    Abstract: A method, apparatus, and computer-readable storage medium are provided for selecting a target cell based on channel impulse response (CIR) measurements, which may include receiving measurement configuration information including a CIR parameter from a first network node and may further include generating one or more measurement reports based on the CIR parameter, the one or more measurement reports including CIR measurements of one or more beams of one or more neighbor cells associated with the first network node and/or second network nodes and transmitting the one or more measurement reports to the first network node.
    The selecting a target cell based on CIR measurements may include transmitting measurement configuration information including a CIR parameter and receiving one or more measurement reports, including CIR measurements of one or more beams of one or more network nodes and selecting a target cell for handover using the measurements.

    Abstract: A source network apparatus (10) which provides access for a user equipment (30) to a communication network transmits (S102) a handover command to the user equipment (30), the handover command indicating a target network apparatus (20) for providing access for the user equipment (30) to the communication network, and a detach condition on when the user equipment (30) is to detach from the source network apparatus (10) after having accessed the target network apparatus (20) (S204) and received user plane data packets from the target network apparatus (20) (S205), wherein the source network apparatus (10) continues exchanging user plane data packets with the user equipment (30) (S101, S103) until the user equipment (30) detaches (S306) from the source network apparatus (10).

    Abstract: An exemplary embodiment provides an apparatus comprising at least one processor and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause said apparatus to determine that a path switch can be initiated during a handover of a user equipment from a first access node to a second access node, determine at least one condition for initiating the path switch, postpone the initiation of the path switch until the at least one condition has been met, and in response to determining that the at least one condition has been met, indicate the initiation of the path switch to the first access node or the second access node.

    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.
