1. A method for configuring random access channel (RACH) resources, applied to a terminal device, wherein the method comprises:
receiving configuration information sent by a network device, wherein the configuration information is used to configure time domain resources and frequency domain resources of the RACH resources, the RACH resources correspond to multiple groups of frequency domain resources, the multiple groups of frequency domain resources do not overlap, and frequency domain resources corresponding to RACH resources on different time domain resources are different within each preset time, wherein the preset time represents a time length of a receiving window for a random access preamble; and
sending the random access preamble to the network device on the RACH resources.
