1. A method, comprising:
receiving, by a first user equipment comprising at least one processor from a second user equipment, a protocol data unit discarding configuration comprising a pre-discarding delay offset;
determining, by the first user equipment, an expected direct transmission time to transmit at least one protocol data unit, directed to a radio network node and corresponding to at least one traffic flow associated with the first user equipment, from the first user equipment to the radio network node to result in a determined direct transmission time;
determining, by the first user equipment, an amount of time that the at least one protocol data unit has been buffered in a memory corresponding to the first user equipment to result in a determined buffered time amount;
based on the determined buffered time amount and a delay budget corresponding to the at least one traffic flow, determining, by the first user equipment, a remaining delay budget corresponding to the at least one protocol data unit;
analyzing, by the first user equipment, the remaining delay budget with respect to the determined direct transmission time and the pre-discarding delay offset to result in an analyzed remaining delay budget;
based on the analyzed remaining delay budget being determined not to exceed the determined direct transmission time and the pre-discarding delay offset, determining, by the first use equipment, to avoid transmitting the at least one protocol data unit to the second user equipment for relay thereby to the radio network node; and
transmitting, by the first user equipment to the radio network node, the at least one protocol data unit.
