  • Patent number: 9807686
    Abstract: A method for communication in a wireless telecommunications system is provided. The method comprises performing, by a UE, responsive to the UE being engaged in an emergency service, at least one neighbor cell measurement regardless of a value of an RSRP in relation to a cell measurement parameter and regardless of a configuration status of the cell measurement parameter.

  • Patent number: 9578531
    Abstract: The present disclosure provides for methods and systems for indicating a frequency for reporting a GERAN CGI. These include the relaxation of the single measurement object per frequency principle; an indication of ARFCN for CGI reading; measurement interruption avoidance; implicit indications of ARFCN for CGI reading; the use of a different object than a measurement object to report the cell for which to report the CGI; the use of a measurement configuration report to indicate the CGI cell or the selection of an ARFCN using to find rules at the UE.

  • Patent number: 8934339
    Abstract: A method and apparatus for enhancements for de-prioritization by RRC connection reject, where the enhancements relate, in one aspect, to faster cell reselection to prevent possible service outages. In a further aspect the enhancements relate to release, suspension or resumption of de-prioritization upon PLMN selection. In a further aspect, the enhancements relate to conflict handling with a CSG cell priority. In a further aspect, the enhancements relate to connected mode UE handling. In a further aspect, the enhancements relate to cancellation of a de-prioritization request.

  • Patent number: 8365050
    Abstract: Methods and systems are disclosed for decoding digital data received by a correspondent device over a communication channel. The data includes a component corresponding to a plurality of values unknown to the correspondent device and a component corresponding to one or more values known a priori by the correspondent device. To perform decoding, the correspondent device retrieves from memory at least one of the one or more known values. The correspondent device then applies a statistical measure using the known value(s) to estimate the location of the component corresponding to the one or more known values. The one or more known values and the estimated location of the component corresponding to the one or more known values are then used to assist in decoding the data.
