论文摘要
Wyner的软手网络被认为是发射机同时发送增强的移动宽带(EMBB)和超可信的低延迟通信(URLLC)服务的消息。由于延迟要求,与EMBB消息相比,URLLC消息在较少的通道使用中传输。为了提高URLLC传输的可靠性,我们提出了一种具有有限的区块长的代码字的编码方案,该方案利用了脏纸编码(DPC)将其从EMBB Transmissions引起的干扰。严格的界限是针对我们方案实现的EMBB和URLLC传输的误差概率的。数值结果表明它们低于标准时间共享。
Wyner's soft-handoff network is considered where transmitters simultaneously send messages of enhanced mobile broadband (eMBB) and ultra-reliable low-latency communication (URLLC) services. Due to the low-latency requirements, the URLLC messages are transmitted over fewer channel uses compared to the eMBB messages. To improve the reliability of the URLLC transmissions, we propose a coding scheme with finite blocklength codewords that exploits dirty-paper coding (DPC) to precancel the interference from eMBB transmissions. Rigorous bounds are derived for the error probabilities of eMBB and URLLC transmissions achieved by our scheme. Numerical results illustrate that they are lower than for standard time-sharing.
