RANDOM ACCESS METHOD AND APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18352328 titled 'RANDOM ACCESS METHOD AND APPARATUS

Simplified Explanation

This patent application describes a method and apparatus for random access in a communication system.

  • The method involves a terminal device determining a random access opportunity and a random access preamble based on a measurement result of a synchronization signal/physical broadcast channel block.
  • The terminal device then sends a random access signal using the determined random access opportunity and random access preamble.
  • The random access opportunity and/or random access preamble are associated with a data subcarrier spacing Δf and/or a ratio Δf/Δf of a random access subcarrier spacing Δf to the data subcarrier spacing Δf.
  • The random access subcarrier spacing Δf and the data subcarrier spacing Δf are both greater than 120 kHz.
  • The innovation aims to improve communication performance by designing a random access signal based on a large subcarrier spacing.


Original Abstract Submitted

This application discloses a random access method and a corresponding apparatus. The method includes: A terminal device determines, based on a measurement result of a SS/PBCH block, a random access opportunity and a random access preamble that are associated with the synchronization signal/physical broadcast channel block. The terminal device sends a random access signal based on the random access opportunity and the random access preamble. There is a correspondence between the random access opportunity and/or the random access preamble and at least one of the following: a data subcarrier spacing Δf, or a ratio Δf/Δfof a random access subcarrier spacing Δfto the data subcarrier spacing Δf. At least one of the random access subcarrier spacing Δfand the data subcarrier spacing Δfis greater than 120 kHz. This application provides a design of a random access signal based on a large subcarrier spacing, to improve communication performance.
