Abstract
The present invention relates to a method, apparatuses, a system, and a computer program product for selecting at least one cooperative node from multiple cooperative nodes (21 to 23) for receiving a signal from a source node (10), wherein at least two stages of a backoff process are provided, in which the candidate cooperative nodes (21 to 23) determine respective backoff numbers according to their channel conditions to the source node (10), wherein the second stage is performed if the first stage was not successful or if a second cooperative node shall be selected.
Claims17
An apparatus for selecting a cooperative node to which a signal is to be transmitted from a source node, said apparatus (21-23) being adapted to determine in a first stage of a backoff process a first backoff number based on a channel condition to said source node (10), and to determine in a subsequent second stage of said backoff process at least a second backoff number based on a subsequent channel condition to said source node (10) and based on a reaction of at least one of said source node (10) and other candidate cooperative nodes in said first stage of said backoff process.
An apparatus for selecting at least one cooperative node to which a signal is to be transmitted from said apparatus (10), said apparatus (10) being adapted to initiate a first stage of a backoff process in which candidate cooperative nodes (21 to 23) determine backoff numbers according to their channel conditions to said apparatus (10), and to initiate a subsequent second stage of said backoff process if said first stage was not successful or if a second cooperative node shall be selected.

A method of selecting at least one cooperative node from multiple cooperative nodes (21 to 23) for receiving a signal from a source node (10), said method comprising at least two stages of a backoff process in which said candidate cooperative nodes (21 to 23) determine respective backoff numbers according to their channel conditions to said source node (10), wherein said second stage is performed if said first stage was not successful or if a second cooperative node shall be selected.
