Abstract
The present disclosure is directed to simultaneous channel sounding on multiple MLO channels followed by determining phase and amplitude corrections based on channel impulse responses obtained on each MLO channel. The corrections are then used in subsequent extrapolation of channel sounding on one channel to another. In one aspect, a method includes transmitting, on each radio interface of a first multi-link device, a corresponding sounding probe to a second multi-link device; determining, by each radio interface of the first multi-link device, a corresponding channel impulse response based on the corresponding sound probe to yield a plurality of channel impulse responses; determining an offset between the plurality of channel impulse responses; and using the offset during a subsequent extrapolation of a sounding probe on one radio interface to a second radio interface of the first multi-link device.
