RACH TIMELINE INCORPORATING BANDWIDTH PART SWITCH TO RECEIVE A SYNCHRONIZATION SIGNAL BLOCK - A simplified explanation of the abstract

This abstract first appeared for US patent application 17934481 titled 'RACH TIMELINE INCORPORATING BANDWIDTH PART SWITCH TO RECEIVE A SYNCHRONIZATION SIGNAL BLOCK

Simplified Explanation

The patent application relates to wireless communications and specifically focuses on techniques for performing a random access channel (RACH) procedure. The method described in the patent application involves the following steps:

  • Detecting a synchronization signal block (SSB) transmitted in a specific bandwidth part (BWP).
  • Transmitting a number of first messages as part of a random access channel (RACH) procedure in a different BWP associated with the detected SSB.
  • Monitoring the second BWP for a second message sent in response to the first messages.
  • Switching back to the first BWP to monitor for SSBs if the second message is not received within a specific timeline after transmitting the first messages and certain conditions are met.

Potential applications of this technology include:

  • Improving the efficiency and reliability of wireless communication systems.
  • Enhancing the performance of random access channel (RACH) procedures in wireless networks.
  • Enabling faster and more accurate detection of synchronization signal blocks (SSBs).

Problems solved by this technology include:

  • Addressing issues related to the synchronization and timing of wireless communication systems.
  • Improving the success rate of random access channel (RACH) procedures.
  • Reducing the time and resources required for detecting and responding to synchronization signal blocks (SSBs).

Benefits of this technology include:

  • Increased reliability and accuracy in wireless communication systems.
  • Improved efficiency and speed in random access channel (RACH) procedures.
  • Enhanced overall performance and user experience in wireless networks.


Original Abstract Submitted

Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for performing a random access channel (RACH) procedure. According to one aspect, a method for wireless communication by a user equipment (UE), generally includes detecting at least a first synchronization signal block (SSB) transmitted in a first bandwidth part (BWP), transmitting, in a second BWP associated with the first SSB, a number of first messages as part of a random access channel (RACH) procedure, monitoring, in the second BWP, for a second message sent in response to the number of first messages, and switching back to the first BWP to monitor for SSBs, if the second message is not received within a first timeline after transmitting the number of first messages and one or more conditions are met.
