AI 中文摘要
基于上行链路正交频分多址的随机接入（UORA）是新一代WiFi系统中支持上行链路多用户接入的新信道接入机制。任何关联站（STA）都可以使用UORA以竞争方式向接入点（AP）发送请求或数据。本文对模拟研究进行了全面评估，该研究调查了UORA中结合捕获效应的两种功率控制策略，并观察了STA空间分布的公平性问题。结果表明，功率控制策略可以提高UORA的接入成功概率、延迟、资源利用率和功率效率。
英文摘要
Uplink OFDMA-based random access (UORA) is a new channel access mechanism that supports uplink multiuser access in the new generation WiFi systems. Any associated stations (STAs) can use UORA to send their requests or data to the access point (AP) in a contention manner. In this paper, we provide a comprehensive evaluation for simulation study that investigates two power control strategies combined with capture effect in UORA and observes the fairness issue for spatial distribution of STAs. The results demonstrate that power control strategies can improve the performance of access success probability, delay, resource utilization, and power efficiency of UORA.
