Abstract:
A method in a communication node for mapping symbols of an Enhanced Physical Downlink Control Channel, EPDCCH, message is provided. The EPDCCH comprises one or more aggregation levels. For each aggregation level, an EPDCCH message is constituted by a set of Control Channel Elements, eCCEs. Each eCCE is mapped to a set of multiple enhanced Resource Element Groups, eREGs, wherein each eREG is a group of Resource Elements, REs, in a Physical Resource Block, PRB, pair. The communication node maps the symbols of the EPDCCH message to the set of REs that constitutes the multiple eREGs that the set of eCCEs correspond to. The order in which the EPDCCH symbols are mapped to the set of REs is dependent on the aggregation level.
