Abstract
This disclosure describes methods, apparatus, and systems related to enhanced collaborative time of arrival operations for wireless communications. A device may send trigger frames and may receive one or more null data packets (NDPs) from respective anchor station devices at respective times. The device may send a first null data packet announcement (NDPA) indicating the respective times. The device may send a third NDP. The device may identify one or more uplink NDPAs received from the respective anchor station devices, the one or more uplink NDPAs indicating respective times of arrival of the NDPs at the respective anchor station devices. The device may send a location measurement report (LMR) protocol data unit (PDU).
