1. A first user equipment (UE), comprising:
a transceiver configured to transmit a first packet that is retrieved from a transmitting buffer to a second UE; and
a processor, coupled to the transceiver, configured to:
reset a transmitting latency timer in response to the transceiver transmitting the first packet to the second UE,
start the transmitting latency timer as a second packet retrieved from the transmitting buffer starts being processed by the first UE for transmission to the second UE,
compare a count of the transmitting latency timer with a transmitting latency threshold during processing of the second packet by the first UE, and
in response to the count of the transmitting latency timer exceeding the transmitting latency threshold,
cease the processing of the second packet by the first UE, and
retrieve a third packet from the transmitting buffer for processing by the first UE.
