The present invention relates to wireless communication, and in particular, a terminal device, a network device, and an uplink transmission method for solving a problem in a carrier aggregation scenario in which information such as downlink channel characteristics of a carrier cannot be acquired when an uplink reference signal is not transmitted. And an uplink reception method. In the terminal device, the processing module selects one or more normal carriers or special carriers from the first carrier set for the uplink subframe, where the first carrier set transmits the first uplink subframe. Including all carriers in the carrier aggregation used by the terminal equipment to transmit, the transmission module cancels the transmission of uplink subframes on one or more carriers, where the special carrier is the terminal equipment Is a carrier that does not transmit any uplink data or uplink control information in the uplink, and a normal carrier is a carrier used by a terminal device to transmit uplink data and / or uplink control information. Uplink subframes on some carriers are rejected, thereby solving the problem that information such as downlink channel characteristics of the carrier cannot be obtained when no uplink reference signal is transmitted on the carrier.
