REFERENCE SIGNAL FOR SKIPPED PDSCH - A simplified explanation of the abstract

This abstract first appeared for US patent application 17449792 titled 'REFERENCE SIGNAL FOR SKIPPED PDSCH

Simplified Explanation

A base station can configure a new demodulation reference signal (DM-RS) to indicate a skipped semi-persistent scheduled (SPS) physical downlink shared channel (PDSCH) occasion to a user equipment (UE). The UE can detect a discontinuous transmission (DTX) in the skipped SPS PDSCH occasion by receiving the new DM-RS within the corresponding PDSCH occasion. The UE can measure the energy of the PDSCH signal symbols to determine if the PDSCH signal symbols contain data or not, thus identifying the skipped SPS PDSCH occasion. The UE can also measure the DM-RS energy or detect the configuration of the DM-RS to determine if the second PDSCH includes a PDSCH signal.

  • A base station configures a new demodulation reference signal (DM-RS) to indicate a skipped semi-persistent scheduled (SPS) physical downlink shared channel (PDSCH) occasion to a user equipment (UE).
  • The UE detects a discontinuous transmission (DTX) in the skipped SPS PDSCH occasion by receiving the new DM-RS within the corresponding PDSCH occasion.
  • The UE measures the energy of the PDSCH signal symbols to determine if the PDSCH signal symbols contain data or not, identifying the skipped SPS PDSCH occasion.
  • The UE measures the DM-RS energy or detects the configuration of the DM-RS to determine if the second PDSCH includes a PDSCH signal.

Potential Applications

  • This technology can be applied in wireless communication systems using LTE or 5G networks.
  • It can improve the efficiency and reliability of data transmission between base stations and user equipment.
  • The technology can be used in various industries that rely on wireless communication, such as telecommunications, IoT, and autonomous vehicles.

Problems Solved

  • The technology solves the problem of detecting and handling skipped semi-persistent scheduled (SPS) physical downlink shared channel (PDSCH) occasions in wireless communication systems.
  • It allows user equipment (UE) to identify and handle discontinuous transmission (DTX) in the skipped SPS PDSCH occasions, ensuring reliable data transmission.

Benefits

  • Improved efficiency: The technology enables more efficient use of resources by indicating skipped SPS PDSCH occasions and detecting discontinuous transmission.
  • Enhanced reliability: By accurately detecting and handling skipped SPS PDSCH occasions, the technology improves the reliability of data transmission in wireless communication systems.
  • Simplified implementation: The measurement of energy and configuration of demodulation reference signals (DM-RS) provides a straightforward method for identifying skipped SPS PDSCH occasions and detecting the presence of PDSCH signals.


Original Abstract Submitted

A base station may configure a new demodulation reference signal (DM-RS) to indicate a skipped semi-persistent scheduled (SPS) physical downlink shared channel (PDSCH) occasion to a user equipment (UE), and the UE may detect a discontinuous transmission (DTX) in the skipped SPS PDSCH occasion based on receiving the new DM-RS within the corresponding PDSCH occasion. The UE may detect that the corresponding PDSCH occasion is a skipped SPS PDSCH occasion by measuring the energy of the PDSCH signal symbols to detect that the PDSCH signal symbols do not include data signal. The UE may measure the DM-RS energy or detect the configuration of the DM-RS to determine that the second PDSCH does not include a PDSCH signal.
