Apparatus and method for synchronous multiplexing and multiple access for different latency targets utilizing thin control

An apparatus configured for wireless communication, comprising:

• at least one processor;
• a computer-readable medium communicatively coupled to the at least one processor;
• and
• a transceiver communicatively coupled to the at least one processor,
• wherein the at least one processor is configured to:
• utilize the transceiver to transmit, within a first transmission time interval (TTI), a grant of time-frequency resources for first data within the first TTI;
• utilize the transceiver to transmit the first data on the downlink data channel during the first TTI;
• configure control information to include a grant modification configured to modify the grant of time-frequency resources for the first data within the first TTI;
• and
• utilize the transceiver to transmit the control information on a downlink control channel during a second TTI shorter in duration than the first TTI and that overlaps a portion of the first TTI.
