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: A method for generating channel state information (CSI). The method includes determining the maximum amplitude of the real and imaginary parts of each element of a channel matrix, converting each maximum amplitude to a fixed-point value within a predefined range, determining a bit-shifting number for each maximum amplitude by comparing each fixed-point value with a series of predefined threshold values within the predefined range, quantizing the real and imaginary parts of each element of the channel matrix to an integer, and bit-shifting each of the quantized real and imaginary parts of each element of the channel matrix towards the most significant bit (MSB) by the corresponding bits and truncating the bit-shifted result to a predefined number of bits for generating channel state information (CSI) for use in communication.

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: 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: 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 for an access point to schedule obtaining frames from stations connected thereto is provided. Real-time applications provide frames and frame due dates to the stations. The frames and their due dates are stored in respective buffers of the stations. Each station identifies the earliest due date of all its buffered frames and provides the earliest due date to the access point. The access point orders the due dates and schedules the stations according to the order of the due dates. The access point then communicates with the stations according to the schedule and obtains the frames. A WLAN system implementing the method is also provided.

Abstract: Efficient and accurate sensing measurements and reporting with multiple responders in 60 GHz WLAN is accomplished by conducting the measurements and reporting in multiple sub-channels separated in a frequency domain, or in a space domain, or both. Measurements, via sensing PPDUs, can be transmitted in parallel in time by multiple devices. Messaging related to communicating reporting of sensing results can also be transmitted in parallel in time by multiple devices. This parallelization is facilitated by the use of the multiple sub-channels in frequency or spatial domain.
