wherein the first indication signal further comprises a second parameter, the second parameter being used to determine a search space to which the parameter for PDCCH detection is applicable;

wherein the second parameter comprises a search space index value;

wherein the second parameter being used to determine the search space to which the parameter for PDCCH detection is applicable, comprises:

the parameter for PDCCH detection being corresponding to a search space corresponding to the index value.

2. The method according to claim 1 , wherein the parameter for PDCCH detection is used to indicate that the terminal device detects a specific part of search spaces among all search spaces.

3. The method according to claim 1 , wherein the first indication signal comprises the parameter for PDCCH detection, and the parameter for PDCCH detection corresponds to a first type search space of the terminal device.

4. The method according to claim 1 , wherein a type of the search space is configured by the network side.

5. The method according to claim 1 , further comprising:

receiving a second indication signal sent from the network side and obtaining carrier information and/or BandWidth Part (BWP) information of the PDCCH that needs to be detected.
