TECHNIQUES FOR CHANNEL MEASUREMENTS FOR MULTIPLE UPLINK CARRIERS IN CARRIER AGGREGATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17876335 titled 'TECHNIQUES FOR CHANNEL MEASUREMENTS FOR MULTIPLE UPLINK CARRIERS IN CARRIER AGGREGATION

Simplified Explanation

Methods, systems, and devices for wireless communications are described for channel measurements for multiple uplink carriers in carrier aggregation (CA). The patent application focuses on a specific configuration of CA, which includes a first downlink carrier, a first uplink carrier, and a second uplink carrier. The second uplink carrier is a supplemental uplink (SUL) carrier that does not have an associated downlink carrier in the same frequency band. The invention involves configuring a measurement downlink carrier and associating it with the second uplink carrier. Measurements of a reference resource of the measurement downlink carrier are then used to determine transmission parameters of the second uplink carrier.

  • The patent application describes methods, systems, and devices for channel measurements in carrier aggregation (CA) for multiple uplink carriers.
  • The CA configuration includes a first downlink carrier, a first uplink carrier, and a second uplink carrier.
  • The second uplink carrier is a supplemental uplink (SUL) carrier without an associated downlink carrier in the same frequency band.
  • A measurement downlink carrier is configured and associated with the second uplink carrier.
  • Measurements of a reference resource of the measurement downlink carrier are used to determine transmission parameters of the second uplink carrier.

Potential Applications:

  • This technology can be applied in wireless communication systems that utilize carrier aggregation (CA) for increased data rates and improved network capacity.
  • It can be used in 4G and 5G networks to enhance the performance of multiple uplink carriers.

Problems Solved:

  • The invention solves the problem of accurately measuring and determining transmission parameters for a second uplink carrier that does not have an associated downlink carrier in the same frequency band.
  • It addresses the challenge of effectively utilizing supplemental uplink (SUL) carriers in carrier aggregation (CA) configurations.

Benefits:

  • The technology enables more efficient utilization of multiple uplink carriers in carrier aggregation (CA) configurations.
  • It improves the accuracy of channel measurements and determination of transmission parameters for supplemental uplink (SUL) carriers.
  • The invention enhances the overall performance and capacity of wireless communication systems.


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described for channel measurements for multiple uplink carriers in carrier aggregation (CA). A CA configuration may provide a first downlink carrier, a first uplink carrier, and a second uplink carrier. The second uplink carrier may be a supplemental uplink (SUL) carrier that does not have an associated downlink carrier in a same frequency band. A measurement downlink carrier may be configured and associated with the second uplink carrier, and measurements of a reference resource of the measurement downlink carrier may be used to determine transmission parameters of the second uplink carrier.
