OFDM SYMBOL ADJUSTMENT FOR SIDELINK TRANSMISSIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17929253 titled 'OFDM SYMBOL ADJUSTMENT FOR SIDELINK TRANSMISSIONS

Simplified Explanation

The patent application describes methods and apparatuses for adjusting the symbols used in sidelink transmissions in a wireless communication system using orthogonal frequency division multiplexing (OFDM). The method involves receiving information about the cyclic prefix (CP) extension in the sidelink control information (SCI) format. Based on this information, parameters (C and Δ) are determined, and a duration for the CP extension is calculated. The sidelink OFDM symbol is then extended for the calculated duration and transmitted.

  • The patent application focuses on adjusting OFDM symbols for sidelink transmissions in a wireless communication system.
  • The method involves receiving information about the CP extension in the SCI format.
  • Parameters (C and Δ) are determined based on the CP extension information.
  • The duration for the CP extension is calculated using the determined parameters.
  • The sidelink OFDM symbol is extended for the calculated duration.
  • The extended sidelink OFDM symbol is then transmitted.

Potential Applications

  • This technology can be applied in wireless communication systems that use OFDM for sidelink transmissions.
  • It can be used in various wireless communication devices, such as user equipment (UE), to improve the efficiency and reliability of sidelink transmissions.

Problems Solved

  • The technology solves the problem of adjusting OFDM symbols for sidelink transmissions in a wireless communication system.
  • It addresses the need for accurate determination of the CP extension duration based on the information provided in the SCI format.

Benefits

  • The technology improves the performance of sidelink transmissions by adjusting the OFDM symbols.
  • It allows for more efficient use of the wireless communication system by extending the CP duration as needed.
  • The method ensures accurate determination of the CP extension duration, leading to improved reliability and reduced interference in sidelink transmissions.


Original Abstract Submitted

Methods and apparatuses for orthogonal frequency division multiplexing (OFDM) symbol adjustment for sidelink (SL) transmissions in a wireless communication system. A method of user equipment (UE) includes receiving a sidelink control information (SCI) format that includes information on a cyclic prefix (CP) extension, determining parameters (Cand Δ) based on the information on the CP extension, and determining a duration for the CP extension based on the parameters. The method further includes extending a sidelink OFDM symbol for an interval preceding the sidelink OFDM symbol for the duration for the CP extension and transmitting the sidelink OFDM symbol with the extended CP duration.
