    • In a flexible layer one (403) of a GERAN transmitter device, a TFCI, which indicates a particular combination of cyclic redundancy check, channel coding and rate matching, is generated by a TFCI generating process (412) using information from the medium access control layer. The TFCI is coded by a coding process (413), and inserted into the data stream by a TFCI insertion process (414). Each code has more bits than the corresponding TFCI, and identifies uniquely the TFCI. The coded TFCI is spread across the pre-interleaved block with portions placed in fixed positions in each burst. Interleaving is then performed by an interleaver (411). The coded TFCI used with a half-rate channel is the central segment of the coded TFCI used in the corresponding full-rate channel. The additional loss is so small as to be insignificant, but the FER performance is significantly improved, compared to using the full-rate codes, as a result of the increased payload of the content data bits. In half-rate mode, the amount of coded TFCI data gives rise to a ratio of the performance of the coding of the transport format combination data to the performance of the coded content data which is at a similar level to the ratio in the full-rate mode.
    • 在GERAN发射机设备的灵活层(403)中,通过使用来自媒体访问控制的信息的TFCI生成处理(412)生成指示循环冗余校验,信道编码和速率匹配的特定组合的TFCI 层。 TFCI由编码处理(413)编码,并通过TFCI插入处理(414)插入到数据流中。 每个代码具有比相应的TFCI多的位,并且唯一地识别TFCI。 经编码的TFCI分布在预先交错的块上,每个突发中的部分被置于固定位置。 然后由交织器(411)执行交织。 与半速率信道一起使用的编码TFCI是相应全速率信道中使用的编码TFCI的中心段。 由于内容数据位的有效负载增加,与使用全速率代码相比,额外的损失非常小,因此无法显着提高FER性能。 在半速率模式中,编码的TFCI数据的量导致传输格式组合数据的编码的性能与编码的内容数据的性能的比率与编码的内容数据的性能相当, 速率模式。
