In an embodiment, different types of RACH resources occupy different time lengths and/or frequency-domain widths and/or numbers of subcarriers, or different types of RACH resources employ different numerologies, or different types of RACH resources are used for transmitting different preambles, or different types of RACH resources are used for transmitting different preambles and data.

In an embodiment, different types of RACH resources correspond to different preamble configurations.

In an embodiment, as described above, the configuring unit 1503 may further configure a set of preambles, which shall not be described herein any further.

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 network device, including the uplink transmission control apparatus 1500 as described in Embodiment 3.

FIG. 16 is a schematic diagram of the network device of this embodiment. As shown in FIG. 16, a network device 1600 may include a processor 1601 and a memory 1602, the memory 1602 being coupled to the processor 1601. The memory 1602 may store various data, and furthermore, it may store a program 1603 for information processing, and execute the program under control of the processor 1601, to receive various information transmitted by the UE, and transmit various information to the UE.
