1. A data processing method, comprising:
obtaining, by a network device, target information of a target beam or a target cell, wherein the target information comprises a transmission delay difference and a reference multi-path delay corresponding to the target beam or the target cell, the transmission delay difference is a difference between communication round trip delays corresponding to a first location and a second location, the first location is a location corresponding to a reference point in a coverage region of the target beam or the target cell, and the second location is a location farthest from the network device in the coverage region of the target beam or the target cell;
determining, by the network device based on the transmission delay difference in the target information, a first preamble format required for a random access preamble corresponding to the target beam or the target cell;
determining, by the network device based on the reference multi-path delay, a second preamble format required for a random access preamble corresponding to the target beam or the target cell;
determining, by the network device, first configuration information of a random access occasion from one or more types of configuration information based on the first preamble format, wherein the first configuration information indicates the first preamble format and a first set of random access occasions comprised in a random access period, and wherein an interval between random access occasions comprised in the first set of random access occasions is greater than or equal to a preamble length corresponding to the first preamble format; and
generating, by the network device, a first configuration index based on the first configuration information.
