CHANNEL ESTIMATION FOR MULTIPLE RADIO ACCESS TECHNOLOGIES IN A HIGH SPEED SCENARIO - A simplified explanation of the abstract

This abstract first appeared for US patent application 18258933 titled 'CHANNEL ESTIMATION FOR MULTIPLE RADIO ACCESS TECHNOLOGIES IN A HIGH SPEED SCENARIO

Simplified Explanation

Methods, systems, and devices for wireless communications are described in this patent application. The techniques described enable a user equipment (UE) to use information obtained via a radio access technology (RAT), such as Long Term Evolution (LTE), to support communications in another RAT, such as New Radio (NR).

  • The UE receives an indication of a high speed associated with its wireless connection to a first base station operating according to a first radio access technology.
  • The UE performs a channel estimation procedure for the first wireless connection and generates a Doppler value based on the received indication.
  • The UE applies the generated Doppler value to a frequency tracking loop or a time tracking loop for communications with a second base station via a second wireless connection.
  • The second base station operates according to a second RAT.

Potential applications of this technology:

  • Improved wireless communication between different radio access technologies.
  • Seamless handover between different RATs for uninterrupted connectivity.
  • Enhanced performance and reliability of wireless connections.

Problems solved by this technology:

  • Overcoming the limitations of using different RATs for wireless communications.
  • Addressing the challenges of maintaining a stable connection when switching between different RATs.
  • Improving the accuracy of frequency and time tracking in wireless communications.

Benefits of this technology:

  • Enhanced user experience with improved wireless connectivity.
  • Increased efficiency and reliability of wireless communications.
  • Facilitates the integration of different RATs in wireless networks.


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) using information identified via radio access technology (RAT) (e.g., Long Term Evolution (LTE)) to support communications in another RAT (e.g., New Radio (NR)). For example, the UE may receive, from a first base station operating according to a first radio access technology an indication of a high speed associated with a first wireless connection of the UE with the first base station. The UE may perform a channel estimation procedure for the first wireless connection to generate a Doppler value based on receiving the indication. The UE may apply the generated Doppler value to a frequency tracking loop or a time tracking loop for communications with a second base station via a second wireless connection, wherein the second base station is operating according to a second RAT.
