翻译：Notably, the utility functions here do not consider the resource sharing fraction applied in Ye et al. [5]. Instead, we directly use the achievable rate in the utility function. The reasons for this approach are two-fold. First, a UE device can accurately estimate the channel state information (CSI) between itself and a certain BS, but it may not effectively determine the number of devices that are currently being serviced by the BS. Second, the resource allocation strategies adopted by BSs are almost unknown to each UE. Therefore, we remove the resource sharing fraction from the utility function and achieve load balancing based on the access price and the mutual game among BSs.

值得注意的是，这里的效用函数并没有考虑Ye等人在[5]中使用的资源共享比例。相反，我们直接在效用函数中使用可达速率。采取这种方法的原因有两个。首先，用户设备可以准确估计自身与某个基站之间的信道状态信息(CSI)，但可能无法有效确定当前由基站服务的设备数量。其次，基站采用的资源分配策略对每个用户设备几乎是未知的。因此，我们从效用函数中去除了资源共享比例，并基于接入价格和基站之间的博弈实现负载均衡。
