1. WF on NAICS Receiver Terminology
3GPP TSG-RAN WG4 Meeting #66bis

Agenda Item: 9.7.2 R
WF on NAICS Receiver Terminology
Qualcomm, […]

2. General We list various receiver types for information purpose.
Each receiver type may operate under various degrees of knowledge of interferer parameters
Each receiver type may be applicable for dealing with inter-cell, intra-cell, or inter-stream interference.

3. IS Receivers LMMSE-IRC: baseline for Rel-11 MMSE-IRC study
Enhanced LMMSE-IRC (E-LMMSE-IRC): MMSE-IRC that explicitly considers interferer channel estimates and other interferer knowledge
Widely linear MMSE-IRC (WLMMSE-IRC): as proposed in R

4. ML-Receivers
ML: full-blown joint detection of useful and interference signals in accordance to the ML criterion
Low complexity ML (L-ML): reduced complexity joint detection of useful and interference signals in accordance to the ML criterion (e.g. sphere decoding, QR-MLD, MLM, etc.)

5. IC Receivers
Code word level SIC (CWIC): receiver utilizing successive application of linear detection, decoding, re-encoding, and cancellation
May have iteration (e.g. Turbo CWIC)
May utilize CRC check (e.g. hard CWIC)
ML-CWIC: receiver utilizing successive application of ML or low complexity ML detection, decoding, re-encoding, and cancellation
Symbol level IC (SLIC): successive cancellation receiver utilizing successive application of linear detection, reconstruction, and cancellation
May have iteration
Parallel interference cancellation (PIC): parallel IC, otherwise similar to SIC

6. Next step
Companies are encouraged to bring results for their choices of receiver types. The results may include
Performance evaluation
Complexity
Required interferer parameter knowledge
Other relevant aspects
The performance evaluation may include
Evaluation under genie-aided knowledge of interferer parameters
Evaluation under no network assistance
May perform blind detection of interferer parameters
