US 12,587,247 B2 · Subband reporting for full duplex operation

Abstract

A computer-readable storage medium stores instructions for execution by one or more processors of a UE to configure the UE for SBFD operation in a 5G NR network, and to cause the UE to decode RRC signaling received from a base station and including at least one CSI-RS resource set with time-frequency resource allocation associated with a CSI-RS transmission. A CSI reporting band is determined with a plurality of PRBs based on the RRC signaling. The CSI reporting band including a subset of the plurality of PRBs associated with one or more DL subband(s) in symbols or slots identified via higher layer signaling or a combination of higher layer and Layer 1 signaling for SBFD operation. Channel measurements are performed based on CSI-RSs transmitted during the CSI-RS transmission. The measurements are associated with the subset of the plurality of PRBs in the CSI reporting band.
