Resource Allocation for RSMA URLLC Systems A Survey
摘要
Abstract
With the advancement of 5G commercialization,academia is shifting towards the research on 6G communication sys-tems.6G systems not only need to meet the demand for higher data rates but also address the challenges posed by supporting massive users and the connection of billions of IoT devices.As a result,the demand for Ultra-Reliable Low-Latency Communication(URLLC)is increasing.To meet this demand,Rate Splitting Multiple Access(RSMA)as an advanced multiple access scheme is being extensively researched due to its flexible interference management,which improves spectral efficiency and reduces system latency.This paper provides a literature review and summarizes the research status of resource allocation in RSMA URLLC systems from four perspec-tives.These include resource allocation for uplink and downlink in RSMA URLLC system,resource allocation in Reconfigurable Intelli-gent Surface(RIS)-assisted RSMA URLLC system,and resource allocation in RSMA URLLC system combined with emerging technolo-gies such as Unmanned Aerial Vehicle(UAV)and Terahertz.The paper highlights main issues in current research and discusses future research directions for RSMA URLLC systems.关键词
