Embodiments of the present invention provide a method and apparatus for transmitting control signaling. The method includes: transmitting indication information on a transmission location of control signaling by a base station to a mobile station configured as an open-loop MIMO transmission mode; and transmitting the control signaling by the base station in a data region by using the open-loop MIMO transmission mode or a transmit diversity transmission mode if the location for transmitting the control signaling indicated by the indication information on a transmission location of control signaling is located at the data region. With the method and base station of this embodiment, in a case where the number of mobile stations that need to be scheduled in a cell is increased and it is resulted in that the scheduling information needing to be transmitted in a subframe is increased, the control signaling of a mobile station configured as an open-loop MIMO transmission mode is placed in a data region for transmission, thereby increasing the number of UE the can be scheduled, increasing the throughput of the system, and solving the problem that the capacity of a PDCCH is limited. |
