这封信将非正交多址应用于上行链路随机接入系统，其中来自每个用户设备 (UE) 的发射功率在基站处接收为 $L$ 目标（接收）功率之一。更准确地说，如果积压的UE的信道增益大于阈值，它会随机瞄准目标功率之一进行信道反转。然后，BS利用连续的干扰消除来解码接收到的信号。这封信调查了该系统在吞吐量、访问延迟、能源效率和双稳态方面的性能。
This letter applies non-orthogonal multiple access to uplink random access systems, where the transmit power from each user equipment (UE) is received at the base station as one of $L$ target (received) powers. More precisely, if a backlogged UE’s channel gain is greater than a threshold, it randomly aims at one of the target powers with channel inversion. Then, the BS decodes the received signals with successive interference cancellation. This letter investigates the performance of this system in terms of throughput, access delay, energy efficiency, and bistability.
