Abstract

The embodiment of the invention provides a resource allocation method, and relates to the technical field of communication. By adoption of the resource allocation method, the maximum throughput gain is realized, and the maximum rate gain of D2D users and the minimum rate loss of cellular users are realized at the same time. The method comprises the following steps: obtaining a D2D user set which is about to access a cellular cell and a cellular user set in the cellular cell; carrying out power allocation on the D2D user set and the cellular user set; and determining cell resources respectively corresponding to the D2D user set and the cellular user set according to a power allocation result. The resource allocation method provided by the embodiment of the invention is suitable for use in a resource allocation process.

Description

【Technical field】 [0001] The present invention relates to the field of communication technologies, in particular to a resource allocation method and device. 【Background technique】 [0002] The D2D (Device-to-Device, terminal direct connection) communication mode can adapt to the application of high-speed data transmission, and can meet people's demand for high-speed data transmission. Under the control of the cellular system, D2D users reuse the frequency resources of the cell, which can greatly improve the spectrum efficiency. The current research direction is to maximize the performance indicators of communication systems, such as throughput, power and energy consumption. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] In the current process of maximizing the performance index of the communication system, D2D users will be required to reuse cellular user resources, and...
