Claim:
1. A method of transmitting information, the method comprising: selecting, by a network side, candidate Enhanced-Physical Downlink Control Channels (E-PDCCHs) for carrying Downlink Control Information (DCI) from a set of candidate E-PDCCHs, wherein the set of candidate E-PDCCHs includes E-PDCCHs occupying a plurality of time-frequency resources consecutive in frequency domain and E-PDCCHs occupying a plurality of time-frequency resources inconsecutive in frequency domain; wherein selecting, by the network side, the candidate E-PDCCHs for carrying the DCI comprises: selecting, by the network side, the candidate E-PDCCHs for carrying the DCI from the set of candidate E-PDCCHs according to at least one aggregation level at which the DCI is to be transmitted, wherein each aggregation level corresponds to a respective number of time-frequency resources occupied by a respective candidate E-PDCCH, and wherein each time-frequency resource is an Enhanced-Control Channel Element (E-CCE) comprising Resource Elements (REs); wherein the size of time-frequency resources occupied at each aggregation level are configured flexibly; wherein before the network side transmits the DCI, the method further comprises: determining, by the network side, the size of time-frequency resources occupied at each aggregation level according to a resource configuration or a carrier configuration or higher-layer instruction information; transmitting, by the network side, the DCI over the selected candidate E-PDCCHs.
