Procedures for wideband sensing via successive-in-time narrowband transmissions

An apparatus of wireless communication at a network entity, comprising:

• at least one memory;
• and
• at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor, individually or in any combination, is configured to:
• receive, from a user equipment (UE), a resource request for a successive-in-time sensing on a target object to obtain sensing information of the target object;
• allocate, for the UE, first resource for a first sensing signal, the first sensing signal having a first duration and at a first frequency band;
• and
• allocate, for the UE, second resource for a second sensing signal in combination with the first sensing signal, the second sensing signal having a second duration shorter than the first duration and at a second frequency band different than the first frequency band.

A method of wireless communication at a user equipment (UE), comprising:

• transmitting a first sensing signal having a first duration and at a first frequency band;
• obtaining a Doppler estimation of a target object based on a first reflection of the first sensing signal;
• transmitting a second sensing signal having a second duration shorter than the first duration and at a second frequency band different than the first frequency band;
• and
• performing a successive-in-time sensing, based on the Doppler estimation and a combination of the first reflection of the first sensing signal and a second reflection of the second sensing signal to obtain sensing information for the target object.
