Abstract
This disclosure describes systems, methods, and devices related to Efficient Ranging Optimization. Wi-Fi peer-to-peer devices may exchange null data packets as part of a fine timing measurement procedure for device ranging operations without requiring a trigger frame to initiate the exchange, and may renegotiate the timing when the devices are to be available for subsequent exchanges for device ranging operations.
Claims20
An apparatus of an initiator station device for non-trigger-based (NTB) fine timing measurements for Wi-Fi peer-to-peer, the apparatus comprising processing circuitry coupled to storage, the processing circuitry configured to:
- cause to send, during a time window and based on an amount of time between a successful measurement during a previous time window and the time window, a null data packet announcement (NDPA) to a responder station device in a Wi-Fi peer-to-peer connection with the initiator station device, the NDPA announcing a first NDP to be sent by the initiator station device to the responder station device;
- cause to send the first NDP to the responder station device during the time window;
- identify a second NDP received from the responder station device during the time window;
- and
- identify a location measurement report (LMR) and an indication of a renegotiation of the amount of time,
- wherein the LMR and the indication of the renegotiation are received from the responder station device during the time window.
A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors of a responder station device for non-trigger-based (NTB) fine timing measurements for Wi-Fi peer-to-peer, result in performing operations comprising:
- identifying, during a time window and based on an amount of time between a successful measurement during a previous time window and the time window, a null data packet announcement (NDPA) received from an initiator station device in a Wi-Fi peer-to-peer connection with the responder station device, the NDPA announcing a first NDP to be sent by the initiator station device to the responder station device;
- identifying the first NDP received from the station device during the time window;
- cause to send a second NDP to the initiator station device during the time window;
- and
- cause to send, to the initiator station device, a location measurement report (LMR) and an indication of a renegotiation of the amount of time,
- wherein the LMR and the indication of the renegotiation are sent by the responder station device during the time window.
A method for non-trigger-based (NTB) fine timing measurements for Wi-Fi peer-to-peer, the method comprising:
- causing to send, by processing circuitry of an initiator station device and during a time window and based on an amount of time between a successful measurement during a previous time window and the time window, a null data packet announcement (NDPA) to a responder station device in a Wi-Fi peer-to-peer connection with the initiator station device, the NDPA announcing a first NDP to be sent by the initiator station device to the responder station device;
- causing to send, by the processing circuitry, the first NDP to the responder station device during the time window;
- identifying, by the processing circuitry, a second NDP received from the responder station device during the time window;
- and
- identifying, by the processing circuitry, a location measurement report (LMR) and an indication of a renegotiation of the first amount of time,
- wherein the LMR and the indication of the renegotiation are received from the responder station device during the time window.
