Abstract

A method includes determining a parameter of a coverage enhancement policy employed by a communication system. The method also includes setting a timing configuration ( 371 - 373, 391 - 393, 605, 606 ) of a discontinuous reception cycle ( 370 - 2, 370 - 3 ) employed by a terminal ( 101 ) of the communication system depending on the parameter. The method also includes communicating a paging signal in accordance with the timing configuration ( 371 - 373, 391 - 393, 605, 606 ) of the discontinuous reception cycle ( 370 - 2, 370 - 3 ) and the coverage enhancement policy.

Claims (40)

1. A method, comprising:

determining a parameter of a coverage enhancement policy employed by a communication system,

setting a timing configuration of a discontinuous reception cycle employed by a terminal of the communication system depending on the parameter, and

communicating a paging signal in accordance with the timing configuration of the discontinuous reception cycle and the coverage enhancement policy,

wherein the timing configuration is set based on a default setting and a preconfigured mapping, wherein the preconfigured mapping maps the default setting to the timing configuration in accordance with the parameter of the coverage enhancement policy.

2. The method of claim 1 ,

wherein the parameter comprises a repetition level of multiple repetitions of signals communicated by the terminal.

3. The method of claim 1 , further comprising:

communicating, between an access node of the communication system and the terminal, control data indicative of at least one of the default setting and the mapping.

4. The method of claim 1 , wherein the parameter comprises a repetition level of multiple repetitions of signals communicated by the terminal,

wherein the default setting comprises a reference periodicity of the discontinuous reception cycle,

wherein the mapping comprises a repetition-level-dependent scaling factor of the reference periodicity.

5. The method of claim 1 ,

wherein the timing configuration comprises at least one of an ON duration, an OFF duration, and a periodicity of the discontinuous reception cycle.

6. The method of claim 1 ,

wherein the discontinuous reception cycle comprises a top-level discontinuous reception cycle having respective ON durations and OFF durations,

wherein the discontinuous reception cycle further comprises a sub-level discontinuous reception cycle having respective ON durations and OFF durations,

wherein an ON duration of the top-level discontinuous reception cycle comprises multiple ON durations of the sub-level discontinuous reception cycle,

wherein the timing configuration comprises the ON duration of the top-level discontinuous reception cycle.

7. The method of claim 1 ,

wherein the parameter comprises a repetition level of multiple repetitions of signals communicated by the terminal,

wherein the method further comprises:

based on the repetition level: determining a time duration available for decoding the multiple repetitions of the paging signal,

implementing a threshold comparison between the determined time duration and a predefined threshold,

wherein the timing configuration is set depending on a result of the threshold comparison.

8. The method of claim 1 ,

determining a mobility level of the terminal,

wherein the timing configuration is further set depending on the mobility level.

9. The method of claim 1 ,

determining a mobility level of the terminal, and

selectively executing said setting of the timing configuration based on the coverage enhancement policy depending on the CE level.

10. The method of claim 1 ,

wherein the parameter comprises at least one of a spreading factor, a checksum length, and a transmit power level.

11. A device configured to:

determine a parameter of a coverage enhancement policy employed by a communication system,

set a timing configuration of a discontinuous reception cycle employed by a terminal of the communication system depending on the parameter, and

communicate a paging signal in accordance with the timing configuration of the discontinuous reception cycle and the coverage enhancement policy,

wherein the timing configuration is set based on a default setting and a preconfigured mapping, wherein the preconfigured mapping maps the default setting to the timing configuration in accordance with the parameter of the coverage enhancement policy.

12. The device of claim 11 ,

wherein the device is a terminal or a base station of a cellular network.
