1. A wireless communication device, comprising:
a transmitter circuit;
a control circuit, arranged to set a request to send (RTS) frame, and control the transmitter circuit to transmit the RTS frame via at least one channel excluding a preamble punctured channel, wherein said at least one channel comprises all channels of a preamble punctured physical layer protocol data unit (PPDU) that are not preamble punctured; and
a receiver circuit, arranged to receive a clear to send (CTS) frame sent in response to the RTS frame, where the CTS frame has a punctured resource unit (RU) allocation, and is transmitted via channels that are the same as all channels of the preamble punctured PPDU that are not preamble punctured.
