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 an evolved NodeB (eNB) comprising:

memory; and

processing circuitry to;

decode a request from a user equipment (UE) to use extended idle mode DRX, the request including requested values for extended idle mode DRX parameters;

encode a system information block (SIB), for transmission to the UE indicating whether the eNB supports extended idle mode DRX;

provide the request to a Mobility Management Entity (MME) in a non-access stratum (NAS) message;

decode a response from the MME indicating acceptance of the request; and

provide paging to the UE according to requested values in accordance with the extended idle mode DRX parameters.

2. The apparatus of claim 1, wherein the MME acceptance includes revised values for the extended idle mode DRX parameters.

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 processing circuitry is configured to:

direct the UE directed to a different cell if the eNB does not support extended idle mode DRX.

5. A non-transitory computer-readable storage medium that stores instructions for execution by processing circuitry of an evolved NodeB (eNB), the instructions to configure the eNB to:

decode a request from a user equipment (UE) to use extended idle mode DRX, the request including requested values for extended idle mode DRX parameters;

encode a system information block (SIB), for transmission to the UE indicating whether the eNB supports extended idle mode DRX;

provide the request to a Mobility Management Entity (MME) in a non-access stratum (NAS) message;

decode a response from the MIME indicating acceptance of the request; and

provide paging to the UE according to requested values in accordance with the extended idle mode DRX parameters.

6. The non-transitory computer-readable storage medium of claim 5, wherein the MME acceptance includes revised values for the extended idle mode DRX parameters.

7. The non-transitory computer-readable storage medium of claim 5, wherein the NAS message includes one of an attach message, a routing area update (RAU) message, and a tracking area update (TAU) message.

8. The non-transitory computer-readable storage medium of claim 5, wherein the processing circuitry is configured to:

direct the UE directed to a different cell if the eNB does not support extended idle mode DRX.
