Jan 2017 Abstract In this contribution, two WUR use cases with different operation modes are discussed, and requirements are summarized for each use case. Yong CHENG, et. al., Huawei

UC1: Synchronized wakeup in sensor networks Jan 2017 UC1: Synchronized wakeup in sensor networks Scenario In home network，tens or even hundreds of battery driven sensors (STA) are connected to home AP for security, control, heating, etc. Sensors support real-time status checking via AP, besides periodical data reporting. Wakeup operation Home AP wakes up smart sensors for real-time status checking and/or configuration. Requirements The number of wakeup packets (WUPs) for each STA should be minimized to reduce channel occupation, considering the large number of STAs in the network. Synchronized wakeup should be supported by AP and STAs. AP may send periodical synchronization messages to WUR. WUR in STA may work in duty-cycle mode. AP may send WUP during STA WUR’s ON time. First WUP to WUR, then messages via main radio smart sensors Yong CHENG, et. al., Huawei

UC2: Unsynchronized wakeup for wearable devices Jan 2017 UC2: Unsynchronized wakeup for wearable devices Scenario For personal network, smartwatch and other wearables (STAs) are connected to smartphone. A smartwatch or medical sensors may make an emergency call via smartphone (rarely occur); Incoming calls or message notifications may be delivered to a smartwatch. Wakeup operation Smartphone wakes up smartwatch for incoming call or message notification. Smartwatch wakes up smartphone to make an emergency call. Requirements Both AP and STA need to be power-efficient. Unsynchronized mode should be supported by both AP and STA. Synchronization messages may be avoided. WURs in AP and STA may work in duty-cycle mode. AP may send multiple WUPs to wakeup STA, and vice versa. Hiking/running SoftAP with WUR STA/Wearable with WUR First WUP to WUR, then messages via main radio SoftAP and STA wake up each other Yong CHENG, et. al., Huawei

Summary of use case requirements Jan 2017 Summary of use case requirements Two different working modes for WUR wakeup operations Synchronized mode for sensor network with a large number of sensors/STAs. Unsynchronized mode for wearable devices with a few wearables/STAs. Synchronized mode AP may send periodical synchronization messages to WUR to maintain synchronization. WUR in STA may work in duty-cycle mode. AP may send WUPs during STA WUR’s ON time for wakeup. Unsynchronized mode Synchronization messages may be avoided. WURs in STA and AP may work in duty-cycle mode. AP may send multiple WUPs to wakeup STA, and vice versa. Yong CHENG, et. al., Huawei
