PHY layer sits at the bottom of the 5G NR protocol stack, interfacing to MAC sublayer higher up via transport channels. 1, there are three different ways of adding SCGs to the LTE anchor cell as follows. Compared with LTE, the spectrum efficiency of 5G New Radio (NR) is improved by 5~15 times with key performance indicators of user experience, connection density, and latency. In addition, NR-DC can also be used when a UE is connected to two gNB-DUs, one serving the MCG and the other serving the SCG, connected to the same gNB-CU, acting both as a MN and as a SN. The reason for the term cell group is to cover also the case of carrier aggregation where there are multiple cells, one per aggregated carriers, in each cell group. C) 载波. In addition to this, 5G also has to handle the new service requirement set by the industry, from use cases such as extreme MBB, URLL and mMTC. 2-1: Radio Protocol Architecture for split bearer and SCG bearer in Option 3/3ain 3GPP TR 38. on defining the MCG/SCG split bearers as an equivalent single bearer for the UE function to reduce in specifications the types of bearers that the UE must support. 2.
