Claim 19:
20. An apparatus comprising:
one or more processors; and
a non-transitory computer readable storage medium, configured to store instructions executable by the one or more processors,
wherein the one or more processors are configured to:
detect a current timing advance (TA) in a target time unit to obtain a detection result, wherein the target time unit is a time unit preceding a first time unit corresponding to a first target resource, the first target resource is a random access resource unit associated with a second target resource and meeting a specified condition, and the second target resource is a resource unit in a resource set which is pre-allocated to the user equipment by a base station for reporting grant-free data; and
send at least one of a random access signal and a target notification message to the base station, in response to that the detection result indicates that the current TA has expired, wherein the random access signal is configured to indicate that the base station needs to reconfigure a new 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 the second target resource.
