Abstract
Methods, systems, and apparatus for downlink control information (DCI) detection are provided. In one aspect, a DCI detection method includes: receiving a configuration parameter that is used to configure at least one or more groups of candidate resources, each of the one or more groups of candidate resources carrying one piece of DCI, and in response to determining that one corresponding piece of DCI is blindly detected from one of the one or more groups of candidate resources, stopping the blind detection on the one of the one or more groups of candidate resources.
Claims14
A downlink control information (DCI) detection method, comprising:
- receiving a configuration parameter, wherein the configuration parameter is used to configure one or more groups of candidate resources, and wherein each group of candidate resources in the of the one or more groups of candidate resources carries only one piece of DCI;
- and
- for each group of candidate resources in the one or more groups of candidate resources:
- determining that the one piece of DCI is detected after blind detection on a subset of the candidate resources in the group of candidate resources;
- and
- in response to determining that the one piece of DCI is detected, stopping blind detection on remaining candidate resources in the group of candidate resources.
A communications apparatus, comprising:
- at least one processor;
- and
- one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:
- cause a transceiver to receive a configuration parameter, wherein the configuration parameter is used to configure one or more groups of candidate resources, and wherein each group of candidate resources in the of the one or more groups of candidate resources carries only one piece of DCI;
- and
- for each group of candidate resources in the one or more groups of candidate resources:
- determining that the one piece of DCI is detected after blind detection on a subset of the candidate resources in the group of candidate resources;
- and
- in response to determining that the one piece of DCI is detected, stopping blind detection on remaining candidate resources in the group of candidate resources.
A communications apparatus, comprising:
- at least one processor;
- and
- one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:
- generate a configuration parameter, wherein the configuration parameter is used to configure one or more groups of candidate resources, wherein each group of candidate resources in the of the one or more groups of candidate resources carries only one piece of DCI, and wherein the configuration parameter includes indication information that indicates that each group of candidate resources includes only one piece of indication information, and
- cause a transceiver to send the configuration parameter to a terminal device.
