Abstract
Systems, methods, and processing nodes for performing carrier aggregation in a wireless network including obtaining, at a relay access node, a control channel load level of a first carrier deployed by a donor access node, determining, at the relay access node, that the control channel load level is within an acceptable load level, and aggregating the first carrier with a second carrier deployed by the relay access node to communicate with a wireless device attached to the relay access node.
Claims16
A system for performing carrier aggregation in a wireless network, the system comprising:
- a first access node configured to deploy one or more carriers of a first type;
- a second access node communicably coupled to the first access node, the second access node being configured to deploy one or more carriers of a second type;
- and
- a processing node communicably coupled to both first and second access nodes, the processing node being configured to perform operations comprising:
- identifying a wireless device attached to the second access node that can communicate via two or more aggregated carriers;
- instructing the first access node to:
- identify a first carrier from among the one or more carriers of the first type that has a load level of its associated control channel that is below a threshold load level;
- and
- transmit, to the second access node, load information of the first carrier, wherein the load information indicates to the second access node that the load level of the associated control channel is below the threshold load level;
- and
- instructing the second access node to:
- aggregate the first carrier with a second carrier from among the one or more carriers of the second type, and
- communicate with the wireless device using the aggregated first and second carriers.
A method for performing carrier aggregation in a wireless network, the method comprising:
- obtaining, at a donor access node, a control channel load level of a first carrier deployed by the donor access node;
- determining, at the donor access node, that the control channel load level is within an acceptable load level;
- transmitting, by the donor access node, load information of the first carrier to a relay access node communicatively coupled to the donor access node, the load information indicating to the relay access node that the control channel load level is within the acceptable load level;
- and
- aggregating, at the relay access node, the first carrier with a second carrier deployed by the relay access node to communicate with a wireless device attached to the relay access node.
A processing node for performing carrier aggregation in a wireless network, the processing node comprising a processor and a memory that are configured to perform operations comprising:
- obtaining a load information associated with a plurality of frequency sub-bands deployed by one or more access nodes, wherein the load information indicates an availability of resources within a control channel associated with each of the plurality of frequency sub-bands;
- determining that the availability of resources for a first control channel associated with a first frequency sub-band is higher than for any other control channel associated with the plurality of frequency sub-bands;
- and
- transmitting the load information to a second access node in communication with the first access node, wherein the load information indicates to the second access node that the availability of resources for the first control channel is higher than for any other control channel,
- wherein the second access node aggregates the first frequency sub-band with a second frequency sub-band deployed by the second access node.
