Uplink scheduling method in time division duplex system

The invention discloses an upstream scheduling method of a time division duplex system, which forms a bound subframe by binding at least two upstream subframes of a radio frame, and establishes a corresponding relation which contains a one-to-one corresponding relation between the bound subframe and an upstream scheduling signal. The upstream scheduling method of the time division duplex system comprises the following steps: the upstream scheduling signal is received; according to the established corresponding relation, information of the bound subframe which is corresponding to the received upstream scheduling signal is determined, and the corresponding bound subframe is scheduled. The upstream scheduling method of the time division duplex system can realize the scheduling of at least two upstream subframes by a single upstream scheduling signal.
