Integrated Sensing and Communications (ISAC) technology can jointly design radio sensing communication functionalities, which enable 6G Ere to have the ability "see" physical world rather than communication-only. Benefitting from ISAC, vehicular-to-everything (V2X) networks may efficiently complete high-precision traffic environment perception. Furthermore, with assistance of flexibly deployed Unmanned Aerial Vehicles (UAVs), V2X overcome limited range sensors equipped on a vehicle guarantee...

Reasoning over natural language is a long-standing goal for the research community. However, studies have shown that existing models are inadequate in reasoning. To address issue, we present POET, novel reasoning pre-training paradigm. Through with programs and their execution results, POET empowers to harvest knowledge possessed by program executors via data-driven approach. conceptually simple can be instantiated different kinds of executors. In this paper, showcase two instances POET-Math...

In this article, we propose a cell-free network architecture for an unmanned aerial vehicle (UAV) base station (BS), i.e., UBS, incorporating high-altitude platform stations (HAPSs) as central processing units (CPUs). The goal is to guarantee the quality of service (QoS) user equipment (UE), reduce energy consumption, extend communication time, and facilitate rescue operations. millimeter-wave (mmWave) frequency band deployed in access backhaul links satisfy UE QoS requirements high demands....
