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.
