In various embodiments described herein, bandwidth (BW) includes a range of frequencies over which a node transmits to and/or receives signal from another node. The BW may also be called an operating bandwidth, channel bandwidth, system bandwidth, configured bandwidth, transmission bandwidth, cell bandwidth, cell transmission BW, carrier bandwidth, and so forth. The BW can be expressed in any one of the following: G1 MHz, G2 GHz, in in terms of number of physical channels (e.g. G3 resource blocks, G4 subcarriers etc). In one example the BW can include guard band while in another example, the BW can exclude guard band. For example, system or channel BW can include guard band while transmission bandwidth consists of BW without guard band. For simplicity term BW is used in the embodiments.

In various embodiments described herein, a frequency resource block (FRB) includes any type of frequency resource comprising one or more resource elements or subcarriers. The FRB may also be referred to as a resource block (RB), physical RB (PRB), virtual RB (VRB), and so forth.

The embodiments described herein are applicable to any multicarrier system wherein at least two radio network nodes can configure radio measurements for the same UE. One specific example scenario comprises a dual connectivity deployment with LTE PCell and NR PSCell. Another example scenario is a dual connectivity deployment with NR PCell and NR PSCell.
