Abstract

本发明实施例提供了一种无线保真技术的带宽选择方法及AP，在所述方法中，AP获取与站点STA的协商带宽；所述方法包括：AP接收STA的数据传输请求；AP获取STA的传输上限带宽；若传输上限带宽小于协商带宽，AP向STA下发第一MCS；第一MCS小于带宽与MCS的对应关系中与协商带宽对应的MCS，大于等于带宽与MCS的对应关系中与传输上限带宽对应的MCS。可见本发明实施例不仅考虑了AP与STA的协商带宽，还考虑了STA的传输上限带宽，并在一些传输带宽虚高的场景下，根据STA的传输上限带宽降低最终下发的MCS，从而实现了降低下发的传输带宽，因此减少接入点AP和站点STA侧设备的耗电量，增加续航时间。
