Regarding TDM eICIC, which of the following descriptions are correct? (Multiple choice)
A . ABS, CRE and CSI-RS technologies are used in the TDM eICIC solution
B . CRE can preferentially switch to the Micro cell, thereby expanding the coverage of the Micro cell.
C . CSI-RS enables more resources in the system to be used for data transmission, improving the performance of Micro cell users in the TDM solution.
D . ABS only sends a very small number of signals or channels, so the interference of such subframes to the neighboring area is significantly lower than that of normal subframes.
Answer: AB
