Abstract
Based on the current HARQ retransmission scheme in the 3GPP LTE uplink, this paper provides an improved scheme of selecting HARQ retransmission redundancy version. The optimized scheme selects the retransmission redundancy version which can maximize the system spectral efficiency, utilizing the combined information of previous retransmission redundancy versions and the channel quality information of the current uplink, and this paper shows the effectiveness of the optimized scheme by link-level simulation.关键词
