The CSI report includes one or more CSI quantities determined based on a power control factor for the sub-configuration. The network element determines a spatial pattern based on the received CSI report.

Abstract: Techniques of determining whether to hand over a user equipment to a new base station include requesting power state information from a neighbouring base to see if the power state of the neighbouring BS is sufficient to serve a UE unable to be served by the current BS due to being in a minimum power mode, DL average power control Region #2. For example, when one BS enters DL average power control Region #2, the BS starts to coordinate with its neighbouring BSs to determine whether the neighbouring BSs are not in Region #2 and exchange segments information. The BS coordinates with UEs at a cell-edge to know if switching the UEs at the cell-edge to neighbouring BS(s) can improve their QoS (throughput).
