Abstract: A communication device includes a transceiver and a control circuit. The control circuit determines whether to transmit a second MKPDU in advance according to a member identifier of a peer device carried by a received first MKPDU and one or more lists maintained by the communication device. When the member identifier of the peer device is not recorded in the one or more lists, the control circuit determines to transmit the second MKPDU in advance. When the control circuit determines to transmit the second MKPDU in advance, the control circuit generates the second MKPDU, encodes the second MKPDU to generate a frame, and transmits a signal carrying the frame through the transceiver, wherein a time interval between the transmission of the signal and a previous transmission performed by the transceiver is less than a predetermined transmission period.
