Sensing-assisted channel estimation

An apparatus comprising:

• a processor;
• and
• a non-transitory memory including instructions that, when executed by the processor, cause the apparatus to:
• receive an indication of a plurality of sensing signal parameters of a sensing signal;
• receive the sensing signal, wherein the sensing signal comprises a linear chirp signal, the linear chirp signal including a prefix, wherein the plurality of sensing signal parameters includes a frequency component associated with a transmitter node;
• and
• transmitting to the transmitter node a channel parameter obtained by processing the received sensing signal.

A method of estimating channel parameters for a wireless channel between a transmitter node and a receiver node, the method comprising:

• transmitting, by the transmitter node, an indication of a plurality of sensing signal parameters of a sensing signal;
• transmitting, by the transmitter node, the sensing signal wherein the sensing signal comprises a linear chirp signal, the linear chirp signal including a prefix, wherein the plurality of sensing signal parameters includes a frequency component associated with the transmitter node;
• and
• receiving, by the transmitter node, a channel parameter from the receiver node.
