Abstract

Adaptive paging techniques for EC-capable devices are described. In one embodiment, for example, an apparatus may comprise at least one memory and logic for an evolved node B (eNB), at least a portion of the logic comprised in hardware coupled to the at least one memory, the logic to receive an S1 paging message comprising a user equipment (UE) identifier (ID) associated with a UE and an extended coverage (EC) capability indicator indicating that the UE is EC-capable and page the UE using an EC paging sequence based on receipt of the S1 paging message, the EC paging sequence to comprise a series of transmissions of a radio resource control (RRC) paging message, the logic to truncate the EC paging sequence based on a determination that the UE has responded to RRC paging. Other embodiments are described and claimed.

First claim

What is claimed is:

1. An apparatus, comprising:
processing circuitry; and
non-transitory computer-readable storage media having stored thereon instructions that, when executed by the processing circuitry, cause an evolved node B to:
identify user equipment (UE) to be paged based on an identifier comprised in a UE Paging Identity information element (IE) contained in a received S1 PAGING message;
determine that the UE supports operation in a coverage enhancement mode based on an indicator comprised in a UE Radio Capability for Paging IE contained in the S1 PAGING message, the UE Radio Capability for Paging IE to contain a UERadioPagingInformation radio resource control (RRC) message comprising the indicator; and
based on the determination that the UE supports operation in the coverage enhancement mode, page the UE according to an RRC paging procedure comprising a plurality of paging repetitions.

2. The apparatus of claim 1 , the S1 PAGING message to comprise a paging count value to indicate whether the S1 PAGING message corresponds to a first attempt to page the UE.

3. The apparatus of claim 1 , the UERadioPagingInformation RRC message to include a UE-RadioPagingInfo IE comprising the indicator.

4. The apparatus of claim 3 , the UE-RadioPagingInfo IE to comprise an indication of a UE category of the UE.

5. The apparatus of claim 3 , the UE-RadioPagingInfo IE to comprise an indication of a whether the UE is a category M UE.

6. The apparatus of claim 1 , the identifier to comprise an SAE Temporary Mobile Subscriber Identity (S-TMSI) associated with the UE.

7. The apparatus of claim 1 , the S1 PAGING message to comprise a cell global identity (CGI) for a most recent serving cell of the UE.

8. The apparatus of claim 1 , comprising:
a radio frequency (RF) transmitter to perform multiple transmissions of an RRC paging message according to the RRC paging procedure; and
at least one RF antenna coupled to the RF transmitter.

9. Non-transitory computer-readable storage media having stored thereon instructions that, when executed by processing circuitry of an evolved node B (eNB), cause the eNB to:
identify user equipment (UE) to be paged based on an identifier comprised in a UE Paging Identity information element (IE) contained in a received S1 PAGING message;
determine that the UE supports operation in a coverage enhancement mode based on an indicator comprised in a UE Radio Capability for Paging IE contained in the S1 PAGING message, the UE Radio Capability for Paging IE to contain a UERadioPagingInformation radio resource control (RRC) message comprising the indicator; and
based on the determination that the UE supports operation in the coverage enhancement mode, page the UE according to an RRC paging procedure comprising a plurality of paging repetitions.

10. The non-transitory computer-readable storage media of claim 9 , the S1 PAGING message to comprise a paging count value to indicate whether the S1 PAGING message corresponds to a first attempt to page the UE.

11. The non-transitory computer-readable storage media of claim 9 , the UERadioPagingInformation RRC message to include a UE-RadioPagingInfo IE comprising the indicator.

12. The non-transitory computer-readable storage media of claim 11 , the UE-RadioPagingInfo IE to comprise an indication of a UE category of the UE.

13. The non-transitory computer-readable storage media of claim 11 , the UE-RadioPagingInfo IE to comprise an indication of a whether the UE is a category M UE.

14. The non-transitory computer-readable storage media of claim 9 , the identifier to comprise an SAE Temporary Mobile Subscriber Identity (S-TMSI) associated with the UE.

15. The non-transitory computer-readable storage media of claim 9 , the S1 PAGING message to comprise a cell global identity (CGI) for a most recent serving cell of the UE.

16. A method, comprising:
identifying user equipment (UE) to be paged based on an identifier comprised in a UE Paging Identity information element (IE) contained in a received S1 PAGING message;
determining that the UE supports operation in a coverage enhancement mode based on an indicator comprised in a UE Radio Capability for Paging IE contained in the S1 PAGING message, the UE Radio Capability for Paging IE to contain a UERadioPagingInformation radio resource control (RRC) message comprising the indicator; and
based on the determination that the UE supports operation in the coverage enhancement mode, paging the UE according to an RRC paging procedure comprising a plurality of paging repetitions.

17. The method of claim 16 , the S1 PAGING message to comprise a paging count value to indicate whether the S1 PAGING message corresponds to a first attempt to page the UE.

18. The method of claim 16 , the UERadioPagingInformation RRC message to include a UE-RadioPagingInfo IE comprising the indicator.

19. The method of claim 18 , the UE-RadioPagingInfo IE to comprise an indication of a UE category of the UE.

20. The method of claim 18 , the UE-RadioPagingInfo IE to comprise an indication of a whether the UE is a category M UE.

21. The method of claim 16 , the identifier to comprise an SAE Temporary Mobile Subscriber Identity (S-TMSI) associated with the UE.

22. The method of claim 16 , the S1 PAGING message to comprise a cell global identity (CGI) for a most recent serving cell of the UE.
