Claim 9:
10. A method for data transmission, applied to a base station and comprising:
detecting whether at least one of a random access signal and a target notification message sent by a user equipment is received, wherein the random access signal is configured to indicate that the base station needs to reconfigure a new Timing Advance (TA) for the user equipment and to indicate that the base station does not reserve a third target resource for the user equipment, or wherein the random access signal is configured to indicate that the base station needs to reconfigure the new TA for the user equipment, and the target notification message is configured to indicate that the base station does not reserve a third target resource for the user equipment, wherein the third target resource comprises at least a second target resource, and the second target resource is a resource unit in a resource set which is pre-allocated to the user equipment by the base station for reporting grant-free data;
reconfiguring and returning a new timing advance (TA) to the user equipment according to the random access signal, in response to that at least one of the random access signal and the target notification message is detected; and
no longer reserving the third target resource for the user equipment according to at least one of the random access signal and the target notification message.
