A wireless transceiver device includes a communication module and a processor. The communication module is used for receiving and demodulating a radio frequency signal from a wireless signal transmitting-receiving end into a first data frame. The processor is coupled to the communication module and used for performing the following operations: obtaining a first modulation order from the first data frame; determining a second modulation order corresponding to a second data frame that is to be transmitted by the wireless transceiver device; and determining a transmission mode from a frame transmission rate table according to a smaller one of the first modulation order and the second modulation order for the wireless transceiver device to send a response frame to the wireless signal transmitting-receiving end in response to the first data frame.

Wireless transceiver device, wireless communication system and wireless transmission rate control method

A wireless communication device for a transmission end of a wireless communication system is provided. The wireless communication device includes a wireless analog transmission unit, for transmitting a data packet on a data transmission channel; and a packet generating unit, for generating the data packet and at least one protection packet; wherein before transmitting the data packet on the data transmission channel, the wireless communication device transmits the at least one protection packet on at least one adjacent channel of the data transmission channel to indicate to at least one user of the at least one adjacent channel to stop using the at least one adjacent channel before transmission of the data packet is completed, and at least one frequency band of the at least one adjacent channel overlaps a frequency band of the data transmission channel.
