Control information sending/receiving method and device

A control information receiving apparatus comprising:

• a storage medium including executable instructions;
• and
• a processor;
• wherein the executable instructions, when executed by the processor, cause the apparatus to:
• receive broadcast information carried in a broadcast channel, wherein the broadcast information includes indication information indicating a time-domain resource set of control channels;
• determine a time-domain location of a control channel from the time-domain resource set based on a time-domain location of the broadcast channel, wherein the time-domain location of the broadcast channel is one of at least two predefined time-domain locations in at least one timeslot;
• and
• perform control channel detection in the time-domain location of the control channel.

A non-transitory computer-readable storage medium comprising executable instructions, wherein the executable instructions, when executed by a computer, cause the computer to:

• receive broadcast information carried in a broadcast channel, wherein the broadcast information includes indication information indicating a time-domain resource set of control channels;
• determine a time-domain location of a control channel from the time-domain resource set based on a time-domain location of the broadcast channel, wherein the time-domain location of the broadcast channel is one of at least two predefined time-domain locations in at least one timeslot;
• and
• perform control channel detection in the time-domain location of the control channel.
