摘要:

我们设计了一个自探索的强化学习(RL)框架,基于Q-学习算法,使基站(BS)选择一个合适的调制和编码方案(MCS),最大限度地提高频谱效率,同时保持低块出错率(BLER)。在该框架中,BS基于由用户设备(UE)报告的信道质量指示符(CQI)来选择MCS。利用所选择的MCS进行传输,并且该传输的结果由BS转换成BS用于学习从CQI到MCS的适当映射的奖励。与传统的固定查找表和外环链路自适应相比,所提出的框架在频谱效率和误比特率方面具有更好的性能。

英文摘要:

We design a self-exploratory reinforcement learning (RL) framework, based on the Q-learning algorithm, that enables the base station (BS) to choose a suitable modulation and coding scheme (MCS) that maximizes the spectral efficiency while maintaining a low block error rate (BLER). In this framework, the BS chooses the MCS based on the channel quality indicator (CQI) reported by the user equipment (UE). A transmission is made with the chosen MCS and the results of this transmission are converted by the BS into rewards that the BS uses to learn the suitable mapping from CQI to MCS. Comparing with a conventional fixed look-up table and the outer loop link adaptation, the proposed framework achieves superior performance in terms of spectral efficiency and BLER.
