阅读说明:本技术 用于5g nr的在运行中交织/速率匹配和解交织/解速率匹配 (On-the-fly interleaving/rate matching and deinterleaving/de-rate matching for 5G NR ) 是由 C·刘 A·里索 L·张 于 2018-11-07 设计创作,主要内容包括:在一方面,一种编码数据以供传输的方法包括:对于要在其上执行交织和速率匹配的经编码数据块,由并行操作的第一交织和速率匹配引擎和第二交织和速率匹配引擎分别在缓冲器的第一起始点和第二起始点处开始从该缓冲器读取该经编码数据块。经编码输出数据包括来自两个引擎的经交织和经速率匹配的数据。在另一方面,一种解码接收到的数据的方法包括:由第一解交织和解速率匹配引擎和第二解交织和解速率匹配引擎分别在对数似然比(LLR)缓冲器的第一起始点和第二起始点处开始读取该LLR缓冲器的数据。经解码输出数据包括两个引擎的经解交织和经解速率匹配的数据。(In one aspect, a method of encoding data for transmission includes: for an encoded data block on which interleaving and rate matching are to be performed, the encoded data block is read from a buffer by first and second interleaving and rate matching engines operating in parallel, starting at first and second starting points, respectively, of the buffer. The encoded output data includes interleaved and rate-matched data from both engines. In another aspect, a method of decoding received data includes: reading data of a log-likelihood ratio (LLR) buffer is started at a first start point and a second start point of the LLR buffer by a first deinterleaving and de-rate matching engine and a second deinterleaving and de-rate matching engine, respectively. The decoded output data includes the deinterleaved and de-rate matched data of both engines.)
