Abstract: This application provides a random access method and a communication apparatus. The method includes: receiving, by a terminal device, a response message from a network device; determining, by the terminal device, a message format of the response message, where the message format includes a first format or a second format; and parsing, by the terminal device, the response message based on the determined message format, where the response message in the first format includes a contention resolution identity and a control plane message; and the response message in the second format includes a contention resolution identity and includes no control plane message. A two-step random access method provided in this application includes two message formats of a random access response.

Abstract: Embodiments of this application disclose a data transmission method and an apparatus. The method includes: When a terminal device is in a radio resource control RRC inactive state, the terminal device selects a first synchronization signal block SSB at first time, and sends first small data transmission SDT data to a network device by using a first configured grant CG resource corresponding to the first SSB; and when signal quality of a plurality of SSBs at second time is greater than a first threshold, the terminal device preferentially selects the first SSB from the plurality of SSBs at the second time, and sends second SDT data to the network device by using a second CG resource corresponding to the first SSB.

Abstract: This application discloses an indoor-outdoor determining-based uplink transmission method and apparatus. A terminal device or a positioning device determines whether the terminal device is located indoors or outdoors. The terminal device or the positioning device sends a first message to an access network device, where the first message includes a first information element, and the first information element indicates whether the terminal device is located indoors or outdoors. The access network device determines an access parameter of the terminal device based on the first information element, where the access parameter includes an access frequency. According to the method disclosed in embodiments of this application, uplink transmission of the terminal device in a proper frequency band is implemented, and communication interference is reduced.
