    摘要： A method and apparatus for determining a location of a wireless device within an environment. A wireless device, which is operable in a wireless communication system, comprises a transmitter for transmitting a first signal to a transponder, where the transponder operates independent of the wireless communication system. The wireless device further includes a receiver for receiving a second signal from the transponder, where the second signal includes identifying data associated with the transponder. The wireless device further includes a processor for determining a location of the wireless device within the environment or classifying the environment based at least in part upon the received identifying data.

    摘要： In systems which transmit both GSM modulated and EDGE modulated signals, time of arrival estimations can be improved without requiring the detection of the type of modulation used on the received signal. In accordance with the present invention, a received signal is initially demodulated by a receiver in accordance with a first demodulation scheme. The demodulated signal is split into two copies. Taking into account the initial demodulation, one of the copies is demodulated in accordance with another demodulation scheme, thereby resulting in a first signal demodulated in accordance with the first demodulation scheme and a second signal demodulated in accordance with a second demodulation scheme. A training sequence is used to correlate the two signals which are then summed in a incoherent integration process. The result of the incoherent integration is used to estimate the time of arrival of the received signal.

    摘要： A method and apparatus are disclosed for determining more accurately, in a radio environment with time dispersion, the distance between a radio receiver and radio transmitter, by special processing of received radio signals that have been transmitted repeatedly from the same radio transmitter and are possibly subject to multipath propagation. The Time of Arrival (TOA) of the received radio signals is repeatedly estimated using channel power profiles. A TOA value near the minimum occurring TOA is selected wherein each estimated TOA is derived from incoherent integration of a randomly chosen number of the received bursts having the same known bit sequence, in order to eliminate the influence of noise.

    摘要： In a particular embodiment, a method includes receiving a first set and a second set of location data at a mobile device. The method includes locating a first reference point identifier that is included in the first set of location data and a second reference point identifier that is included in the second set of location data. The first reference point identifier field and the second reference point identifier field identify a common reference point. The method includes identifying first information in the first set of location data that is associated with the common reference point. The method also includes identifying second information in the second set of location data that is associated with the common reference point and spatially aligning the first set of location data with the second set of location data based on the common reference point to associate the first information with the second information.

    摘要： For a call flow to perform position determination, a network sends to a user equipment (UE) an indication (e.g., a request for permission) to perform a position fix for the UE. The UE responds by sending to the network an acknowledgment (e.g., a grant of permission) to perform the position fix. The UE selectively sends a position estimate for itself to the network, typically along with the acknowledgment. The network may initiate location processing if (1) a location estimate is not received from the UE or (2) a location estimate is received from the UE but the network decides not to use this location estimate. In this case, the network and the UE perform location processing to obtain a position fix for the UE. However, if a location estimate is received from the UE and the network decides to use the location estimate, then the location processing is bypassed or short circuited.

    摘要： Techniques for transferring new capability information in an efficient and backward compatible manner are described. A user equipment (UE) may send a new compatibility indicator to a wireless network to indicate that the UE has new capability information to send. This new capability indicator may be implemented with a spare bit in an information element included in an initial message sent to the network. The network may request for the information or indicate that it can receive the information. The UE may then send the new capability information to the network upon receiving the request or the indication. Alternatively, the network may convey that it supports transfer of new capability information, e.g., via a broadcast message or a unicast message. The UE may then send new capability information at any time to the network, without having to send the new capability indicator.
