Abstract
The present disclosure provides a clear channel assessment detection method and apparatus. The method includes: acquiring a clear channel assessment (CCA) detection pattern or a Muting pattern; and performing a CCA detection to an unlicensed carrier channel on resources corresponding to one of the CCA detection pattern or the Muting pattern.
Claims17
A clear channel assessment detection method, comprising:
- acquiring a clear channel assessment (CCA) detection pattern or a Muting pattern;
- and
- performing a CCA detection to an unlicensed carrier channel on resources corresponding to one of the CCA detection pattern or the Muting pattern;
- wherein, a same CCA detection pattern or Muting pattern is configured for base stations in a same operator;
- or different CCA detection patterns or different Muting patterns are configured for different operators;
- or different CCA detection patterns or different Muting patterns are configured on different base stations in a same system under a same operator;
- the method further comprises:
- a transmission equipment in the same system under the same operator performing the CCA detection on a whole bandwidth or on resources beyond the configured CCA detection pattern or Muting pattern, which comprises:
- determining that the transmission equipment is capable of performing multiplexing with another transmission equipment that is in the same system under the same operator and occupies a channel already or the transmission equipment determines that the unlicensed carrier channel is available under a condition that energy detected on the whole bandwidth or on resources corresponding to a complementary set of the corresponding CCA detection pattern or Muting pattern is greater than a first threshold value and less than a second threshold value;
- determining that the unlicensed carrier channel is in an idle state under a condition that the energy detected on the whole bandwidth or on the resources corresponding to the complementary set of the corresponding CCA detection pattern or Muting pattern is less than the first threshold value;
- determining one of the followings under a condition that the energy detected on the resources corresponding to the complementary set of the corresponding CCA detection pattern or Muting pattern is greater than the second threshold value:
- the unlicensed carrier is in an unavailable state, or the unlicensed carrier is being used by other transmission equipments or an equipment in the inter-operator.

A clear channel assessment (CCA) detection apparatus, comprising a processor and a storage device, wherein the storage device stores processor-executable programs, and the programs comprise:
- an acquisition module, configured to acquire a CCA detection pattern or a Muting pattern;
- and
- a detection module, configured to perform a CCA detection to an unlicensed carrier channel on resources corresponding to one of the CCA detection pattern or the Muting pattern;
- wherein, a same CCA detection pattern or Muting pattern is configured for base stations in a same operator;
- or different CCA detection patterns or different Muting patterns are configured for different operators;
- or different CCA detection patterns or different Muting patterns are configured on different base stations in a same system under a same operator;
- the detection module further configured to determine that a transmission equipment is capable of performing multiplexing with another transmission equipment that is in the same system under the same operator and occupies a channel already or a transmission equipment determines that the unlicensed carrier channel is available under a condition that energy detected on a whole bandwidth or on resources corresponding to a complementary set of the corresponding CCA detection pattern or Muting pattern is greater than a first threshold value and less than a second threshold value;
- determine that the unlicensed carrier channel is in an idle state under a condition that the energy detected on the whole bandwidth or on the resources corresponding to the complementary set of the corresponding CCA detection pattern or Muting pattern is less than the first threshold value;
- and determine that one of the followings under a condition that the energy detected on the resources corresponding to the complementary set of the corresponding CCA detection pattern or Muting pattern is greater than the second threshold value:
- the unlicensed carrier is in an unavailable state, or the unlicensed carrier is being used by other transmission equipments or an equipment in the inter-operator.
