ABSTRACT
With the increasing number of networked devices, limited spectrum resources will lead to low speed and high latency problems. Compared to 4G networks, 5G networks can achieve higher speeds on limited spectrum. Therefore, the allocation of the idle spectrum resources of 4G network to 5G network will improve the spectrum utilization and can better serve 5G users and 4G users. In order to achieve reasonable resource sharing under the coexistence of 4G and 5G networks, the paper uses the auction game algorithm to flexibly allocate the idle spectrum resources of 4G networks to 5G network. In addition, a penalty mechanism is established to prevent the malicious bidding of the network participating in the game and realize a fair and reasonable game. Experiments show that compared with the advanced spectrum sharing algorithm (bargaining game), the scheme proposed in the paper can achieve higher benefits for 5G networks.
