Description

Method for determining and indicating beam hopping resources, device and storage medium Technical Field The present application relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for determining and indicating a beam hopping resource, and a storage medium. Background The conventional multi-beam satellite distributes bandwidth and power uniformly to each spot beam, but the resource utilization rate of the satellite system is not high due to the non-uniform distribution and demand of ground services, so that the actual communication capacity is greatly reduced. In order to improve the resource utilization efficiency of satellite beams and the transmission capacity of satellite communication, a beam hopping technology is provided on the basis of traditional multi-beams. Currently 3GPP Non-terrestrial networks (Non-TERRESTRIAL NETWORKS, NTN) support transparent forwarding mode and regeneration mode. In the transparent forwarding mode, the base station is on the ground, and the satellite load is only responsible for the functions of radio frequency filtering, frequency conversion and amplification. In the regeneration mode, the satellite payload has functions of radio frequency filtering, frequency conversion and amplification, demodulation/decoding, switching and/or routing, encoding/modulation, etc., which corresponds to functions of all or part of the base station on the satellite platform. Currently, NTN studies focus mainly on the mode of operation of mobile spot beams in transparent forwarding. Due to the reasons of limited power and large coverage of a satellite communication system, the traditional spot beam scheme has low resource utilization rate and low system communication capacity. Therefore, to improve flexibility and coverage of NTN scene networking, on-board processing and beam-hopping techniques are very important. The working mode of the beam hopping is to cover different wave positions in a time sharing way, so the time and coverage range of the beam hopping service are dynamically variable, which causes great problems for the beam access and data transmission of the terminal. Currently, the related art does not support the beam hopping technology, and it is difficult to implement beam hopping indication.
