CHANNEL QUALITY INDICATOR REPORTING ACROSS MULTIPLE SUBBANDS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17382828 titled 'CHANNEL QUALITY INDICATOR REPORTING ACROSS MULTIPLE SUBBANDS

Simplified Explanation

Methods, systems, and devices for wireless communications are described in this patent application. The focus is on supporting group channel quality indicator (CQI) reporting in a wireless communications system. Here's a simplified explanation of the abstract:

  • A user equipment (UE) receives signaling from a base station indicating a group of component carriers (CCs) and one or more subbands within the group of CCs.
  • The UE receives one or more reference signals within the subbands and uses them to determine a group CQI index for the group of CCs.
  • The UE then transmits a report to the base station, indicating the group CQI index.
  • The base station uses the group CQI index to determine a CQI index for each of the subbands.

Potential applications of this technology:

  • Wireless communication systems that support group CQI reporting.
  • Enhancing the efficiency and performance of wireless networks by providing accurate CQI information for different subbands.
  • Improving resource allocation and scheduling in wireless networks based on the CQI index.

Problems solved by this technology:

  • In wireless communication systems, it is important to have accurate information about the quality of the communication channels.
  • Traditional CQI reporting methods may not provide sufficient granularity or accuracy when dealing with multiple component carriers and subbands.
  • This technology solves the problem by introducing group CQI reporting, allowing for more efficient and accurate assessment of channel quality.

Benefits of this technology:

  • Improved performance and efficiency of wireless networks by providing more accurate CQI information.
  • Better resource allocation and scheduling based on the CQI index for each subband.
  • Enhanced user experience through optimized wireless communication quality.


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. In some examples, a wireless communications system may support group channel quality indicator (CQI) reporting. For example, a user equipment (UE) may receive, from a base station, signaling indicating a group of component carriers (CCs) and one or more subbands within the group of CCs. The UE may receive one or more reference signals within the one or more subbands and determine a group CQI index corresponding to the group of CCs based at least in part on the one or more reference signals. The UE may then transmit a report to the base station indicating the group CQI index and the base station may determine a CQI index for each of the one or more subbands based on the group CQI index.
