...Although transferring the data channel only will incur less overhead and delay as compared with the traditional HO procedures, new signalling mechanisms are required to enable such lightweight HOs [110]....
[...]
...On the other hand, the signalling radio bearers and few DRBs are established at the MCs which manage all the DRBs even though the latter are established at the SC layer....
[...]
...Thus mobility robustness is considered as the main benefit of dual connectivity with control-data separation [110]....
[...]
...As the cell size decreases, mobility management becomes complex because the HOs will happen frequently even for low mobility users....
[...]
...In Cloud-HetNet, all cells (i.e., MCs and SCs) are connected to a Cloud-RAN in a star topology and they act as radio resource heads....

...A heterogeneous cellular system may consist of regular macro-cell base stations (BS) that typically transmit at a high power level and overlaid pico-cells, femtocells as well as relays, which transmit at substantially lower power levels [4]....
