Patent number: 11785568Abstract: 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.Type: GrantFiled: November 19, 2018Date of Patent: October 10, 2023Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Magnus Sandgren, Garry Irvine, Walter Müller, Christer Östberg, Torgny Palenius

Patent number: 11616622Abstract: A method performed by a network node for managing transmission 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 bandwidth mode. When the network node has identified a cell which is not actively serving any UEs, also referred to as an empty cell, the network node applies a reduced CRS bandwidth mode in the first cell in relation to the first bandwidth mode. By applying a reduced CRS bandwidth mode in the empty cell, the overall interference of the CRS from the empty cell is reduced, thereby enhancing the performance in cells actively serving UEs.Type: GrantFiled: April 21, 2020Date of Patent: March 28, 2023Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Tomas Lagerqvist, Walter Müller, Christian Skärby
