Abstract
The present disclosure is related to UEs, a network node, and methods for network controlled U2U relay link maintenance. A method at a first UE for performing a U2U communication with a second UE via one or more U2U relay UEs comprises: receiving, from a network node, a message indicating control information for the U2U communication; and communicating with the second UE and/or at least one of the one or more U2U relay UEs for the U2U communication based on at least the indicated control information.

A method at a first User Equipment (UE) for performing a UE-to-UE (U2U) communication with a second UE via one or more U2U relay UEs, the method comprising:
- receiving, from a network node, a message indicating control information for the U2U communication;
- and
- communicating with the second UE and/or at least one of the one or more U2U relay UEs for the U2U communication based on at least the indicated control information.

A method at a UE for facilitating a first UE in performing a U2U communication with a second UE via one or more U2U relay UEs, the method comprising:
- receiving, from the first UE, a discovery message or a link establishment request message;
- and
- communicating with the first UE for the U2U communication based on at least the discovery message or the link establishment request message,
- wherein the discovery message or the link establishment request message indicates at least one of:
- one or more IDs of one or more U2U relay UE candidates;
- one or more priorities associated with the one or more U2U relay UE candidates;
- an indicator indicating whether a U2U relay UE candidate, which is not indicated in the discovery message or the link establishment request message, can be selected or not.

A UE, comprising:
- a processor;
- a memory storing instructions which, when executed by the processor, cause the processor to perform the method of:
- receiving, from a network node, a message indicating control information for the U2U communication;
- and
- communicating with the second UE and/or at least one of the one or more U2U relay UEs for the U2U communication based on at least the indicated control information;
- or
- receiving, from the first UE, a discovery message or a link establishment request message;
- and
- communicating with the first UE for the U2U communication based on at least the discovery message or the link establishment request message,
- wherein the discovery message or the link establishment request message indicates at least one of:
- one or more IDs of one or more U2U relay UE candidates;
- one or more priorities associated with the one or more U2U relay UE candidates;
- an indicator indicating whether a U2U relay UE candidate, which is not indicated in the discovery message or the link establishment request message, can be selected or not.
