    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.

    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.
