What is the difference between eICIC vs eIMTA?

Hello Experts.

What is the difference between eICIC vs eIMTA?

eICIC : in interference management and mitigation, Co-channel scenarios, there are some features to alleviate the interference issue and also to support larger bias toward small cells R10.In particular, eICIC is enabled by 2 techniques: the almost blank subframces (ABS) and resource-restricted measurement. ABS reduces the interference from the macro to pico UEs. however the macro interference can not be completed eliminated in ABS. it is for second technique.

eIMTA: Further enhancements to LTE TDD for DL-UL interference management and traffic adaptation. It is dynamic and flexible resource configuration for TDD in consideration of traffic load.
At the moment all the eNB’s associated with a network has to transmit the same UL/DL pattern throughout out the system. With eIMTA, each eNodeB can decide the UL/DL pattern itself depending on the load.
