CHANNEL STATE INFORMATION REPORTING FOR PARTIAL BANDS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17916781 titled 'CHANNEL STATE INFORMATION REPORTING FOR PARTIAL BANDS
Simplified Explanation
The patent application describes methods, systems, and devices for wireless communications. It focuses on a user equipment (UE) receiving a configuration message from a base station, which includes information about partial bands for channel state information reporting. The UE then selects antenna ports and calculates channel state information based on the configuration message, and transmits this information to the base station.
- The patent application introduces a method for configuring partial bands for channel state information reporting in wireless communications.
- It describes how a user equipment (UE) receives a configuration message from a base station, which includes information about the partial bands.
- Each partial band is smaller than the overall system bandwidth and consists of multiple frequency domain units associated with a precoder.
- The UE selects antenna ports for each partial band based on the configuration message.
- The UE calculates channel state information by combining the selected antenna ports using linear combination coefficients.
- The UE then transmits the channel state information to the base station, including an indication of the selected antenna ports and linear combination coefficients for each partial band.
Potential Applications
This technology has potential applications in various wireless communication systems, including:
- 5G and future generations of mobile networks
- Internet of Things (IoT) devices and networks
- Wireless broadband systems
- Machine-to-machine (M2M) communications
- Smart city infrastructure
Problems Solved
The patent application addresses the following problems in wireless communications:
- Efficient utilization of system bandwidth by using partial bands for channel state information reporting.
- Simplifying the configuration process for channel state information reporting by providing a configuration message from the base station.

Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration message from a base station, and the configuration message may include an indication of one or more partial bands for channel state information reporting. Each partial band of the one or more partial bands may be less than a system bandwidth and include a plurality of frequency domain units associated with a precoder. The UE may select one or more antenna ports for each partial band of the one or more partial bands based on the configuration message and calculate channel state information including a linear combination of the selected one or more antenna ports for each partial band. The UE may transmit the channel state information including an indication of the selected antenna ports and linear combination coefficients for each partial band of the one or more partial bands
