Abstract
Systems, methods, apparatuses, and computer program products for reducing handover interruption time using sidelink communication are provided. For example, the handed-over (remote) user equipment may exchange uplink and downlink data with the target cell via the additional or assisting link to another relay user equipment while the remote user equipment performs the random access procedure (random access channel procedure) and may establish its own direct radio link to the target cell.
Claims8
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 to, with the at least one processor, cause the apparatus at least to:
- send, to a target network node, a request for a relay node-aided handover of a user equipment from a first direct link with the apparatus to a second direct link with the target network node;
- and
- receive an acknowledgement associated with the request.

- and
- at least one memory including computer program code,
- wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:
- receive, from a source network node, a request for a relay node-aided handover of a user equipment from a first direct link with the source network node to a second direct link with the apparatus;
- and
- send, to the source network node, a command to perform the relay node-aided handover.
