For the FE-ICIC and/or CRS-IC features, what does the channel estimation algorithm look like? Is the interference cancellation only on the interfering cell(s) only or are there multiple iterations that include both the serving and interfering cells? How many iterations/what is the stopping criteria? How is it different between colliding CRS and non-colliding CRS?

For the NAICS or other non IRC based techniques that suppress intercell interference, what is the receiver that is used? Is it iterative interference cancellation or a reduced complexity maximum likelihood (R-ML) detector? If iterative interference cancellation, is the decoder within the iteration? Are there any techniques in the iterations which are suboptimal but are meant to reduce complexity? If R-ML, which particular R-ML technique is used? Please provide details if you can about the specifics of the reduced complexity technique.

Same question as above but for the SU-MIMO and MU-MIMO receiver.
