摘要：
在高频段运行的通信系统必须使用窄波束来补偿高路径损耗。然而，由于窄波束构成的波束空间体量巨大，在发射机与接收机之间实现波束对准极为耗时。初始波束建立的高时延将对未来6G网络在高频段的部署构成挑战。为解决这一问题，本文提出了一种利用联合通信与感知（JCAS）系统材料感知结果的初始波束建立方法。通过利用环境中反射体预先识别的材料信息，可以预测每个反射体引起的反射损耗（RL）。基站（BS）首先扫描具有低反射损耗的波束方向，并立即建立连接，而无需扫描其余波束方向。通过这种方式，初始波束建立的时延得到显著降低。
英文摘要：
Communication systems operating at high frequency bands must use narrow beams to compensate the high path loss. However, it is incredibly time-consuming to achieve beam alignment between the transmitter and receiver due to the large volume of beam space with narrow beams. The high latency of initial beam establishment will challenge the implementation of future 6G networks at high frequency bands. To tackle this problem, this paper proposes an initial beam establishment method using the material sensing results from joint communications and sensing (JCAS) systems. The reflection loss (RL) induced by each reflector can be predicted by exploiting the pre-identified material information of reflectors in the environment. The base station (BS) first scans the beam directions with low RL and establishes the connection immediately without sweeping the rest of the beam directions. In this way, the latency of initial beam establishment is significantly reduced.
