摘要：
One of the central features of the high speed downlink packet access (HSDPA) concept is advanced physical layer retransmission scheduling employing soft combining gain, incremental redundancy, and low retransmission delays. This paper studies symbol mapping diversity in combination with power adjustment for HSDPA. If retransmission are requested, the bit-to-symbol mapping and transmission power is changed in every retransmission. Compared to the conventional HARQ schemes, our proposed scheme increases the throughput and decreases the average number of retransmissions significantly and reduce the power consumption in HSDPA.
