The present document relates to techniques (e.g., devices and methods) for signalling, e.g., for new radio unlicensed (NR-U).
A user equipment (UE) exchanges control signals with a first cell and a second cell. The first cell is a licensed or unlicensed cell and the at least one second cell is an unlicensed cell. The UE exchanges control signals with the first cell and, meanwhile: receives assistance information assisting the UE in receiving at least one discovery reference signal, the assistance information including timing information regarding the timing of the at least one discovery reference signal periodically sent by the at least one second cell; perform measurement(s) on discovery reference signal as acquired by the UE, from the at least one second cell, using the timing information included in the assistance information.
