Systems and methods of using restricted target wake time in wireless communication

A first wireless communication device comprising:

• at least one processor configured to generate a message including a first field indicating (i) one or more traffic streams that are latency sensitive, and (ii) a direction of each of the one or more traffic streams between the first wireless communication device and a second wireless communication device, each of the one or more traffic streams to be communicated during a respective service period of a restricted target wake time (rTWT) schedule;
• and
• a transceiver configured to send the message including the first field to the second wireless communication device,
• wherein the first field includes a first bitmap indicating one or more traffic identifiers that correspond to one or more latency sensitive traffic streams in a first communication direction from the first wireless communication device to the second wireless communication device, and a second bitmap indicating one or more traffic identifiers that correspond to one or more latency sensitive traffic streams in a second communication direction from the second wireless communication device to the first wireless communication device.
