Abstract

A resource indication method and a communications device are provided. The resource indication method includes: detecting a wake-up signal; and determining configuration information of a target resource based on the wake-up signal, where the target resource includes at least one of a measurement resource and a paging resource.

First claim

The invention claimed is:

1. A resource indication method, comprising:
detecting, by a terminal, a wake-up signal; and
determining, by the terminal, a resource indicated by a first measurement resource configuration as a target resource based on the wake-up signal,
wherein the first measurement resource configuration comprises one of a plurality of measurement resource configurations notified to the terminal by using a Radio Resource Control (RRC) message, and is indicated by an indication field included in the wake-up signal, and
wherein the target resource comprises a measurement resource, and the measurement resource comprises a measurement resource of a Channel State Information Reference Signal (CSI-RS) for performing a CSI-RS measurement.

2. The method according to claim 1 , further comprising:
when the wake-up signal indicates wake-up, determining that the target resource exists in resources configured by the plurality of measurement resource configurations; or
when the wake-up signal does not indicate wake-up, determining that the target resource does not exist in the resources configured by the plurality of measurement resource configurations.

3. The method according to claim 1 , wherein determining the resource indicated by the first measurement resource configuration as the target resource based on the wake-up signal comprises:
based on the wake-up signal, determining that the target resource exists in resources configured by the plurality of measurement resource configurations, and determining the resource indicated by the first measurement resource configuration as the target resource.

4. The method according to claim 1 , further comprising:
performing measurement on the target resource.

5. The method according to claim 1 , wherein when the wake-up signal is not detected on a pre-configured resource, the method further comprises:
determining configuration information of the target resource based on any one of the following:
pre-configured information; or
a pre-defined rule.

6. The method according to claim 1 , wherein the target resource further comprises a paging resource and when the wake-up signal is not detected on a pre-configured resource, the method further comprises:
determining whether it is necessary to detect paging based on any one of the following:
pre-configured information; or
a pre-defined rule.

7. A resource indication method, comprising:
sending a wake-up signal to a terminal,
wherein an indication field included in the wake-up signal is used to indicate a first measurement resource configuration,
wherein the first measurement resource configuration comprises one of a plurality of measurement resource configurations notified to the terminal by using a Radio Resource Control (RRC) message,
wherein a resource indicated by the first measurement resource configuration is determined as a target resource, and the target resource comprises a measurement resource, and
wherein the measurement resource comprises a measurement resource of a Channel State Information Reference Signal (CSI-RS) for performing a CSI-RS measurement.

8. The method according to claim 7 , wherein the wake-up signal is used to implicitly indicate that the target resource exists in resources configured by the plurality of measurement resource configurations when wake-up is indicated; or
the wake-up signal is used to implicitly indicate that the target resource does not exist in the resources configured by the plurality of measurement resource configurations when wake-up is not indicated.

9. A communications device, comprising:
a memory storing computer-readable instructions; and
a processor coupled to the memory and configured to execute the computer-readable instructions, wherein the computer-readable instructions, when executed by the processor, cause the processor to perform operations comprising:
detecting, by a terminal, a wake-up signal; and
determining, by the terminal, a resource indicated by a first measurement resource configuration as a target resource based on the wake-up signal,
wherein the first measurement resource configuration comprises one of a plurality of measurement resource configurations notified to the terminal by using a Radio Resource Control (RRC) message, and is indicated by an indication field included in the wake-up signal, and
wherein the target resource comprises a measurement resource, and the measurement resource comprises a measurement resource of a Channel State Information Reference Signal (CSI-RS) for performing a CSI-RS measurement.

10. The communications device according to claim 9 , wherein the operations further comprise:
when the wake-up signal indicates wake-up, determining that the target resource exists in resources configured by the plurality of measurement resource configurations; or
when the wake-up signal does not indicate wake-up, determining that the target resource does not exist in the resources configured by the plurality of measurement resource configurations.

11. The communications device according to claim 9 , wherein determining the resource indicated by the first measurement resource configuration as the target resource based on the wake-up signal comprises:
based on the wake-up signal, determining that the target resource exists in resources configured by the plurality of measurement resource configurations, and determining the resource indicated by the first measurement resource configuration as the target resource.

12. The communications device according to claim 9 , wherein the operations further comprise:
performing measurement on the target resource.

13. The communications device according to claim 9 , wherein when the wake-up signal is not detected on a pre-configured resource, the operations further comprise:
determining configuration information of the target resource based on any one of the following:
pre-configured information; or
a pre-defined rule.

14. The communications device according to claim 9 , wherein the target resource further comprises a paging resource, and when the wake-up signal is not detected on a pre-configured resource, the operations further comprise:
determining whether it is necessary to detect paging based on any one of the following:
pre-configured information; or
a pre-defined rule.

15. The method according to claim 1 , wherein the target resource further comprises a paging resource.

16. The method according to claim 15 , further comprising:
performing paging on the target resource.

17. The method according to claim 1 , wherein detecting, by the terminal, the wake-up signal comprises:
receiving, by the terminal, the wake-up signal from a base station by detecting a Physical Downlink Control CHannel (PDCCH).

18. The communications device according to claim 9 , wherein detecting, by the terminal, the wake-up signal comprises:
receiving, by the terminal, the wake-up signal from a base station by detecting a Physical Downlink Control CHannel (PDCCH).
