Summary

The USPTO has published a patent application (US20260088872A1) detailing a method for wireless terminals in New Radio (NR) systems to generate and transmit Channel State Information (CSI) reports. The application describes a process involving receiving configuration and trigger information via a physical downlink control channel (PDCCH) and transmitting the CSI report on a physical uplink shared channel (PUSCH).

What changed

This document is a published patent application, not a regulatory rule or guidance. It describes a novel method for wireless terminals in New Radio (NR) systems to efficiently report Channel State Information (CSI). The proposed method involves receiving downlink control information (DCI) that includes configuration for physical uplink shared channels (PUSCHs) and trigger information for CSI reports. Upon receiving the trigger, the wireless terminal generates the CSI report and transmits it on a selected PUSCH associated with one of the serving cells.

As a patent application, this document does not impose immediate regulatory obligations or compliance deadlines on entities. However, if granted as a patent, it could establish intellectual property rights related to CSI reporting mechanisms in 5G and future wireless systems. Companies involved in developing or deploying NR systems, particularly those related to network scheduling and performance optimization, should be aware of this application as it may impact future technology development and licensing considerations.

Abstract

A method for a wireless terminal of a New Radio (NR) system is provided. The method includes receiving, in a physical downlink control channel (PDCCH) associated with a first serving cell of a plurality of serving cells, downlink control information (DCI). The DCI includes configuration information for one or more physical uplink shared channels (PUSCHs), each PUSCH of the one or more PUSCHs being associated with a corresponding one of one or more of the plurality of serving cells. The DCI also includes trigger information to trigger a generation of a channel state information (CSI) report at the wireless terminal. The method further includes generating, in response to receiving the trigger information, the CSI report, selecting the PUSCH associated with one serving cell of the one or more of the plurality of serving cells, and transmitting the CSI report on the PUSCH associated with the one serving cell.
