Abstract
Embodiments of the present invention provide a detecting method, a transmitting method and an apparatus for a common control channel. The detecting method includes: determining a candidate resource set within virtual downlink resources of a current cell. The candidate resource set can include at least one candidate resource carrying a common control channel of the current cell. A detection is performed on at least one candidate resource in the candidate resource set, so as to acquire the common control channel of the current cell. In the embodiments of the present invention, a selection range of resources for transmitting a common control channel is extended, so that inter-cell interference of the common control channel can be coordinated, and a detection performance of the common control channel can be improved.

determining, by a network device, a first candidate resource set within downlink resources of a cell; selecting, by the network device, a first resource from the first candidate resource set of the cell; and transmitting, by the network device, a first common control channel on the first resource, wherein the common control channel carries a common search space indication information, the common search space indication information is used to indicate an actual resource of a common search space in a second candidate resource set of the cell; and transmitting, by the network device, a second common control channel in the common search space.
2. The method according to claim 1, wherein position information of the at least one first resource indicates the second candidate resource set.
3. The method according to claim 2, wherein 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, each subset of the at least two subsets corresponds to a candidate resource of the first candidate resource set.
4. The method according to claim 1, wherein the actual resource indicated by the common search space indication information is all or a part of a candidate resource of the first candidate resource set corresponding to the candidate resource set.
5. The method according to claim 1, wherein the downlink resources are candidate resources for detecting the first common control channel of the cell, and a bandwidth of the downlink resources equal to a predefined.
6. The method according to claim 1, wherein the first common control channel carries system radio frame number.
7. The method according to claim 6, wherein the first common control channel is a physical broadcasting channel.
8. The method according to claim 1, wherein position information of the at least one first resource is also used to indicate the actual resource of the common search space.
9. 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: determine a first candidate resource set within downlink resources of a cell; select a first resource from the first candidate resource set of the cell; and transmit a first common control channel on the first resource, wherein the common control channel carries a common search space indication information, the common search space indication information is used to indicate an actual resource of a common search space in a second candidate resource set of the cell; and transmit a second common control channel in the common search space.
10. The apparatus according to claim 9, wherein position information of the at least one first resource indicates the second candidate resource set.
11. The apparatus according to claim 10, wherein 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, each subset of the at least two subsets corresponds to a candidate resource of the first candidate resource set.
12. The apparatus according to claim 9, wherein the actual resource indicated by the common search space indication information is all or a part of a candidate resource of the first candidate resource set corresponding to the candidate resource set.
13. The apparatus according to claim 9, wherein the downlink resources are candidate resources for detecting the first common control channel of the cell, and a bandwidth of the downlink resources equal to a predefined.
14. The apparatus according to claim 9, wherein the first common control channel carries system radio frame number.
15. The apparatus according to claim 14, wherein the first common control channel is a physical broadcasting channel.
16. The apparatus according to claim 9, wherein position information of the at least one first resource is also used to indicate the actual resource of the common search space.
17. A non-transitory computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to carry out the steps of:
determining a first candidate resource set within downlink resources of a cell; selecting a first resource from the first candidate resource set of the cell; and transmitting a first common control channel on the first resource, wherein the common control channel carries a common search space indication information, the common search space indication information is used to indicate an actual resource of a common search space in a second candidate resource set of the cell; and transmitting a second common control channel in the common search space.
18. The non-transitory computer-readable storage medium according to claim 17, wherein position information of the at least one first resource indicates the second candidate resource set.
19. The non-transitory computer-readable storage medium according to claim 18, wherein 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, each subset of the at least two subsets corresponds to a candidate resource of the first candidate resource set.
20. The non-transitory computer-readable storage medium according to claim 17, wherein the actual resource indicated by the common search space indication information is all or a part of a candidate resource of the first candidate resource set corresponding to the candidate resource set.
21. The non-transitory computer-readable storage medium according to claim 17, wherein the downlink resources are candidate resources for detecting the first common control channel of the cell, and a bandwidth of the downlink resources equal to a predefined.
