November 2017 doc. : IEEE 802. 11 -17/1607 r 1 Background q WUR Beacon frame can be transmitted periodically to WURs for synchronization. § WUR Beacon interval, TWBI, is configurable (e. g. , 1 s, 2 s, 4 s, 6 s, etc). • TWBI is included in WUR Mode element. § WUR beacon frame comprises a Partial TSF field. • The size of the Partial TSF field is fixed (e. g. , 12 bits) § WUR beacon frame may only use the low data rate 62. 5 kbps. q The transmission time required for a WUR Beacon frame is about 1 ms. § Airtime occupied by WUR Beacon transmission is not trivial § It is critical to minimize WUR Beacon transmission.
