1. A method for wireless communication at a user equipment (UE) in a wireless communication network, the method comprising:
receiving downlink control information that includes a partial frequency sounding configuration for the UE;
transmitting a sounding reference signal (SRS) in one or more resources configured for SRS transmission in a bandwidth used by the UE, the one or more resources being identified by the partial frequency sounding configuration; and
refraining from transmitting in a portion of a set of resources configured for SRS transmission in the bandwidth used by the UE;
wherein the downlink control information has a format that is based on group common downlink control information (GC-DCI) defined for use in a fifth-generation new radio (5G NR) network;
wherein the format of the downlink control information is based on GC-DCI 2_3 Type A and includes a partial frequency sounding field that includes a resource index used to identify the one or more resources in a preconfigured table, or includes a bitmap having a plurality of bits, each bit in the bitmap being mapped to a subset of the one or more resources.
