1. A method for determining frequency hopping for a channel, the method comprising:
receiving, by a terminal, first configuration information, and determining, based on the first configuration information, a first bandwidth size corresponding to the bandwidth part, wherein the first bandwidth size corresponding to the bandwidth part is less than or equal to a bandwidth size of a carrier;
determining, by the terminal, based on the first bandwidth size corresponding to the bandwidth part, a frequency hopping step-size corresponding to an uplink channel;
determining, by the terminal, a frequency domain position of a second step of frequency hopping based on a frequency domain position of a first step of frequency hopping and the frequency hopping step-size corresponding to the uplink channel, wherein the frequency domain position of the first step of frequency hopping and the frequency domain position of the second step of frequency hopping are frequency domain positions used for transmitting the uplink channel;
transmitting, by the terminal, the uplink channel based on the frequency domain positions,
wherein determining, by the terminal, based on the first bandwidth size corresponding to the bandwidth part, a frequency hopping step-size corresponding to an uplink channel comprises:
determining, by the terminal based on the following formula, the frequency hopping step-size corresponding to the uplink channel: WH=nW, wherein
WH is the frequency hopping step-size corresponding to the uplink channel,
W is the first bandwidth size corresponding to the bandwidth part,
n is a scale factor,
n=1/m, and
m is a positive integer greater than 1.
