Abstract
Provided in the embodiments is a channel access method and apparatus, a user equipment (UE), a base station and a computer storage medium. A priority class in use of an unlicensed carrier is determined, and channel access of the unlicensed carrier is performed according to a clear channel assessment (CCA) parameter matching the determined priority class and used for performing a CCA detection before access to the unlicensed carrier.
Claims25
A channel access method, comprising:
- determining a priority class in use of an unlicensed carrier;
- and
- performing channel access of the unlicensed carrier according to a clear channel assessment (CCA) parameter, wherein the CCA parameter matches the determined priority class and is used for performing a CCA detection before access to the unlicensed carrier.

The method of claim 10, wherein the CCA starting point is determined in one manner of a group consisting of:
- a base station notifies a UE of the CCA starting point through physical layer signaling;
- the base station notifies the UE with the CCA starting position through high-layer signaling;
- and
- the base station and the UE achieve an agreement on the CCA starting point in advance;
- wherein the physical layer signaling comprises:
- UE-specific DCI or common DCI;
- or the high layer signaling is configured to the UE through RRC signaling.
(canceled)
A channel access apparatus, comprising:
- a processor;
- and
- a memory for storing instructions executable by the processor,
- wherein the processor is configured to:
- determine a priority class in use of an unlicensed carrier;
- and
- perform channel access of the unlicensed carrier according to a clear channel assessment (CCA) parameter, wherein the CCA parameter matches the determined priority class and is used for performing a CCA detection before access to the unlicensed carrier.
