Strategic Insights -

The World Intellectual Property Organization has published patent application number WO/2011/137854, titled "INDICATION METHOD FOR REPOTING CHANNEL STATE INFORMATION, METHOD FOR REPOTING CHANNEL STATE INFORMATION, SERVICE STATION POINT AND TERMINAL" on November 10. The invention, filed by Huawei Technologies Co., Ltd. on May 31, 2011, under Application No. PCT/CN2011/075035, provides an indication method for reporting channel state information in a Time Division Duplexing (TDD) system. According to the abstract, the method involves grouping component carriers, scheduling and distributing uplink sub-frames, and indicating the sub-frames to terminals, which then report channel state information in corresponding sub-frames.

Key Takeaways:

  • The patent application proposes a method for reporting channel state information in a TDD system, which includes grouping component carriers and distributing uplink sub-frames.
  • The indication method involves a service station point with a grouping module, scheduling module, and distribution module, which groups component carriers and distributes uplink sub-frames.
  • The terminal, which includes a configuration module and a report module, acquires the indication from the service station point and reports channel state information in corresponding uplink sub-frames.
  • The method can be applied to TDD systems, and the patent was filed on May 31, 2011, under Application No. PCT/CN2011/075035.
  • The patent application provides a solution for reporting channel state information in TDD systems, enabling more efficient data transmission and reception.
