Problems solved by technology

However, these methods do not reduce the interference between D2D users and cellular users at the same time. These methods are often only considered from the perspective of cellular user performance or D2D system user performance, and do not consider the fairness sacrifice brought by the algorithm.

Embodiment 1

[0050] In order to verify the performance of the proposed resource allocation algorithm based on graph theory, construct such as Figure 4 The computer simulation platform shown in this paper compares the performance difference between the algorithm proposed in this paper and the traditional greedy resource allocation method in terms of system throughput and user rate through Monte Carlo simulation. The specific parameter configuration is shown in Table 1.

Abstract

The invention discloses a spectrum resource allocation method, which belongs to the technical field of wireless network resource allocation. The method is a spectrum resource allocation method applied to the coexistence of heterogeneous communication modes in the downlink direction of a mobile communication network, and includes the following steps: (1) cellular users (2) Use the Hungarian algorithm for user pairing; (3) D2D user-side spectrum resource allocation; the above three steps are repeated in turn until all spectrum resources are allocated; and through the simulation results, it can be seen that compared with traditional frequency allocation method, the algorithm proposed in the present invention brings a certain gain to the system spectrum efficiency.

Description

technical field [0001] The invention relates to a frequency spectrum resource allocation method, which belongs to the technical field of wireless network resource allocation. Background technique [0002] With the rapid development of mobile Internet services and the popularization of smart phones, people's requirements for data transmission capabilities continue to increase. However, limited resources cannot meet this requirement. Therefore, in order to improve resource utilization, overall network performance and user experience, a device-to-device (D2D) technology based on point-to-point direct communication is applied to the fifth generation communication system. On the one hand, the use of D2D technology can reduce the load of traditional base stations and provide users with high-speed data services in some application scenarios. On the other hand, it can use the relay communication capabilities of terminals to solve the coverage black hole problem of the system to a ce...
