  • Patent number: 12341641
    Abstract: A user equipment (UE) is configured to enhance Demodulation Reference Signals (DM-RS) in order to reduce the Peak-to-Average Power Ratio (PAPR) to the same level as for data symbols. To accomplish this function, the UE obtains a first initialization value that is calculated based on one of a first parameter (e.g., cell ID) and a second parameter and a scrambling code ID. The UE then maps the first initialization value to either a first Code Division Multiplexing (CDM) group or a second CDM group based on the scrambling code ID. The mapping associates the first initialization value with the first or second CDM group such that the initialization value is used when generating a demodulation sequence for that CDM group.

  • Patent number: 12335860
    Abstract: A method for cell reselection by a non-Bandwidth reduced Low complexity (non-BL) wireless device camped in a standalone-cell providing enhanced coverage to the wireless device. The method includes determining, based on a respective signal strength of each of a plurality of cells, a first ranking of the plurality of cells. The plurality of cells include at least the standalone cell and a target cell. While the non-BL wireless device is camped in the standalone cell with enhanced coverage, the non-BL wireless device determines that at least one criteria is met for a cell reselection from the standalone cell to the target cell offering normal coverage to the non-BL wireless device. The non-BL wireless device selects the target cell to camp in whether or not the target cell ranks higher than the standalone cell in the first ranking.
