In this paper, a work mechanism of CQI for TD-SCDMA and a adaptive on-demand/ NACK channel quality feedback scheme is introduced.

本文介绍了TD-SCDMA模式下HSDPA中CQI的工作机制和一种基于NACK的自适应信道质量反馈技术。

Candidate cooperative nodes uses NACK frame to select appropriate cooperative nodes by selection algorithms, and further calculate the send rate needed.

候选协作节点利用NACK报文通过协作节点选择算法竞争选取合适的协作节点，并在此基础上计算出所需发送速率。

Instead, if it is missing just one message in a million, it can Nack just the missing message.

其实，如果在一百万消息中有一条被丢失，那么RMD可以仅对丢失的消息要求Nack。
