1. A method for data transmission, applied to a terminal, comprising:
starting, by the terminal, a target timer corresponding to a target sidelink logical channel;
determining, by the terminal, a target resource based on whether resource configuration information transmitted by a base station is received before the target timer expires, wherein the resource configuration information comprises resource information of a first resource configured by the base station for the terminal, and the first resource is configured to transmit target data to be transmitted on the target sidelink logical channel; and
transmitting the target data on the target sidelink logical channel through the target resource,
wherein starting, by the terminal, the target timer corresponding to the target sidelink logical channel, comprises:
determining whether a timer corresponding to any sidelink logical channel of the terminal satisfies a preset start timing condition; and
starting the target timer in response to that the target timer corresponding to the target sidelink logical channel satisfies the start timing condition,
wherein the start timing condition comprises:
the target sidelink logical channel comprises a sidelink buffer status report that needs to be transmitted to the base station; and
the target data transmitted by an application layer to the target sidelink logical channel is received,
wherein determining, by the terminal, the target resource based on whether the resource configuration information transmitted by the base station is received before the target timer expires, comprises:
determining a second resource in a preset resource pool in response to not receiving the resource configuration information before the target timer expires, wherein the preset resource pool is a sidelink resource pool which is pre-allocated by the base station to the terminal and used when the terminal does not obtain resource scheduling from the base station; and
using the second resource as the target resource.
