摘要

我们考虑UMTS网络下行链路上的I个传输通道，其速率匹配属性(RMA)值为RMA/sub 1/， RMA/sub 2/，…RMA/sub / I/，在单个编码复合传输信道(CCTrCh)上复用。我们推导了多路复用中每个通道的误码率(ber)的解析表达式。仿真结果表明，该表达式是非常准确的。我们还提供了一个程序，该程序给出了实现指定信噪比的目标ber集所需的RMA值;当不存在可行的RMA值时，该过程也会显示。本文的结果将对希望在保持高频谱效率的同时提供差异化QoS的UMTS服务提供商有用。

Using rate matching attributes for differentiated QoS in UMTS networks

We consider I transport channels on the downlink of an UMTS network, with rate matching attribute (RMA) values RMA/sub 1/, RMA/sub 2/,...RMA/sub I/, that are multiplexed on a single coded composite transport channel (CCTrCh). We derive analytical expressions for the bit error ratios (BERs) seen by each channel in the multiplex. Simulations indicate that the expressions are very accurate. We also provide a procedure that gives the RMA values required to achieve a target set of BERs for a specified signal-to-noise ratio; when no feasible RMA values exist, the procedure indicates that as well. The results of this paper will be of use to UMTS service providers who wish to provide differentiated QoS while maintaining high spectral efficiency.
