1. A method, comprising:determining, by a network node, that downlink communication is to be scheduled for transmission to user equipment;
scheduling the downlink communication;
scheduling uplink communication, wherein the uplink communication is transmitted by the user equipment to the network node, and wherein the scheduled uplink communication and the scheduled downlink communication are transmitted at a same time such that (1) uplink frequency resources given in downlink control information are the same as downlink frequency resources given in the downlink control information, or (2) uplink frequency resources given in the downlink control information are contained within downlink frequency resources given in the downlink control information; and
based on the network node determining that the downlink communication is to be scheduled, signaling the user equipment, in downlink control information, to ignore a carrier sensing mechanism, wherein the user equipment transmits the uplink communication at a time specified by the network node.
