Abstract
Embodiments of the present invention provide methods for transmitting and receiving a control channel, a base station, and a user equipment, which relate to the communication field, and can solve a transmission problem of available changing transmission resources caused by introduction of an E-PDCCH. A method includes determining, by a terminal device, a resource set and resource elements (REs) of predetermined overheads in the resource set. The REs of the predetermined overheads include an RE of at least one of a paging channel and a synchronization channel, with at least one of following REs: an RE of a channel state information-reference signal (CSI-RS), an RE of a cell-specific reference signal (CRS), an RE of a demodulation reference signal (DMRS), or a muted RE. The terminal device receives from a base station, a control channel on an RE subset comprised in the resource set, wherein the RE subset comprises a part of the REs in the resource set and do not contain the REs of the predetermined overheads.
