In a specific frequency chunk (FC) and frequency resource block (FRB), the UE can search for a reference signal, which can be a synchronization signal (SS) used to perform one or more radio operations. Examples of radio operations are cell detection, time and/or frequency synchronization aka time and/or frequency synchronization tracking, RRM measurements, positioning, radio link monitoring, etc. In some examples, the reference signal can be (1) an NR-SS (NR-PSS/NR-SSS) encoding the physical cell identifier in NR; (2) a demodulation reference signal (DMRS) which may be further associated with a specific channel e.g. PBCH DMRS or data DMRS; and/or (3) a CSI-RS that could either implicitly or explicitly encode a beam identifier. While some examples below describe the NR-SS as the RS, the RS can also be one of the other RSs shown above or, there can be multiple RS configurations with the FC and FRB configured per RS.

According to an example embodiment, a method in a radio access network (RAN) and/or a method in a UE includes the UE performing measurements on a specific carrier frequency and/or a specific frequency chunk within that specific carrier frequency according to a measurement configuration provided to the UE by the network node. The chunk configuration may be signaled by the network node or may be pre-defined or derived/determined by the UE. The chunk configuration may further depend on UE capability, e.g., chunk size or the number of chunks or the set or the number of carriers associated with a chunk, etc.

According to another example embodiment, a method in a radio access network (RAN) and/or a method in a UE includes the UE performing measurement reporting for measurements on a specific carrier frequency and a specific frequency chunk within that specific carrier frequency according to a measurement configuration provided to the UE by the network node.
