摘要:
The laser beam ablatable film of the invention includes an ablatable metallic layer arranged below a translucent protective layer that is dyed through-out. The metallic layer is connected to a contrastive colored layer by a transparent connecting layer, and the contrastive colored layer is connected to a plastic film. The entire assemblage of laminated layers can also include a self-adhesive film applied to the plastic film and the self-adhesive layer is then covered by a removable carrier material. This laminated assembly can be stamped into individual labels that can be detached from the carrier material and placed onto objects. When the ablatable foil of the invention is subjected to a laser beam surface areas of the laminated assembly appear as a mixture of colors of letters or symbols resulting from the color filter effect of the protective film.

A mobile communication station in a wireless communication network is used to measure the respective times of arrival of radio signals respectively transmitted by a plurality of radio transmitters in the network. The mobile communication station is provided with real time difference information indicative of differences between a time base used by a radio transmitter serving the mobile communication station and respective time bases used by the other radio transmitters. The mobile communication station determines, in response to the real time difference information and relative to the time base used by the radio transmitter serving the mobile communication station, a plurality of points in time at which the respective radio signals are expected to arrive the mobile communication station. For each radio signal, the mobile communication station monitors for arrival of the radio signal during a period of time after the point in time at which the radio signal is expected to arrive.

The subject matter disclosed herein relates in one particular implementation to a method, apparatus, and/or system for acquiring one or more network-based measurements at a location server from a radio access network serving a user equipment (UE). A first message may be transmitted to the UE from the location server, where the first message comprises at least one of the one or more network-based measurements. A location of the UE is capable of being determined by the UE-based at least in part on the one or more network-based measurements.

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.

Various techniques are provided for Location Services (LCS) Assistance Data broadcast, for example for implementation in LTE and LTE-A systems. The embodiments described herein may use the LPP/LPPe positioning protocol, by making use of existing unsolicited Provide Assistance Data (PAD) messages. Embodiments avoid the need to define and implement a separate broadcast Assistance Data protocol. Additional exemplary embodiments for scheduling and verifying of the broadcast Assistance Data messages are described herein.
摘要:
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.

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.
摘要:
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.
