US 9,872,252 B1 · Discontinuous reception mode with multiple-stage wake-up

Abstract

Systems and method of embodiments herein operate to conserve battery power of user equipment (UE). Embodiments determine whether waking up a UE receiver would be beneficial and based on the determination, the UE either wakes up the receiver or returns to sleep. Embodiments determine whether to wake up the receiver by performing pre-wake up (PWU) operation which either wakes up the receiver in a low power mode or wakes up the UE's wake up receiver. It may be determined whether a wake up (WU) signal is received during a PWU stage. If a WU signal is received during the PWU stage the UE may perform a full wake up of the receiver. If a WU signal is not received the UE may return to idle mode. In embodiments, WU (Wake Up) DRX cycles are supplemented with a Full DRX (Discontinuous Reception) cycle.

Dependent claims

A method for providing power-conserving operation via a multiple stage wake up (WU) process of user equipment (UE), the method comprising:

transitioning one or more receivers of the UE from a low power sleep state to a communication ready state at a second stage of the multiple stage WU process based upon control signal monitoring by the UE in a pre-wake up (PWU) state of a first stage of the multiple stage WU process when it is determined that the one or more receivers of the UE are to be transitioned to the communication ready state at the first stage of the WU process, wherein the communication ready state provides a connection between the UE and another station in which the UE is configured to receive and transmit data communications, and wherein UE operation in the PWU state provides the control signal monitoring at a power level intermediate to UE operations in the low power sleep state and the communication ready state and
ending a cycle of the multiple stage WU process without performing the second stage of the WU process to transition the one or more receivers to the communication ready state when it is determined that the one or more receivers are not to be transitioned to the communication ready state at the first stage of the multiple stage WU process.

A non-transitory computer-readable medium having program code recorded thereon for providing power-conserving operation via a multiple stage wake up (WU) process of user equipment (UE), wherein when the program code is executed by one or more computers causes the one or more computers to:

transition one or more receivers of the UE from a low power sleep state to a communication ready state at a second stage of the multiple stage WU process based upon control signal monitoring by the UE in a pre-wake up (PWU) state of a first stage of the multiple stage WU process when it is determined that the one or more receivers of the UE are to be transitioned to the communication ready state at the first stage of the WU process, wherein the communication ready state provides a connection between the UE and another station in which the UE is configured to receive and transmit data communications, and wherein the UE operation in the PWU state provides the control signal monitoring at a power level intermediate to UE operations in the low power sleep state and the communication ready state;
and
end a cycle of the multiple stage WU process without performing the second stage of the WU process to transition the one or more receivers to the communication ready state when it is determined that the one or more receivers are not to be transitioned to the communication ready state at the first stage of the multiple stage WU process.

A apparatus for providing power-conserving operation via a multiple stage wake up (WU) process of user equipment (UE), 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 transition one or more receivers of the UE from a low power sleep state to a communication ready state at a second stage of the multiple stage WU process based upon control signal monitoring by the UE in a pre-wake up (PWU) state of a first stage of the multiple stage WU process when it is determined that the one or more receivers of the UE are to be transitioned to the communication ready stage at the first stage of the WU process, wherein the communication ready state provides a connection between the UE and another station in which the UE is configured to receive and transmit data communications, and wherein UE operation in the PWU state provides the control signal monitoring at a power level intermediate to UE operations in the low power sleep state and the communication ready state;
and
to end a cycle of the multiple stage WU process without performing the second stage of the WU process to transition the one or more receivers to the communication ready state when it is determined that the one or more receivers are not to be transitioned to the communication ready state at the first stage of the multiple stale WU process.
