Table 4 Design of weights

From: A low-complexity cell clustering algorithm in dense small cell networks

Type of weight

 

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
