1. A method, implemented by a wireless communication device, comprising:
receiving Radio Resource Control (RRC) signaling indicating that Hybrid Automatic Repeat Request (HARQ) information for data transmissions by the wireless communication device is conveyed on a Physical Downlink Control Channel (PDCCH);
transmitting data over an asynchronous protocol on an uplink carrier to a radio node of a wireless communication network;
monitoring the PDCCH for HARQ information conveyed by a New Data Indicator (NDI) flag of a transmission from the radio node, the NDI flag supporting two states, wherein a first of the two states indicates, by the NDI flag not being toggled, that the transmission comprises an uplink grant for retransmission of the data, and a second of the two states indicates, by the NDI flag being toggled, that the transmission comprises an uplink grant for new data;
receiving the transmission on the PDCCH in response to the monitoring; and
transmitting the new data or retransmitting the data based on whether or not the NDI flag is toggled, respectively, wherein the transmitting or retransmitting is to the radio node.
