Disclosed by the present invention are a communication method and apparatus for uplink carrier aggregation (CA). The method is applied to a communication system which supports uplink CA, and the communication system comprises a first uplink carrier and a second uplink carrier, the first uplink carrier using a frequency division duplex (FDD) mode, and the second uplink carrier using a time division duplex (TDD) mode. The method comprises: a base station where the second uplink carrier is located determining configuration information of uplink control information (UCI), the configuration information comprising resource configuration information, the resource configuration information being used for indicating a resource which transmits the UCI, and the resource being located in a downlink subframe in a TDD mode and/or a special subframe; and the base station sending the configuration information to a terminal. The communication method and apparatus for uplink CA of the embodiments of the present invention may improve transmission efficiency.
