20100271965 | Methods and Apparatus in a Wireless Communication System - The present invention relates to methods and apparatus in a RBS and a UE for reference signal (RS) measurements in an OFDM system, that enable having a configurable RS transmission bandwidth which is smaller than the system bandwidth. This allows for better interference coordination of RS, which in turn improves the UE RS measurements used for different services such as positioning. The RBS retrieves the RS transmission bandwidth, determines a RS measurement bandwidth based on this RS transmission bandwidth, and transmits the determined bandwidth to the UE. The UE receives the RS measurement bandwidth and measures the RS in a bandwidth determined based on the received measurement bandwidth and the UE capability. | 10-28-2010 |
20110105144 | Method, apparatus and system for defining positioning configuration in a wireless network - GPS and A-GPS based positioning methods can be used to determine UE locations to enable location based services to be provided.

20110159893 | Signaling Support Enabling QoS Discrimination for Positioning, Location and Location-Based Services in LTE - One aspect of the present invention extends the number of client and/or service types used in location-based services. The extension provides richer definitions for use in selecting the optimal or otherwise best suited positioning sequences to be used in fulfilling given positioning requests. For example, some types of commercial-related positioning requests are better satisfied with quicker-but-lower-accuracy position determinations, while other types benefit from more-accurate-but-slower position determinations. These and other benefits are provided by extending the type definitions used to identify commercial positioning requests. For example, a UE may be configured to send positioning requests that indicate the extended client or service types. As another example, the network node(s) involved in generating or processing such requests are configured to understand the extended type definitions and/or to map the extended definitions to QoS requirements, or to particular positioning sequences, for requesting that a positioning node carry out that particular positioning sequence. | 06-30-2011 |

20110244879 | Method and Apparatus for use of Performance History Data in Positioning Method Selection - A method of selecting the positioning method(s) used to respond to given positioning requests uses historical performance data reflecting the actual performance yielded by one or more of the positioning methods that are generally available for selection.

In one or more embodiments, the present invention proposes a general solution whereby the receiving radio equipment is informed not only on whether muting is used in general in a cell, but also the particular timing and formatting of such muting. Further, the contemplated method provides for the use of dynamic muting patterns, and thus avoids the need for statically defined muting patterns, and provides for coordinated muting control, across two or more network cells. In at least one embodiment, static or less dynamic aspects of the muting configuration is signaled via higher-layer signaling, while lower-layer signaling is used to signal more dynamic aspects of the muting configuration. | 08-21-2014 |

20140321259 | Methods and Apparatus in a Wireless Communication System - The present invention relates to methods and apparatus in a RBS and a UE for reference signal (RS) measurements in an OFDM system, that enable having a configurable RS transmission bandwidth which is smaller than the system bandwidth. This allows for better interference coordination of RS, which in turn improves the UE RS measurements used for different services such as positioning. The RBS retrieves the RS transmission bandwidth, determines a RS measurement bandwidth based on this RS transmission bandwidth, and transmits the determined bandwidth to the UE. The UE receives the RS measurement bandwidth and measures the RS in a bandwidth determined based on the received measurement bandwidth and the UE capability. | 10-30-2014 |
