    Abstract: Provided are a wireless network access method and apparatus. The method includes: in a wireless network supporting a plurality of channel access approaches, using an access point to maintain a status of a traffic-stream-based or station-based traffic connection with a station; and using the access point to negotiate with the station or transmit control information to the station and to change a channel access approach used by the traffic-stream-based or station-based traffic connection.

    Abstract: A method and system for performing low power synchronization between to communication nodes is disclosed herein. In one embodiment, a method performed by a first wireless communication node includes: determining a wake up window start time and duration of a second wireless communication node; and transmitting at least one signal to the second wireless communication node during the determined wake up window, the at least one signal comprising at least one synchronization sequence, wherein the at least one synchronization sequence is configured to enable the second wireless communication node to adjust its wake up window timing.

    Abstract: Multiple wireless devices in a network perform full duplex communication in which the transmission path and receiving path are spatially separated to allow simultaneous transmission and receiving. The wireless devices can either be controlled using a centralized, or point, coordination function or a distributed coordination function. A full-duplex wireless device senses the medium during transmission by itself and selectively continues the transmission when a signal is sensed on the medium. A full-duplex wireless device measures signal being transmitted by its transmitter and estimates parameters that can be used to cancel the contribution of the locally transmitted signal to the locally received signal concurrently being received during the transmission. The transmit antenna and the receive antenna of a full-duplex wireless device can be configured to be spatially isolated from each other to minimize interference between the antenna functions.

    Abstract: Disclosed are a method and device for receiving the radio frame. The method comprises: a first functional entity of a station detects that a channel signal intensity reaches a preset threshold, and the first functional entity starts receiving a radio frame and sends an indication that a channel detection result is busy to a second functional entity of the station; the first functional entity determines that the station is not a target station for receiving the radio frame, and sends an indication of ending up receiving the radio frame to the second functional entity; and when transmission of the radio frame ends, the first functional entity sends an indication that the channel detection result is idle to the second functional entity. The disclosure provides a reception operation processing procedure of a station having the function of discarding the radio frame while not updating a network allocation vector (NAV).

    Abstract: Provided are methods and devices for transmitting a frame in a network. The method includes: setting, by a sending station, a media access control (MAC) frame header of a MAC frame, wherein the MAC frame header includes at least one bit for indicating whether the MAC frame header adopts an optimized MAC header format, the optimized MAC frame header format referring to a MAC frame format in which only necessary frame header information is reserved (S302); sending, by the sending station, the MAC frame to a receiving station (S304). The present disclosure not only ensures correct sending and receiving of a frame, but also effectively reduces the overhead of the frame header.

    Abstract: A transmitting wireless device provides channel access information to a receiving wireless device for the receiving wireless device to make a determination of when to transmit and what transmissions parameters to use for the transmission. The channel access information may be used differently by wireless devices operating in a basic service set and an overlapping basic service set. Channel access information may include fields indicative of transmission power used, signal to noise ratio headroom available, and so on. Channel access information may be generated and transmitted at the PHY layer of an implementation, thus providing a fast delivery to the receiving wireless device.
