An example method for wireless communication, based on the disclosed technology, includes transmitting data over at least one transmission link that is configured based on a mapping between two reference signals, each of which is configured with different subsets of one or more network parameters. Another example method includes dividing a plurality of SRS (sounding reference signal) resource sets into a plurality of groups based on network parameters of SRS resources or SRS resource sets, and transmitting, within one of the plurality of groups, only one SRS resource in each of multiple SRS resource sets at an identical time, where the SRS resources in different SRS resource sets can be transmitted simultaneously.
