Carrier Aggregation (CA) is one of the important technologies to further improve the capacity of Long Term Evolution Advanced (LTE-A). When CA is conducted, a User Equipment (UE) will firstly select a Primary Serving Cell (PCell) for mobility support and then add Secondary Serving Cells (SCell) for higher experienced data rate. When and how to add/remove SCell is a very important issue, especially...
This paper focuses on investigating appropriate management of Component Carriers(CCs) in carrier aggregation( CA) system, which is identified as one of the most distinct features of 4G systems including Long Term Evolution- Advanced (LTE-A). An LTE-A user equipment (UE) is allowed to concurrently utilize multiple carriers, which leads to scalable increase in user throughput. However, in certain circumstances,...
CoMP JP (Coordinated Multi-Point Joint Processing) is regarded as a promising technique to improve both cell edge user throughput and cell average user throughput in LTE-A downlink. CoMP JP can be categorized as CoMP JT (Joint Transmission) and COMP DCS (Dynamic Cell Selection). Compared with CoMP JT schemes, CoMP DCS provides a good trade-off between the transmission algorithm complexity, backhaul...
Coordinated Multi-Point (CoMP) transmission is considered for Long Term Evolution - Advanced (LTE-A) as an effective method to improve both average and cell-edge throughput. However, most of current research on CoMP with Multi-User (MU)-MIMO are under ideal assumption. In this paper, we study CoMP under realistic conditions, including limited feedback and complexity. Taking both performance and complexity...
