This disclosure provides systems, methods, and devices for wireless communication that support (CSI-RS) configuration enhancements for subband full-duplex (SBFD) operations. In a first aspect, a device for wireless communication includes at least one processor and a memory coupled to the at least one processor. The at least one processor is configured to receive a control channel transmission including CSI-RS resource configuration information from a second network node. The at least one processor is further configured to receive, in a SBFD slot, a CSI-RS transmission from the second network node based on CSI-RS sequence information, CSI-RS frequency resource information, or both, wherein the CSI-RS sequence information, the CSI-RS frequency resource information, or both, are determined based on the CSI-RS resource configuration information, and wherein CSI-RS resources of the CSI-RS transmission occupy two or more downlink subbands of the SBFD slot. Other aspects and features are also claimed and described.
