Quality of service support for layer 2 based device-to-device relay

A method for wireless communication, comprising:

• communicating via a relay wireless communication link, the communicating comprising communications using a plurality of bearers;
• receiving, on the relay wireless communication link, a packet comprising a layer 2 header processed by a relay wireless device that is configured to convey an indication of a quality of service (QoS) parameter set;
• identifying, based at least in part on the QoS parameter set, a first bearer used to convey the packet on the relay wireless communication link, the first bearer being associated with the QoS parameter set;
• and
• identifying the first bearer based at least in part on the QoS parameter set indication and an allocation and retention policy (ARP) indicator of the first bearer.

A method for wireless communication, comprising:

• communicating via a relay wireless communication link, the communicating comprising communications using a plurality of bearers;
• identifying a bearer mapping configuration associated with the relay wireless communication link;
• identifying a packet for transmission on the relay wireless communication link belonging to a first bearer, the first bearer being associated with a quality of service (QoS) parameter set;
• configuring, according to the bearer mapping configuration, a layer 2 header of the packet that is processed by a relay wireless device to include an identifier, the identifier conveying information associated with the first bearer;
• configuring the layer 2 header to include the indication of the QoS parameter set and an allocation and retention policy (ARP) indicator of the first bearer;
• and
• transmitting the packet comprising the layer 2 header on the relay wireless communication link.
