5G Embraces Satellites for 6G Ubiquitous IoT: Basic Models for Integrated Satellite Terrestrial Networks

“…As shown in Fig. 3, in model X, a satellite and a TBS share spectrum resources to communicate with the ST and 2 Focusing on satellite-terrestrial integration, we draw only one satellite to represent a GEO/MEO/LEO satellite. the GMT, respectively.…”

Radio Sensing Using 5G Signals: Concepts, State of the Art, and Challenges

“…The last field is joint radar-communications for 5G. Joint radar-communications has become important in recent years for two reasons: the lack of spectrum for communications and the demand for both radar sensing and data communications in emerging applications [26] - [28]. Radar and communications could co-exist, co-design, or integrate [26].…”

Uplink Sensing Using CSI Ratio in Perceptive Mobile Networks

“…This subsection provides how to obtain one dynamic AoA and delay. Referring to (14), the delay is not explicitly expressed and only exists in zl . From the expression of zl above ( 14), we see that the delay is mixed with TO.…”

“…As discussed in [2], there are three main types of sensing methods using the received communication signals in PMNs. They are named uplink sensing [5]- [9], downlink active sensing [10]- [12], and downlink passive sensing [13], [14]. In view of hardware cost and required facility changes, uplink sensing is the most viable way for realizing radar functions in PMNs.…”
