Abstract

Disclosed are channel monitoring and a control method and apparatus thereof. The channel monitoring control method provided in the present application includes determining PDCCH monitoring solution instruction information; and sending the PDCCH monitoring solution instruction information to the terminal for instructing the terminal to adjust the PDCCH monitoring solution.

Claims (54)

1. A method for controlling channel monitoring, comprising:

determining physical downlink control channel (PDCCH) monitoring scheme indication information; and

sending the PDCCH monitoring scheme indication information to one or more terminals for indicating the one or more terminals to adjust a PDCCH monitoring scheme, via adding a new bit field to a downlink control information (DCI) format;

wherein the PDCCH monitoring scheme indication information comprises indication information of a combination of following functions:

function 1: an indication of whether to skip a next or a plurality of subsequent PDCCH monitoring occasions;

function 3: an indication of a cycle of a PDCCH monitoring occasion;

function 4: an indication of a control resource set (CORESET) where a PDCCH monitoring occasion is located;

function 5: an indication of a monitoring pattern of a PDCCH monitoring occasion;

function 6: an indication of a PDCCH monitoring aggregation level and/or a quantity of PDCCH candidates per PDCCH monitoring occasion aggregation level; and

function 7: an indication of monitoring a duration of consecutive slots where a PDCCH search space is located;

wherein the DCI format is DCI format 1_1 or DCI format 1_0 or DCI format 2_6; and the new bit field corresponds to joint coding of the function 1 and the function 3 to the function 7.

2. The method according to claim 1 , wherein the sending the PDCCH monitoring scheme indication information to the one or more terminals comprises:

sending the PDCCH monitoring scheme indication information to the one or more terminals via the DCI format and/or a medium access control control element (MAC CE).

3. The method according to claim 1 , wherein the sending the PDCCH monitoring scheme indication information to the one or more terminals comprises:

sending the PDCCH monitoring scheme indication information to the one or more terminals in an explicit manner or an implicit manner.

4. A channel monitoring method, comprising:

receiving physical downlink control channel (PDCCH) monitoring scheme indication information sent by a network side via a new bit field added to a downlink control information (DCI) format; and

adjusting a PDCCH monitoring scheme according to the PDCCH monitoring scheme indication information;

wherein the PDCCH monitoring scheme indication information comprises indication information of a combination of following functions:

function 1: an indication of whether to skip a next or a plurality of subsequent PDCCH monitoring occasions;

function 3: an indication of a cycle of a PDCCH monitoring occasion;

function 4: an indication of a control resource set (CORESET) where a PDCCH monitoring occasion is located;

function 5: an indication of a monitoring pattern of a PDCCH monitoring occasion;

function 6: an indication of a PDCCH monitoring aggregation level and/or a quantity of PDCCH candidates per PDCCH monitoring occasion aggregation level; and

function 7: an indication of monitoring a duration of consecutive slots where a PDCCH search space is located;

wherein the DCI format is DCI format 1_1 or DCI format 1_0 or DCI format 2_6; and the new bit field corresponds to joint coding of the function 1 and the function 3 to the function 7.

5. The method according to claim 4 , wherein the receiving the PDCCH monitoring scheme indication information sent by the network side comprises:

receiving the PDCCH monitoring scheme indication information via the DCI format and/or a medium access control control element (MAC CE).

6. The method according to claim 4 , wherein the receiving the PDCCH monitoring scheme indication information sent by the network side comprises:

receiving the PDCCH monitoring scheme indication information in an explicit manner or an implicit manner.

7. An apparatus for controlling channel monitoring, comprising:

a memory, configured to store program instructions; and

a processor, configured to call the program instructions stored in the memory, and execute the method of claim 1 .

8. The apparatus according to claim 7 , wherein the processor is configured to:

send the PDCCH monitoring scheme indication information to the one or more terminals via a downlink control information (DCI) format and/or a medium access control control element (MAC CE).

9. The apparatus according to claim 7 , wherein the processor is configured to:

send the PDCCH monitoring scheme indication information to the one or more terminals in an explicit manner or an implicit manner.

10. A channel monitoring apparatus, comprising:

a memory, configured to store program instructions; and

a processor, configured to call the program instructions stored in the memory, and execute according to an obtained program:

receiving physical downlink control channel (PDCCH) monitoring scheme indication information sent by a network side via a new bit field added to a downlink control information (DCI) format; and

adjusting a PDCCH monitoring scheme according to the PDCCH monitoring scheme indication information;

wherein the PDCCH monitoring scheme indication information comprises indication information of a combination of following functions:

function 1: an indication of whether to skip a next or a plurality of subsequent PDCCH monitoring occasions;

function 3: an indication of a cycle of a PDCCH monitoring occasion;

function 4: an indication of a control resource set (CORESET) where a PDCCH monitoring occasion is located;

function 5: an indication of a monitoring pattern of a PDCCH monitoring occasion;

function 6: an indication of a PDCCH monitoring aggregation level and/or a quantity of PDCCH candidates per PDCCH monitoring occasion aggregation level; and

function 7: an indication of monitoring a duration of consecutive slots where a PDCCH search space is located;

wherein the DCI format is DCI format 1_1 or DCI format 1_0 or DCI format 2_6; and the new bit field corresponds to joint coding of the function 1 and the function 3 to the function 7.

11. The apparatus according to claim 10 , wherein the processor is configured to:

receive the PDCCH monitoring scheme indication information via a downlink control information (DCI) format and/or a medium access control control element (MAC CE).

12. The apparatus according to claim 10 , wherein the processor is configured to:

receive the PDCCH monitoring scheme indication information in an explicit manner or an implicit manner.
