Abstract

In this letter, we study the semi-full-duplex (SFD) mode with two users sharing the same resource block, where one user transmits signals for uplink transmissions and the other user receives signals for downlink transmissions. In general, since the downlink signal-to-noise ratio (SNR) is higher than the uplink SNR, we propose an SFD approach that can borrow the downlink rate to balance the downlink and uplink rates based on incremental redundancy. The proposed SFD approach is analyzed to show that a fraction of the downlink rate can be effectively transferred to the uplink rate. In addition, the maximization of the uplink rate is considered.

关于平衡下行链路和上行链路速率的半全双工技术

在这封信中，我们研究了两个用户共享同一资源块的半全双工（SFD）模式，其中一个用户发射信号进行上行链路传输，另一个用户接收信号进行下行链路传输。一般来说，由于下行链路信噪比（SNR）高于上行链路信噪比，我们提出了一种 SFD 方法，可以借用下行链路速率来平衡基于增量冗余的下行链路和上行链路速率。对所提出的 SFD 方法进行分析后发现，下行链路速率的一部分可以有效地转移到上行链路速率上。此外，还考虑了上行链路速率的最大化问题。
