Abstract

Technology for communicating a discontinuous reception (DRX) reconfiguration is disclosed. In one method, a preferred power consumption configuration message is received, at an evolved node B (eNB) from a user equipment. The preferred power consumption configuration message may be a one-bit message using a first Boolean value to indicate a preferred power consumption configuration. A DRX reconfiguration request message may be received, from the UE, to reconfigure a DRX configuration of the UE to reduce a power consumption level of the UE. The DRX reconfiguration request message may be the one-bit message using a second Boolean value to indicate a DRX reconfiguration. The eNB may determine to reconfigure the DRX configuration of the UE based on the DRX reconfiguration request message. In addition, the eNB may perform the DRX reconfiguration at the UE by adjusting one or more parameters of the DRX configuration.

First claim

What is claimed is:

1. A user equipment (UE) operable to communicate a discontinuous reception (DRX) reconfiguration, the UE having computer circuitry configured to:
send, to a node, a preferred power consumption configuration message, the preferred power consumption configuration message being a one-bit message using a first Boolean value to indicate a preferred power consumption configuration;
determine, at the UE, a desired power consumption level relative to a power level of the preferred power consumption configuration; and
communicate, to the node, a DRX reconfiguration request message to reconfigure a DRX configuration of the UE to provide a reduced power consumption level, the DRX reconfiguration request message being the one-bit message using a second Boolean value to indicate a DRX reconfiguration.

2. The computer circuitry of claim 1 , further configured to receive, from the node, a Radio Resource Connection (RRC) reconfiguration message containing a request to reinitialize the DRX configuration, the request indicating that the eNB reconfigured the DRX configuration of the UE.

3. The computer circuitry of claim 1 , further configured to send the preferred power consumption configuration message to toggle between a default power consumption configuration and a lower power consumption configuration.

4. The computer circuitry of claim 1 , further configured to send the preferred power consumption configuration message, to the node, in a UE assistance information message.

5. The computer circuitry of claim 1 , wherein the first Boolean value to indicate the preferred power consumption configuration is “1” and the second Boolean value to indicate the DRX reconfiguration is “0”.

6. The computer circuitry of claim 1 , further configured to communicate the DRX reconfiguration request message, to the node, to reconfigure a default DRX configuration of the UE.

7. The computer circuitry of claim 1 , further configured to communicate the DRX reconfiguration request message, to the node, to reconfigure a lower power DRX configuration of the UE.

8. The computer circuitry of claim 1 , wherein the DRX configuration is reconfigured, at the UE, by adjusting at least one of: an inactivity timer, ON duration, short cycle, long cycle, and a number of consecutive short cycles.

9. The computer circuitry of claim 1 , wherein the UE includes an antenna, a touch sensitive display screen, a speaker, a microphone, a graphics processor, an application processor, internal memory, or a non-volatile memory port.

10. The computer circuitry of claim 1 , wherein the node is selected from a group consisting of a base station (BS), a Node B (NB), an evolved Node B (eNB), a baseband unit (BBU), a remote radio head (RRH), a remote radio equipment (RRE), or a remote radio unit (RRU).

11. A method for communicating a discontinuous reception (DRX) reconfiguration, the method comprising:
receiving, at an evolved node B (eNB) from a user equipment (UE), a preferred power consumption configuration message, the preferred power consumption configuration message being a one-bit message using a first Boolean value to indicate a preferred power consumption configuration;
receiving, from the UE, a DRX reconfiguration request message to reconfigure a DRX configuration of the UE to reduce a power consumption level of the UE, the DRX reconfiguration request message being the one-bit message using a second Boolean value to indicate a DRX reconfiguration;
determining, at the eNB, to reconfigure the DRX configuration of the UE based on the DRX reconfiguration request message; and
performing the DRX reconfiguration at the UE by adjusting one or more parameters of the DRX configuration.

12. The method of claim 11 , further comprising communicating, to the UE, a Radio Resource Connection (RRC) reconfiguration message containing a request for the UE to reinitialize the DRX reconfiguration.

13. The method of claim 11 , further comprising receiving the preferred power consumption configuration message to toggle between a default power consumption configuration and a lower power consumption configuration.

14. The method of claim 11 , further comprising receiving the preferred power consumption configuration message, from the UE, in a UE assistance information message.

15. The method of claim 11 , wherein the first Boolean value to indicate the preferred power consumption configuration is “1” and the second Boolean value to indicate the DRX configuration is “0”.

16. The method of claim 11 , further comprising receiving the DRX reconfiguration request message, from the UE, to reconfigure a default DRX configuration of the UE.

17. The method of claim 11 , further comprising receiving the DRX reconfiguration request message, from the UE, to reconfigure a lower power DRX configuration of the UE.

18. The method of claim 11 , further comprising performing the DRX reconfiguration at the UE by adjusting at least one of: an inactivity timer, ON duration, short cycle, long cycle, and a number of consecutive short cycles.

19. A wireless device for communicating a discontinuous reception (DRX) reconfiguration, the wireless device comprising:
a preferred power consumption configuration module configured to send, to an evolved node B (eNB), a preferred power consumption configuration message, the preferred power consumption configuration message being a one-bit message using a first Boolean value to indicate a preferred power consumption configuration;
a desired power consumption determination module configured to determine, at the UE, a desired power consumption level relative to a power level of the preferred power consumption configuration; and
a DRX reconfiguration module configured to communicate, to the eNB, a DRX reconfiguration request message to reconfigure a DRX configuration of the wireless device to provide a reduced power consumption level, the DRX reconfiguration request message being the one-bit message using a second Boolean value to indicate a DRX reconfiguration.

20. The wireless device of claim 19 , further comprising a receiving module configured to receive, from the eNB, a Radio Resource Connection (RRC) reconfiguration message containing a request to reinitialize the DRX configuration, the request indicating that the eNB reconfigured the DRX configuration of the wireless device.

21. The wireless device of claim 19 , wherein the preferred power consumption configuration module is further configured to send the preferred power consumption configuration message to toggle between a default power consumption configuration and a lower power consumption configuration.
