摘要
Abstract
In LTE(3G Long Term Evolution), larger TB(Transport Block) occupies more time-frequency resources and is prone to error so as to a waste of resources. In view of this case, a novel transmission scheme of Hybrid Automatic Retransmission Request(HARQ)is proposed. The new transmission scheme takes segmentation based on the TB size in the HARQ entity instead of the segment function of physical layer. Then multiple segment data blocks can be transported parallelly in a single process. If the data are needed to be retransmitted, the transmitter only transports the error segmentation data. Simulation results show that the proposed new transmission scheme is obviously better than the traditional scheme in regard to system throughput and the average number of transmissions.关键词
