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.
