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.

31. A method in a communication node for mapping symbols of an Enhanced Physical Downlink Control Channel (EPDCCH) message, which EPDCCH comprises one or more aggregation levels, wherein for each aggregation level an EPDCCH message is constituted by a set of Control Channel Elements (eCCEs), where 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 method comprising:
mapping the symbols of the EPDCCH message to the set of REs that constitutes the multiple eREGs that the set of eCCEs correspond to, wherein the order in which the EPDCCH symbols are mapped to the set of REs is dependent on the aggregation level. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)

46. A communication node for mapping symbols of an Enhanced Physical Downlink Control Channel (EPDCCH) message, which EPDCCH comprises one or more aggregation levels, wherein for each aggregation level an EPDCCH message is constituted by a set of Control Channel Elements (eCCEs), where 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 comprising:
a channel coding circuit configured to map the symbols of the EPDCCH message to the set of REs that constitutes the multiple eREGs that the set of eCCEs correspond to, wherein the order in which the EPDCCH symbols are mapped to the set of REs is dependent on the aggregation level. - View Dependent Claims (47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60)
