In Long Term Evaluation (LTE)-Advanced system, Carrier Aggregation (CA) technique that provide substantial enhancement in data rate transmission for downlink and uplink over wider bandwidth have been proposed. The basic idea of CA technique is to aggregate several smaller contiguous or noncontiguous components, thus concurrent radio resources across(More)
There are always increasing demands of high speed data applications in wireless systems with fast and seamless access to voice and multimedia services and QoS guaranteed such as in Fourth Generation (4G) Long Term Evolution (LTE)-Advanced system. Moreover, as mobility speeds support is expected to reach up to 500 km/h, the handover will occur more frequent,(More)
The mobile WiMAX system is based on the IEEE 802.16m standard which is used to develop an advanced air interface (AAI) to meet the requirements for IMT-Advanced next generation networks , which are able to provide high speed access and are used to provide a rate of broadband data for low mobility scenarios up to 1 Gbit/sec. This paper investigates the(More)
Although LTE-Advanced system is targeted at enhancing the users’ throughput and increasing connection reliability, however user’s mobility tends to degrade the efficiency of the services and applications in terms of throughput degradation and outage probability reduction. Particularly this is during the handover from the source to the target eNBs.(More)
