Asymmetric transmission system and method for time division duplex wireless network

The invention provides an asymmetric transmission system and method for a time division duplex wireless network, and relates to the technical field of wireless communication, and the system comprises two pieces of user equipment which carry out time division duplex communication on the same current working frequency point when the two pieces of user equipment establish initial connection on the time division duplex wireless network; each user equipment comprises a switching module which is used for sending a switching notification by taking the current working frequency point as a sending frequency point when the user equipment needs to switch the receiving frequency point from the current working frequency point to the target frequency point, so as to notify the user equipment at the opposite end to switch to the target frequency point; and the user equipment at the opposite end is used for receiving the switching notification by taking the current working frequency point as a receiving frequency point and s
