Abstract: In one aspect a wireless communications method includes sending, from a first radio terminal to a second radio terminal, a grant message to allow transmission in a future time slot, wherein the future timeslot corresponds to resources of a dummy shared channel in a first direction, and scheduling one or more resources of a shared channel in a second direction with corresponding acknowledgement that overlaps in time with the dummy shared channel in the first direction. In another aspect, a method includes receiving, at a second radio terminal from a first radio terminal, a grant message to allow transmission in a future time slot, wherein the future timeslot corresponds to resources of a dummy shared channel in a first direction, and receiving one or more resources of a shared channel in a second direction with corresponding acknowledgement that overlaps in time with the dummy shared channel in the first direction.
