Abstract:
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.
Abstract:
Techniques for transferring new capability information in an efficient and backward compatible manner are described. A user equipment (UE) may send a new capability 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.
Abstract:
Techniques for supporting eCalls are described. In an aspect, an eCall indicator may be used to indicate an eCall being established. In one design, a terminal may generate a message including an eCall indicator and may send the message to originate an eCall. The eCall indicator may indicate (i) whether or not a call is an eCall or (ii) whether an eCall is initiated automatically by the terminal or manually by a user. In another aspect, a terminal may avoid sending signaling for mobility management and connection management to wireless networks except for eCalls and designated calls. The terminal may avoid performing location updating, performing registration, responding to paging requests, etc. The terminal may exchange signaling with a wireless network for an eCall initiated by the terminal. After the eCall is initiated, the terminal may perform location updating with the wireless network and call establishment for the eCall.

Abstract:
Apparatus and methods for determining a location estimate of a mobile device based on an extended set of assistance data are presented. The extended assistance data includes assistance data for base stations, such as cellular base stations and access points, not expected to be viewable by the mobile device in a (current) first geographical area but expected to be viewable by the mobile device in a (future) second geographical area. By seeding the mobile device with assistance data expected to be useful in the future, the network reduces messaging between the network and mobile device and battery consumption by the mobile device.
Abstract:
Techniques for supporting location services with a streamlined location service layer are described. In one design, a terminal may receive a location service request from an application that is internal or external to the terminal The terminal may exchange at least one message with a location server to establish an extended location session of a particular duration via the streamlined location service layer. The terminal can thereafter obtain location service from the location server at any time within the particular duration of the extended location session, e.g., whenever a location request is received from the application. The terminal may obtain location service any number of times and at any time during the extended location session. The terminal or application may emulate a more complex location service based on location information received from all of the times in which location service is obtained by the terminal.

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).
Abstract:
In an aspect, a generic positioning protocol (GPP) may be used to support satellite-based positioning methods and terrestrial-based positioning methods for different access types. A tenninal may exchange a first GPP message with first information for a positioning method and an access type supported by GPP. The terminal may exchange a second GPP message with second infonmation for the positioning method and the access type. Each GPP message may include at least one position element, and each position element may be for a specific positioning method. The tenninal may obtain a position estimate for itself based on the second information. In another aspect, positioning may be performed based on measurements for cells of different wireless access types. In yet another aspect, received transmission times may be transformed to converted times based on common timing, which may be applicable for multiple wireless access types.
Abstract:
Briefly, in accordance with one embodiment, a method of transmitting signals is provided. Signal waveforms are transmitted from at least two respective sectors. The at least two respective sectors are from at least two different sets of a superset of sectors. The transmitted signal waveforms include signal waveforms at least nearly mutually orthogonal at least along a particular signal dimension. An advantage of such an embodiment, for example, is reduced signal interference.
Abstract:
Techniques for supporting network independent location services (LCS) are described. In one design, a location center may communicate with a terminal to establish an account for the terminal with the location center for location services. The location center may establish the account for the terminal independent of a home network or a serving network for the terminal. During signup to establish the account, the location center may (i) provide address information for the location center, security information, and/or other information for the location center and (ii) receive public identity information and/or other information for the terminal. The location center may thereafter provide location services to the terminal based on the established account and without interacting with the home or serving network for the terminal. Techniques for supporting delivery of assistance data are also described.
