The objective of this study is to evaluate the feasibility and potential performance improvements of interference
cancellation/mitigation techniques for LTE/ LTE-Advanced FDD and TDD UE receivers, based on realistic network
scenarios. Scope of the work includes:
Identify realistic deployment scenarios, traffic models, interference models, and performance metrics to evaluate
the performance of advanced receiver to mitigate inter-cell interference.
Evaluation should be based on realistic modelling of inter-cell interference, including both synchronous and
asynchronous operations among macro eNBs, different precoders, ranks and powers applied over consecutive
subframes, and effect of CRS and control channels to which different precoder is applied compared with data
Study and evaluate feasibility and potential gain by advanced receiver at link and system levels:
Identify the scenarios and conditions where inter-cell interference mitigation is effective
Identify the receiver structures that could be a baseline to specify performance requirement.
Receiver structures targeting spatial domain interference mitigation such as IRC are to be considered as a
Receiver structures targeted to TDM-eICIC are only to be studied under the eICIC enhancements WI.
Details of interference modelling for performance requirements and conformance testing shall be
specified in the WI phase. Some complexity considerations should be taken into account during the SI
phase to avoid over simplified model later on that doesn't reflect the performance benefits found.
