Disclosed herein are systems and methods related to slot assignments to traffic streams. In one aspect, a first wireless communication device sends, to a second wireless communication device, a request message including a latency marker having a requested value. The requested value indicates that a corresponding traffic stream between the first wireless communication device and the second wireless communication device is latency sensitive. Responsive to the request message, the first wireless communication device receives, from the second wireless communication device, a response message including a response latency marker. The response latency marker includes a response value for the corresponding traffic stream. When the response value is the same as the requested value, the first wireless communication device communicates corresponding traffic stream as a prioritized traffic stream instead of a regular traffic stream, with the second wireless communication device.
