外文摘要：Orthogonal time frequency space (OTFS) modulation is viewed as a promising technique to realizing integrated sensing and communications (ISAC) as the physical parameters can be directly extracted through the delay Doppler domain channel。 In this paper， we investigate the sensing ability of OTFS signals to assist vehicle-to-infrastructure (V2I) communications。 Specifically， we propose a new scheme to alternatively sense wide beam and narrow beam to vehicles， where the wide beam is adopted to estimate and refine the sensed parameters with multiple echoes。 Then， the RSU can formulate the narrow beam according to the predicted parameters for effective communication。 Finally， we show the performance of our method， which attains effective communications。
