Abstract: A triggering frame in a wireless network grants a medium to an AP for a TXOP. The frame defines RUs and allocates Uplink RUs to UL transmissions for an UL duration and Direct Link RUs to P2P transmissions. All the P2P exchanges are nested within the UL duration, hence avoiding an acknowledgment frame in the DiL RUs to interfere with a block-ack frame of the AP after the UL transmissions. This is relevant for DiL RUs adjacent, in frequency, to the other defined RUs. The block-ack frame is duplicated over the DiL RUs. The RU immediately adjacent to the DiL RUs is declared, in the triggering frame, as being unused: no non-AP station is allowed to use it during the UL duration, or even the TXOP. Such empty RU may be declared only in case the DiL transmission requires a response frame from the destination P2P station.

Abstract: The disclosure relates to a method for configuring an WLAN (Wireless Local Area Network) access point adapted to use at least one operational frequency channel to transmit or receive data when the access point is in an operational mode. The configuring includes checking an availability of at least one restricted frequency channel, a use of the restricted frequency channel being restricted by the availability, choosing the operational frequency channel from a set of frequency channels according to the checked availability, a first configuring comprising a first checking of restricted frequency channels belonging to a first proper sub-set of the set being performed before entering into the operational mode. At least one second checking of at least one restricted frequency channel of the set, that has not been checked as available, is performed after the first configuring.

Abstract: This socket, intended primarily to be mounted at the end of a mooring cable for an anchoring system of a mobile massive element, comprises a socket body 12 having an internal cavity 14 comprising a guide chamber 34 for the mooring cable 22, an intermediate section 18 and a fastening receptacle 20 intended to receive and block the ends of the strands of the mooring cable 22, and means 30, 30? for coupling with the mobile massive element to be anchored, positioned on the socket body 12 so as to define a pivoting axis 32 of the socket body 12, which axis passes through the intermediate section 18. The use of the socket in anchoring systems, especially in the offshore environment, assures natural self-alignment thereof with the cable on which it is mounted, during the diverse movements by which the anchoring system is affected.
