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.

Claim
1. A method for detecting a common control channel, comprising:
determining a candidate resource set within virtual downlink resources of a current cell, wherein the candidate resource set comprises at least one candidate resource carrying a common control channel of the current cell; and performing a detection on at least one candidate resource in the candidate resource set, so as to acquire the common control channel of the current cell.
2. The method according to claim 1, wherein:
before the determining the candidate resource set within the virtual downlink resources of the current cell, the method further comprises: acquiring frequency domain position information of the current cell, wherein the frequency domain position information comprises a central frequency point position of the current cell and/or a frequency domain central resource position of the current cell; and determining the virtual downlink resources according to the frequency domain position information.
3. The method according to claim 1, further comprising:
determining an actual downlink resource bandwidth of the current cell according to position information of a common control channel detected resource, wherein the common control channel detected resource is a candidate resource detecting the common control channel of the current cell; or determining the actual downlink resource bandwidth of the current cell according to downlink resource bandwidth indication information carried by the common control channel of the current cell.
4. The method according to claim 3, wherein the determining the actual downlink resource bandwidth of the current cell, comprises:
determining, according to a common control channel detected resource of a cell to be determined, a first downlink resource bandwidth; and if a positional relationship between the common control channel detected resource of the cell to be determined and the current cell conforms to a positional relationship indicated by resource position indication information carried by a common control channel of the cell to be determined, determining that the first downlink resource bandwidth is the actual downlink resource bandwidth of the current cell, wherein the resource position indication information carried by the common control channel of the cell to be determined indicates a positional relationship between the common control channel detected resource of the cell to be determined and the cell to be determined.
5. A user equipment, comprising:
a determination unit, configured to determine a candidate resource set within virtual downlink resources of a current cell, wherein the candidate resource set comprises at least one candidate resource carrying a common control channel of the current cell; and a detection unit, configured to perform a detection on at least one candidate resource in the candidate resource set, so as to acquire the common control channel of the current cell.
6. The user equipment according to claim 5, further comprising:
a first acquisition unit, configured to acquire frequency domain position information of the current cell, wherein the frequency domain position information comprises a central frequency point position of the current cell and/or a frequency domain central resource position of the current cell; wherein the determination unit is further configured to determine the virtual downlink resources according to the frequency domain position information.
7. The user equipment according to claim 5, wherein:
the determination unit is further configured to determine, according to position information of a common control channel detected resource, an actual downlink resource bandwidth of the current cell, wherein the common control channel detected resource is a candidate resource detecting the common control channel of the current cell; or the determination unit is further configured to determine, according to downlink resource bandwidth indication information carried by the common control channel of the current cell, the actual downlink resource bandwidth of the current cell.
8. The user equipment according to claim 7, wherein:
the determination unit is specifically configured to determine, according to an common control channel detected resource of a cell to be determined, a first downlink resource bandwidth; and if a positional relationship between the common control channel detected resource of the cell to be determined and the current cell conforms to a positional relationship indicated by resource position indication information carried by a common control channel of the cell to be determined, the determination unit is further specifically configured to determine that the first downlink resource bandwidth is the actual downlink resource bandwidth of the current cell, wherein the resource position indication information carried by the common control channel of the cell to be determined indicates a positional relationship between the common control channel detected resource of the cell to be determined and the cell to be determined.
