Leveraging A Variety of Anchors in Cellular Network for Ubiquitous Sensing

15:00-16:00 May 9 (Thursday) , Z311

Integrated sensing and communication (ISAC) has recently attracted tremendous attention from both academia and industry, being envisioned as a key part of the standards for the sixth-generation (6G) cellular network. A key challenge of 6G-oriented ISAC lies in how to perform ubiquitous sensing based on the communication signals and devices. Previous works have made great progresses on studying the signal waveform design that leads to optimal communication-sensing performance tradeoff. In this talk, we aim to focus on issues arising from the exploitation of the communication devices for sensing in 6G network. Particularly, we will discuss about how to leverage various nodes available in the cellular network, including base stations, reconfigurable intelligent surfaces, and user equipments, as anchors to perform ubiquitous sensing. The advantages and disadvantages of each type of anchors will be discussed, and the possible solutions to overcome these disadvantages will be outlined.
