Hi,
Has anybody worked on the NR Rel16 feature Wake Up Signal?

Think WUS was first introduced in LTE Rel15.
Could be, haven’t worked on it though.
I have questions on NR config.
Go ahead and ask.
I will try to help, if I can. Otherwise someone else from the community will do hopefully. 
Basically trying to understand how the IE ps-WakeUp works.
Does anybody has tested using this.
WPS (Wake up signal)
- Wake Up Signal is a kind of energy saving technology being used in LTE and NR. WUS is employed for Idle mode operation in LTE and is employed for connected mode in NR.
How UE saves Energy?
- When WUS is configured by eNB and the configuration is broadcasted by SIB, UE monitors WUS first without monitoring Paging. UE start monitors Paging only when it detects WUS. In this way, UE can save energy for waking up and monitors Paging signal by removing the unnecessary wake up.
Validation through Log:
Reference Amrisoft
- Step1: Check SIB message to verify WPS config parameter
sib2-r13: {
radioResourceConfigCommon-r13 {
rach-ConfigCommon-r13 {
preambleTransMax-CE-r13 n10,
powerRampingParameters-r13 {
powerRampingStep dB2,
preambleInitialReceivedTargetPower dBm-110
wus-Config-r15 {
maxDurationFactor-r15 oneHalf,
numPOs-r15 n4,
numDRX-CyclesRelaxed-r15 n1,
timeOffsetDRX-r15 ms80,
timeOffset-eDRX-Short-r15 ms80
- Step2: Verify Ue capability for WPS
wakeUpSignal-r15 true,
wakeUpSignalMinGap-eDRX-r15 ms40
- Step3: RRC Release–>Idle
Time: 12:58:18.017
Message: RRC connection release

rrc-TransactionIdentifier 0,
criticalExtensions c1: rrcConnectionRelease-r13: {

}
}
}
- Step4: Verify the PO estimated vs Actual Tx at PHY
