  • OPTIMIZING USAGE OF A COORDINATED SERVICE
    Publication number: 20200396706
    Abstract: In some embodiments, a network node (e.g., a base station) collects information pertaining to components that form a Maximum Received Timing Difference (MRTD). For instance, the network node determines TAE. The network node then evaluates, for a particular UE, whether a certain MRTD requirement (MRTDR) for a specific coordinated service (CS) can be fulfilled. If the requirement can be met, then the network node may initiate the specific CS for the UE (or continue providing the CS), and if the requirement cannot be met, then the network node may stop or modify the CS for the UE.

  • NETWORK NODE AND METHOD FOR MANAGING POWER OF CELL REFERENCE SYMBOLS
    Publication number: 20200359337
    Abstract: A method performed by a network node for managing power of Cell Reference Symbols, CRS, wherein the network node operates one or more cells and the network node is configured to transmit the CRS in a first power mode. When the network node identifies a first cell which is not actively serving any UEs, which cell is also referred to as an empty cell, the network node reduces the power of the CRS in the first cell in relation to the first power mode. By reducing the power of the CRS, the overall interference of the CRS from the empty cell is reduced, thereby enhancing the performance in cells actively serving UEs.
