“…Passive sensing is widely used for passive localization methods, as in Fig. 11, like received-signal-strength (RSS), time-difference-of-arrivals (TDoA) and angle-of-arrival (AoA) methods [67]. Other use cases of passive sensing include but not limited to air traffic control, weather observation, remote sensing of the environment, aircraft and ship navigation.…”

“…It is noteworthy that since the location of BSs and RISs are fixed, BSs are aware of the surrounding RIS locations. Consequently, by receiving the UE response to the paging message broadcasted from the associated BS and identifying its location (assuming the BS capability of passive localization [56]), the BS can decide which RIS is closer to the UE to split the power between two beams. As a result, the beamwidth of each of these two beams changes, from (2) in the baseline model, into…”

“…It is noteworthy that the RIS needs the direction of the UE, i.e., ϕ, in (12) to generate the matrix Φ. Since the RIS includes a large number of passive elements, it can profit from the angle-of-arrival (AOA) localization technique in [56] to find ϕ when UE identifies itself by broadcasting the response to the paging message from the associated BS. Moreover, assuming the RIS is equipped with received RF chain, as investigated in [13], [26], the RIS can directly obtain the channel state information (CSI) of BS-RIS and RIS-UE paths to achieve the optimal performance.…”

“…There are several techniques to estimate the target position based on different information available from measurements performed on received radio frequency (RF) signals. This means that RF based localization systems may use a multitude of different techniques, which include the angle of arrival (AoA) [4,5], received signal strength (RSS), time of arrival (ToA), time difference of arrival (TDoA) [6][7][8], Doppler difference (DD) [9,10], or hybrid location methods [11]. While some localization techniques usually come at a low cost but a lower accuracy, others require complex synchronization schemes, which usually make them more expensive [12][13][14][15][16].…”
