Description

Background Art

[0002] High-orbit satellites have the advantages of wide coverage and small Doppler frequency shift, and have broad application prospects in NTN scenarios. Due to the large coverage area, large number of users and service types, the downlink resource allocation of high-orbit satellites is extremely challenging. In the downlink performance analysis and optimization of 3GPP Rel-18 (the first version of the protocol standard launched by the international communications standards organization 3GPP (Third Generation Partnership Project)), it is assumed that the transmission power of each satellite beam is the same, and the satellite power limitation is ignored. In the downlink coverage enhancement study of 3GPP Rel-19 (the second version of the protocol standard launched by the international communications standards organization 3GPP), the impact of beam hopping technology is introduced to analyze the downlink coverage performance.

[0003] With the introduction of technologies such as beam hopping, the transmission power of each satellite beam may be different, which brings up the problem of satellite downlink transmission power allocation. At the same time, considering the impact of transmission power on channel capacity and data transmission rate, the joint allocation of power and time-frequency resources is the only way to further improve system capacity. However, there is currently a gap in the downlink resource allocation method of combining power and time-frequency resources.
