针对可重构智能表面(RIS)辅助的异构网络切片,提出了联合资源分配和相移优化的资源优化方法。对于异构网络中的不同业务,构建了不同目标的联合优化问题。针对增强型移动宽带(eMBB)业务,基于交替优化算法,联合优化资源块分配、功率分配和RIS相移矩阵,使eMBB用户的遍历总容量最大化。针对超可靠低时延通信(URLLC)业务,以最大化 URLLC 数据包接收率和最小化 eMBB 速率损失为目标,提出基于预配置RIS的启发式URLLC分配算法。仿真结果表明,与未部署RIS时95.95%的URLLC数据包接收率相比,所提算法仅使用80个RIS,实现了约99.99%的URLLC数据包接收率,同时提高了约86.24%的eMBB速率总和。
For reconfigurable intelligent surface (RIS)-assisted heterogeneous network slicing
a resource optimization method with joint resource allocation and phase shift optimization was proposed.A joint optimization problem with different objectives was constructed for different services in heterogeneous networks.For enhanced mobile broadband (eMBB) services
the resource block allocation
power allocation and RIS phase shift matrix were jointly optimized based on the alternating optimization algorithm to maximize the total traversal capacity of eMBB users.For ultra-reliable low-latency communication (URLLC) services
a pre-configured RIS-based heuristic URLLC allocation algorithm was proposed with the objectives of maximizing the URLLC packet reception rate and minimizing the amount of eMBB rate loss.Simulation results demonstrate that the proposed algorithm achieves about 99.99% URLLC packet reception rate using only 80 RISs compared to 95.95% URLLC packet reception rate when no RISs are deployed
while the total eMBB rate is increased by 86.24%.
