Abstract: This application provides a communications method and device, and a computer-readable storage medium. The method includes: receiving an uplink data transmission threshold from a first network device, where the uplink data transmission threshold includes both a first transmission threshold and a second transmission threshold or includes a second transmission threshold. The first transmission threshold is used to indicate a maximum size of a data packet supported by the terminal device in a non-connected state on a first uplink carrier, and the second transmission threshold is used to indicate a maximum size of a data packet supported by the terminal device in the non-connected state on a supplementary uplink (SUL) carrier. The method further comprises determining, based on the uplink data transmission threshold and a size of a to-be-transmitted uplink data packet, to transmit, in the non-connected state, the uplink data packet on the first uplink carrier or the SUL carrier.

Abstract: Embodiments of this application provide a communication method and a communication apparatus. In the method, a terminal device obtains a first RA report that includes information about a random access procedure initiated by the terminal device to a source secondary access network device. After the master access network device of the terminal device changes from a source master access network device to a target access network device, the terminal device sends a first message to the target access network device. The first message includes the first RA report and first identification information, and the first identification information indicates the source master access network device.

Abstract: A method is provided, including: configuring a conditional candidate primary secondary cell group cell PSCell addition or change for a terminal device; and performing, by a master network device, early data transmission oriented to a network device to which a candidate PSCell belongs, and for example, before the terminal device accesses the candidate PSCell, sending a data packet to the network device to which the candidate PSCell belongs, where a form of the data packet is a packet data convergence protocol protocol data unit, and the data packet includes a data packet on an MN terminated secondary cell group bearer and/or a data packet on an MN terminated split bearer. In this way, after the terminal device accesses a candidate network device, the candidate network device may send forwarded data to the terminal device, to reduce a data transmission delay.
