SUBBAND CHANNEL STATE INFORMATION PAYLOAD REDUCTION IN A FULL-DUPLEX NETWORK - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240340063 titled 'SUBBAND CHANNEL STATE INFORMATION PAYLOAD REDUCTION IN A FULL-DUPLEX NETWORK
Simplified Explanation: The patent application describes a method for configuring subbands for channel state information reporting in a user equipment (UE) device. The UE transmits a reduced CSI report payload with fewer bits by using various techniques such as differential CSI values or reporting CSI values for only a subset of subbands.
- Bandwidth part configured for subband full duplexing with an uplink subband
- Subbands in the first plurality decrease in size closer to the uplink subband
- Reduced CSI report payload with fewer bits than traditional methods
- Techniques to reduce the number of bits in the CSI report payload
- Fallback subband configuration with equal-sized subbands
Potential Applications: - 5G and future wireless communication systems - IoT devices requiring efficient channel state information reporting - Network optimization for improved spectral efficiency
Problems Solved: - Efficient utilization of bandwidth for CSI reporting - Reduction of overhead in CSI report payloads - Enhanced performance in subband full duplexing scenarios
Benefits: - Improved spectral efficiency - Reduced signaling overhead - Enhanced overall network performance
Commercial Applications: Title: Enhanced CSI Reporting for 5G Networks This technology can be utilized by telecommunication companies to optimize network performance and enhance spectral efficiency in 5G and future wireless communication systems. It can also benefit IoT device manufacturers looking to improve the efficiency of channel state information reporting in their devices.
Prior Art: Prior art related to this technology may include research papers, patents, or standards documents in the field of wireless communication systems, particularly focusing on CSI reporting and subband configurations.
Frequently Updated Research: Researchers in the field of wireless communication systems are constantly exploring new techniques and algorithms to improve CSI reporting efficiency and spectral utilization. Stay updated with the latest advancements in this area to leverage cutting-edge technologies for network optimization.
Questions about CSI Reporting Optimization: 1. How does differential CSI values help in reducing the CSI report payload size? 2. What are the implications of using a fallback subband configuration with equal-sized subbands in terms of network performance and efficiency?
Original Abstract Submitted
a user equipment (ue) receives a configuration of a first plurality of subbands having different sizes for channel state information (csi) reporting. the configuration is for a bandwidth part configured for subband full duplexing with an uplink subband. a size of the subbands in the first plurality of subbands decreases closer in frequency to the uplink subband. the ue transmit a reduced csi report payload including a plurality of csi values, the reduced csi report payload having fewer bits than a size of an absolute csi value times a number of subbands in the first plurality of subbands. the ue may reduce the number of bits in the csi report payload using differential csi values instead of absolute csi values, reporting csi values for only a subset of the subbands, or using a fallback subband configuration with equal sized subbands.
