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.
