Abstract

Embodiments of wireless communication devices and method for discontinuous reception (DRX) mode in RRC_IDLE state of wireless communication are generally described herein. Some of these embodiments describe a wireless communication device having processing circuitry arranged to determine to use an extended paging discontinuous reception (DRX) value to increase a paging cycle length. The wireless communication device may transmit a non-access stratum (NAS) message to the network, indicating that the wireless communication device desires to use the extended paging DRX value. The wireless communication device may receive a message from the network that includes an information element (IE) indicating whether the network supports the extended paging DRX value. Other methods and apparatuses are also described.

Claims

1. An apparatus for a user equipment (UE), the apparatus comprising:

memory; and

processing circuitry to;

determine whether to use extended idle mode discontinuous reception (DRX) based on delay tolerance of communications;

decode a system information block (SIB) received from an evolved NodeB (eNB) indicating whether the eNB supports extended idle mode DRX;

encode a non-access stratum (NAS) message for transmission to the eNB indicating that the UE is requesting to use extended idle mode DRX;

receive an extended idle mode DRX cycle length in response to transmission of the NAS message if the network supports extended idle mode DRX; and

monitor for paging transmissions according to the extended idle mode DRX cycle length if the network supports extended idle mode DRX and continue to use regular DRX parameters otherwise.

2. The apparatus of claim 1, wherein the processing circuitry is configured to:

terminate use of extended idle mode DRX if the SIB indicates that the network does not support extended idle mode DRX.

3. The apparatus of claim 1, wherein the NAS message includes one of an attach message, a routing area update (RAU) message, and a tracking area update (TAU) message.

4. The apparatus of claim 1, wherein the NAS message includes an extended idle mode DRX parameters information element if the UE is requesting to use extended idle mode DRX.

5. The apparatus of claim 4, wherein the UE is configured to receive different values for the extended idle mode DRX parameters than those requested in the NAS message.

6. The apparatus of claim 2, wherein the UE is directed to a different cell if the SIB indicates that the network does not support extended idle mode DRX.

7. The apparatus of claim 1, further including:

two or more antennas.

8. The apparatus of claim 1, wherein the apparatus is included in a device configured to perform machine-type communications (MTC).

9. A non-transitory computer-readable storage medium that stores instructions for execution by processing circuitry of a user equipment (UE), the instructions to configure the UE to:

determine whether to use extended idle mode discontinuous reception (DRX) based on delay tolerance of communications;

decode a system information block (SIB) indicating whether an Evolved NodeB (eNB) supports extended idle mode DRX;

encode a non-access stratum (NAS) message for transmission to a network indicating that the UE is requesting to use extended idle mode DRX; and

monitor for paging transmissions according to an extended idle mode DRX cycle length received in response to transmission of the NAS message.

10. The non-transitory computer-readable storage medium of claim 9, wherein the instructions configure the UE to:

terminate use of extended idle mode DRX if the SIB indicates that the network does not support extended idle mode DRX.

11. The non-transitory computer-readable storage medium of claim 9, wherein the NAS message includes one of an attach message, a routing area update (RAU) message, and a tracking area update (TAU) message.

12. The non-transitory computer-readable storage medium of claim 9, wherein the NAS message includes an extended idle mode DRX parameters information element for indicating values preferred by the UE for extended idle mode DRX parameters.

13. The non-transitory computer-readable storage medium of claim 12, wherein the UE is configured to receive different values for the extended idle mode DRX parameters than those requested in the NAS message.

14. The non-transitory computer-readable storage medium of claim 13, wherein the UE is configured to receive redirection instructions redirecting the UE to a different cell when a serving cell does not supported extended idle mode DRX parameters requested in the NAS message.
