Abstract: Method for managing a wireless passive optical network, including a plurality of access points, APs, and a plurality of customer premises equipments, CPEs. The method includes configuring an AP to CPE association based on a load balancing algorithm such that each CPE is associated with at least one AP; configuring for each AP an AP beamforming codebook based on the configured association, wherein the AP beamforming codebook includes entries, wherein each entry is representative for a beam pattern to be transmitted by the AP, and wherein the AP beamforming codebook includes for each CPE associated with the AP—a line of sight, LoS, entry representative for a beam pattern to be transmitted to the respective CPE via a LoS path; and at least one back-up entry representative for a beam pattern to be transmitted to the respective CPE via a back-up path different from the LoS path.

Abstract: According to an example aspect of the present invention, there is provided a method, including receiving, by a wireless device of a first wireless network, a control request frame from a second access node of a second wireless network, the control request frame including at least a number of nulls for the wireless device. The wireless device selects a subset of antenna elements, wherein the number of antenna elements is in accordance with the number of nulls for the wireless device, and the antenna elements are selected based on reception powers of antenna elements of at least a frame from a first access node of the first wireless network and/or the second access node of the second wireless network. The wireless device transmits a control response frame with the selected antenna elements, and a data frame to the first access node with the selected antenna elements.

Abstract: Method for channel contention and data frame transmission in a wireless network. Said method for an apparatus of a first wireless network comprises: operating the apparatus on at least a first channel and a second channel of the first wireless network; while performing said operating in a first operating mode to transmit a first data frame to a receiver apparatus of the first wireless network, contending (202) simultaneously on both the first channel and the second channel and transmitting (206, 208) the first data frame on the one of the first channel and second channel where said contending is first successful; switching from the first operating mode to a second operating mode; while operating in the second operating mode to transmit a second data frame to the receiver apparatus, contending (212) simultaneously on both the first channel and the second channel and transmitting (216, 218, 220) the second data frame to the receiver apparatus according to the following conditions: in response to successful contention on the first channel before successful contention on the second channel, transmitting the second data frame to the receiver apparatus on the first channel; and in response to successful contention on the second channel before successful contention on the first channel, transmitting the second data frame on the second channel if the contention becomes successful also on the first channel or if the first channel is reserved to an apparatus of a second wireless network different from the first wireless network while the second data frame is transmitted.

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.
