Disclosed is a wireless communication device including a communication circuit, a memory and a microprocessor coupled to the memory and the communication circuit. The communication circuit includes a radio frequency circuit and a first communication branch and a second communication branch sharing a frequency band and coupled to the radio frequency circuit. The memory is configured to store a network environment parameter index. The microprocessor is configured to detect a current state of a wireless network in real time based on the network environment parameter index to obtain current wireless network status data; obtain a time division multiplexing parameter according to an optimization goal and the current wireless network status data; and control the first communication branch and the second communication branch by using time division multiplexing according to the time division multiplexing parameter. Thus, spectrum and radio frequency resources can be optimally used.
