    Abstract: A method of communication includes duplication of a first field of a first content channel into a third field in a third content channel and applying a modulation and coding scheme (MCS) to only one of the first field and the third field. The first content channel is a first portion of a frame and the third content channel is a third portion of the frame. Duplication of a second field of a second content channel into a fourth field in a fourth content channel and applying a modulation and coding scheme (MCS) to only one of the second field and the fourth field. The second content channel is a second portion of a frame and the fourth content channel is a fourth portion of the frame. The first content channel and the second content channel form a first group of content channels and the third content channel and the fourth content channel form a second group of content channels. The method then transmits the frame.

    Abstract: A directional link maintenance method and a station STA to improve accuracy and timeliness of directional link availability determined by the STA are described. In at least one embodiment, the method includes monitoring, by a first station STA, an information packet, where the information packet carries first identification information, and the first identification information is used to identify a first directional transmit beam that is used a second STA when the second STA sends the information packet; determining, by the first STA, whether the information packet is an information packet that is sent by the second STA to a third STA, and obtaining the first identification information if the information packet is an information packet that is sent by the second STA to the third STA; and determining, by the first STA, whether the first identification information matches preset second identification information.

    Abstract: The present disclosure provides methods and apparatus for coordinated beamforming. An aspect of the disclosure provides a method. The method includes sending, by a first access point (AP) of a plurality of collaborating APs, to one or more stations (STAs) associated with the plurality of collaborating APs, a request for channel state information (CSI) associated with the one or more STAs and the first AP. The method further includes receiving a response including the CSI associated with the one or more STAs and the first AP. The method further includes sending, to a second AP of the plurality of collaborating APs, a sounding request indicating the second AP to request, from the one or more STAs, CSI associated with the one or more STAs and the second AP. The method further includes sharing CSI information between the first and the second AP.

    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: A format for a Null Data Packet Announcement (NDPA) frame for Wi-Fi sensing is provided. The frame format is based on the ranging NDPA frame format. The sensing frame can indicate channel state information measurement parameters, for a preamble punctured EHT NDP PPDU, in the Common Info field of the frame. When there is insufficient space in the Common Info field, the puncturing patterns can be indicated in each station (STA) field of the frame. Alternatively, the sensing frame can include an additional Common Info field that includes the information defining the puncturing patterns. Also provided is a method that indicates partial bandwidth (BW) feedback when the BW of each STA is smaller than the BW of the EHT NDP PPDU. A method that indicates the BW of the sensing NDPA frame is also provided, as is a method for setting the signal field in the EHT NDP PPDU for a number of long training field repetition.
