Abstract: A method of communication between a first node and a second node operating in a communications network. The method includes sending, by the first node, to the second node, a first transmission to configure a communication channel between the first node and the second node. The first transmission includes a first frame including a first capability indicator. The first capability indicator indicates a first MU-MIMO capability of a transmitter of the first node. The first multi-user (MU)-MIMO capability includes a first Modulation and Coding Scheme (MCS) processable by the first node or a first number of spatial streams (NSS) processable by the first node.

Abstract: The present disclosure provides methods and apparatus related to NDPA frame indication. An aspect of the disclosure provides a method. The method includes sending, to one or more stations (STAs), a request for channel state information (CSI). The request includes a null data packet announcement (NDPA) frame including a first field and a second field. The first field indicates presence of the second field, and the second field indicates a variant of the NDPA frame. The method further includes receiving, from the one or more STAs, a CSI feedback response based on the request. In some embodiments, the first field is one of a sounding dialog token field and indicates the presence of the second field via at least two bits. In some embodiments, the first field is a frame control field and indicates the second field via a 4-bit subtype subfield.

Abstract: The AP can generate a distinctive 8 bit value, and fill the 8 most significant bits (MSBs) of the a 16 bit AID field to form a EDMG BSS AID. Beamforming can include a station performing a sector level sweep (SLS) process including transmitting, in sequence, a plurality of short sector sweep (SSW) frames to the other station using corresponding ones of the antenna sectors, and receiving, in sequence, a plurality of the short SSW frames from the other station, the short SSW frames having an addressing field format specifying a receiver address association ID (RA AID) and a transmitter address association ID (TA AID). The distinctive 8 bit value can be used as the AP AID.

Abstract: A method includes sending, by an access point (AP) to one or more stations (STAs), a request for channel state information (CSI). The request includes a null data packet announcement (NDPA) frame including a common information field. The common information field including an indicator of whether trigger based (TB) sounding or non-trigger based (non-TB) is being used. Then, the method includes receiving, by the AP from the one or more STAs, a CSI feedback response based on the request. The common information field may be a null data packet announcement (NDPA) variant field in an alternative name and the indicator may utilize 1 bit.

Abstract: The present disclosure provides for methods, systems and apparatus related to Variable High Throughput (HT) Control Field. An aspect of the disclosure provides for a method performed by a station (STA). The method includes sending, to a second STA, a message including a frame, the frame including a variable high throughput (HT) control field. The variable HT further includes a first subfield indicating an N number of control IDs, wherein N is equal to or more than one. The variable HT further includes N additional subfields. Each of the N additional subfield includes: a control identifier (ID) field and a control information field associated with the Control ID field. The method further includes receiving, from the second STA, a response.

Abstract: A method comprises, by a communications device, receiving over a network interface a sensing request transmitted by a sensing initiator, the communications device measuring the received sensing request and determining a parameter of the received sensing request, and the communications device sending over the network interface an action frame to the sensing initiator. The action frame includes a category indicative that the action frame contains a sensing response. The sensing response includes the parameter in an information element of the action frame.

Abstract: A method, apparatus and system for transmitting control information in a header of a physical protocol data unit (PPDU), such as an IEEE 802.11 compliant PPDU. Embodiments include indicating control features in an EDMG PPDU for Wireless LAN communications. The method and system may include overloading at least one bit of a Scrambler Initialization Field in the PPDU header (e.g. the PHY header) to convey control information, as well as to be used to initialize the scrambler shift register. The same header bits are thus used for both purposes. Examples of control information include a primary channel, channel width or MIMO configuration to be used in further communication.

Abstract: Aspects of the present application provide mechanisms for minimizing latency in real time application (RTA) traffic on wireless LANs. A wireless electronic device identifies real time application network packets in the Application layer, gives them a novel MPDU frame type and subtype, and maps them into a high priority access category such as AC_VO. Upon receiving a TXOP, the device preferentially transmits RTA frames before frames mapped to the access category awarded the TXOP. Additional aspects allow for pre-emptive priority transmission of RTA frames.

Abstract: Methods, systems and apparatus related to spatial modulation for WLAN (IEEE 802.11) are provided. A plurality of spatial antenna streams of modulation symbols are generated based on a dynamic mapping of a plurality of spatial streams to the plurality of spatial antenna streams. The dynamic mapping may be based on a stream of non-channel-encoded information bits, in accordance with a spatial modulation. The method may further include causing driving of a plurality of antennas based on the plurality of spatial antenna streams to transmit an IEEE 802.11 frame. The plurality of antennas may be greater in number than or equal in number to the plurality of spatial antenna streams. An IEEE 802.11 frame can include an indication that the frame was transmitted using spatial modulation. The indication may be in a subfield within a SIG field of a PHY header of the IEEE 802.11 frame.
