- Abstract
- Novel mmWave-based multi-spot beam cellular system was introduced as one of means to satisfy the capacity requirement of 5G mobile communications. Its structural characteristic was that the service area of base station was covered with spot beams formed by many beamforming antennas, and one beam can be composed of multiple beam component carriers (BCCs) divided into multiple sub-bands within one broadband bandwidth at the millimeter frequency. Dynamic cell configuration (DCC) as the best feature of the new cellular architecture is that one or more beam component carrier(s) belonging to the same subband (or layer) may be grouped and then BCCs of the same group can be operated as one cell. The dynamic cell configuration at each sub-band considering the relation among sub-bands is especially called multi-FA layered DCC (ML DCC). In this paper, we design two mobility management methods and evaluate the mobility performance at non-blockage environment using fixed mobility parameters on the assumption that pseudo macro cell via ML DCC is used as mobility anchor layer.
