WebFor both up and downlink a synchronous, single-bit HARQ feedback (ACK/NACK) is sent providing feedback about the success of the previous transmission. The HARQ protocol is adaptive in both uplink and downlink, meaning that the scheduler can decide to use a different resource for a retransmission compared to the previous (re)transmission.
WebIn the synchronous method of operation, the base station knows exactly when to expect the HARQ Ack/Nack indication and no explicit signaling is required: there is a fixed timing relationship between the over-the-air initial transmission (in above example, time=4) and the transmission of HARQ Ack/Nack by the receiver, also over the air (in above example, … Web上行harq上行harq图1是关于上行数据传输的一个示意图除了sr外,不包含pucch.本文主要介绍其中的上行harq处理.图1:上行流程enodeb使用phich来告诉ue是否成功接收pusch,一个上行tb对应一个phich.关于phi
