eMBB和URLLC业务共存场景下的资源分配算法

Resource allocation strategy under the coexistence of eMBB and URLLC

研究增强移动宽带(Enhanced Mobile Broadband,eMBB)和超可靠低时延通信(Ultra-reliable Low-latency Communications,URLLC)的资源分配问题。给URLLC业务提供频谱接入的同时,为了减少对现有eMBB业务的干预,解决URLLC和eMBB业务之间的资源分配问题,在两者组成的无线系统中,提出一种罚函数算法,引入惩罚项将约束最优化问题转换为对一系列无约束最优化问题的求解。仿真实验结果表明,在满足URLLC业务时延和可靠性约束的前提下,提出算法能保持较高的eMBB业务数据传输速率。

This paper studies the resource allocation problems of Enhanced Mobile Broadband(eMBB)and Ultra-reliable Low-latency Communications(URLLC).While providing spectrum access for URLLC services,in order to reduce the intervention of existing eMBB services and solve the problem of resource allocation of the two services,a penalty function algorithm is proposed in the wireless system composed of both eMBB and URLLC services.Simulation results show that under the premise of satisfying the latency and the reliability constraints of URLLC services,the proposed algorithm can maintain a high data transmission rate of eMBB services.
