Abstract:
Some embodiments of this disclosure include apparatuses and methods for implementing a requirement negotiation for an error vector magnitude (EVM) (or other metrics for measuring transmission signal quality) for ranging and/or positioning operation(s). Some embodiments relate to an electronic device including a transceiver and one or more processors communicatively coupled to the transceiver. The one or more processors transmit, during a negotiation phase of a ranging operation, an initial request frame to a second electronic device, wherein the initial request frame comprises a first indication of an error vector magnitude (EVM) requirement. The one or more processors receive an initial response frame from the second electronic device and determine a second indication of the EVM requirement based at least in part on the received initial response frame. The one or more processors implement a measurement phase of the ranging operation in accordance with the second indication of the EVM requirement.
