Type of weight | Â | How to design |
---|---|---|
Precoding weight | Macro BS | Direct the null space to macro UEs except for the desired UE and eliminate inter-stream interference |
 | Small BS | Align the intra-cluster interference to the strongest interference from macro BS |
Postcoding weight | Macro UE | Eliminate inter-stream interference |
 | Small UE | ZF weight nulls out the aligned interference and MMSE weight mitigate the residual interference |
