    Abstract: Embodiments of the present disclosure relate to link based groupcast communication. In the solution, a groupcast stream can be delivered on a specified link in a negotiation manner between a first device (e.g., an access point AP in an infrastructure BSS or a mesh station in a mesh BSS) and a second device (e.g., a non-AP station in the infrastructure BSS or a mesh station in the mesh BSS). As such, the waste of radio resources caused by repeated transmission of invalid data on the multiple links are reduces significantly.

    CPC classification number: H04W74/0808

    Abstract: This document discloses a solution for decoding frames received via multiple links. According to an aspect, a method for an apparatus of a wireless network includes: decoding at least a first part of a first frame received on a first channel; detecting, during said decoding the first part of the first frame, transmission of a second frame on a second channel; in response to said detecting, buffering at least a first part of the second frame, the first part of the second frame including duration information; after said decoding the first part of the first frame, decoding at least the first part of the second frame; updating, on the basis of the duration information, channel occupation information of the second channel; starting, based at least partly on the channel occupation information of the second channel indicating that the second channel not occupied, contention for channel access on the second channel.

    Abstract: This document discloses a solution for performing internetwork beamforming cooperation. According to an aspect, a method comprises: establishing, by a first access node (112) of a first wireless network, internetwork beamforming with a second access node (110) of a second wireless network, wherein the establishment indicates at least one station (102) of the second wireless network; in response to said establishing, transmitting by the first access node (112) a channel sounding signal; receiving, by the first access node (112) from the at least one station (102) of the second wireless network, a beamforming report comprising channel state information measured from the channel sounding signal; and performing, by the first access node (112), null steering beamforming transmission in the first wireless network on the basis of the received channel state information.

    Abstract: This document discloses a solution for determining distances. In the solution, a first frame is transmitted (200) to a second apparatus; a second frame is received (202) from the second apparatus, as response to the first frame; an indication of the duration between the reception time of the first frame and transmission of the second frame is received (204); an indication whether the duration is constant or variable is received (206); and in case the duration is constant, the distance between the first apparatus and the second apparatus is determined (208) based at least partly on the indication of the duration.
