摘要

An uplink transmission control method and apparatus and a communication system. The network device explicitly or implicitly indicates dynamic scheduling information of RACH resources via control signaling. After selecting RACH resources, the user equipment (UE) monitors control signaling corresponding to the RACH resources. According to situations of receiving the control signaling, when the selected RACH resources are available, the UE directly transmits a random access request matched with the RACH resources; and when the selected RACH resources are unavailable, the UE further selects RACH resources according to configuration or indication of a base station, and until an RACH resource is available, the UE transmits a random access request matched with the RACH resource. Hence, normal random access of the UE may be ensured, and interference to other UEs may be reduced.

說明書

Furthermore, as shown in FIG. 16, the network device 1600 may further include a transceiver 1604, and an antenna 1605, etc. Functions of the above components are similar to those in the related art, and shall not be described herein any further. It should be noted that the network device 1600 does not necessarily include all the parts shown in FIG. 16, and furthermore, the network device 1600 may include parts not shown in FIG. 16, and the related art may be referred to.

With the network device of this embodiment, normal random access of the UE may be ensured, and interference to other UEs may be reduced.

Embodiment 5

This embodiment provides an uplink transmission control apparatus. As principles of the apparatus for solving problems are similar to that of the method in Embodiment 2, the implementation of the method in Embodiment 2 may be referred to for implementation of the apparatus, with identical contents being not going be described herein any further.
