In cellular networks, users near the edge of the cell are usually suffering from low signal-to-noise-plus-interference-ratio (SINR) levels as a result from being far away from the base-station (BS). Many factors could lead to huge attenuation of the received signal in the cell-edge area such as path-loss and multipath fading. Increasing the BS transmit power is not always feasible as this could lead to an increased inter-cell-interference (ICI). Hence, the cell-edge problem arises. In this paper, a new scheduling technique has been developed to increase the probability of assigning the available resource blocks (RBs) to the cell-edge users so that their achieved throughput would increase. A performance comparison with state-of-the-art schedulers indicates that our proposed scheduling mechanism leads to a significant improvement in the average throughput for cell-edge users, with negligible performance degradation for cell-center users.

在蜂窝网络中，由于远离基站（BS），靠近小区边缘的用户通常遭受低的信噪比（SINR）水平。许多因素可能导致小区边缘区域中接收信号的巨大衰减，例如路径损耗和多径衰落。增大BS发射功率并不总是可行的，因为这可能导致小区间干扰（ICI）增大。因此，出现了细胞边缘问题。在本文中，已经开发了一种新的调度技术，以增加将可用资源块（RB）分配给小区边缘用户的可能性，从而增加其实现的吞吐量。
