| Abstract: | High Speed Uplink Packet Access(HSUPA) is used to improve uplink packet data transfer rate,and to reduce latency in TD-SCDMA.Hybrid Automatic Repeat Request(HARQ) used in HSUPA can enlarge the success rate of the decoder and increase the reliability during the transfer service.The theory of HARQ in TD-SCDMA system are elaborated,a proposal which applied chase combining to HARQ is raised in HSUPA.Under the condition of proper channel model,the uplink performance with different control parameters has been simulated.It is found out that the proposal can increase the system throughput and decrease the BLER effectively and feasibly. |
