Method and Apparatus for Traffic Management in a Self-Backhauled Network by Using Capacity Grants

A radio base station for integrated access and backhaul, the radio base station being configured to allocate a first part of its capacity to access traffic and a second part of its capacity to backhaul traffic;

• and the radio base station being further configured to form a self-backhauled network with a plurality of other radio base stations thus allowing each radio base station to be connected to the core network via the self-backhauled network;
• the radio base station comprising:
• a receiver configured to receive incoming capacity grants from adjacent radio base stations in the self-backhauled network, the incoming capacity grants indicating the capacity granted for backhaul traffic via the respective adjacent radio base station;
• a routing circuit configured to select a backhaul route based on the incoming capacity grants;
• and
• a transmitter configured to transmit the backhaul traffic to an adjacent radio base station in accordance with the selected backhaul route.

A method in a radio base station, the radio base station configured to allocate a first part of its capacity to access traffic and a second part of its capacity to backhaul traffic;

• the radio base station further configured to form a self-backhauled network with a plurality of other radio base stations thus allowing each radio base station to be connected to the core network via the self-backhauled network, the method comprising the radio base station:
• receiving incoming backhaul capacity grants from adjacent radio base stations in the self-backhauled network, the incoming capacity grants indicating the capacity granted for backhaul traffic via the respective adjacent radio base stations;
• selecting a backhaul route for the outgoing backhaul traffic of the radio base station based on the incoming backhaul grants;
• transmitting the outgoing backhaul traffic in accordance with the selected backhaul route.
