Abstract: An uplink transmission method and a communication apparatus. A terminal device receives first indication information indicating at least two uplink carriers to effectively reduce control signaling overheads. The terminal device sends uplink transmission on the at least two uplink carriers based on the first indication information. The uplink transmission is sent on the at least two uplink carriers in response to control signaling overheads being reduced. The use of the at least two uplink carriers increases an uplink capacity.
