Discontinuous reception mode with two-stage wake-up

An article of manufacture comprising:

• a non-transitory computer-readable medium having stored therein instructions for providing power-conserving operation of user equipment (UE) in a cellular communication network, wherein the instructions are executable by a processor of the UE to:
• monitor, in a reduced power mode, for different signals during low power operation of a pre-wake up (PWU) stage of a multiple stage wake up (WU) process, the WU process comprising low power processing of one or more signals received by the UE in the PWU stage, the different signals configured to either transition one or more receivers of a UE from low power operation to operation configured to receive and transmit data during an ON duration of a WU stage of the multiple stage WU process or end a cycle of the multiple stage WU process without performing the WU stage of the multiple stage WU process, wherein one of the different signals is configured to indicate that data for the UE is expected during the ON duration of the WU stage following the PWU stage, wherein a power level associated with the reduced power mode is intermediate to power level associated with UE operation during the low power operation and power level associated with UE operation during the ON duration of the WU stage;
• transition the one or more receivers of the UE from the low power operation to the operation configured to receive and transmit data during the ON duration of the WU stage of the multiple stage WU process when it is determined that the one or more receivers are to be transitioned to the operation configured to receive and transmit data during the ON duration based on the monitoring for the one of the different signals in the PWU stage detecting the one of the different signals;
• and
• end a current cycle of the multiple stage WU process without performing the WU stage when it is determined that the one or more receivers are not to be transitioned to the operation configured to receive and transmit data during the ON duration based on the monitoring for the one of the different signals in the PWU stage failing to detect the one of the different signals.

An apparatus for providing power-conserving operation of user equipment (UE) in a cellular communication network, the apparatus comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor, wherein the at least one processor is configured:
• to monitor, in a reduced power mode, for different signals during low power operation of a pre-wake up (PWU) stage of a multiple stage wake up (WU) process, the WU process comprising low power processing of one or more signals received by the UE in the PWU stage, the different signals configured to either transition one or more receivers of a UE from low power operation to operation configured to receive and transmit data during the ON duration of a WU stage of the multiple stage WU process or end a cycle of the multiple stage WU process without performing the WU stage of the multiple stage WU process, wherein one of the different signals is configured to indicate that data for the UE is expected during the ON duration of the WU stage following the PWU stage, wherein a power level associated with the reduced power mode is intermediate to power level associated with UE operation during the low power operation and power level associated with UE operation during the ON duration of the WU stage;
• to transition the one or more receivers of the UE from the low power operation to the operation configured to receive and transmit data during the ON duration of the WU stage of the multiple stage WU process when it is determined that the one or more receivers are to be transitioned to the operation configured to receive and transmit data during the ON duration based on the monitoring for the one of the different signals in the PWU stage detecting the one of the different signals;
• and
• to end a current cycle of the multiple stage WU process without performing the WU stage when it is determined that the one or more receivers are not to be transitioned to the operation configured to receive and transmit data during the ON duration based on the monitoring for the one of the different signals in the PWU stage failing to detect the one of the different signals.
