Abstract

A system, network node and wireless device a provided. The wireless device receives, during an active time, downlink control information, DCI, having a predefined DCI format from the network node. The predefined DCI format includes at least one bit indicating that the DCI includes a go-to-sleep, GTS, indication. The wireless device is caused to enter a sleep state based at least in part on the GTS indication.

Claims (34)

1. A wireless device, comprising:

processing circuitry configured to:

receive, during an active time, downlink control information, DCI, having a predefined DCI format, the predefined DCI format including at least one bit indicating that the DCI includes a go-to-sleep, GTS, indication;

in response to receiving the DCI, cause the wireless device to skip a quantity of physical downlink control channel, PDCCH, monitoring occasions; and

cause the wireless device to enter a sleep state based at least in part on the GTS indication.

2. The wireless device of claim 1 , wherein the DCI further indicates for the wireless device to enter the sleep state one of after an indicated quantity of slots and after an indicated time duration.

3. The wireless device of claim 1 , wherein the processing circuitry is further configured to, in response to receiving the DCI, reconfigure at least one connected discontinuous reception, C-DRX, configuration.

4. The wireless device of claim 1 , wherein the processing circuitry is further configured to, in response to receiving the DCI, trigger reception of a physical downlink shared channel, PDSCH, transmission that includes additional information for configuring the sleep state.

5. The wireless device of claim 4 , wherein the processing circuitry is further configured to, in response to receiving the DCI, cause the wireless device to enter the sleep state after the additional information has been received.

6. A method implemented by a wireless device, the method comprising:

receiving, during an active time, downlink control information, DCI, having a predefined DCI format, the predefined DCI format including at least one bit indicating that the DCI includes a go-to-sleep, GTS, indication;

in response to receiving the DCI, skipping a quantity of physical downlink control channel, PDCCH, monitoring occasions; and

causing the wireless device to enter a sleep state based at least in part on the GTS indication.

7. The method of claim 6 , wherein the DCI further indicates for the wireless device to enter the sleep state one of after an indicated quantity of slots and after an indicated time duration.

8. The method of claim 6 , further comprising, in response to receiving the DCI, reconfiguring at least one connected discontinuous reception, C-DRX, configuration.

9. The method of claim 6 , further comprising, in response to receiving the DCI, triggering reception of a physical downlink shared channel, PDSCH, transmission that includes additional information for configuring the sleep state.

10. The method of claim 9 , further comprising, in response to receiving the DCI, causing the wireless device to enter the sleep state after the additional information has been received.

11. A network node, comprising:

processing circuitry configured to:

configure downlink control information, DCI, having a predefined DCI format, the predefined DCI format including at least one bit indicating that the DCI includes a go-to-sleep, GTS, indication configured to be received by a wireless device during an active time and to cause the wireless device to enter a sleep state;

configure the DCI to cause the wireless device to skip a quantity of physical downlink control channel, PDCCH, monitoring occasions; and

cause transmission of the DCI to the wireless device.

12. The network node of claim 11 , wherein the processing circuitry is further configured to configure the DCI to cause the wireless device to enter the sleep state one of after an indicated quantity of slots and after an indicated time duration.

13. The network node of claim 11 , wherein the processing circuitry is further configured to configure the DCI to cause the wireless device to reconfigure at least one a connected discontinuous reception, C-DRX, configuration of the wireless device.

14. The network node of claim 11 , wherein the processing circuitry is further configured to cause a physical downlink shared channel, PDSCH, transmission that includes additional information for the wireless device to configure the sleep state.

15. The network node of claim 14 , wherein the processing circuitry is configured to configure the DCI to cause the wireless device to enter the sleep state after the additional information has been received.

16. A method implemented by a network node, the method comprising:

configuring downlink control information, DCI, having a predefined DCI format, the predefined DCI format including at least one bit indicating that the DCI includes a go-to-sleep, GTS, indication configured to be received by the wireless device during an active time and to cause the wireless device to enter a sleep state;

configuring the DCI including configuring the DCI to cause the wireless device to skip a quantity of physical downlink control channel, PDCCH, monitoring occasions; and

causing transmission of the DCI to the wireless device.

17. The method of claim 16 , wherein configuring the DCI further comprises configuring the DCI to cause the wireless device to enter the sleep state one of after an indicated quantity of slots and after an indicated time duration.

18. The method of claim 16 , wherein configuring the DCI further comprises configuring the DCI to cause the wireless device to reconfigure at least one connected discontinuous reception, C-DRX, configuration of the wireless device.

19. The method of claim 16 , further comprising causing a physical downlink shared channel, PDSCH, transmission that includes additional information for the wireless device to configure the sleep state.

20. The method of claim 19 , wherein configuring the DCI comprises configuring the DCI to cause the wireless device to enter the sleep state after the additional information has been received.
