  • Publication number: 20140228064
    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: 20140141788
    Abstract: Dynamic metro cell location planning is provided within the wireless communication coverage area of a macro cell. Metro cell location planning can include obtaining performance parameters associated with the macro cell and evaluating coverage parameters of the macro cell. Metro cell location planning can also include selecting, based on the performance parameters and the coverage parameters, a location within a wireless communication coverage area of the macro cell for placement of the metro cell. The selected location can be conveyed to a user and/or entity for deployment of the metro cells. Metro cells can be used by a carrier to fill a coverage hole and/or to offload capacity hot-spots within the network.

  • 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.

  • Patent number: 8494557
    Abstract: Systems and techniques for determining the location of user equipment (UE) in a wireless network are disclosed. These techniques leverage geometric calculations 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 with minimal real time computation. In an aspect, the target UE time value can be search 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. Further, the data can be leveraged to correct timing in the network.
