As previously mentioned, the network may indicate the PDSCH characteristics of up to eight dominant interferers. This is particularly important as changes in dominant interference may happen with a faster rate compared to the RRC signalling rate. Providing network assistance for multiple potential dominant interferers may be seen as a proactive signalling approach. As the network does not have the dynamic information on the dominant interferer seen by NAICS UE at a particular time, the network assistance consists of interference characteristics as point- specific information, not UE specific. Note that the signalling request is based on the indicated dominant interferers by the UE. The UE would utilize the IC if the network assistance is available at that point in time, otherwise a fallback mode to no IC should be utilized by the UE. Proactive network assistance would facilitate PDSCH IC also in the situation when there is a change in the point of origin in time of the dominant interferer. Table 11.1 shows the NAICS system performance in a homogeneous deployment. The technology is applicable in heterogeneous networks as well. In this particular example, bursty traffic has been used while the baseline is SU MIMO operation. In these simulations, TM9 interference is cancelled by NAICS UEs also configured in TM9; however, NAICS UEs Table 11.1 NAICS system performance in homogeneous scenarios Rel-11 baseline, SU-MIMO, bursty traffic Cell edge Average NAICS SLIC receiver (Rel-11 IRC CQI) +11.7% +7.4% LTE Macro Cell Evolution have the ability to cancel a vast amount of TMs such as TM1, 2, 3, 4, 6, 8 and 9.
