Mechanisms are provided for configuring a group of wireless devices capable of communicating with each other over a short-range connection and configured to communicate with a network node over a long-range wireless connection at respective predefined occasions. A method is performed by the network node. The method includes obtaining information that the wireless devices are candidates for being grouped together. The method further includes grouping the wireless devices into the group of wireless devices by distributing the predefined occasions within the group of wireless devices such that all the predefined occasions, for all the wireless devices in the group of wireless devices, do not fully overlap in time. The method further includes transmitting information indicative of the distributed predefined occasions to the wireless devices in the group of wireless devices, thereby configuring the group of wireless devices.
