1. A node of a cellular network, comprising:

  • an interface configured to communicate with a plurality of communication devices attached to the cellular network via a radio link, andat least one processor configured to allocate first reoccurring time-frequency resources to some of the plurality of communication devices that are assigned to a first set and on the radio link of the cellular network to a first relaying channel, the first relaying channel being established via a first relaying node and between an access point node of the cellular network and the some of the plurality of communication devices that are assigned to the first set,wherein the at least one processor is further configured to allocate second reoccurring time-frequency resources to some of the plurality of communication devices that are assigned to a second set and on the radio link of the cellular network to a second relaying channel, the second relaying channel being established via a second relaying node and between the access point node of the cellular network and the some of the plurality of communication devices that are assigned to the second set,wherein at least one of the first relaying node or the second relaying node is a user equipment (UE) selected from the plurality of communication devices,wherein the first reoccurring time-frequency resources are shared between the communication devices assigned to the first set such that collision may occur between multiple communication devices of the first set attempting to transmit at the same time-frequency resource,wherein the second reoccurring time-frequency resources are shared between the communication devices assigned to the second set such that collision may occur between multiple communication devices of the second set attempting to transmit at the same time-frequency resource,wherein the at least one processor is configured to receive, via the interface, a connection message, the connection message indicating a given one of the plurality of communication devices,wherein the at least one processor is configured to assign the given one of the plurality of communication devices to the first set or the second set in response to receiving the connection message,wherein the connection message further indicates at least one element selected from the group comprising;

    a Machine Type Communication functionality of the given one of the plurality of communication devices; and

    a traffic pattern of the given one of the plurality of communication devices, wherein the traffic pattern corresponds to a periodicity or frequency of occurrence with which data to be transmitted is expected to occur, a size of individual data blocks to be transmitted, an overall size of data, or peak times for data to be transmitted; and

    wherein the at least one processor is configured to assign the given one of the plurality of communication devices to the first set or the second set depending on the indicated at least one element.
