ENCODING FOR UPLINK CHANNEL REPETITION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17449789 titled 'ENCODING FOR UPLINK CHANNEL REPETITION

Simplified Explanation

A patent application describes a method for encoding and decoding partial uplink (UL) repetitions in a wireless communication system. Here is a simplified explanation of the abstract:

  • The user equipment (UE) in a wireless communication system can encode partial UL repetitions using a sequence-based encoding technique.
  • The encoding is based on a codebook, which is a predefined set of codes.
  • The first partial UL repetition does not include a demodulation reference signal (DM-RS), which is a signal used for demodulation at the receiver.
  • The base station transmits the configuration of the encoding scheme to the UE.
  • The UE uses the received configuration to encode the partial UL repetitions.
  • The base station then decodes the received partial UL repetitions based on the configuration.

Potential applications of this technology:

  • This technology can be used in various wireless communication systems, such as 5G and beyond, to improve the efficiency and reliability of uplink transmissions.
  • It can be applied in scenarios where partial UL repetitions are used, such as in massive machine-type communications (mMTC) or ultra-reliable low-latency communications (URLLC).

Problems solved by this technology:

  • By using sequence-based encoding and excluding the DM-RS in the first partial UL repetition, this technology can reduce the complexity and overhead of the encoding process.
  • It allows for more efficient use of radio resources and improves the overall performance of the wireless communication system.

Benefits of this technology:

  • Improved efficiency: The sequence-based encoding and exclusion of DM-RS in the first partial UL repetition result in more efficient use of resources and improved overall system performance.
  • Reduced complexity: By simplifying the encoding process, this technology reduces the computational complexity at the UE and base station.
  • Enhanced reliability: The use of a codebook and configuration transmission ensures accurate decoding of the partial UL repetitions, leading to enhanced reliability in the wireless communication system.


Original Abstract Submitted

A user equipment (UE) may be configured to encode at least one partial uplink (UL) repetition using a sequence-based encoding based on a codebook, the first partial UL repetition not including a demodulation reference signal (DM-RS). A base station may transmit a configuration of the encoding scheme of the partial UL repetitions to the UE, and the UE may encode the at least one partial UL repetition based on the received configuration. The base station may decode the received at least one partial UL repetition based on the configuration.
