Backhaul. A precondition in JT CoMP is the exchange of CSI between collaborating network nodes, which are cooperating eNBs or a central unit (CU). The nodes are connected via a gateway to the core network. Based on CSI and user data of all cooperatively served UEs, spatial signal processing (SSP) is performed by precoding the data signals in order to avoid interference, as described in the previous section. Based on the locality of the SSP, centralized and distributed setups can be distinguished, as shown at the left and at the right of Figure 5.13
