Summary of Agreements by Topic

1. Evaluation on Low Power WUS

• Evaluation Methodology:
• Performance metrics include power consumption, latency, coverage, and robustness.
• Power models for LP-WUR include "Ultra-deep sleep" and "On/Off" states with specific relative power values and transition energy assumptions.
• FAR (False Alarm Rate) and MDR (Miss Detection Rate) targets are defined for evaluation purposes.
• Coverage evaluation uses MIL (Maximum Isotropic Loss) as a metric, with scenarios including urban, rural, and long-distance rural environments.
• Reference NR channels for comparison include PDCCH for paging and PUSCH for message3.
• Power Consumption:
• LP-WUR power states are categorized into "Off" and "On" with relative power values ranging from 0.001 to 4 units.
• Transition energy and ramp-up times are specified for evaluation purposes.
• Latency:
• Defined as the interval between data arrival at gNB and UE response, including sync/re-sync times.
• Coverage:
• MIL margin is used to compare LP-WUS with NR reference channels.
• Observations include differences in assumptions for antenna gain corrections and HARQ configurations.
• System Impact:
• Metrics include system overhead, capacity impact, and network power consumption.

2. Low Power WUS Receiver Architectures

• Receiver Types:
• Three main architectures studied: RF envelope detection, heterodyne with IF envelope detection, and homodyne/zero-IF with baseband envelope detection.
• Observations on power consumption, noise figure, and sensitivity for each architecture.
• FSK Architectures:
• Parallel OOK receivers and frequency-to-amplitude conversion methods are studied for FSK waveforms.
• Baseband Processing:
• Techniques like Goertzel filters and FFT are considered for signal processing.
• Observations on power reduction compared to main radio.
• Multiplexing:
• LP-WUS can be flexibly configured within a carrier for multiplexing with other NR signals.

3. L1 Signal Design and Procedure

• Waveform Generation:
• Multiple waveforms studied, including OOK (Options 1-4), FSK (Options 1-2), and OFDMA.
• Observations on robustness to timing and frequency errors, spectral efficiency, and diversity techniques.
• Synchronization:
• LP-SS (Low Power Synchronization Signal) is beneficial for coarse time and frequency synchronization.
• LP-SS coverage should be equal to or better than LP-WUS.
• RRM Measurements:
• Metrics include LP-RSSI, LP-RSRP, LP-SINR, and LP-RSRQ.
• Relaxation of RRM measurements in MR is considered under certain conditions.
• Coverage Enhancement Techniques:
• Techniques include channel coding, spreading codes, time-domain repetition, frequency hopping, and power boosting.
• Activation/Deactivation:
• Options for LP-WUS monitoring activation/deactivation include signaling, preconfigured criteria, and UE implementation.

4. Conclusions

• Waveform Recommendations:
• OFDMA and OOK waveforms (with or without OFDMA sequences) are recommended for possible down-selection.
• System Impact:
• LP-WUS provides significant power-saving gains compared to legacy i-DRX operations under certain conditions.
• Flexibility:
• LP-WUS can be flexibly configured within a carrier, supporting multiplexing with other NR signals.

This summary captures the key agreements across evaluation, receiver architectures, signal design, and conclusions for the study on low-power wake-up signals and receivers for NR.
