Embodiments include methods, performed by a user equipment (UE), for transmitting information on an uplink (UL) shared channel within a cell of a radio access network. Such embodiments include receiving, from a network node serving the cell, a configured uplink grant of resources for transmitting information on the UL shared channel. The uplink grant can indicate particular timeslots during which transmission on the UL shared channel is allowed and can include: a periodicity parameter indicating an uplink periodicity for configured resources, and an allowance parameter indicating a number of timeslots, within each uplink periodicity, during which transmission on the UL shared channel is allowed. Such embodiments also include transmitting information on the UL shared channel during at least one of the particular timeslots indicated by the uplink grant. Embodiments also include complementary methods performed by a network node, and UEs and network nodes configured to perform such methods.
