Abstract

A method for optimizing a blind detection capability is performed by a terminal, and includes: determining blind detection capability information, wherein the blind detection capability information includes a maximum number of physical downlink control channel (PDCCH) candidates monitored in n time slots under a first subcarrier spacing, and a maximum number of non-overlapped control channel elements (CCEs) in the n time slots under the first subcarrier spacing, where n is an integer greater than 1.

Claims (27)

1 . A method for optimizing a blind detection capability, performed by a terminal, the method comprising:

determining blind detection capability information, wherein the blind detection capability information comprises a maximum number of physical downlink control channel (PDCCH) candidates monitored in n time slots under a first subcarrier spacing, and a maximum number of non-overlapped control channel elements (CCEs) in the n time slots under the first subcarrier spacing, where n is an integer greater than 1;

receiving resource information of a PDCCH sent by a base station;

determining a target time slot where the PDCCH is located in the n time slots based on the resource information; and

performing a blind detection on downlink control information in the PDCCH in the target time slot based on the blind detection capability information;

wherein the resource information comprises a control resource set and a search space.

2 . The method according to claim 1 , wherein the blind detection capability information further comprises a maximum number of PDCCH candidates monitored in each time slot under a second subcarrier spacing and a maximum number of non-overlapped CCEs in each time slot under the second subcarrier spacing, wherein the second subcarrier spacing is less than the first subcarrier spacing.

3 . The method according to claim 2 , wherein the second subcarrier spacing is one of 15 KHz, 30 KHz, 60 KHz, or 120 KHz.

4 . An electronic device, comprising:

a processor; and

a memory configured to store instructions executable by the processor;

wherein the processor is configured to:

determine blind detection capability information, wherein the blind detection capability information comprises a maximum number of physical downlink control channel (PDCCH) candidates monitored in n time slots under a first subcarrier spacing, and a maximum number of non-overlapped control channel elements (CCEs) in the n time slots under the first subcarrier spacing, where n is an integer greater than 1;

receive resource information of a PDCCH sent by a base station;

determine a target time slot where the PDCCH is located in the n time slots based on the resource information; and

perform a blind detection on downlink control information in the PDCCH in the target time slot based on the blind detection capability information;

wherein the resource information comprises a control resource set and a search space.

5 . The electronic device according to claim 4 , wherein the blind detection capability information further comprises a maximum number of PDCCH candidates monitored in each time slot under a second subcarrier spacing and a maximum number of non-overlapped CCEs in each time slot under the second subcarrier spacing, wherein the second subcarrier spacing is less than the first subcarrier spacing.

6 . The electronic device according to claim 5 , wherein the second subcarrier spacing is one of 15 KHz, 30 KHz, 60 KHz, or 120 KHz.

7 . A non-transitory computer readable storage medium having stored thereon a computer program that, when executed by a processor, cause the processor to perform a method for optimizing a blind detection capability, the method comprising:

determining blind detection capability information, wherein the blind detection capability information comprises a maximum number of physical downlink control channel (PDCCH) candidates monitored in n time slots under a first subcarrier spacing, and a maximum number of non-overlapped control channel elements (CCEs) in the n time slots under the first subcarrier spacing, where n is an integer greater than 1;

receiving resource information of a PDCCH sent by a base station;

determining a target time slot where the PDCCH is located in the n time slots based on the resource information; and

performing a blind detection on downlink control information in the PDCCH in the target time slot based on the blind detection capability information;

wherein the resource information comprises a control resource set and a search space.

8 . The non-transitory computer readable storage medium according to claim 7 , wherein the blind detection capability information further comprises a maximum number of PDCCH candidates monitored in each time slot under a second subcarrier spacing and a maximum number of non-overlapped CCEs in each time slot under the second subcarrier spacing, wherein the second subcarrier spacing is less than the first subcarrier spacing.

9 . The non-transitory computer readable storage medium according to claim 8 , wherein the second subcarrier spacing is one of 15 KHz, 30 KHz, 60 KHz, or 120 KHz.
