Abstract

Method and Apparatus thereof for coordinating a joint transmission between a plurality of cooperative access nodes serving a plurality of user terminals in a mobile communications system, including the steps of: receiving channel information by said access nodes from user terminals that are being served by said access nodes; exchanging between said access nodes of said received channel information thus ensuring that all channel information is distributed to all cooperative access nodes; processing all received channel information by each one of said access nodes, and determining by said access nodes using said processed channel information, of a channel estimation for said joint transmission.
