1. A network node for scheduling a plurality of wireless devices with periodic preconfigured uplink shared channel resources, the network node comprising processing circuitry configured to:
configure a wireless device of the plurality of wireless devices with a preconfigured uplink resource, PUR, the PUR having a transmission length and a periodicity, the wireless device configured PUR having a periodicity derived from a set of PUR periodicities used by the network node which are multiples of a smallest PUR period;
the PUR being configured based at least in part on at least one mutliplexing criterion for multiplexing the plurality of wireless devices for PUR transmission, the at least one multiplexing criterion including:
determining a transmission length and a periodicity of a PUR transmission of each wireless device of the plurality of wireless devices;
grouping at least two of the wireless devices having PUR periodicities that are different with each periodicity of the at least two of the wireless devices being a multiple of another periodicity; and
allocating a unique starting subframe for the PUR transmission for each wireless device in the group.
