Detailed Description Fifth generation (5G) communication systems are ready to provide ever-increasing throughput to congested mobile user environments in the millimeter wave spectrum (above about 10 GHz) using micro and pico cellular networks. These frequencies provide higher bandwidths but operate under worse propagation conditions than lower frequencies traditionally used for wireless services, particularly in terms of robustness. To address these channel impairments, the 5G and NR cellular networks may configure the transmission links using reference signal mapping (e.g., by establishing highly directional transmission links) to maintain acceptable communication quality to users. In an example, the directional link where fine alignment of the transmitter and receiver beams is required is implemented by a set of operations called beam management. In multi-CC (component carrier ) aggregate transmission, for intra-band CA (in-band carrier aggregation, intra-band carrier aggregation), the RF (radio frequency) of the UE may be shared for multiple CCs within the band, and the UE receives beams simultaneously. This capability is also available when a single CC is used. These CCs belong to the same CC group, e.g. within the same frequency band or sharing the same antenna connector
