The authors consider in this paper downlink scheduling at the Medium Access Control Layer (MAC) layer for delay sensitive traffic in wireless systems based on Orthogonal Frequency Division Multiple Access (OFDMA). They refer in particular to next generation wireless systems such as 3GPP-LTE. They propose an Opportunistic Packet Loss Fair (OPLF) scheduling algorithm based on calculating a simple dynamic priority function which depends on the Head Of Line (HOL) packet delay, the Packet Loss Rate (PLR) and the achievable instantaneous downlink rate of each user.
