标题： Mobility Management in Integrated Sensing and Communications Networks

摘要： 集成感知与通信(ISAC)网络的性能受到收发器节点、用户设备(UE)以及被感知的被动物体的移动性显著影响。 例如，感知效率会受到感知收发器与物体之间是否存在视距连接的影响；由于移动性，这种状况可能会迅速变化。 此外，UE和物体的移动可能导致通信到感知和感知到通信的干扰动态变化，从而降低网络性能。 在这些情况下，可能需要将感知过程切换到相邻节点。 在本文中，我们提出了ISAC网络中的移动性管理概念。 在此概念中，根据物体和/或收发器节点的移动性、数据流量、收发器的感知或通信覆盖区域以及网络干扰，感知信号的发送和/或接收可能会切换到相邻节点。 同时，ISAC配置和模式——即使用单基地或双基地感知——也会相应更新，以使被感知的物体能够持续地以低开销进行感知。 我们证明，移动性管理可以减少感知中断，并提高ISAC网络的通信和感知效率。 显示英文摘要

摘要： The performance of the integrated sensing and communication (ISAC) networks is considerably affected by the mobility of the transceiver nodes, user equipment devices (UEs) and the passive objects that are sensed. For instance, the sensing efficiency is considerably affected by the presence or absence of a line-of-sight connection between the sensing transceivers and the object; a condition that may change quickly due to mobility. Moreover, the mobility of the UEs and objects may result in dynamically varying communication-to-sensing and sensing-to communication interference, deteriorating the network performance. In such cases, there may be a need to handover the sensing process to neighbor nodes. In this article, we develop the concept of mobility management in ISAC networks. Here, depending on the mobility of objects and/or the transceiver nodes, the data traffic, the sensing or communication coverage area of the transceivers, and the network interference, the transmission and/or the reception of the sensing signals may be handed over to neighbor nodes. Also, the ISAC configuration and modality - that is, using monostatic or bistatic sensing - are updated accordingly, such that the sensed objects can be continuously sensed with low overhead. We show that mobility management reduces the sensing interruption and boosts the communication and sensing efficiency of ISAC networks.
