Abstract
A relay UE (502) having a PC5 link with a remote UE (501) creates a modified downlink (DL) packet by adding one or more reflective quality-of-service (QoS) indicators to the DL packet and transmits the modified DL packet on the PC5 link in a PC5 QoS flow to the remote UE. The remote UE receives the modified DL packet, uses the one or more reflective QoS indicators to derive one or more mapping relations, and applies the one or more derived mapping relations to map an uplink (UL) packet to the QoS flow and transmit the UL packet on the PC5 link. The relay UE receives the UL packet and transmits the UL packet to a network node (504) or a second relay UE.
Claims16
A method performed by a relay user equipment (UE) that has a PC5 link with a remote UE, the method comprising:
- receiving a downlink (DL) packet;
- adding one or more reflective quality-of-service (QoS) indicators to the DL packet, thereby creating a modified DL packet containing one or more reflective QoS indicators;
- and
- transmitting the modified DL packet containing the one or more reflective QoS indicators on the PC5 link in a PC5 QoS flow to the remote UE, wherein
- the method further comprises:
- receiving a UE capability indicator transmitted by the remote UE, wherein the UE capability indicator indicates whether the remote UE supports reflective QoS on a PC5 link;
- using the received UE capability indicator to determine that the remote UE supports reflective QoS on a PC5 link;
- transmitting the UE capability indicator that indicates whether the remote UE supports reflective QoS on a PC5 link to a network node or a second relay UE;
- transmitting a UE capability indicator that indicates whether the relay UE supports reflective QoS on a PC5 link to a network node or a second relay UE;
- and
- receiving service information transmitted by the remote UE, wherein the service information indicates whether the remote UE will adopt or allow reflective QoS for each of one or more services, and
- the relay UE adds the one or more reflective QoS indicators to the DL packet in response to determining that the remote UE supports reflective QoS on a PC5 link.
A relay user equipment (UE) comprising:
- processing circuitry;
- and
- a memory, said memory containing instructions executable by said processing circuitry, whereby the relay UE is operative to:
- receive a downlink (DL) packet;
- add one or more reflective quality-of-service (QoS) indicators to the DL packet, thereby creating a modified DL packet containing one or more reflective QoS indicators;
- and
- transmit the modified DL packet containing the one or more reflective QoS indicators on a PC5 link in a PC5 QoS flow to a remote UE, wherein
- the UE is further operative to:
- receive a UE capability indicator transmitted by the remote UE, wherein the UE capability indicator indicates whether the remote UE supports reflective QoS on a PC5 link;
- use the received UE capability indicator to determine that the remote UE supports reflective QoS on a PC5 link;
- add the one or more reflective QoS indicators to the DL packet in response to determining that the remote UE supports reflective QoS on a PC5 link;
- transmit the UE capability indicator that indicates whether the remote UE supports reflective QoS on a PC5 link to a network node or a second relay UE;
- transmit a UE capability indicator that indicates whether the relay UE supports reflective QoS on a PC5 link to a network node or a second relay UE;
- and
- receive service information transmitted by the remote UE, wherein the service information indicates whether the remote UE will adopt or allow reflective QoS for each of one or more services.
