15. A method by a Base Station (BS), comprising:
sending, to a user equipment (UE), one or more messages that include sounding reference signal (SRS) configuration information to indicate an SRS resource allocation, wherein the SRS configuration information includes a partial frequency sounding indicator and additional information to indicate a size of an SRS subband; and
receiving, from the UE, an SRS transmitted using a group of contiguous resource blocks (RBs) in a symbol in a first slot, wherein the group of contiguous RBs are determinable based on the size of the SRS subband and the partial frequency sounding indicator.
