1. A method performed by a first radio network node for handling communication in a wireless communication network, the method comprising:
transmitting, to a second radio network node, a request for retrieval of an update indication of measurement upon a potential resource aggregation of one or more cells controlled by the second radio network node; and
receiving the update indication from the second radio network node in response to the request, wherein the update indication includes resource status updates for at least one of the cells controlled by the second radio network node, wherein each resource status update for a cell is one of the following:
a list of cells controlled by the second radio network node that can be used for carrier aggregation and/or multi-connectivity for a user equipment (UE) handed over to that cell;
an index representing the availability of potential resources of the one or more cells when the overall set of resources is the one achievable via carrier aggregation and/or multi-connectivity among a group of cells for a UE handed over to that cell;
a list of cells and respective indexes representing the availability of potential resources of the one or more cells when the overall set of resources is the one achievable via carrier aggregation and/or multi-connectivity among a group of cells for a UE handed over to that cell;
an indication of the cells that can be used for carrier aggregation and/or multi-connectivity in a downlink (DL) direction, in an uplink (UL) direction, or in both DL and UL directions; or
an indication of a multi-connectivity type supported for that cell.
