1. A method at a base station of enabling radiofrequency (RF) sensing in a wireless communication network, the method comprising:
sending, from the base station to a user equipment (UE), a message indicating that an RF sensing signal is to be used for the RF sensing, wherein the message indicates:
(i) the RF sensing signal comprises a modified synchronization signal block (SSB) for supporting both sensing and initial access/mobility, or
(ii) the RF sensing signal comprises a non-SSB sensing reference signal (S-RS) of a secondary cell (Scell) and has a quasi co-location (QCL) relationship with a root SSB of a primary cell (Pcell); and
transmitting the RF sensing signal.
