METHOD, SYSTEM, AND DEVICE FOR TIME-DIVISION DUPLEX COMMUNICATION

摘要

The present application relates to the technical field of wireless communication, and relates particularly to a method, a system, and a device for time division duplex communication, for use in solving the problem in the prior art of the inability to meet the needs of a service in a cell due to the division of an uplink subframe and a downlink subframe remaining fixed after being confirmed. The method of the present application comprises: a network side confirming the subframes in a wireless frame, which comprises a variable subframe, a downlink constant subframe, and an uplink constant subframe, wherein the downlink constant subframe is a subframe having the downlink direction as the transmission direction, which remains constant, and is a downlink pilot time slot in a special subframe, the uplink constant subframe is a subframe having the uplink direction as the transmission direction, which remains constant, and the variable subframe is a subframe having a variable transmission direction; and the network side communicating with a terminal on the basis of the subframes in the wireless frame. Employment of the method of the present application allows for the ability to meet the needs of the service in the cell, and for improved system efficiency and system performance.
