The one or more processors may be configured to set a first subfield of the frame to indicate whether the first BSSID is the same as the second BSSID. The one or more processors may be configured to wirelessly transmit, via the transmitter over a wireless local area network (WLAN), the generated frame.

Systems and methods for ultra-wideband (UWB) in-band discovery may include a first UWB device which determines an availability for associations with potential controlees, and which generates and transmits an application control (AC) information element (IE) indicating the availability. A second UWB device may receive the AC IE, select an available slot for transmitting an association request to the first UWB device, and transmit the association request in the available slot. The first UWB device may receive the association request, generate an association response, and transmit the association response to the second UWB device.

Disclosed herein are systems and methods related to describing slot information. In one aspect, a first wireless communication device determines a bitmap having a value for each of a plurality of slots for wireless traffic. The bitmap may indicate a status or type of a corresponding slot. The first wireless communication device may send, using a wireless local area network (WLAN) based protocol, to a second wireless communication device, a message comprising the bitmap. The message may further comprise a duration of each of the plurality of slots, a period of the plurality of slots, and a persistency of the plurality of slots.

Systems and method of describing slot information

Disclosed herein are related to a wireless communication. In one aspect, a wireless communication device receives a frame including a first indication that indicates the wireless communication device to disable transmission during a quiet period. The quiet period may overlap with a restricted service period of a restricted target wake time (TWT) schedule of the wireless communication device. In one aspect, the wireless communication device may determine to ignore the first indication for the quiet period based on a defined rule or a separate indication indicating the wireless communication device to ignore the first indication.

Systems and methods for quiet element in TWT for wireless communication

A first device within a multi-link device having a plurality of wireless links including a first link and a second link, may include one or more processors configured to receive a first frame on the first link while communicating with a second device for transmission of a second frame on the second link. The one or more processors may decode a portion of the first frame to determine a first duration of no medium access. The one or more processors may determine, a second duration comprising a remaining transmission duration on the second link. The one or more processors may determine whether the first duration is greater than or equal to the second duration. In response to the first duration being greater than or equal to the second duration, the one or more processors may defer channel access on the first link until an end of the first duration.

Systems and methods of wireless medium access recovery

Disclosed herein are systems and methods directed to configuring traffic specification for wireless communication. In one aspect, a first wireless communication device may configure a bitmap indicating a plurality of traffic identifiers (TIDs) sharing a traffic specification (TSPEC) element. The first wireless communication device may send a message including the bitmap to a second wireless communication device.

Disclosed herein are systems and methods related to systems and methods of target wake time for peer-to-peer communication. In one aspect, a first wireless communication devices configures a subfield indicating to extend a restricted target wake time (rTWT) for peer-to-peer communication. The first wireless communication device sends a message including the subfield to a second wireless communication device.

Systems and method of target wake time for peer-to-peer communication

Disclosed herein are systems and methods related to using restricted target wake time in wireless communication. In one aspect, a first wireless communication device may configure 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 is to be communicated during a respective service period of a restricted target wake time (rTWT) schedule. The first wireless communication device may send a message including the first field to a second wireless communication device.

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

Disclosed herein includes a system, a method, and a device for providing enhanced distribution channel access (EDCA). A wireless device can receive, from a wireless node, an advertisement message comprising a first plurality of parameters for a plurality of time slots available for prioritized access in a wireless local area network (WLAN) to communicate data. The wireless device can send to the wireless node, a request to assign a first time slot of the plurality of time slots to the wireless device for prioritized access. The wireless device can receive, from the wireless node, a response granting access to a first time slot of the plurality of time slots. The response can indicate one or more parameters of the first plurality of parameters for the first time slot. The wireless device can access the first time slot according to the first plurality of parameters.

Systems and methods for prioritized EDCA channel access

A first wireless communication device may send, to a second wireless communication device, a request message including a traffic stream identifier (TID) and a first value, the first value indicating that a traffic stream between the first wireless communication device and the second wireless communication device and corresponding to the TID is latency sensitive. The first wireless communication device may receive, from the second wireless communication device responsive to the request message, a response message including a second value indicating whether the corresponding traffic stream between the first wireless communication device and the second wireless communication device is latency sensitive, compare the second value and the first value, determine, based on a result of the comparing, that the request message has been accepted, and communicate, with the second wireless communication device responsive to the determining, the corresponding traffic stream as a prioritized traffic stream instead of a regular traffic stream.
