H04L 27/26
H04W 72/04
H04L 1/00

Abstract:

Methods, apparatuses, and computer readable media for a common preamble for wireless local-area networks (WLANs). An apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to encode an AP trigger frame that includes a resource allocation for other APs to transmit trigger frames to perform an uplink or downlink multi-user transmission with stations (STAs). The resource allocation includes information so that the transmissions are coordinated at the physical level to lessen interference among the APs and the stations. The processing is configured to encode a trigger frame for multi-AP request-to-send (RTS), the multi-AP trigger frame comprising for each of a plurality of APs, the trigger frame indicating that each of a plurality of APs are to transmit a physical (PHY) protocol data unit (PPDU) comprising a request-to-send (RTS) or multi-user (MU) RTS (MU-RTS).

H04W 88/08

Abstract:

Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The AP may be configurable to operate as a master AP of a multi-AP group. The master AP may establish the multi-AP group by: transmitting one or more messages to advertise the multi-AP group; and exchanging signaling with one or more of the other APs of the multi-AP group. The signaling may include at least one message related to one of the other APs joining the multi-AP group. The master AP may establish the multi-AP group to enable usage of AP Trigger Frames (AP TFs) for coordination of resources to be used for downlink transmissions of the APs of the multi-AP group.

H04L 5/00
H04W 72/04
H04B 17/309

Abstract:

This disclosure describes systems, methods, and devices related to signaling and use of multiple transmission chains. A device may determine bits indicative of eight or fewer spatial streams. The device may encode the bits by generating an indication of more than eight spatial streams. The device may determine one or more fields of a frame, the one or more fields including the encoded bits. The device may send the frame.

H04W 72/04
H04W 80/02

Abstract:

Methods, apparatuses, and computer readable media for high efficiency (HE) beacon and HE formats in a wireless network are disclosed. An apparatus of a high efficiency (HE) access point (AP), where the apparatus comprises processing circuitry configured select a tuple from the basic HE-MCS set of tuples, if a basic HE modulation and control scheme (MCS)(HE-MCS) and a number of spatial streams (NSS) set of tuples is not empty, and otherwise select the tuple from a mandatory HE-MCS and NSS set of tuples. The processing circuitry may be further configured to encode a beacon frame in a HE single user (SU) physical layer (PHY) protocol data unit (PPDU), in accordance with the selected tuple, and configure the HE AP to transmit the HE SU PPDU. Null data packets formats, methods, computer readable media, and apparatuses are disclosed for multiple 20 MHz operations.

International Classification:

G06K 9/00

Abstract:

In one embodiment, a device identifies, from image data captured by one or more cameras of a physical location, a focal point of interest and people located within the physical location. The device forms a set of nodes whereby a given node represents one or more of the identified people located within the physical location. The device represents a person queue as an ordered list of nodes from the set of nodes and adds a particular one of the set of nodes to the list based on the particular node being within a predefined distance to the focal point of interest. The device adds one or more nodes to the list based on the added node being within an angle and distance range trailing a forward direction associated with at least one node in the list. The device provides an indication of the person queue to an interface.
