Abstract

Claims (30)

1. A channel monitoring method, comprising:

receiving, by a terminal device, first indication information, wherein the first indication information is used for determining at least one of following: at least one Physical Downlink Control Channel (PDCCH) search space of skipping PDCCH monitoring for the terminal device and a duration of skipping PDCCH monitoring for the terminal device,

wherein the first indication information comprises at least one PDCCH search space Identity (ID) and a first bitmap, and the first bitmap represents whether the terminal device skips the PDCCH monitoring in at least one PDCCH search space marked by the at least one PDCCH search space ID.

2. The method of claim 1 , further comprising:

skipping, by the terminal device, PDCCH monitoring based on the first indication information.

3. The method of claim 2 , wherein the skipping, by the terminal device, the PDCCH monitoring based on the first indication information comprises:

skipping, by the terminal device, the PDCCH monitoring in the at least one PDCCH search space and the duration of skipping PDCCH monitoring determined based on the first indication information.

4. The method of claim 1 , wherein in a case where bit information of a first bit in the first bitmap is a first value, the first bitmap represents that the terminal device skips the PDCCH monitoring in a PDCCH search space corresponding to the first bit; and in a case where the bit information of the first bit in the first bitmap is a second value, the first bitmap represents that the terminal device performs the PDCCH monitoring in the PDCCH search space corresponding to the first bit;

or, in a case where the bit information of the first bit in the first bitmap is the first value, the first bitmap represents that the terminal device performs the PDCCH monitoring in the PDCCH search space corresponding to the first bit; and in a case where the bit information in the first bitmap is the second value, the first bitmap represents that the terminal device skips the PDCCH monitoring in the PDCCH search space corresponding to the first bit.

5. The method of claim 1 , wherein each of the at least one PDCCH search space corresponds to one respective duration of skipping PDCCH monitoring;

or, all of the at least one PDCCH search space correspond to one duration of skipping PDCCH monitoring.

6. The method of claim 1 , wherein the CORESET associated with each of the at least one PDCCH search space corresponds to one respective duration of skipping PDCCH monitoring;

or, all CORESETs associated with all of the at least one PDCCH search space correspond to one duration of skipping PDCCH monitoring.

7. The method of claim 1 , wherein the first indication information is carried in a Medium Access Control (MAC) Control Element (CE) or Downlink Control Information (DCI).

8. A channel monitoring method, comprising:

sending, by a network device, first indication information, wherein the first indication information is used for determining at least one of following: at least one PDCCH search space of skipping PDCCH monitoring for a terminal device and a duration of skipping PDCCH monitoring for the terminal device,

wherein the first indication information comprises at least one PDCCH search space Identity (ID) and a first bitmap, and the first bitmap represents whether the terminal device skips the PDCCH monitoring in at least one PDCCH search space marked by the at least one PDCCH search space ID.

9. The method of claim 8 , wherein each of the at least one PDCCH search space corresponds to one respective duration of skipping PDCCH monitoring;

or, all of the at least one PDCCH search space correspond to one duration of skipping PDCCH monitoring.

10. The method of claim 8 , wherein the first indication information is carried in a MAC CE or DCI.

11. A terminal device, comprising a processor and a memory configured to store instructions that can be executed by the processor, wherein the processor is configured to execute the instructions to perform at least one operation comprising:

receiving first indication information, wherein the first indication information is used for determining at least one of following: at least one PDCCH search space of skipping PDCCH monitoring for the terminal device and a duration of skipping PDCCH monitoring for the terminal device,

wherein the first indication information comprises at least one PDCCH search space Identity (ID) and a first bitmap, and the first bitmap represents whether the terminal device skips the PDCCH monitoring in at least one PDCCH search space marked by the at least one PDCCH search space ID.

12. The terminal device of claim 11 , wherein the at least one operation further comprises:

skipping PDCCH monitoring based on the first indication information.

13. The terminal device of claim 12 , wherein the operation of skipping, by the terminal device, the PDCCH monitoring based on the first indication information comprises:

skipping the PDCCH monitoring in the at least one PDCCH search space and the duration of skipping PDCCH monitoring determined based on the first indication information.

14. The terminal device of claim 11 , wherein each of the at least one PDCCH search space corresponds to one respective duration of skipping PDCCH monitoring PDCCH skipping duration;

or, all of the at least one PDCCH search space correspond to one duration of skipping PDCCH monitoring.

15. The terminal device of claim 11 , wherein the first indication information is carried in a MAC CE or DCI.
