Abstract
The disclosure relates to cellular radio communication systems, and especially to performing a joint reception of uplink transmissions from user equipment devices UE1, UE2. A serving node and a cooperating node is described together with methods performed by each node. The serving node comprises a user equipment selector, a cooperating node selector and a radio element selector. The serving node also includes a user equipment allocator, a joint reception requester configured to order joint reception data from selected cooperating nodes, and a backhaul capacity obtainer configured to obtain a backhaul capacity of selected cooperating nodes. Especially, the radio element selector is adapted to select radio resource elements based on a determined backhaul capacity. By considering the backhaul capacity, the backhaul can be employed for joint reception without becoming overloaded. The cooperating node especially includes an element prioritizing unit configured to prioritize between data obtained from different the radio resource elements.
