The present disclosure relates to methods and devices for signaling enhancements. In one aspect, a User Equipment (UE) can receive a configuration to transmit one or more sounding reference signals (SRSs) based on a downlink control information (DCI). The UE can also receive an indication of a plurality of non-contiguous resource blocks (RBs) based on the DCI. The UE can transmit a first SRS on a first set of one or more RBs of the plurality of non-contiguous RBs. Additionally, the UE can transmit a second SRS on a second set of one or more RBs of the plurality of non-contiguous RBs. The first set of one or more RBs and the second set of one or more RBs may be separated by a distance of at least one RB.
