1. An apparatus comprising:
a processor configured to cause an Access Point (AP) to:
process a capability element from a non-AP station (STA), the capability element comprising a support subfield set to a predefined value to indicate that the non-AP STA supports a restricted Target Wake Time (TWT) Service Period (SP) operation;
set a 3-bit subfield in a request type field to a predefined value of 4 to indicate a restricted TWT SP for latency sensitive traffic;
transmit a broadcast TWT element to announce the restricted TWT SP, wherein the broadcast TWT element comprises the request type field and a control field before the request type field, the control field comprising a broadcast subfield, the broadcast subfield comprising a predefined broadcast subfield value to indicate the broadcast TWT element is to announce a broadcast TWT SP as the restricted TWT SP; and
schedule communication of latency sensitive traffic for the non-AP STA during the restricted TWT SP; and
a memory to store information processed by the processor.
