Abstract
The controlling of the network traffic is implemented in a communication network by obtaining first configuration parameters for physical random access channel (PRACH) preambles, the first configuration parameters including a first preamble format, a zero correlation zone configuration index, and a list of physical root Zadoff-Chu sequence indexes. A set of cyclic shifts corresponding to a first frequency offset is generated based on the first preamble format, the zero correlation zone configuration index, and the list of physical root Zadoff-Chu sequence indexes. Second configuration parameters are exported in order to control network traffic, the second configuration parameters including the set of cyclic shifts.
