CSI ENHANCEMENT FOR SBFD CONFIGURATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240107461 titled 'CSI ENHANCEMENT FOR SBFD CONFIGURATION
Simplified Explanation
A network node may transmit a Reference Signal (RS) to a User Equipment (UE) in a symbol or a slot. The RS may cover multiple downlink subbands with non-contiguous subcarriers in the symbol or slot. Some downlink subbands may be separated by an uplink subband. The RS may include a Channel State Information RS (CSI-RS) for the UE to measure and generate CSI metrics. The UE sends a CSI report to the network node based on the RS and CSI metrics.
- Network node transmits RS to UE in symbol or slot
- RS covers multiple non-contiguous downlink subbands

Original Abstract Submitted
a network node may transmit an rs to a ue in a symbol or a slot. the rs may extend over a plurality of downlink subbands that have non-contiguous subcarriers in the symbol or the slot. at least two downlink subbands in the plurality of downlink subbands may be separated by an uplink subband in the symbol or the slot. the plurality of downlink subbands and the uplink subband may be associated with a subband full duplex operation at a network node. the rs may include a csi-rs. the ue may measure the rs from the network node in the symbol or the slot. the ue may generate at least one csi metric based on the measurement of the rs. the network node may receive a csi report from the ue based on the rs and at least one csi metric.
