1. A method comprising:
generating, by a first wireless communication device, 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
sending, by the first wireless communication device to the second wireless communication device, the message including the first field,
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.
