Efficient spectrum usageEfficient spectrum usage
To get wider spectrum bandwidth up to 100MHz
• Aggregation of fragmented spectrums
• Sharing of fragmented spectrums among several
systems
• Asymmetric UL and DL spectrum allocation
To attain another ‘bit/Hz’
• SU-MIMO for UL (2x2 or 2x4)
• Further enhancement of the current MIMO scheme
533
Reduced UE Reduced UE CComplexityomplexity, P, Power ower
consumptionconsumption
Balance between the system performance
And
UE complexity, power consumption
• Peak power consumption of an UE will be higher
• Enhanced dynamic control of reception bandwidth
• A multi-carrier UL transmission mode by UE near the eNB
– Enabling discontinuous resource allocation
– Easy utilization of MLD at eNB receivers
