Abstract

A configuration to enable a base station to adjust an error rate for paging and to advertise such error rate to UEs, in order to optimize or reduce network paging resources. The apparatus determines a target miss rate for paging on a downlink narrowband control channel. The apparatus transmits an indication of the target miss rate to one or more UEs. The indication is transmitted in system information or a dedicated downlink channel.

Claims (62)

1. A method of wireless communication performed by a user equipment (UE), comprising:

receiving, from a base station, a configuration indicating a target miss rate for a downlink narrowband control channel, the target miss rate corresponding to a rate at which the UE is allowed to miss a number of pages during at least a portion of a discontinuous reception (DRX) cycle; and

adjusting a number of wakeup signal (WUS) monitoring occasions in the DRX cycle based on the target miss rate for the downlink narrowband control channel.

2. The method of claim 1 , wherein the adjusting the number of WUS monitoring occasions comprises:

reducing a number of DRX ON periods in the DRX cycle; or

reducing a page monitoring in the DRX cycle for the downlink narrowband control channel.

3. The method of claim 1 , wherein the UE terminates monitoring a paging common search space (CSS) early based on the target miss rate.

4. The method of claim 1 , further comprising:

transmitting, to the base station, a reduced paging indication, wherein the reduced paging indication includes a capability of the UE to support reduced paging.

5. The method of claim 4 , wherein the reduced paging indication corresponds to at least one coverage enhancement (CE) level.

6. The method of claim 1 , wherein the target miss rate is received in system information from the base station.

7. The method of claim 1 , further comprising:

receiving, from the base station, a reduction of downlink narrowband control channel repetitions based on the target miss rate.

8. The method of claim 1 , further comprising:

receiving, from the base station, a configuration for non-uniform distribution of paging occasions corresponding to the target miss rate; and

monitoring for pages during the non-uniform distribution of the paging occasions.

9. An apparatus for wireless communication at a user equipment (UE), comprising:

a transceiver;

at least one processor; and

a memory, coupled to the transceiver and to the at least one processor, storing instructions thereon, which when executed by the at least one processor, cause the apparatus to:

receive, from a base station, via the transceiver, a configuration indicating a target miss rate for a downlink narrowband control channel, the target miss rate corresponding to a rate at which the UE is allowed to miss a number of pages during at least a portion of a discontinuous reception (DRX) cycle; and

adjust a number of wakeup signal (WUS) monitoring occasions in the DRX cycle based on the target miss rate for the downlink narrowband control channel.

10. The apparatus of claim 9 , wherein the instructions causing the apparatus to adjust a number of WUS monitoring occasions further cause the apparatus to:

reduce a number of DRX ON periods in the DRX cycle; or

reduce a page monitoring in the DRX cycle for the downlink narrowband control channel.

11. The apparatus of claim 9 , wherein the UE terminates monitoring a paging common search space (CSS) early based on the target miss rate.

12. The apparatus of claim 9 , wherein the instructions, which when executed by the at least one processor, further cause the apparatus to transmit, to the base station, via the transceiver, a reduced paging indication, wherein the reduced paging indication includes a capability of the UE to support reduced paging, and wherein the reduced paging indication corresponds to at least one coverage enhancement (CE) level.

13. The apparatus of claim 9 , wherein the target miss rate is received in system information from the base station.

14. The apparatus of claim 9 , wherein the instructions, which when executed by the at least one processor, further cause the apparatus to:

receive, from the base station, via the transceiver, a reduction of downlink narrowband control channel repetitions based on the target miss rate.

15. The apparatus of claim 9 , wherein the instructions, which when executed by the at least one processor, further cause the apparatus to:

receive, from the base station, via the transceiver, a configuration for non-uniform distribution of paging occasions corresponding to the target miss rate; and

monitor for pages during the non-uniform distribution of paging occasions.

16. A non-transitory computer-readable medium storing computer executable code, the code when executed by a processor cause the processor to:

receive, from a base station, a configuration indicating a target miss rate for a downlink narrowband control channel, the target miss rate corresponding to a rate at which a user equipment (UE) is allowed to miss a number of pages during at least a portion of a discontinuous reception (DRX) cycle; and

adjust a number of wakeup signal (WUS) monitoring occasions in the DRX cycle based on the target miss rate for the downlink narrowb and control channel.

17. The non-transitory computer-readable medium of claim 16 , wherein the code causing the processor to adjust a number of WUS monitoring occasions further causes the processor to:

reduce a number of DRX ON periods in the DRX cycle; or

reduce a page monitoring in the DRX cycle for the downlink narrowband control channel.

18. The non-transitory computer-readable medium of claim 16 , wherein the code, which when executed by the processor, further cause the processor to terminate monitoring a paging common search space (CSS) early based on the target miss rate.

19. The non-transitory computer-readable medium of claim 16 , wherein the code, which when executed by the processor, further cause the processor to transmit, to the base station, a reduced paging indication, wherein the reduced paging indication includes a capability of the UE to support reduced paging, wherein the reduced paging indication corresponds to at least one coverage enhancement (CE) level.

20. The non-transitory computer-readable medium of claim 16 , wherein the target miss rate is received in system information from the base station.

21. The non-transitory computer-readable medium of claim 16 , wherein the code, which when executed by the processor, further cause the processor to:

receive, from the base station, a reduction of downlink narrowband control channel repetitions based on the target miss rate.

22. The non-transitory computer-readable medium of claim 16 , wherein the code, which when executed by the processor, further cause the processor to:

receive, from the base station, a configuration for non-uniform distribution of paging occasions corresponding to the target miss rate; and

monitor for pages during the non-uniform distribution of paging occasions.

23. An apparatus for wireless communication, comprising:

means for receiving, from a base station, a configuration indicating a target miss rate for a downlink narrowband control channel, the target miss rate corresponding to a rate at which a user equipment (UE) is allowed to miss a number of pages during at least a portion of a discontinuous reception (DRX) cycle; and

means for adjusting a number of wakeup signal (WUS) monitoring occasions in the DRX cycle based on the target miss rate for the downlink narrowband control channel.

24. The apparatus of claim 23 , wherein the means for adjusting the number of WUS monitoring occasions is further configured to:

reduce a number of DRX ON periods in the DRX cycle; or
