vel is the EIS level in the RX beam peak direc- tion. In carrier aggregation and NR-LTE dual-connectivity scenarios, an additional relaxation is defined for the following cases: (1) band-combination-specific RIB for FR1 inter-band carrier aggregation; (2) aggregated Channel BW specific RIB for FR2 intra-band continuous carrier aggregation, that is, 0.5 dB for aggregated bandwidths greater than 800 MHz; and (3) band- combination-specific maximum sensitivity degradation (MSD) for the band impacted by har- monic interference and intermodulation interference for the carrier aggregation and E-UTRA- NR dual-connectivity (EN-DC) scenarios [14]. Note that 3GPP allows certain amount of self- desensitization when TX emissions fall into the receiver band in non-contiguous carrier aggre- gation transmissions. This is done by relaxing the reference sensitivity requirements by an amount known as MSD when the UE transmits at the maximum power. However, these approaches (MPR and MSD) adversely impact the uplink link budget and throughput and are not the most appealing solutions. Alternatively, one could utilize higher quality RF components with good linear characteristics, which may considerably increase the overall radio implementa- tion cost and size. 5.4 Radio Resource Management Specifications Radio resource management (RRM) specifications are developed by 3GPP to ensure that the mobile terminals can maintain robust and reliable connection(s) to one or more base sta- tions. The RRM specifications include mobility management, handover, cell quality mea- surements based on reference signals, or physical synchronization signals. For the purpose of handover to a neighbor cell or adding a new component carrier in carrier aggregation, the UE is required to conduct measurements on the neighboring cells signal quality using reference signal received power (RSRP) or reference signal received quality metrics (RSRQ). In LTE systems, all eNBs continuously transmit cell-specific reference signals (CRS), this would enable the terminals to
