TRP and have less stringent limits relative to those in FR1. The ACLR is on the order of 15 dB and relaxed compared to FR1 due to more favorable coexistence conditions. Reference sensitivity and dynamic range: These are defined similar to those in FR1; however, the levels are not comparable. There is in addition a directional OTA sensitiv- ity requirement. Equivalent isotropic sensitivity is the sensitivity for an isotropic directivity device equivalent to the sensitivity of the discussed device exposed to an incoming wave from a defined AoA. 674 Chapter 5 Receiver susceptibility to interfering signals: ACS, in-band, and OOB blocking are defined in the same way as it was done for FR1; however, no narrowband blocking sce- nario is defined since there are only wideband systems in FR2. The ACS requirement is relaxed compared to FR1 due to more favorable coexistence condition. The RF characteristics of the receiver and transmitter of a BS or a device are defined by the RF requirements that are partly specified by 3GPP. The BS is the RAN node that transmits and receives RF signals on one or more antenna connectors. An NR BS, defined in RF spe- cifications [5], is not the same as a gNB, which is the corresponding logical node in the radio access network. However, the device in RF specifications is the same as the UE defined in RAN specifications [2,3,4]. The conducted RF requirements are defined for oper- ating frequencies in FR1, whereas only radiated (OTA) requirements are defined for FR2 bands. The set of conducted RF requirements defined for NR are essentially the same as those defined for LTE. Some of the requirements related to the frequency bands and/or the system deployment are technology-agnostic and are derived from regional regulatory requirements. The NR-specific requirements related to flexible channel bandwidths and multiple OFDM numerologies have certain implications on the transmitter requirements for unwanted emissions, where the definition of the limits depends on the channel bandwidth. Such limits wo
