspects a signal is passed through a delay line multiple times so that the cumulative delay of the signal through the delay line (e.g., as indicated by a count) may be calculated over a period of time. The count is compared with an expected count and, based on this comparison, the delay of the delay line is adjusted as necessary. In some aspects the signal may comprise a digital signal. In some aspects a delay through a delay line may be calculated based on analysis of amplitude changes in a signal caused by a phase shift imparted on the signal by the delay line. In some aspects a delay line is incorporated into a transmitted reference system to generate and/or process transmitted reference signals.
