Detecting method, transmitting method and apparatus for common control channel

An apparatus, comprising:

• a storage medium including executable instructions;
• and
• a processor;
• wherein the executable instructions, when executed by the processor, cause the apparatus to:
• select a first resource from a first candidate resource set within downlink resources of a cell;
• transmit a first common control channel on the first resource, wherein the first common control channel carries a common search space indication information, the common search space indication information and position information of the first resource are used to indicate an actual resource of a common search space in a second candidate resource set of the cell, the second candidate resource set is a subset of a common search space candidate resource set, the common search space candidate resource set comprises at least two subsets, and each subset of the at least two subsets corresponds to a candidate resource of the first candidate resource set;
• and
• transmit a second common control channel in the common search space.

A non-transitory computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to carry out the steps of:

• selecting a first resource from a first candidate resource set within downlink resources of a cell;
• transmitting a first common control channel on the first resource, wherein the first common control channel carries a common search space indication information, the common search space indication information and position information of the first resource are used to indicate an actual resource of a common search space in a second candidate resource set of the cell, the second candidate resource set is a subset of a common search space candidate resource set, the common search space candidate resource set comprises at least two subsets, and each subset of the at least two subsets corresponds to a candidate resource of the first candidate resource set;
• and
• transmitting a second common control channel in the common search space.
