Abstract
Optimizing carrier aggregation assignment for relay nodes by assigning all available component carriers within a sector towards relay node transmissions regardless of a buffer status of the relay nodes. Embodiments include stationary relay nodes and those with consistent channel states.
Claims20
A method for assigning component carriers for relay nodes, the method comprising:
- identifying a relay node accessing network services from a donor access node, the donor access node deploying a plurality of component carriers;
- determining that channel state information is consistent over a time period;
- based on determining that the channel state information is consistent over a time period, determining all available component carriers of the plurality of component carriers to avoid delays or failures in setting up the plurality of component carriers;
- and
- assigning all available component carriers towards data transmission between the relay node and the donor access node to provide continuous resources to a backhaul link of the relay nodes.

A system for assigning component carriers for relay nodes, the system comprising:
- a processing node;
- and
- a processor coupled to the processing node, the processor configured to perform operations comprising:
- receiving an attach request from a relay node at a donor access node, the donor access node being configured to deploy a plurality of component carriers;
- determining that channel state information is consistent over a time period;
- based on determining that the channel state information is consistent over a time period, determining all available component carriers of the plurality of component carriers to avoid delays or failures in setting up the plurality of component carriers;
- and
- assigning all available component carriers towards data transmission between the relay node and the donor access node by default to provide continuous resources to a backhaul link of the relay nodes.

A processing node for assigning component carriers for relay nodes, the processing node comprising:
- one or more processors being operably coupled to one or more relay nodes and one or more donor access nodes, the one or more processors configured to perform operations comprising:
- initiating a connection between a relay node of the one or more relay nodes and a donor access node of the one or more donor access nodes, the donor access node being configured to deploy a plurality of component carriers;
- determining that channel state information is consistent over a time period;
- based on determining that the channel state information is consistent over a time period, determining all available component carriers of the plurality of component carriers to avoid delays or failures in setting up the plurality of component carriers;
- assigning all available component carriers towards the relay node by default to provide continuous resources to a backhaul link of the relay nodes;
- and
- incrementally reducing a quantity of component carriers of the available component carriers based on a load level of the donor access node exceeding different thresholds.
