Abstract: Embodiments of this application provide a configuration method and apparatus. When indicating, by using an RRC connection release message, a terminal to enter an inactive state from a connected state, a network device may include, in the RRC connection release message, a configuration parameter allocated to the terminal in the inactive state. That is, the terminal receives the radio resource control RRC connection release message sent by the network device, where the RRC connection release message includes first information used to indicate a target configuration parameter. In this way, the terminal may enter the inactive state based on the RRC connection release message, and determine a context parameter of the inactive state based on the first information, so that the configuration parameter is properly allocated to the terminal in the inactive state.

Abstract: A random access method is provided including: a terminal side device obtains first uplink data from a first message buffer, wherein the first message buffer is a buffer specific to a first random access procedure, the first random access procedure is a procedure in which the terminal side device sends a first random access request, sends the first uplink data on a first uplink resource, and receives response information, and the response information is a first random access response to the first random access request or a response to the first uplink data. The terminal side device sends the first random access request to a network side device, and sends the first uplink data to the network side device on the first uplink resource. The terminal side device detects downlink control information, wherein the downlink control information indicates a resource of the response information.

Abstract: This application provides an uplink transmission method and a communication apparatus. When a terminal device does not obtain a TA value in a two-step random access process, the terminal device can transmit, based on a preset TA value or a maintained TA value, uplink data on an uplink transmission resource assigned in the second step of random access, or perform, based on a preset TA value or a maintained TA value, a feedback for downlink data transmitted on a downlink transmission resource assigned in the second step of random access. In this way, uplink synchronization can be implemented when no TA value is assigned in a random access process.
