Quality of Service (QoS) Configuration and Management for UE-to-UE (U2U) Relay based Communication

A user equipment (UE) configured to operate as a first relay UE for facilitating communication between a first UE and a second UE, comprising:

• a processor;
• and
• a memory storing instructions which, when executed by the processor, cause the processor to:
• receive, from the first UE, a first message indicating one or more end-to-end (E2E) quality of service (QoS) parameters between the first UE and the second UE;
• and
• split, based on the first message, the E2E QoS parameters into one or more first QoS parameters for data transmission over a first direct link between the first UE and the first relay UE and one or more second QoS parameters for data transmission over a second link between the first relay UE and the second UE.

A first user equipment (UE) capable of communicating with a second UE via a first relay UE, the UE comprising:

• a processor;
• and
• a memory storing instructions which, when executed by the processor, cause the processor to:
• send, to the first relay UE, a first message indicating one or more end-to-end (E2E) quality of service (QoS) parameters between the first UE and the second UE;
• and
• receive, from the first relay UE, one or more first QoS parameters for data transmission over a first direct link between the first UE and the first relay UE, wherein the one or more first QoS parameters are split by the first relay UE from the one or more E2E QoS parameters indicated by the first message.
