Abstract

The embodiment of the present disclosure relates to a resource allocation method for NOMA and D2D integrated communication, which includes: obtaining channel allocation information of individual CUE users in the initial user group, channel allocation information of D2D users, and D2D user power; according to the channel allocation of CUE users Allocation information, channel allocation information of D2D users and D2D user power are optimized and calculated to obtain CUE user power allocation information; individual fitness values ​​are obtained based on the channel allocation information of CUE and D2D users and CUE user power allocation information; from the initial user group Randomly select three individuals, calculate the fitness values ​​​​of the three individuals, and generate new individuals; compare the fitness values ​​​​of the new individuals with those in the initial user group to optimize the remaining individuals. This disclosure proposes a joint resource allocation algorithm based on differential evolution to effectively improve network performance and maximize network resource utilization efficiency.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a resource allocation method for NOMA and D2D converged communication. Background technique [0002] The rapid development of mobile communication networks and the rapid increase of mobile communication services have brought enormous challenges to existing wireless resources. In order to improve spectrum resource utilization, Non-Orthogonal Multiple Access (NOMA) technology allows multiple users to occupy the same channel in a power multiplexing manner. At the same time, Device-to-Device (Device-to-Device Device (D2D for short) technology allows short-distance users to communicate directly without going through the transfer of base station nodes, thereby reducing the communication pressure of the base station and improving resource utilization efficiency. [0003] In order to maximize the utilization of spectrum resources, D2D communication generally needs ...
