1. A method, comprising:
receiving, by a user equipment (UE), a higher-layer signal configuring a fractional sounding-resource-signal (SRS) resource in configured resource blocks (RBs) from a network node, wherein the higher-layer signal comprises a scaling factor PF;
determining, by the UE, an SRS sequence length and a frequency-domain starting position of the fractional SRS resource based on the higher-layer signal; determining, by the UE, the fractional SRS resource according to the SRS sequence length and the frequency-domain starting position;
performing, by the UE, a frequency hopping in the fractional SRS resource according to a frequency hopping offset parameter, wherein the frequency hopping offset parameter is applied in repeated symbols within a frequency hopping period in an event that the fractional SRS resource is repeated to sound in the repeated symbols at the same frequency location in the frequency hopping period or in different frequency hopping periods in an event that the fractional SRS resource is repeated to sound at the same frequency locations in the different frequency hopping period; and
transmitting, by the UE, an SRS to the network node on the fractional SRS resource.
