    Abstract: This document discloses a solution for enabling spatial cooperation in a hidden node scenario. According to an aspect, a method comprises: detecting, by a station of a first wireless network managed by a first access node, that a second access node of a second wireless network is hidden to the first access node; in response to the detecting, transmitting by the station a spatial cooperation request message to the second access node; receiving, by the station from the second access node as a response to the spatial cooperation request message, a spatial cooperation response message comprising at least one information element acknowledging spatial cooperation; after receiving the spatial cooperation response message, receiving by the station a frame from the first access node while the second access node is transmitting another frame and while null steering is performed between the apparatus and the second access node.

    IPC: H04W74/0808

    Abstract: A transmitter is configured to set a counter to a starting value, sense whether a channel is busy or idle and to update the counter value during sensing. When there is data to be transmitted, the transmitter is configured to determine, based on at least the counter value at a transmit opportunity and a duration the channel has been sensed idle before the transmit opportunity, whether to transmit the data or to continue the sensing the channel to a next transmit opportunity without resetting the counter value to the starting value.

    Abstract: This document discloses a solution for sharing a transmission opportunity in a wireless network. According to an aspect, a method for an apparatus of a first wireless network includes determining a plurality of devices of a second wireless network for null steering; transmitting a trigger frame, the trigger frame indicating a transmission period for data frame transfer between the apparatus and another apparatus of the first wireless network, a spatial reuse opportunity for the second wireless network during the transmission period, and an additional period preceding the transmission period; receiving, from at least one device of the second wireless network during the additional period, a channel state frame; and performing, based on the channel state frame, null steering towards the at least one device during the transmission period.
