A method and an apparatus for an uplink control signaling transmission in a time division duplex OFDMA system are provided for the long term evolution time division duplex (LTE TDD). A signaling processing unit reserves frequency resource for an uplink control channel according to the total amount of the uplink control signaling, and the reserved frequency resource are assigned on both sides of the frequency domain used by uplink time slots, so that the uplink control signaling of a terminal UE is transmitted on the position and the bandwidth of the reserved frequency resource. The transmitted uplink control signaling is transmitted on respective reserved uplink control sub-channels by an intra-subframe hopping way, each terminal UE or a group of UEs corresponding to a frequency-hop sequence. The present invention is simple to realizes and capable of utilizing resource repeatedly and utilizing the time domain and frequency domain diversity simultaneously.
