Abstract
In this paper, we describe the coexistence technologies between legacy Wi-Fi and WUR Wi-Fi discussed in IEEE 802.11ba group, and perform a numerical evaluation of the wake-up latency considering the WUR signaling procedure and different load from co-existing legacy Wi-Fi devices. We consider two modes of operation for WUR capable devices, i.e. normal mode and duty cycle mode. The value of WUR ACK timeout does not critically affect the wake-up latency. Performance results also show that the duty cycle based operation mode is more preferable for low network load scenarios because it achieves similar delay performance with the normal mode, but requires less energy consumption. In contrast, the delay for duty cycle mode drastically increases with the load of co-existing legacy Wi-Fi network, but decreases more energy consumption.
