Strategy for Resource Allocation in LTE-A

An EUTRAN offers Multi-Point connectivity from base station (eNB) toward the UE for reliable connection under mobility. This enhances the user experience with committed throughput. Radio resource allocation is a complex arrangement of resources in multiuser scenario, and it became more cumbersome if UE offer optional or alternative path to connect the network. Generally in network radio resources are configured in the pool, however resources are offered to the user on the basis of “as and when require”. Multi-Point connectivity (Mu-PC) provides alternative radio resource, with different scheduling mechanism. This definitely reduces network capacity in whole, but at the same time increases resource availability per user at a given state of time. In each cycle of resource allocation a feedback mechanism work to cater operational resource requirement. In this paper, we have investigated the performance of EUTRAN under different strategies of resource allocation using MATLAB, from different schedulers such as round robin, proportional fair, best channel quality indicator (CQI), max transmission point (TP) and a resource fair. We evaluate strategies for resource allocation under indistinguishable arrangement and conclude that performance comprehensively depend upon channel imperfection.
