Downlink resource allocation method and device and related equipment

[0001] Cross-reference to Related Applications

[0002] The present disclosure claims priority to Chinese Patent Application No. 202411311381.5, filed on September 19, 2024, entitled “Downlink resource allocation method and device and related equipment,” the entire contents of which are incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present disclosure relates to the technical field of wireless communication, and more particularly to a downlink resource allocation method, device, electronic device, medium, and computer program product. BACKGROUND

[0004] High-orbit satellites have advantages such as wide coverage and small Doppler frequency shift, and have broad application prospects in NTN scenarios. Due to large coverage area, large number of users, and various types of services, downlink resource allocation of high-orbit satellites is extremely challenging. In 3GPP Rel-18 (the first version of the protocol standard released by the international communication standard organization 3GPP (Third Generation Partnership Project)), downlink performance analysis and optimization assumes that the satellite transmit power of each beam is the same, ignoring the satellite power limit. In 3GPP Rel-19 (the second version of the protocol standard released by the international communication standard organization 3GPP), downlink coverage enhancement research introduces the impact of the skip-beam technology to analyze the downlink coverage performance.

[0005] With the introduction of skip-beam technology and other technologies, the transmit power of each beam of the satellite can be different, which brings the problem of satellite downlink transmit power allocation. At the same time, considering the impact of transmit power on channel capacity and data transmission rate, 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 joint power and time-frequency resource downlink resource allocation method.

[0006] It should be noted that the information disclosed in the above BACKGROUND section is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art.
