Antenna Selection Scheme Based on Information Bits: Patent Analysis

Strategic Insights -

The World Intellectual Property Organization (WIPO) has published a patent titled "ANTENNA SELECTION SCHEME BASED ON INFORMATION BITS" with the publication number WO/2011/132136 on October 27. This invention, filed by Telefonaktiebolaget L M Ericsson (PUBL) on April 18, 2011, under the application number PCT/IB2011/051678, presents a method for communicating a transport block of information bits from a transmitter node to a receiver node. The method involves encoding the information bits, dividing them into antenna selection bits and modulation bits, and using the antenna selection bits to select a transmit antenna from a plurality of antennas.

Key Takeaways:

  • The invention proposes a method for transmitting information bits by encoding and dividing them into antenna selection bits and modulation bits.
  • The antenna selection bits are used to select a transmit antenna, while the modulation bits are used by a modulator to select modulation symbols for transmission.
  • The receiver node receives a radio signal and computes a plurality of combined signals, each corresponding to one hypothesized transmit antenna.
  • The soft values for the antenna selection and modulation bits are combined and decoded to produce decision bits for recovering the transport block.
  • The invention targets applications where multiple antennas are available for transmission, such as wireless communication systems.
  • The method aims to improve the efficiency of antenna selection and reduce errors in decoding the transmitted information bits.
  • The transmitter node and receiver node are designed to work together to achieve efficient communication.

Statistics:

  • The patent was published on October 27, 2011, with the publication number WO/2011/132136.
  • The application number is PCT/IB2011/051678, and the filing date is April 18, 2011.
  • The invention is applicable to wireless communication systems where multiple transmit antennas are available.
  • The method aims to increase the accuracy of received information bits by reducing errors caused by antenna selection.
