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.

First claim

What is claimed is:

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.
