The invention involves management of communication resources (40, 45) in a network (1) utilizing multi-node-adapted resources (40) for transmission of multi-node-associated information and single-node-adapted resources (45) for transmission of single-node-associated information. A default resource allocation (60) specifying, for all transmitter nodes (10, 15) in the network (1), when the respective resource type is available for usage is defined. A subset (10) of the nodes in the network (1) estimates an expected amount of multi and/or single-node-associated information to be transmitted by the node subset (10). The default resource allocation (60) is then dynamically adjusted, for the node subset (10), based on the estimated expected information amount, implying that the physical resources (40, 45) defined by the default time structure (60) are dynamically shared in the frequency domain. According to the adjusted default resource allocation (65), a multi/single-node-adapted resource (40) will be allocated for transmission, by the node subset (10), of single/multi-node-associated information.
