Practical cross-layer testing of HARQ-induced delay variation on IP/RTP QoS and VoLTE QoE
Abstract As the PHY/MAC-layer IR-HARQ and RLC-layer ARQ error recovery procedures, adopted in LTE, may impose additional delay when their code-block retransmissions occur, the arising question is whether these significantly contribute to IP and consequently RTP packet delays, and finally degrade the...
