Abstract: Systems and methods for wireless communication are disclosed. In one aspect an access point (AP) includes a processor configured to generate a frame with an information element (IE) assigning a restricted access window (RAW) and to determine whether or not to include a field in the IE indicating a group of one or more devices allowed to transmit during the RAW based on a type of the RAW. The processing system further includes an interface to output the generated frame for transmission. According to aspects, at least one option type (e.g., Omni) of the RAW type (e.g., Simplex) is accessible by devices regardless of their device type. Accordingly, the AP may not include the field in the IE indicating the group of one or more devices allowed to transmit during the RAW for the at least one option type of RAW.
