Abstract
The present disclosure relates to methods for obtaining a quantity of blind detection times, and apparatus. One example method comprises receiving, by a terminal device, second information from a network device, where the second information comprises subcarrier spacing information, and determining, by the terminal device based on the subcarrier spacing information, a maximum quantity of blind detection times for the terminal device in a search space.
Claims12
A method, wherein the method comprises:
- receiving, by a terminal device, subcarrier spacing information from a network device;
- sending, by the terminal device to the network device, information related to a maximum quantity of blind detection times supported by the terminal device;
- determining, by the terminal device based on information about a quantity of aggregated carriers and the subcarrier spacing information, a maximum quantity of blind detection times for the terminal device on each of a plurality of carriers;
- and
- monitoring, by the terminal device based on the maximum quantity of blind detection times for the terminal device on each of the plurality of carriers, physical downlink control channels (PDCCHs) on the plurality of carriers, wherein a total number of the blind detection times on the plurality of carriers does not exceed the maximum quantity of blind detection times supported by the terminal device, a quantity of blind detection times for the terminal device on each of the plurality of carriers does not exceed the maximum quantity of blind detection times for the terminal device on each of the plurality of carriers, and does not exceed the maximum quantity of blind detection times supported by the terminal device divided by the number of the plurality of carrier.
