Abstract
Described herein are various wake-up procedures for user equipments (UEs). A UE may include a low power wake-up radio (LP-WUR) separate from a front end module (FEM). The LP-WUR may remain awake continuously (or at high-frequency intervals) and monitor for a wakeup signal, allowing the FEM to remain powered down in the absence of downlink data. When the LP-WUR detects a wakeup signal configured for the LP-WUR, the LP-WUR may be configured to wake up the FEM to receive incoming downlink data. Various network components may be configured to ensure UEs with LP-WURs receive corresponding wake-up signals.

Claim
1. A user equipment (UE) comprising:
a first receiver comprising a low power wake-up receiver (LP-WUR) to monitor a downlink channel for a LP-WUR wake-up signal from an eNodeB, the LP-WUR wake-up signal to comprise a narrow-band signal; and
a second receiver comprising a front end module (FEM), separate from the LP-WUR, to monitor a physical downlink control channel (PDCCH), the FEM comprising:
transmission circuitry to transmit signal data to the eNodeB indicating the UE includes the LP-WUR;
circuitry to execute a power saving mode (PSM) for the FEM to cease monitoring the PDCCH in response to a period of inactivity; and
circuitry to exit the PSM for the FEM to monitor the PDCCH in response to the LP-WUR receiving the LP-WUR wake-up signal from the eNodeB.
2. The UE of claim 1, wherein the LP-WUR is to monitor a fixed physical resource block (PRB) location on the downlink channel allocated for the LP-WUR wake-up signal.
3. The UE of claim 2, wherein the LP-WUR wake-up signal is modulated according to an on-off keying (OOK) tone.
4. The UE of claim 2, wherein the fixed PRB location is included in a primary frequency band.
5. The UE of claim 2, wherein the fixed PRB location is included in a secondary frequency band.
6. The UE of claim 1, wherein the LP-WUR wake up signal further includes a system architecture evolution (SAE)-Temporary Mobile Subscriber Identity (S-TMSI) identifying the UE.
7. The UE of claim 1, wherein the LP-WUR is to monitor the downlink channel for the LP-WUR wake-up signal periodically according to a first time interval, and the FEM further comprises circuitry to execute a discontinuous reception (DRX) mode for monitoring the PDCCH according to a second time interval, the second time interval less than the first time interval.
8. The UE of claim 1, further comprising:
one or more antennas communicatively coupled to the LP-WUR for monitoring the downlink channel for the LP-WUR wake-up signal from the eNodeB, and communicatively coupled to the FEM to transmit the signal to the eNodeB indicating the UE includes the LP-WUR.
9. The UE of claim 8, wherein the UE comprises a machine-type communications (MTC) device.
10. The UE of claim 8, wherein the one or more antennas comprise a first antenna for monitoring the downlink channel for the LP-WUR wake-up signal from the eNodeB, and an antenna to transmit the signal to the eNodeB indicating the UE includes the LP-WUR module.
