In an embodiment, as shown in FIG. 18, the first determining unit 1702 includes: a second judging unit 1801, a third determining unit 1802 and a selecting unit 1803. The second judging unit 1801 determines whether the selected RACH resources are available according to a result of monitoring the control signaling; the third determining unit 1802 determines that the selected RACH resources are available RACH resources when it is yes determined by the second judging unit 1801; and the selecting unit 1803 reselects RACH resources when it is no determined by the second judging unit 1801, to determine available RACH resources.

In an implementation, the selecting unit 1803 selects other RACH resources than unavailable RACH resources from a set of RACH resources configured by the network device, or selects available RACH resources indicated by the network device via the control signaling as the available RACH resources.

In an implementation, the control signaling indicates the dynamic scheduling information of the RACH resources by indicating whether the selected RACH resources are available or by indicating the available RACH resources.

With the uplink transmission control apparatus of this embodiment, normal random access of the UE may be ensured, and interference to other UEs may be reduced.

This embodiment provides a UE, including the uplink transmission control apparatus 1700 as described in Embodiment 5.
