1. An uplink transmission sending method, comprising:
determining a sending mechanism of an uplink transmission according to an uplink transmit mode in a case of multiple carriers; and
sending the uplink transmission according to the sending mechanism;
wherein the uplink transmission sending method further comprises:
determining the uplink transmit mode according to configuration information of a reference configuration;
wherein a time unit comprises at least one of a subframe, a slot, or an orthogonal frequency-division multiplexing (OFDM) symbol;
when the time unit is the OFDM symbol, the determining the uplink transmit mode according to the configuration information of the reference configuration comprises:
determining the uplink transmit mode to be a first mode for the OFDM symbol configured to be uplink in the reference configuration, and determining the uplink transmit mode to be a second mode for the OFDM symbol configured to be non-uplink in the reference configuration; or
determining the uplink transmit mode to be a second mode for the OFDM symbol configured to be uplink in the reference configuration, and determining the uplink transmit mode to be a first mode for the OFDM symbol configured to be non-uplink in the reference configuration;
wherein the uplink transmit mode comprises a first mode and a second mode;
when uplink transmit resources comprise antenna ports supported by a sounding reference signal (SRS) resource, in the first mode, each of two uplink carriers supports the uplink transmission in which one port is supported by the SRS resource, and in the second mode, one of the two uplink carriers supports uplink transmissions in which at most two ports are supported by the SRS resource, and the other of the two uplink carriers supports no uplink transmission.
