10.3. MIMO Application
Since the same frequency is used between MIMO1 and MIMO2, operator C, as shown in Figure 10-3, must employ
two special channels in the AU and RU. In order to guarantee coherence between MIMO1 and MIMO2, MIMO1 and
MIMO2 must be in the same AU and RU. The maximum bandwidth per operating band should be less than 60MHz and
the maximum bandwidth of all operators should be less than 200MHz.

10.4. RU Cascade Application
In this scenario, RU1 can connect to the EU or directly to the AU. A maximum of four RUs can cascade when RU1 is
