Abstract

A scheduling switching method includes receiving, by a terminal, a switching indication from a network device, where the switching indication indicates the terminal to switch from a first scheduling mode to a second scheduling mode. The method further includes determining an application time of the second scheduling mode such that the terminal schedules a data channel or triggers a reference signal using the second scheduling mode when the application time arrives.

Claims (31)

1. A scheduling switching method implemented by a terminal, wherein the scheduling switching method comprises:

receiving, from a network device, a switching indication indicating the terminal to switch from a first scheduling mode to a second scheduling mode, wherein the first scheduling mode is different from the second scheduling mode; and

determining an application time of the second scheduling mode,

wherein the application time is when the terminal can schedule a first data channel or trigger a first reference signal using the second scheduling mode,

wherein the switching indication is received via a first physical downlink control channel (PDCCH), wherein the first PDCCH is associated with an N th slot, wherein N is an integer, and wherein the application time is an (N+M) th slot,

wherein M is based on an applicable minimum value of a slot offset when the terminal receives the switching indication, wherein the slot offset is between a slot associated with a second PDCCH for scheduling a second data channel and a slot associated with the second data channel, wherein M is a maximum value of a second value and the applicable minimum value, and wherein the second value is related to a subcarrier spacing configured for the terminal.

2. The scheduling switching method of claim 1 , wherein the second value is 1.

3. The scheduling switching method of claim 1 , wherein the first scheduling mode or the second scheduling mode is indicated in at least one of an applicable minimum value of K0, an applicable minimum value of K2, or an applicable minimum value of an aperiodic channel state information reference signal (CSI-RS) triggering offset.

4. The scheduling switching method of claim 1 , wherein the switching indication comprises an index indicating the second scheduling mode.

5. The scheduling switching method of claim 4 , wherein the index corresponds to a minimum value of K0 or a minimum value of K2.

6. The scheduling switching method of claim 1 , wherein the PDCCH is for further scheduling a second reference signal, wherein the second data channel is a downlink data channel or an uplink data channel, and wherein the second reference signal is a channel state information reference signal (CSI-RS).

7. A communications apparatus comprising:

a processor; and

a memory coupled to the processor and configured to store programming instructions that, when executed by the processor, cause the communications apparatus to:

receive, from a network device, a switching indication indicating the communications apparatus to switch from a first scheduling mode to a second scheduling mode, wherein the first scheduling mode is different from the second scheduling mode; and

determine an application time of the second scheduling mode,

wherein the application time is when the communications apparatus can schedule a first data channel or trigger a first reference signal using the second scheduling mode,

wherein the switching indication is received via a first physical downlink control channel (PDCCH), wherein the first PDCCH is associated with an N th slot, wherein N is an integer, wherein the application time is an (N+M) th slot,

wherein M is based on an applicable minimum value of a slot offset when the communications apparatus receives the switching indication, wherein the slot offset is between a slot associated with a second PDCCH for scheduling a second data channel and a slot associated with the second data channel, wherein M is a maximum value of a second value and the applicable minimum value, and wherein the second value is related to a subcarrier spacing configured for the communications apparatus.

8. The communications apparatus of claim 7 , wherein the second value is 1.

9. The communications apparatus of claim 7 , wherein the first scheduling mode or the second scheduling mode is indicated in at least one of an applicable minimum value of K0, an applicable minimum value of K2, or an applicable minimum value of an aperiodic channel state information reference signal (CSI-RS) triggering offset.

10. The communications apparatus of claim 7 , wherein the switching indication comprises an index indicating the second scheduling mode.

11. The communications apparatus of claim 10 , wherein the index corresponds to a minimum value of K0 or a minimum value of K2.

12. The communications apparatus of claim 7 , wherein the PDCCH for further scheduling a second reference signal, wherein the second data channel is a downlink data channel or an uplink data channel, and wherein the second reference signal is a channel state information reference signal (CSI-RS).

13. A computer program product comprising computer-executable instructions that are stored on a non-transitory computer readable medium and that, when executed by a processor of a communications apparatus, cause the communications apparatus to:

receive, from a network device, a switching indication indicating the communications apparatus to switch from a first scheduling mode to a second scheduling mode, wherein the first scheduling mode is different from the second scheduling mode; and

determine an application time of the second scheduling mode,

wherein the application time is when the communications apparatus can schedule a first data channel or trigger a first reference signal using the second scheduling mode,

wherein the switching indication is received via a first physical downlink control channel (PDCCH), wherein the first PDCCH is associated with an N th slot, wherein N is an integer, wherein the application time is an (N+M) th slot,

wherein M is based on an applicable minimum value of a slot offset when the communications apparatus receives the switching indication, wherein the slot offset is between a slot associated with a second PDCCH for scheduling a second data channel and a slot associated with the second data channel, wherein M is a maximum value of a second value and the applicable minimum value, and wherein the second value is related to a subcarrier spacing configured for the communications apparatus.

14. The computer program product of claim 13 , wherein the second value is 1.
