1. A system configured for Wi-Fi sensing, the system comprising:
a sensing initiator including at least one transmitting antenna, at least one receiving antenna, and at least one processor, wherein the at least one processor is configured to execute instructions to:
cause the at least one transmitting antenna to transmit a sensing trigger message including spatial stream information for a sensing transmission configured for making a motion sensing measurement in a sensing space;
receive, via the at least one receiving antenna, the sensing transmission from a sensing responder, the sensing transmission being triggered by the sensing trigger message and being in accordance with the spatial stream information; and
generate a sensing measurement indicative of presence or motion in the sensing space based on the sensing transmission transmitted in accordance with the spatial stream information.
