In order to meet the high throughput demand set by international mobile telecommunication union, carrier aggregation is exploited for expanding the bandwidth of up to 100 MHz in Long Term Evolution-Advanced (LTE-A). For achieving the aforementioned bandwidth, a maximum of five component carriers (CCs) can be aggregated as per Release 10 LTE-A. Improper CC selection and scheduling will result in hazardous...
For the sake of augmented high throughput demand of users, carrier aggregation is employed for escalating the bandwidth in LTE-Advanced. According to the latest LTE-Advanced release, maximum of five component carriers (CC) can be combined. Due to variable interference on CCs, proper CC selection plays a key role in the overall performance of the network. We propose particle swarm optimization, a metaheuristic...
Cognitive radio (CR) is a novel methodology that facilitates unlicensed users to share a licensed spectrum without interfering with licensed users. This intriguing approach is exploited in the Long Term Evolution-Advanced (LTE-A) network for performance improvement. Although LTE-A is the foremost mobile communication standard, future underutilization of the spectrum needs to be addressed. Therefore,...
