本文针对多智能反射面辅助的多接入点多用户系统中的智能反射面选择与主被动联合波束赋形问题，设计不依赖瞬时信道状态信息的智能反射面-用户关联与波束赋形方案。首先基于大尺度衰落参数设计关联方案。之后提出基于1比特反馈的被动波束赋形算法，利用接收信号强度调整反射单元的相位。仿真结果表明用户关联方案对平均信干噪比存在显著影响，收敛后的1比特反馈算法能够接近主被动波束赋形相位对齐时的性能。

Aiming at the problem of intelligent reflecting surface (IRS) association and joint active and passive beamforming in a multi-access point and multi-user system aided by multi-IRSs, we design an association and beamforming scheme that does not rely on instantaneous channel state information. Firstly, the association scheme is designed based on large scale fading parameters. Then a passive beamforming algorithm based on 1-bit feedback is proposed, which adjust the phase of the reflection elements by using the received signal strength. The simulation results show that the user association scheme has a significant impact on the average SINR, and the convergent 1-bit feedback algorithm can approach the performance of active and passive beamforming phase alignment.
