摘要

本文提出了一些处理TDD- td /CDMA场景中通过无线电接口提供服务质量(QoS)的分组传输机制，例如UMTS系统中UTRA TDD提案所考虑的情况。在这种程度上，针对这样的环境提出了基于ISMA和dsa++方法的两种不同的多访问协议，并通过允许减少访问时间的轮询机制加以补充。还考虑了调度算法，以便对传输进行优先级排序，以保证不同服务的特定QoS要求。

Packet transmission strategies to provide quality of service in a TDD-TD/CDMA system

This paper presents some packet transmission mechanisms dealing with the provision of quality of service (QoS) over the radio interface in a TDD-TD/CDMA scenario such as the one considered for the UTRA TDD proposal in the UMTS system. To this extent, two different multiple access protocols are proposed for such an environment, based on the ISMA and DSA++ approaches, and they are complemented by a polling mechanism that allows a reduction in the access time. A scheduling algorithm is also considered in order to prioritise transmissions to guarantee the specific QoS requirements for the different services.
