ADAPTIVE PDSCH AND DMRS PATTERN FOR HST DEPLOYMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18020415 titled 'ADAPTIVE PDSCH AND DMRS PATTERN FOR HST DEPLOYMENT

Simplified Explanation

Methods, computer program products, and apparatuses for adaptive PDSCH (Physical Downlink Shared Channel) and DMRS (Demodulation Reference Signal) pattern are disclosed in this patent application. The method involves receiving a frequency shift estimate from a User Equipment (UE), where the frequency shift estimate includes one or more frequency offsets corresponding to one or more Transmit-Receive Points (TRPs). Based on the frequency shift estimate, at least one DMRS pattern is selected from a plurality of DMRS patterns. The selected DMRS pattern includes multiple DMRS symbols and is associated with a frame structure that includes multiple slots in a subframe. An indication of the selected DMRS pattern is then transmitted to the UE.

  • The patent application describes a method for adapting PDSCH and DMRS patterns based on frequency shift estimates received from a UE.
  • The method involves selecting a DMRS pattern from a plurality of patterns based on the frequency shift estimate.
  • The selected DMRS pattern includes multiple DMRS symbols and is associated with a frame structure that includes multiple slots in a subframe.
  • An indication of the selected DMRS pattern is transmitted to the UE.

Potential applications of this technology:

  • This technology can be applied in wireless communication systems, particularly in the downlink transmission of data from a base station to a UE.
  • It can improve the efficiency and reliability of communication by adapting the PDSCH and DMRS patterns based on frequency shift estimates.

Problems solved by this technology:

  • Frequency shifts can occur in wireless communication systems due to various factors, such as Doppler effects or synchronization errors.
  • These frequency shifts can cause degradation in the performance of PDSCH and DMRS patterns, leading to reduced data transmission rates and increased errors.
  • The disclosed method solves this problem by adapting the PDSCH and DMRS patterns based on the frequency shift estimates, ensuring optimal performance even in the presence of frequency shifts.

Benefits of this technology:

  • By adapting the PDSCH and DMRS patterns, this technology can improve the overall data transmission rates and reliability in wireless communication systems.
  • It allows for efficient utilization of available resources by selecting the most suitable DMRS pattern based on the frequency shift estimate.
  • The adaptive nature of this technology ensures that the communication system can dynamically adjust to changing conditions, providing optimal performance in various scenarios.
