Abstract

The invention provides a joint resource allocation method based on Shapley value one-time auction. The joint resource allocation method comprises the following steps: S1, establishing a communicationsystem; S2, calculating signal to interference plus noise ratios of different user sides in the same channel; S3, establishing a user alliance model; S4, initializing the power of the user side; S5, calculating utility values of all user sides of the user alliance model and a utility value after a target user side is removed; S6, calculating a Shapley value of each user side under different channels; S7, calculating a bidding strategy of each user side for different channels according to the Shapley value; S8, distributing the user sides to the channel with the highest bid by utilizing the bidmatrix; and S9, optimizing the power of the user side. According to the joint resource allocation method based on the Shapley value one-time auction, the problem of high interaction complexity between the base station and the user can be effectively solved, and fairness and safety in the channel allocation process are improved.

Description

technical field [0001] The present invention relates to the field of joint resource allocation in a D2D communication system, in particular to a joint resource allocation method based on one auction of Shapley values. Background technique [0002] D2D communication technology is becoming a key technology to improve future network capacity. When D2D users use the same channel as cellular users, it will lead to some problems that need to be solved urgently: effective allocation of channel resources for cellular users; interference elimination between users after channel reuse; high complexity. To solve the above problems, joint channel allocation and power control are needed. Existing solutions generally use complex mathematical processing methods, such as decomposing non-convex resource allocation problems for iterative solutions, obtaining suboptimal power allocation strategies through Lagrangian dual offense methods, using Dinkelbach and branch and bound methods to solve ...
