Abstract
In downlink signal communication to a mobile terminal (200), the mobile terminal (200) is associated with a serving access node (100-1). Signal communication to a further mobile terminal (200; 200′″) may interfere with the signal communication between the serving access node (100-1) and the mobile terminal (200). In order to allow interference mitigation at the mobile terminal (200), the serving access node (100-1) obtains scheduling information pertaining to the signal communication to the further mobile terminal (200; 200′″). The obtained scheduling information is then forwarded to the mobile terminal (200) to be used for interference mitigation.
