Multi-User MIMO & Beam Forming with Carrier Aggregation for LTE- Advanced System

Recently, Long Term Evolution Networks is a very popular cellular communication network that provides a very high speed of download and upload data in various environments. Resource allocation using different techniques is the emerging research area in the field of LTE and LTE-Advanced networks. In this paper, we analyze the performance of the LTE advanced carrier aggregation scheduling with multi-users MIMO and Beamforming techniques. Further, carrier aggregation scheduling with multi-users MIMO and Beamforming schedule compared with the round-robin (RR), FFR, and BCQI scheduling techniques. The performance of carrier aggregation with the multi-user MIMO and Beamforming techniques significantly increased overall system throughputs and show gain in terms of spectral efficiency, user throughput, user cell edge throughput, and fairness index.

Carrier Aggregation for High Speed Data in LTE Advanced System

One of the most important features to migrate from LTE system to LTE-A system is Carrier aggregation. It is used to achieve high data rates of the order of 1Gbps. Furthermore an LTE Advanced user is backward compatible with LTE. Carrier aggregation is a multi carrier technique, where we will be combining unused SCC with the PCC that is allocated to the user equipment. By combining five component carriers, each of 20 Mhz, we can extend the bandwidth to 100 Mhz and hence achieve high data rates. In this paper we will analyze the performance of carrier aggregation and compare it with the conventional LTE system.
