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.

在半全双工上,用于平衡下行链路和上行链路速率



在本文中,我们研究了半全双工 (SFD) 模式,其中两个用户共享同一个资源块,其中一个用户传输上行链路传输信号,另一个用户接收下行链路传输信号。一般来说,由于下行信噪比 (SNR) 高于上行链路 SNR,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 方法进行了分析,表明下行速率的一小部分可以有效地转移到上行速率。此外,还考虑了上行链路速率的最大化。
