    摘要: Various operations may be performed based on a distance-related function associated with two or more devices. For example, an association procedure for two or more devices may be based on one or more determined distances. Similarly, presence management may be based on one or more determined distances. A distance-related function may take various form including, for example, a distance between devices, two or more distances between devices, a rate of change in a relative distance between devices, relative acceleration between devices, or some combination of two or more of the these distance-related functions.

    摘要: Processing may be performed by a first device (104) on behalf of a second device (102) to offload processing from the second device. In some aspects a device from which processing has been offloaded may be advantageously adapted to consume less power, have a smaller size, and have less complexity. Offloaded processing may be employed to enable a first device to process data for transmission and then send the data to another device for processing. Offloaded processing may be employed to enable a first device to process data on behalf of a second device and then send the processed data to the second device. In some aspects the data may be waveform encoded for wireless transmission between the devices. Offloaded processing may be implemented in a static manner or in a dynamic manner.

    摘要: For position determination with peer-to-peer communication, a target terminal (120a) broadcasts a request for assistance in determining its position (1). At least one ranging terminal (120b, 120c, 12On) receives the request. Each ranging terminal (120b, 120c, 12On) sends a response with a time of arrival (TOA) measurement for the request and the position of the ranging terminal (3). For two-way peer-to-peer, the target terminal receives at least one response from the at least one ranging terminal, obtains a TOA measurement for each response, estimates the distance to each ranging terminal based on the TOA measurement for the request and/or the TOA measurement for the response, and computes a position estimate for itself based on the estimated distance and the position for each ranging terminal (4). For one-way peer-to-peer, a network entity receives at least one response from the at least one ranging terminal, computes a position estimate for the target terminal, and sends the position estimate to the target terminal.

    摘要: A system and method for adaptively controlling the encoded data rate in a data compression system. The system and method sets up alternative encoded bit streams for each segment of data and selects the alternative that would produce the bit rate closest to a predetermined target bit rate for transmission. Each segment of the video input is quantized by a set of quantizers (20a-20c) to produce a plurality of quantized segments. Each quantized segment is variable rate encoded by a variable-length encoder (22a-22c) based on a quantization index to produce an alternative encoded bit stream. A set of rate measurers (24a-24c) measure the data rate that would be required to transmit each alternative encoded bit stream, and comparator (30) compares the measured rates with a predetermined target bit rate. The encoded bit stream having a rate closest to the target bit rate is provided to a rate buffer (34) in preparation for transmission. Having processed one segment of data, the system and method then updates its parameters for processing the next segment of data. A target bit rate update element (38) determines an updated target bit rate based on the rate buffer status. In addition, a quantization index update element (36) generates new quantization indices for processing the next segment of data.
