Abstract: An apparatus comprising: at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: operate the apparatus in a dual connectivity mode, wherein the apparatus is in communication with a master cell group comprising a primary cell and at least one secondary cell and the apparatus is in communication with a secondary cell group comprising a primary cell and at least one secondary cell; detect a radio link failure between the apparatus and the primary cell of the secondary cell group; provide information based on the radio link failure to the primary cell of the master cell group, the information being that the radio link failure occurred on the secondary cell group while waiting for a prepared conditional cell change from the primary cell of the secondary cell group to be fulfilled.

Abstract: A network node comprising at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform: transmitting a request to a plurality of nodes to prepare one or more cell candidates; receiving an indication from at least one of the plurality of nodes indicating a capacity to prepare one or more further cell candidates; and transmitting, to one or more of the at least one of the plurality of nodes, a further request to prepare at least one further cell candidate.

Abstract: A method may include receiving a request for conditional handover from a source node. The method may also include sending a conditional handover request acknowledgment message in response to the request. The method may further include sending a conditional handover cancellation message to a source node. The conditional cancellation message may include a genuine cancellation or a modification-related cancellation. Further, the method may include receiving a response message from the source node in response to the conditional handover cancellation message. In addition, the method may include deciding to keep or release user equipment context based on the response message.

Abstract: For a UE in idle mode and camped on a current cell, in response to receiving a paging message indicating the UE should perform a process to select a cell for camping on for idle mode, the following are performed: performing the process to select one of a plurality of cells for camping on for idle mode; and performing operations to camp on the selected cell. The following are performed as part of a continuous load-balancing process for idle-mode load balancing for a cell: determining whether the cell is congested for UEs camping on the cell while in idle mode; and in response to a determination the cell is congested, sending a paging message to idle-mode UE(s) camped on the cell, wherein the paging message is configured to cause the idle-mode UE(s) to start a process to select a cell for camping on for idle mode.
