Performance requirements of MMSE-IRC receiver for LTE BS
The present document should fulfil the following objectives:
- Phase I:
- Identify target deployment scenarios and agree on relevant network parameters. Both homogeneous deployment (macro cell only) and heterogeneous deployment (co-channel between macro cell and low power node) should be considered.
- Conduct system-level simulation to determine the inter-cell interference modelling methodology and other side conditions needed for link-level simulation, and link-level simulation to evaluate gain of MMSE-IRC over baseline receiver (MMSE receiver)
- Phase II:
- LTE BS MMSE-IRC receiver is assumed as the reference receiver structure for specifying the requirements.
- Demodulation RS based MMSE-IRC receiver can be considered as baseline, and practical and realizable implementation should be taken into account.
- Specify the enhanced demodulation performance requirements for verification of BS receiver's ability on inter-cell interference suppression.
- For PUSCH, specify enhanced demodulation performance requirements based on the reference receiver.
- For PUCCH, with lower priority, determine whether to specify enhanced demodulation performance requirements based on the reference receiver.
- Specify the enhanced conformance test requirements.
Note: The enhanced demodulation performance requirements only apply to the base station capable of MMSE-IRC receiver.
