Device association method

A device association method is provided. A method according to some embodiments includes reporting, by a beamforming receiver, an encryption capability indicator to a beamformer, where the encryption capability indicator indicates a capability of the beamforming receiver to encrypt a feedback frame. The method may also include, in response to the beamformer receiving an indication that the beamforming recipient is capable of encrypting the feedback frame, receiving, by the beamforming recipient, an advertisement frame from the beamformer, and then transmitting, by the beamforming recipient, the encrypted feedback frame. 提供了装置关联方法。根据一些实施例的方法包括：由波束成形接收方向波束成形器报告加密能力指示符，其中，所述加密能力指示符指示所述波束成形接收方对反馈帧进行加密的能力。所述方法还可包括：响应于所述波束成形器接收到关于所述波束成形接收方能够对所述反馈帧进行加密的指示，由所述波束成形接收方从所述波束成形器接收通告帧，然后由所述波束成形接收方发送加密的反馈帧。
