Abstract: The present disclosure discloses a random access transmission method and a terminal. The method includes: obtaining a data scrambling parameter of a physical uplink shared channel PUSCH; and sending a random access message based on the data scrambling parameter, where the random access message corresponds to the PUSCH and a physical random access channel PRACH. In a random access process of a terminal in embodiments of the present disclosure, a random access message is sent on a random access resource based on a data scrambling parameter of a PUSCH. Correspondingly, a network device decodes the PUSCH on the random access resource based on the data scrambling parameter, to obtain the corresponding random access message.

Abstract: This application discloses a transmit power determining method and apparatus, a terminal, and a network side device. The transmit power determining method includes: receiving, by a terminal, L pieces of configuration information sent by a network side device; and determining, by the terminal based on the L pieces of configuration information, a transmit power for performing uplink transmission on a target uplink resource. The L pieces of configuration information include first power control configuration information and/or at least one piece of second power control configuration information, and L is greater than or equal to 1. The first power control configuration information is used to determine a transmit power of the terminal for performing uplink transmission on a first uplink resource. Each piece of the second power control configuration information is used to determine a transmit power of the terminal for performing uplink transmission on a second uplink resource.
