Apparatus and method for signalling are provided. The solution includes reserving resources for communication of a set of nodes (114, 116, 118) organized into one or more scheduling groups having a predetermined group identity, each node in a scheduling group having a unique identity. Scheduling messages are transmitted to all nodes, the messages including the group identity designating the scheduling group the message is intended, an information element indicating identity of the node allowed to transmit, a bitmap indicating identities of nodes instructed to receive, and information on parameters needed to transmit and receive data utilising the resources allocated for communication. |
