n. The EIRP limit per se cannot control the total amount of interference in the network, whereas a TRP requirement limits the total amount of interference in the network regardless of the specific implementation. In the case of passive systems, the antenna gain does not noticeably vary between the desired signal and the unwanted emissions. Thus EIRP is directly proportional to TRP and can be used interchangeably. For an active system such as NR, the EIRP may vary considerably between the desired signal and the unwanted emissions and also between implementations, thus EIRP (in this case) is not proportional to TRP and should not substi- tute TRP [10]. The RF requirements in FR2 bands are specified separately for devices, because of the high- er number of antenna elements for operation in FR2 and the high level of integration when mmWave technologies are used. In general, the RF requirements in FR2 are the same as the conducted RF requirements for FR1; however, the limits for certain requirements might be different. The difference in coexistence in mmWave bands leads to relatively relaxed requirements on ACLR and spectrum mask, which was demonstrated through coexistence studies performed in 3GPP. The mmWave implementations are more challenging than the more mature technologies in the frequency bands below 6 GHz. It should be noted that the channel bandwidths and numerologies supported in FR2 (see Table 5.1) are different from New Radio Access RF and Transceiver Design Considerations those used in FR1, making the comparison of the requirement levels, especially those related to the receiver somewhat difficult. The following is a list of the radiated RF require- ments in FR2 [3,10]: Output power level: The maximum output power is expressed as TRP and/or EIRP. In FR2, the minimum output power and transmitter OFF power levels are higher than those in FR1. The radiated transmit power is an additional requirement, which unlike the maximum output power, is directional. Transmitted signal quality: Frequency error and EVM r
