Methods for transmitting and receiving control channel, base station, and user equipment

A terminal device, comprising:

• a receiver;
• and
• a processor communicatively connected with the receiver, wherein the processor is configured to:
• determine a resource set and resource elements (REs) of predetermined overheads in the resource set, wherein the REs of the predetermined overheads comprise an RE of at least one of a paging channel and a synchronization channel, and 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, and
• decode 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.

An apparatus comprising:

• a storage medium comprising executable instructions;
• and
• a processor, wherein the executable instructions, when executed by the processor, cause the apparatus to:
• determine a resource set and resource elements (REs) of predetermined overheads in the resource set, wherein the REs of the predetermined overheads comprise an RE of at least one of a paging channel and a synchronization channel, and 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, and
• decode 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.
