Abstract: Embodiments provide a control channel transmission method and apparatus. A control channel is mapped to an eREG. That corresponds to determined eREG information, among a designated number of eREGs in each unit physical resource block. Each eREG among the designated number of the eREGs is formed by a designated number of resource elements. The designated number of the resource elements are selected from corresponding resource elements at an Sth position in each group. S is a positive integer smaller than or equal to N. The control channel can be transmitted on the mapped eREG.
