Document Type and Number:
WIPO Patent Application WO/2021/068158
Kind Code:
A1
Abstract:
The present disclosure relates to methods and apparatuses. According to some embodiments of the disclosure, a method performed by a communication device, includes: receiving, from a base station, a first configuration information indicating a threshold to configure the communication device, wherein the threshold is associated with data volume; determining whether congestion happens at the communication device based on the threshold; and transmitting a congestion indication to a first parent node via a Backhaul Adaptation Protocol (BAP) signaling message when it is determined that the congestion happens at the communication device.
