A control channel transmission method, comprising: determining at least one unit physical resource block for transmitting a control channel, characterized in that each unit physical resource block includes 12 sub-carriers in a frequency domain and 14 OFDM symbols in a time domain, and the total 168 resource elements comprises 24 resource elements carrying DMRS and the rest 144 resource elements are divided into 16 eREGs, and each eREG is formed by 9 resource elements; wherein the method further comprises: determining, according to an aggregation level of the control channel and enhanced resource element groups eREGs comprised in each enhanced control channel element eCCE, eREG information of the control channel to be mapped to each unit physical resource block; mapping, according to the eREG information, the control channel to an eREG, which corresponds to the eREG information, among 16 eREGs in each unit physical resource block, wherein the eREG information includes a number of the eREGs in each unit physical resource block and an eREG identifier in each unit physical resource block; the rest 144 resource elements in the each unit physical resource block are numbered cyclically from a first number of 16 consecutive numbers to a last number of 16 consecutive numbers in an increasing order of first frequency, then time; and all resource elements numbered by S constitutes eREG number S; and transmitting the control channel on the mapped eREG. determining at least one unit physical resource block for transmitting a control channel, characterized in that each unit physical resource block includes 12 sub-carriers in a frequency domain and 14 OFDM symbols in a time domain, and the total 168 resource elements comprises 24 resource elements carrying DMRS and the rest 144 resource elements are divided into 16 eREGs, and each eREG is formed by 9 resource elements; wherein the method further comprises: determining, according to an aggregation level of the control channel and enhanced resource element groups eREGs comprised in each enhanced control channel element eCCE, eREG information of the control channel to be mapped to each unit physical resource block; mapping, according to the eREG information, the control channel to an eREG, which corresponds to the eREG information, among 16 eREGs in each unit physical resource block, wherein the eREG information includes a number of the eREGs in each unit physical resource block and an eREG identifier in each unit physical resource block; the rest 144 resource elements in the each unit physical resource block are numbered cyclically from a first number of 16 consecutive numbers to a last number of 16 consecutive numbers in an increasing order of first frequency, then time; and all resource elements numbered by S constitutes eREG number S; and transmitting the control channel on the mapped eREG. determining, according to an aggregation level of the control channel and enhanced resource element groups eREGs comprised in each enhanced control channel element eCCE, eREG information of the control channel to be mapped to each unit physical resource block; mapping, according to the eREG information, the control channel to an eREG, which corresponds to the eREG information, among 16 eREGs in each unit physical resource block, wherein the eREG information includes a number of the eREGs in each unit physical resource block and an eREG identifier in each unit physical resource block; the rest 144 resource elements in the each unit physical resource block are numbered cyclically from a first number of 16 consecutive numbers to a last number of 16 consecutive numbers in an increasing order of first frequency, then time; and all resource elements numbered by S constitutes eREG number S; and transmitting the control channel on the mapped eREG.
