Long Term Evolution-Advanced (LTE-A) has been recently agreed by the 3rd Generation Partnership Project (3GPP) as the next evolution of LTE. Relay, which could enhance the coverage and increase the data rates in a cost efficient manner, has been taken as a promising key technique in the LTE-A network to meet its demanding requirement. In 3GPP Release 10, Type-1 relay was agreed as a work item (WI)...
Long Term Evolution-Advanced (LTE-A) networks are termed as the 4G cellular systems. There are many novel techniques used in LTE-A systems to fulfill the target of 4G requirements such as Relay Node (RN), Carrier Aggregation (CA) and so on. Relay has been taken as a promising key technique in the LTE-A network to meet its demanding requirement which could enhance the coverage and increase the data...
Limited transmission power and short TTI length impose a bottleneck on LTE UL performance in a coverage-limited scenario. This paper presents an effective coverage enhancement mechanism called TTI bundling to boost uplink VoIP performance in LTE FDD mode. Performance evaluation for TTI bundling with VoIP traffic is carried out by semi-static system simulation, and the impact from different bundling...
