1. A method comprising:
determining one or more active slots and inactive slots in an ultra-wide band (UWB) ranging round;
determining multiple UWB silent periods in the ranging round based on an arrangement of the inactive slots by (i) determining multiple sets of contiguous inactive slots in the UWB ranging round and (ii) grouping each set of contiguous inactive slots into one of the multiple UWB silent periods;
determining a sleep-wake-up schedule that aligns with at least one selected silent period of the multiple UWB silent periods in the ranging round, the sleep-wake-up schedule to be used for Wi-Fi communication; and
waking up a Wi-Fi station (STA) for the Wi-Fi communication during the at least one selected silent period, then going back to sleep according to the sleep-wake-up schedule.
