Abstract: Various communication systems may benefit from improved handover. For example, it may be helpful to manage a list candidate cells to which a user equipment may be handed over. A method may include receiving at a user equipment a list of prepared candidate cells from a source cell. The method may also include transmitting the list of prepared candidate cells from the user equipment to a target cell after or during handover from the source cell to the target cell.

Abstract: An embodiment may comprise: transmitting, by a user device in a low activity state a type of the low activity state being according to an anchor access node, a random access message to a network node providing a target cell of a cell reselection. The method may also comprise, in response to receiving a random access response for the random access message from the network node providing the target cell, transmitting, to the network node providing the target cell, a radio connection reactivation request, the reactivation request comprising an indication of an anchor access node of the user device. The method may also comprise, in response to the radio connection reactivation request, receiving a radio connection reactivation message indicating a radio connection reactivation to the anchor access node as a logical link associated with a radio link provided by the target cell of the cell reselection or receiving an inactivation message.

Abstract: An apparatus comprising means for performing: receiving, while connected to a first cell, preparation information for preparing the apparatus for a conditional handover of the apparatus to at least one other cell; receiving, from the first cell, a message, wherein the message causes the apparatus to transition from a connected state to an inactive state; receiving, from the first cell, information of a release condition; when it is determined that the release condition is met, sending a release indication and releasing the preparation information from the apparatus.

Abstract: A PCell for a UE participates in a first phase to add a PSCell to a set of cells including the PCell to be used by the UE for a MCHO, comprising determining that the UE is to participate in the MCHO, and sending indications of at least resources for selected ones of multiple candidate cells toward the UE for use for the MCHO. The PCell participates in a second phase to add the PSCell to the set, comprising determining by the PCell which of the selected multiple cells has been accessed by the UE as the PSCell. The PCell participates in a swap from being the PSCell for the UE to becoming a current PSCell for the UE, wherein the PSCell is swapped from the PSCell to being a current PCell for the UE. The current PSCell participates in a release of a connection to the UE.
