COMMUNICATION METHOD APPLIED TO INTEGRATED ACCESS AND BACKHAUL IAB SYSTEM AND COMMUNICATION APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18156560 titled 'COMMUNICATION METHOD APPLIED TO INTEGRATED ACCESS AND BACKHAUL IAB SYSTEM AND COMMUNICATION APPARATUS

Simplified Explanation

The abstract describes a communication method for an integrated access and backhaul (IAB) system. Here is a simplified explanation of the abstract:

  • The communication method involves a child node receiving a message from an access network device through a parent node.
  • The message received by the child node is a radio resource control (RRC) reconfiguration message, which includes an indication for random access-free.
  • Upon receiving the message, the child node starts a timer.
  • The child node then sends a response message, called RRC reconfiguration complete, back to the access network device through the parent node.
  • The child node receives indication information from the parent node, which instructs the child node to stop the timer.
  • Finally, the child node stops the timer based on the received indication information.

Potential applications of this technology:

  • Integrated access and backhaul (IAB) systems in wireless communication networks.
  • Communication methods for improving efficiency and reliability in wireless networks.

Problems solved by this technology:

  • Efficient communication between access network devices and child nodes in an IAB system.
  • Ensuring reliable transmission of messages and synchronization between nodes.

Benefits of this technology:

  • Improved communication efficiency and reliability in integrated access and backhaul systems.
  • Enhanced synchronization and coordination between access network devices and child nodes.
  • Optimal utilization of radio resources in wireless networks.


Original Abstract Submitted

A communication method applied to an integrated access and backhaul (IAB) system includes: a child node receives a first radio resource control (RRC) reconfiguration message from an access network device via a parent node, where the first RRC reconfiguration message includes a random access-free indication. The child node starts a timer. The child node sends a first RRC reconfiguration complete message to the access network device via the parent node. The child node receives first indication information from the parent node, where the first indication information indicates to stop the timer. The child node stops the timer.
