1. A method comprising:
determining one or more active slots and inactive slots in an ultra-wide band (UWB) ranging round;
determining multiple 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 ranging round and (ii) grouping each set of contiguous inactive slots into one of the multiple silent periods;
determining a target silent period in the ranging round, among the multiple silent periods, to be used for WiFi communication;
determining multiple target wake time (TWT) parameters such that a TWT session period defined by the TWT parameters overlaps with the target silent period;
determining one or more second silent periods preceding the target silent period in which the TWT parameters can be negotiated with an access point (AP) for the WiFi communication; and
negotiating the TWT parameters with the AP during the one or more second silent periods.
