Abstract

The present invention relates to communication between collaborative nodes configured to collaboratively communicate in a radio network. A corresponding method comprises: sending, by each active node of the set of collaborative nodes, an RTS message for the same transmission slot; sending, by one of the active nodes, referred to as coordinator node, a CTS message to acknowledge reservation of said transmission slot on behalf of all the active nodes, upon receiving the RTSs; wherein the transmission slot is divided, based on the sent RTSs, into sub-slots for respective active nodes to transmit data packets. The invention provides an improved use of the reserved transmission slot, and a reduced waste of reserved time.
