标题： Practical IMT and EESS Spectrum Sharing in the 7 to 8 GHz Band

摘要： 7.3 GHz（350 MHz带宽）地球观测卫星（EOS）频段，虽然未受到保护，但用于被动海面温度（P-SST）测量，为天气预报、沿海灾害预防、气候建模和海洋研究提供重要数据。 完整的7 GHz频段（7.125至8.4 GHz），涵盖了这些EOS频率，是潜在可用的中频段最大的连续块，并将在满足预计的无线服务需求方面发挥重要作用。 实时地理围栏频谱共享（RGSS）系统被证明是解决7 GHz频段内P-SST测量与5G或6G网络之间频谱共享的实用且近期的解决方案。 RGSS使IMT网络和EOS辐射计能够共享以7.3 GHz为中心的350 MHz重叠频谱。 它防止对P-SST测量的干扰，同时允许IMT系统在超过99.9%的时间内无限制地访问共享频谱。 通过使用3GPP定义的功能和O-RAN API，可以在不到0.1%的暂停访问时间内防止用户影响。 概念验证RGSS系统的暂停访问时间数据可通过网页或程序化接口提供给学术界、政府和产业研究人员。 显示英文摘要

摘要： The 7.3 GHz (350 MHz bandwidth) Earth Observation Satellite (EOS) band, while not protected, is used for Passive Sea Surface Temperature (P-SST) measurements that provide important data for weather forecasts, coastal disaster prevention, climate modeling, and oceanographic research. The full 7 GHz band (7.125 to 8.4 GHz), which encompasses these EOS frequencies, is the largest contiguous block of potentially available mid-band spectrum and will play a significant role in meeting the anticipated demand for wireless services. A Real Time Geofenced Spectrum Sharing (RGSS) system is shown to be a practical and near term solution to spectrum sharing between P-SST measurements and 5G or 6G networks in the 7GHz band. RGSS enables IMT networks and EOS radiometers to share 350MHz of overlapping spectrum centered at 7.3 GHz. It prevents interference to P-SST measurements while simultaneously allowing IMT systems un-constrained access to the shared spectrum greater than 99.9% of the time. Subscriber impact during the less than 0.1 percent paused access time can be prevented by using 3GPP defined capabilities and O-RAN APIs to move subscribers to other frequencies. Paused access time data from a proof-of-concept RGSS system is available to academic, government, and industry researchers through a web or programmatic interface.
