Abstract: Embodiments of the present invention provide an uplink transmission method and an apparatus. When a first data packet and a second data packet are simultaneously transmitted, UE maps the first data packet to a first time-frequency resource of a time-frequency resource block, maps the second data packet to a second time-frequency resource of the time-frequency resource block, sends the first data packet and the second data packet by using different time-frequency resources of the same time-frequency resource block, and feeds back a receiving result of the first data packet and the second data packet by using a new feedback mechanism. In this way, a conflict between an initially transmitted data packet and a retransmitted data packet in an SPS scenario can be avoided, and time-frequency resources can be more effectively used.

Abstract: The disclosure describes example methods. One example method includes obtaining sidelink transmit power and uplink transmit power, where the sidelink transmit power is transmit power of a sidelink in a first time unit, and the uplink transmit power is transmit power of an uplink in the first time unit. An actual transmit power of the sidelink in the first time unit based on the sidelink transmit power, the uplink transmit power, and maximum transmit power. The first time unit includes N first time subunits, M second time subunits in the N first time subunits overlap uplink resources, M is less than or equal to N. The N first time subunits are time subunits used for sidelink transmission in the first time unit, and the actual transmit power of the sidelink is constant in the N first time subunits.
