CSI REPORTING SUBBAND GRANULARITY CONFIGURATION IN FULL DUPLEXING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18360774 titled 'CSI REPORTING SUBBAND GRANULARITY CONFIGURATION IN FULL DUPLEXING
Simplified Explanation
The abstract describes a method for a network entity to configure a User Equipment (UE) to transmit subband Channel State Information (CSI) reports in full duplex slots. The UE receives a CSI report configuration indicating multiple CSI subbands within a bandwidth part (BWP). The UE then receives a CSI Reference Signal (CSI-RS) in a slot associated with a full duplex mode, which includes both downlink and uplink subbands. The UE transmits a CSI report containing CSI associated with a first CSI subband overlapping with the downlink subband, but lacking CSI for a second subband overlapping with the uplink subband.
- Network entity configures UE to transmit subband CSI reports in full duplex slots
- UE receives CSI report configuration indicating multiple CSI subbands within a BWP
- UE receives CSI-RS in slot associated with full duplex mode
- UE transmits CSI report with CSI for first subband overlapping with downlink subband
- CSI report lacks CSI for second subband overlapping with uplink subband
Potential Applications
- 5G and beyond wireless communication systems
- Improving efficiency and reliability of communication networks
Problems Solved
- Efficient configuration and transmission of subband CSI reports in full duplex slots
- Enhancing communication performance in full duplex mode
Benefits
- Better utilization of resources in wireless networks
- Enhanced communication quality and reliability
Original Abstract Submitted
Aspects are provided which allow a network entity to configure and a UE to transmit subband CSI reports in full duplex slots. Initially, the UE receives a CSI report configuration indicating a plurality of CSI subbands of at least one bandwidth part BWP. Subsequently, the UE receives a CSI-RS in a slot associated with a full duplex mode, the slot being further associated with a frequency band including a downlink subband and an uplink subband. Afterwards, the UE transmits a CSI report, where the CSI report includes first CSI associated with the CSI-RS for a first one of the CSI subbands overlapping in frequency with the downlink subband, and the CSI report lacks second CSI for a second one of the CSI subbands overlapping in frequency with the uplink subband.
