UPLINK CHANNEL STATE INFORMATION REPORTING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18291514 titled 'UPLINK CHANNEL STATE INFORMATION REPORTING
The patent application describes methods, systems, and devices for wireless communications, specifically focusing on uplink channel state information (CSI) reporting to support transmission precoding matrix indicator (TPMI) selection.
- User equipment (UE) receives CSI reference signals (CSI-RSs) and performs measurements on them.
- The UE transmits an uplink CSI report to a base station based on the measurements, including candidate TPMIs, rank indicators (RIs), or both.
- The base station tests the candidate TPMIs and selects one for subsequent signaling based on received sounding reference signals (SRSs).
- An uplink grant is transmitted to the UE indicating the selected TPMI via downlink control information (DCI).
Potential Applications: - 5G and beyond wireless communication systems - Mobile networks - Internet of Things (IoT) devices
Problems Solved: - Efficient uplink CSI reporting for better communication quality - Optimal TPMI selection for improved data transmission
Benefits: - Enhanced wireless communication performance - Increased network capacity and reliability - Better user experience in mobile and IoT applications
Commercial Applications: Title: "Advanced Wireless Communication Systems for Enhanced Data Transmission" This technology can be utilized in telecommunications companies, IoT device manufacturers, and network infrastructure providers to improve the efficiency and reliability of wireless communications.
Questions about the technology: 1. How does this technology improve the overall performance of wireless communication systems? 2. What are the key factors considered in selecting the optimal TPMI for data transmission in this innovation?
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure provide techniques for uplink channel state information (CSI) reporting that supports transmission precoding matrix indicator (TPMI) selection. A user equipment (UE) may receive CSI reference signals (CSI-RSs), and may perform measurements on the CSI-RSs. The UE may transmit an uplink CSI report to a base station based on the measurements. The CSI report may include an indication of a set of one or more candidate TPMIs, rank indicators (RIs), or both. The base station may test the candidate TPMIs, one or more other TPMIs, or both, to received sounding reference signals (SRSs) and select a TPMI for subsequent signaling. The base station may transmit an uplink grant (e.g., via downlink control information (DCI)) indicating the selected TPMI. The DCI may be a single-stage DCI a timeline.
