  • Publication number: 20140029521
    Abstract: Scrambling code conflicts can be mitigated by primary scrambling code reuse that minimizing a potential interference Primary scrambling codes are applied to a first set of cells located in a portion of the network being considered. A second set of cells are evaluated for primary scrambling code reuse based on a distance parameter and/or a coverage area. If the distance parameter is greater than a defined distance, primary scrambling code reuse can be applied. If all distance parameters evaluated are less than the distance parameter, a length of the distance parameter is reduced and the distance between cells is reevaluated.

  • Publication number: 20130288711
    Abstract: A location of user equipment (UE) in a wireless network is determined. Geometric calculations are leveraged for an overlaid bin grid framework mapping the wireless network area to store differential values for each frame of the bin grid framework for each pair of relevant NodeBs. A timing offset can be determined, such that when a time value from a target UE is accessed, the location can be quickly determined. The target UE time value can be searched for in the pre-computed differential value data set indexed by a relevant NodeB site pair to return a set of frames (forming a hyperbola between the site pair) that can be intersected with a second set of frames for a second NodeB site pair for the same UE. The intersecting frames can represent the location of the UE in the wireless network and timing in the network is correctable based on the data.
