Abstract: In wireless communication, a device may handover between cells of network access for inter-cell mobility without interruptions. In a Dual Active Protocol Stack (DAPS) handover, the user equipment (UE) maintains simultaneous connection with the source node and target node until releasing the source cell after successful access to the target cell. The source node may generate the power coordination and/or resource coordination parameters or configurations that are transmitted to the target node during the handover. When there is a centralized unit (CU) split from a distributed unit (DU), the CU or DU may generate and/or transmit the parameters/configurations to the peer node.
