US 10,455,627 B2 · Data transmission link establishment apparatus and method, and communications system

Abstract

This application provides a data transmission link establishment apparatus. The apparatus includes: a selection unit, configured to select a target node; a determining unit, configured to determine a backhaul node that needs to establish a data transmission link with the target node selected by the selection unit; a setting unit, configured to set protocol stack roles, in the data transmission link, of the target node and the backhaul node that is determined by the determining unit; and a configuration unit, configured to perform configuration on the target node and the backhaul node according to the protocol stack roles that are set by the setting unit, to establish the data transmission link between the target node and the backhaul node.

Dependent claims

A data transmission link establishment apparatus, comprising:

a processor, configured to:
select a target node;
determine a backhaul node for establishing a data transmission link with the target node;
determine a data transmission direction between the target node and the backhaul node;
select a channel for data transmission between the target node and the backhaul node;
