| 20090258658 | Location Services Based on Positioned Wireless Measurement Reports - Methods and apparatuses are provided that may be implemented in a wireless signaling environment to provide certain location services. The location services may, for example, be based at least in part on positioning information associated with positioned wireless signaling measurements associated with wireless terminals. The location services may comprise location using signal pattern matching, location using observed timing differences, location using fine time assistance, location of significant network events and location distribution of terminals over a certain coverage area. | 10-15-2009 |
| 20090309790 | Methods and Apparatuses For Requesting/Providing Code Phase Related Information Associated With Various Satellite Positioning Systems In Wireless Communication Networks - Methods and apparatuses are provided that may be used by one or more devices within in wireless communication network to request and/or provide code phase related information signals associated with various Satellite Positioning Systems (SPSs). | 12-17-2009 |
| 20100013701 | Methods And Apparatuses For Requesting /Providing Assistance Data Associated With Various Satellite Positioning Systems In Wireless Communication Networks - Methods and apparatuses are provided for use by devices within in wireless communication network to request and/or provide assistance data and/or other like data associated with various Satellite Positioning Systems (SPSs). | 01-21-2010 |
| 20100013702 | Methods and Apparatuses For Requesting/Providing Sensitivity Assistance Information Associated with Various Satellite Positioning Systems in Wireless Communication Networks - Methods and apparatuses are provided for use by devices within a wireless communication network to request and/or provide sensitivity assistance information signals associated with one or more Satellite Positioning Systems (SPSs). | 01-21-2010 |
| 20100279707 | TIME OF ARRIVAL (TOA) ESTIMATION FOR POSITIONING IN A WIRELESS COMMUNICATION NETWORK - Techniques for determining time of arrivals (TOAs) of signals in a wireless communication network are described. Each cell may transmit (i) synchronization signals on a set of contiguous subcarriers in the center portion of the system bandwidth and (ii) reference signals on different sets of non-contiguous subcarriers distributed across the system bandwidth. A UE may determine TOA for a cell based on multiple signals transmitted on different sets of subcarriers. The UE may perform correlation for a first signal (e.g., a synchronization signal) from the cell to obtain first correlation results for different time offsets. The UE may perform correlation for a second signal (e.g., a reference signal) from the cell to obtain second correlation results for different time offsets. The UE may combine the first and second correlation results and may determine the TOA for the cell based on the combined correlation results. | 11-04-2010 |
| 20100309057 | Mobile-Based Positioning With Non-Conforming Use Of Assistance Data - Apparatus and methods for performing mobile-based positioning in a wireless communications system are presented. A position estimate is computed based on assistance data intended for a first position method. The mobile device ignores if a second positioning method is not specifically supported by a network and computes a position estimate using the second position method and a subset of assistance data intended for the first positioning method, which is supported by the network and is different from the second positioning method. | 12-09-2010 |
| 20110098057 | METHOD AND APPARATUS FOR SUPPORTING POSITIONING FOR TERMINALS IN A WIRELESS NETWORK - Techniques for supporting positioning for terminals in a wireless network are described. In an aspect, positioning may be supported by a location server that can reside in different entities. In one design, the location server may obtain positioning information (e.g., measurements) for a target device via a common positioning protocol. The location server may use the common positioning protocol regardless of where it resides and may communicate with other entities via this protocol. The location server may determine location information (e.g., a location estimate) for the target device based on the positioning information. In another aspect, positioning may be supported by transporting multiple positioning messages together. In yet another aspect, positioning may be supported by transporting a positioning message containing multiple parts defined by different organizations. In yet another aspect, positioning may be supported with shared measurement data units and/or shared assistance data units that may be applicable for different positioning methods. | 04-28-2011 |
| 20110187589 | GLOBAL NAVIGATION SATELLITE SYSTEM - Each of a first and a second navigation satellite system (NSS) are adapted to operate according to a first and a second specification, respectively, and each includes a first and a second plurality of satellite vehicles (SV), respectively. Each of the first and the second plurality of SVs are adapted to be identified by a first and a second plurality of unique corresponding identifications (IDs), respectively. A processor is adapted to receive and identify a first plurality of corresponding signals transmitted from the first plurality of SVs in response to the first plurality of unique corresponding IDs. The processor is adapted to receive and identify a second plurality of corresponding signals transmitted from the second plurality of SVs in response to the second plurality of unique corresponding IDs. The processor is adapted to determine position location information in response to receiving and identifying the first plurality of corresponding signals and the second plurality of corresponding signals. | 08-04-2011 |
