Claim Text:
1. A method of decoding downlink control information by a user equipment (UE) in an OFDM/OFDMA system, the method comprising: (a) receiving a control signal from a base station to determine received physical resource blocks (PRBs) that carry the downlink control information; (b) determining a set of candidate enhanced physical downlink control channels (ePDCCHs) within the PRBs, wherein each ePDCCH is associated with a set of enhanced control channel elements (eCCEs) for ePDCCH transmission; (c) collecting a plurality of enhanced resource element groups (eREGs) for each eCCE, wherein each eCCE consists of a number of eREGs based on an eCCE to eREG mapping rule; (d) collecting a plurality of resource elements (REs) for each eREG, wherein each eREG consists of a number of REs based on an eREG to RE mapping rule; and (e) decoding the downlink control information that are mapped to the collected REs.
