METHODS AND APPARATUSES FOR INTERFERENCE COORDINATION IN A TELECOMMUNICATIONS SYSTEM

摘要

The embodiments of the present invention relate to methods and apparatuses (600, 700) for coordinating interference in a telecommunications LTE based system. According to exemplary embodiments, an apparatus acting as a macro radio base station (eNB) (600) is configured to decide on what radio resources to schedule to its UEs and further decide on what resources to leave unutilized. Information on the decided resources is further transmitted in an interference coordinate signalling message, to at least one relay node (RN) (700) via at least one layer (1) control channel. The interference coordination signalling message will assist the RN (700) to make its own scheduling decision based on the information in the signalling message.
