CSI REPORTING FOR MULTI-TRP COHERENT JOINT-TRANSMISSION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240284220 titled 'CSI REPORTING FOR MULTI-TRP COHERENT JOINT-TRANSMISSION

The patent application discusses methods and apparatuses for channel state information (CSI) reporting for multi-transmit receive point (TRP) coherent joint transmission (CJT).

The method involves receiving a configuration about a CSI report, determining information for the CSI report based on N CSI-RS resources, and partitioning the CSI report into two parts (CSI Part 1 and CSI Part 2).
The CSI Part 2 is further partitioned into three groups (G0, G1, and G2), with G1 including an indicator for each of N-1 CSI-RS resources indicating a frequency-domain offset relative to a reference CSI-RS resource.

Potential Applications: - This technology can be applied in wireless communication systems to improve the efficiency and accuracy of channel state information reporting. - It can enhance the performance of multi-transmit receive point systems by optimizing the transmission of CSI reports.

Problems Solved: - Streamlining the process of CSI reporting in multi-transmit receive point systems. - Enhancing the reliability and accuracy of channel state information in coherent joint transmission scenarios.

Benefits: - Improved communication system performance. - Enhanced spectral efficiency. - Better utilization of resources in multi-transmit receive point setups.

Commercial Applications: Title: Enhanced Channel State Information Reporting for Wireless Communication Systems This technology can be utilized in 5G and beyond networks, IoT devices, smart city infrastructure, and industrial automation systems to optimize communication performance and resource allocation.

Questions about the technology: 1. How does this technology improve the efficiency of channel state information reporting in wireless communication systems? 2. What are the key advantages of partitioning the CSI report into two parts and three groups as described in the patent application?

Original Abstract Submitted

methods and apparatuses for channel state information (csi) reporting for multi-transmit receive point (trp) coherent joint transmission (cjt). a method includes receiving a configuration about a csi report. the configuration includes information about (i) ncsi reference signal (csi-rs) resources. the method further includes, based on the configuration, determining information for the csi report based on n csi-rs resources; partitioning the csi report into two parts, a csi part 1 and a csi part 2; and partitioning the csi part 2 into three groups, g0, g1, and g2. the method further includes transmitting the csi part 1 and at least a portion of the csi part 2. the group g1 includes an indicator indicating, for each of n−1 csi-rs resources of the n csi-rs resources, a frequency-domain (fd) offset d∈{0, 1, . . . , no−1} relative to a reference csi-rs resource.
