Moreover, a large amount of LTE is deployed below 6GHz, and there are few sub-6GHz spectrums available for 5G. Therefore, NR must study the spectrum application above 6GHz, and the high frequency band has limited coverage and fast signal fading.

And this delay reduces the efficiency of CA usage and radio resources, especially in small cell deployment scenarios. In a dense small cell deployment scenario, the signaling load of each SCell is also very large, especially when each SCell needs to be configured separately. Therefore, the current CA architecture introduces additional delay, which limits the use of CA and reduces the gain of CA load sharing.
