由于5G蜂窝网络中更高的无线传输速率，在智能手机中产生更高的计算开销，这可能导致无线传输速率受到无线终端的计算能力的限制。在这种情况下，智能手机在5G蜂窝网络中保持稳定的无线通信是否有最高接收速率？本文的主要目的是研究智能手机的最大接收速率及其对5G蜂窝网络的影响。基于Landauer原理和智能手机表面的安全温度边界，提出了5G蜂窝网络中智能手机的最大接收速率。此外，已经研究了智能手机的最大接收速率对链路自适应传输方案的影响。数值分析表明，智能手机的最大接收速率并不总是能赶上未来5G蜂窝网络的下行速率。因此，未来5G蜂窝网络的链路自适应传输方案必须考虑智能手机的最大接收速率。
Due to the higher wireless transmission rates in the 5G cellular networks, higher computation overhead is incurred in smartphones, which can cause the wireless transmission rates to be limited by the computation capability of wireless terminals. In this case, is there a maximum receiving rate for smartphones to maintain stable wireless communications in 5G cellular networks? The main objective of this article is to investigate the maximum receiving rate of smartphones and its influence on 5G cellular networks. Based on Landauer's principle and the safe temperature bound on the smartphone surface, a maximum receiving rate of the smartphone is proposed for 5G cellular networks. Moreover, the impact of the maximum receiving rate of smartphones on the link adaptive transmission schemes has been investigated. Numerical analyses imply that the maximum receiving rate of smartphones cannot always catch up with the downlink rates of future 5G cellular networks. Therefore, the link adaptive transmission scheme for future 5G cellular networks has to take the maximum receiving rate of smartphones into account.
