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.
