US 2025/0063466 A1 · METHOD AND DEVICE FOR ROUTING DATA PACKET, AND METHOD AND DEVICE FOR CONTROLLING DATA PACKET TRANSMISSION

Abstract

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The embodiments of the present application provide a method and a device for routing a data packet, and a method and a device for controlling a data packet transmission. The data packet routing method includes: receiving a first message transmitted by a first node; and determining a transmission path of the data packet according to the first message. The method provided in the present application achieves that a node in a relay network can determine a condition for transmitting the data packet by using other transmission paths, thereby effectively using multiple transmission paths to implement the data packet transmission.

Dependent claims

A method performed by a first integrated access and backhaul (IAB) node in a multi-hop network, the method comprising:

transmitting, to a central unit (CU) of a donor node, a first message including IAB congestion related information;
and
transmitting, to a second IAB node, a second message including backhaul (BH) radio link failure (RLF) detection indication,
wherein the IAB congestion related information includes an identifier of a BH radio link control (RLC).
