  • Patent number: 11418983
    Abstract: Embodiments of the disclosure relate to a coordinator network node and one or more network access nodes interworking in a wireless communication system. The coordinator network node determines a joint resource allocation area (?UE) based on measurement messages from network access nodes. The determined joint resource allocation area (?UE) is thereafter transmitted to the network access nodes. Thereby, the coordinator network node enables to determine the portion of the first or the second service areas that are free from interference from neighbouring network access nodes where each network access node can perform resource allocations independently. It further enables to determine/identify the joint resource allocation area where neighbouring network access nodes significantly interfere each other. Therefore, e.g. resource allocation in the system can be improved. Furthermore, the disclosure also relates to corresponding methods and a computer program.
