1. A method of wireless communication at a wireless node, comprising:
transmitting a request for assistance to sense an environment to an other wireless node;
receiving a response to the request from the other wireless node;
determining a line-of-sight (LOS) path to the other wireless node is at least partially occluded;
transmitting a request to configure an intermediary apparatus for reflection of a set of sensing signals based on the LOS path to the other wireless node being at least partially occluded;
configuring the intermediary apparatus to reflect signals between the wireless node and the other wireless node based on the LOS path to the other wireless node being at least partially occluded;
communicating the set of sensing signals with the other wireless node using the intermediary apparatus;
determining a distance between 1) the wireless node and the intermediary apparatus, or 2) The wireless node and the other wireless node; and
sensing an object based on a set of calculations associated with the set of sensing signals,
wherein the set of calculations comprises a time difference of arrival (TDoA) between at least two of the set of sensing signals.
