Claim of US Patent No. 10,397,980

14. A node configured for electing a coordination node in a Coordinated Multipoint (CoMP) set of cooperating nodes for receiving channel information from a plurality of wireless devices operating in a wireless network, the node comprising circuitry configured to:determine a channel quality parameter for the node indicative of a channel quality between the node and the plurality of wireless devices;
receive a first message from a first neighbor node in the CoMP set, the first message including a channel quality parameter for a third node in the CoMP set indicative of a channel quality between the third node and the plurality of wireless devices, wherein the third node comprises one of the first neighbor node and a member node of the CoMP set other than the node and the first neighbor node; and
send a second message to the first neighbor node in the CoMP set, the second message identifying the coordination node elected by the node based on the channel quality parameters for the node and the third node.
