Abstract: A method for performing channel usage management with aid of multi-link operation architecture and associated apparatus are provided. The method applicable to a wireless transceiver device within a wireless communications system may include: utilizing the wireless transceiver device to communicate with another device within the wireless communications system through at least one portion of multiple links respectively corresponding to multiple predetermined radio frequency bands; and at first time point when radar is detected in a first channel used by a first link among the multiple links, starting performing a first procedure to make channel management information be received by the other device via one or more other links among the multiple links at any time point when the other device is ready to receive the channel management information, wherein the other device is not ready to receive the channel management information at the first time point.

Abstract: An attack prevention method includes: receiving an authentication request frame; and in response to receiving the authentication request frame, replying with an authentication response frame that is sent to a non-access-point (non-AP) station (STA), wherein the authentication request frame includes a timeout interval element that carries Authentication Comeback time. Another attack prevention method includes: ignoring each specific request frame that is received within a period in which a connected non-AP STA operates under a power saving mode, wherein each specific request frame includes one of an authentication request frame, an association request frame, and a reassociation request frame.

Abstract: An integrity protection method is employed by a first wireless communication device that communicates with a second wireless communication device, and includes generating a frame and transmitting the frame to the second wireless communication device. The step of generating the frame includes applying integrity protection to a control information subfield, or applying integrity protection to an operating mode field included in a frame body of the frame.

Abstract: Techniques and examples pertaining to detection and prevention of broadcast and multicast packet attacking and uncovering to disconnect attackers in CCMP or TKIP-enabled wireless communications are described. A processor of a first network device establishes a wireless communication with a second network device in a wireless network. The processor detects a broadcast or multicast attack in the wireless network. The processor then notifies the second network device of the attack with a pairwise key encrypted frame.

Abstract: The present invention applies management frame defined in IEEE 802.11 standard to a wireless distribution system (WDS) mode by adding an information element (IE) into the management frame, which enables any access point (AP) in WDS to maintain IE based on its own setting and state, then send IE via the management frame for providing state of the AP under WDS mode, determine whether a physical link (i.e., a wireless link between APs) should be established therewith based on received IE, and maintain the established physical link through the wireless management frame in a real time manner. Thus, the existence and necessity of the physical link between different APs in WDS can be determined correctly.

Abstract: The present invention is to provide a topology system of wireless network with dynamic balance comprising at least one subsidiary topology system of wireless network each having a plurality of access points and only one access point automatically becomes a root access point which operates on a channel different from others, and dynamically generates an unique derivative group ID different from others as the root access point linked with a wired network; other access points not linked with the wired network join one of subsidiary topology systems of wireless network according to loading and dataflow of the subsidiary topology systems of wireless network, and automatically become either a pure access point or an escape access point, dynamically generate an unique derivative group ID same as those linked with other root access points, and operate on a channel same as those linked with other root access points.
