Abstract
A method in a node is disclosed. The method comprises generating a tag for an associated data packet at a first layer, the generated tag indicating one or more parameters related to transmission of the associated data packet. The method comprises signaling the tag from the first layer to another layer. The method comprises mapping, at the another layer, the associated data packet to a logical channel based on the one or more parameters indicated by the tag, and selecting one or more resources for transmission of the associated data packet based on the mapping of the associated data packet to the logical channel.
Claims34
A method in a node, comprising:
- determining a latency for an associated vehicle-to-anything (V2X) data packet;
- generating a tag for the associated V2X data packet at a first layer, the generated tag indicating one or more parameters related to transmission of the associated data packet, wherein at least one of the one or more parameters comprises a ProSe Per-Packet Priority (PPP) value that is based at least on the latency for the associated data packet;
- signaling the tag from the first layer to another layer;
- mapping, at the another layer, the associated V2X data packet to a logical channel based on the one or more parameters including the PPP value indicated by the tag as well as a traffic type associated with the V2X data packet;
- and
- selecting one or more resources for transmission of the associated data packet based on the mapping of the associated data packet to the logical channel.
A node, comprising:
- one or more processors, the one or more processors configured to:
- determine a latency for an associated vehicle-to-anything (V2X) data packet;
- generate a tag for the associated V2X data packet at a first layer, the generated tag indicating one or more parameters related to transmission of the associated data packet, wherein at least one of the one or more parameters comprises a ProSe Per-Packet Priority (PPP) value that is based at least on the latency for the associated data packet
- generate a tag for an associated vehicle-to-anything (V2X) data packet at a first layer, the generated tag indicating one or more parameters related to transmission of the associated data packet, wherein at least one of the one or more parameters comprises a ProSe Per-Packet Priority (PPP) value;
- signal the tag from the first layer to another layer;
- map, at the another layer, the associated V2X data packet to a logical channel based on the one or more parameters including the PPP value indicated by the tag as well as a traffic type associated with the V2X data packet;
- and
- select one or more resources for transmission of the associated data packet based on the mapping of the associated data packet to the logical channel.
