1. A data transmission method, the method being applied to a terminal and comprising:
mapping to-be-sent sidelink data to one or more logical channels corresponding to a sidelink, wherein data corresponding to different radio access methods are not mapped to a same logical channel;
obtaining an access method set for each of the one or more logical channels to which the to-be-sent sidelink data is mapped, wherein the access method set comprises at least one radio access method supported by data corresponding to each of the one or more logical channels;
sending a channel configuration message to a base station, wherein the channel configuration message is used to indicate the access method set for each of the one or more logical channels corresponding to the sidelink in the terminal, the channel configuration message comprises the access method set for each of the one or more logical channels, and the channel configuration message further comprises identities of the logical channels and Quality of Service (QoS) parameters of the data in the logical channels;
receiving a reconfiguration message sent by the base station, wherein the reconfiguration message is used to indicate radio access methods corresponding to the logical channels, and the reconfiguration message is generated by the base station according to sidelink resource congestion conditions corresponding to the access method set, wherein the reconfiguration message comprises an identity of a target logical channel and a first radio access method corresponding to the target logical channel; the target logical channel is part or all of the one or more logical channels, and the first radio access method is different from a second radio access method used by the terminal to send the channel configuration message; and
sending the sidelink data in the one or more logical channels on the sidelink according to corresponding radio access methods for the one or more logical channels as indicated by the reconfiguration message.
