摘要： A signal transmission method in a Time Division Duplex (TDD) system is disclosed. The method comprises following steps: within a time length of a half-frame of a radio frame, base station transmits signal on a downlink special time slot, thereafter does not transmit signal on a Guard Period (GP), and then receives signal on an uplink special time slot; all time lengths of other uplink or downlink normal time slots for transmitting signal are equal; the total time length of the downlink special time slot, the guard period and the uplink special time slot is integer times of the time length of an uplink or downlink normal time slot. In addition, a frame structure adopted in the TDD system which corresponds to the method is disclosed. The present invention makes it flexible to set the duration of the GP and it is guaranteed that, even if a synchronization signal adopts power promotion, it will not bring great interference to uplink reception of other base stations; in addition, the utilization efficiency of the system is improved.

摘要： The present invention discloses a method and device for sending a message in a physical uplink control channel. The present invention overcomes the problem that an index of the physical uplink control channel corresponding to a ACK/NACK message can not be represented implicitly in prior art by using the known downlink information, which includes an index of the control channel element where control signaling associated with downlink data is located and an index of a sub-frame where the downlink data is located. Therefore, the index of the physical uplink control channel where the ACK/NACK message associated with the downlink data is located can be represented and the ACK/NACK message can be sent in an appropriate physical uplink control channel.

摘要： The present invention provides a method for transmitting a PDCCH (physical downlink control channel) signal, when the number of available resource blocks of the downlink bandwidth in a radio frame is less than or equal to k, 2 symbols are fixedly used to transmit the physical downlink control channel, wherein k is a natural number. The present invention further provides another method for transmitting a PDCCH signal. In a TDD Long Term Evolution system, when the number of available resource blocks of the downlink bandwidth in a radio frame is less than or equal to k and the uplink/downlink switching period is 10 ms, the transmitting end selects 2, 3 or 4 symbols to transmit the PDCCH signal in subframe 6. With the transmission method of the PDCCH signal provided in the present invention, the utilization efficiency of the system resources and the transmission performance of PDCCH can be improved.
