Abstract
The present specification presents a method for synchronizing DU transmission timings of IAB nodes.
Claims19
A synchronization method for a distributed unit (DU) transmission timing performed by an integrated access and backhaul (IAB) node in a wireless communication system, the method comprising:
- transmitting a random access preamble to a parent node;
- receiving a random access response from the parent node;
- receiving a first parameter related to a mobile termination (MT) transmission timing of the IAB node and a second parameter related to the DU transmission timing of the IAB node from the parent node;
- determining a time spacing between an MT reception timing and the DU transmission timing of the IAB node based on the first parameter and the second parameter;
- and
- performing synchronization for the DU transmission timing with the parent node based on the time spacing.
3 more elements
A node comprising:
- one or more memories storing instructions;
- one or more transceivers;
- and
- one or more processors connecting the one or more memories with the one or more transceivers,
- wherein the one or more processors, by executing the instruction, are configured to perform:
- transmitting a random access preamble to a parent node;
- receiving a random access response from the parent node;
- receiving a first parameter related to a mobile termination (MT) transmission timing of an integrated access and backhaul (IAB) node and a second parameter related to a distributed unit (DU) transmission timing of the IAB node from the parent node;
- determining a time spacing between an MT reception timing and the DU transmission timing of the IAB node based on the first parameter and the second parameter;
- and
- performing synchronization for the DU transmission timing with the parent node based on the time spacing.
8 more elements
An apparatus configured to control an integrated access and backhaul (IAB) node, comprising:
