Claim:
1. A method for Enhanced-Physical Downlink Control Channel, E-PDCCH, transmission, comprising: determining time-frequency resources occupied for E-PDCCH transmission respectively in each sub-frame according to configuration information at a network side; and transmitting E-PDCCHs to a terminal side over the corresponding time-frequency resources respectively in each sub-frame according to a result of the determination; wherein determining the time-frequency resources occupied for E-PDCCH transmission respectively in each sub-frame according to the configuration information at the network side comprises at least one of: determining the number of Enhanced-Resource Element Groups, E-REGs, included in a resource granularity at a single aggregation level respectively in each sub-frame under a preset rule according to the configuration information preset at the network side; and determining a set of aggregation levels and a lowest aggregation level corresponding to each sub-frame respectively under a preset rule according to the configuration information preset at the network side.
