For efficient streaming over wireless networks, the LTE (Long Term Evolution) system supports the ARQ (Automatic Repeat reQuest) and HARQ (Hybrid Automatic Repeat reQuest) schemes. However, there is no specification about how to use the ARQ and HARQ parameters in order to guarantee the media quality. To cope with this problem, this paper presents a PNDC (Priority and Network-aware Data Control) scheme that can improve the quality of streaming contents in LTE networks. The proposed scheme controls the number of HARQ retransmissions in lower MAC layer based on the priority of SVC (Scalable Video Coding) frames.
