tive declarations can be considered. If the receiver is direction adaptable, in the sense that the receiver target can be redirected, then the declaration contains a receiver target redirection range in a specified receiver target direction. The EIS limit should be met within the redirection range, which is evaluated at five declared sensitivity RoAoA within that range. If the receiver is not adaptive to direction and thus one cannot redirect the receiver target, the declaration consists of a single sensitiv- ity RoAoA in a specified receiver target direction, in which the EIS limit should be met. Note that the OTA sensitivity is defined in addition to the reference sensitivity requirement, which exists both as conducted for BS type 1-H and radiated for BS type 1-O [1,10]. The RF requirements for BS type 2-O are radiated requirements for base stations in FR2. These requirements are identical to the radiated RF requirements defined for FR1 bands, except that the limits for many requirements are different. As for the device, the difference in coexistence at mmWave frequencies leads to more relaxed requirements on ACLR and adjacent channel selectivity (ACS). The implementation of mmWave technologies is more challenging compared to the more mature technologies in sub-6 GHz frequency bands. In the following, we provide an overview of the radiated RF requirements in FR2 bands [5,29]: Output power level: The maximum output power is the same for FR1 and FR2; how- ever, it is scaled from the conducted requirement and expressed as TRP. In addition, there is a directional radiated transmit power requirement. The dynamic range require- ment is defined similar to that of FR1. Transmitted signal quality: Frequency error, error vector magnitude (EVM), and time- alignment requirements are defined similar to those in FR1 and with the same limits. Radiated unwanted emissions requirements: Occupied bandwidth, spectrum mask, ACLR, and spurious emissions are defined similar to those for FR1. The latter features/ metrics are based on
