CS principle LTE Macro Cell Evolution needs to identify and estimate the PDSCH characteristics of the dominant interfering PDSCH coming from neighbouring cells. This is not an easy task due to the system dynamics and design flexibility. Due to the UE limitations in terms of complexity, the NAICS technology can handle the cancellation of only one dominant interferer while also only a maximum of three layers may be processed. This means that NAICS processing may happen in several combinations of desired streams and interfering streams; more specifically, NAICS processing is expected in the following configurations: one desired layer and one dominant interfering layer; one desired stream and two dominant interfering streams originating from the same interfering UE; and two desired layers and one dominant interfering layer. Before we address the NAICS-specific operation, it is worth giving a brief description on candidate receiver structures which qualify for the task of interference cancellation and suppression. The main differentiator between these receiver structures is related to the degree of knowledge required by the receiver with respect to the signal which needs to be suppressed/ cancelled. We need to make a clear differentiation between the receiver structure as such and the mechanism used by the terminal in order to blindly estimate the parametrization of the interfering signal. In the following, we will address the receiver structures while later we discuss aspects related to the interference characteristics. The UE receiver structures may be classified as linear interference suppression receivers and non-linear interference cancellation receivers. In order to achieve advanced interference suppression/cancellation, any such receiver structure needs to identify the dominant interferer to a certain extent. Hence, we can consider the receivers herein as interference-aware receivers. The linear receivers are based on the principle of enhanced linear minimum mean squared error interference rejection combining (
