Description

TECHNICAL FIELD The present invention relates to measurement feedback configuration technologies for terminals, and more particularly, to a measurement feedback method, a network device, and a terminal. BACKGROUND For satellite communication systems, due to a long distance between a satellite and a terminal and a wide coverage of the satellite, the link quality between different terminals and the service satellite has strong consistency. In this case, if a measurement feedback mechanism of a cellular communication is still used, many terminals will make a lot of useless measurements, waste a lot of communication resources and consume more power, which is not beneficial to improvement of the communication quality. WO2019170866A1 provides a method of operating a user equipment (UE) device in communication with a non-terrestrial communication system including a plurality of transmission points, the method including in the UE device triggering a transmission of a measurement report dependent on a measurement by the UE device of a received signal parameter of a signal received from a transmission point of the system and a comparison of the measured parameter with a threshold, the threshold varying according to a predetermined function dependent on an expected position of the UE device with respect to the transmission point. WO2020091527A1 relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure provides a signal transmission method, apparatus, electronic device and computer readable storage medium. SUMMARY The invention is set out in the appended set of claims.
