Systems and methods for protocol data unit (PDU) set discard

A transmitter device, comprising:

• a wireless transceiver;
• and
• one or more processors configured to:
• determine, for each of a plurality of protocol data unit (PDU) sets, a discard level, from an ordered set of a plurality of discard levels, assigned to the PDU set, the discard level assigned to the PDU set based on one or more characteristics of traffic corresponding to the PDU set, the one or more characteristics comprising a traffic type of the PDU set;
• determine a congestion status of a network which is to be used to transmit the PDU sets to a receiver device;
• discard a first subset of the plurality of PDU sets, according to a first discard level assigned to the first subset;
• and
• transmit, via the wireless transceiver and the network to the receiver device, a second subset of the plurality of PDU sets having a second discard level.

A non-transitory computer readable medium storing instructions that, when executed by one or more processors of a transmitter device, cause the transmitter device to:

• determine, for each of a plurality of protocol data unit (PDU) sets, a discard level, from an ordered set of a plurality of discard levels, assigned to the PDU set, the discard level assigned to the PDU set based on one or more characteristics of traffic corresponding to the PDU set, the one or more characteristics comprising a traffic type of the PDU set;
• determine a congestion status of a network which is to be used to transmit the PDU sets to a receiver device;
• discard a first subset of the plurality of PDU sets, according to a first discard level assigned to the first subset;
• and
• transmit, via a wireless transceiver and the network to the receiver device, a second subset of the plurality of PDU sets having a second discard level.
