A system and method of providing wireless communications to a wireless device is provided. A scanning report can be received from each of a plurality of wireless devices in communication with a first access node using a first radio access technology. A second access node can be selected from among one or more second access nodes to initiate communications with the first access node over a communication link based on the scanning report from each of the plurality of wireless devices. The plurality of wireless devices can be instructed to establish communications with the second access node using a second radio access technology different from the first radio access technology. A bandwidth allocation of the communication link can be adjusted based on the plurality of wireless devices.

A system and method of scheduling communication in a wireless communication network are provided. An access node can receive an uplink scheduling request. The access node can communicate with a wireless device over a first and second frequency band. The access node can determine an interference indicator associated with the wireless device. The access node can determine a first scheduling scheme for the first frequency band and a second scheduling scheme for the second frequency band based on the uplink request and the interference indicator. The first scheduling scheme can comprise a first uplink portion and the second scheduling scheme can comprise a second uplink portion. The first uplink portion does not overlap the second uplink portion. The wireless device can be instructed to communicate uplink data to the access node during the first uplink portion and uplink data to the access node during the section uplink portion.

Method of scheduling communication in a wireless communication network

A system and method of allocating communication resources to a wireless device in a wireless communication network are provided. A first subframe configuration can be assigned to a first carrier of a frequency band of an access node. A second subframe configuration different from the first subframe configuration can be assigned to a second carrier of the frequency band. The access node can receive a resource request associated with an application running on the wireless device. An application requirement of the application running on the wireless device can be determined. The wireless device can be instructed to establish communication with the access node over one of the first carrier and the second carrier during a communication session based on the determined application requirement.

Method of allocating communication resources to a wireless device in a wireless communication network

In systems and methods of determining the availability of a radio access technology, a first message is received from a wireless device in communication with an access node using a first radio access technology, wherein the first message comprises a request of the availability of a second radio access technology at the access node. Based on the first message, an identifier of the wireless device and an identifier of the first access node are determined. Based on the access node identifier, it is identified whether the second radio access technology is available at the access node, and a second message is sent to the wireless device instructing the wireless device to scan for the second radio access technology when it is available.

Determining the availability of a radio access technology

In systems and methods of allocating carriers in a wireless communication network, a plurality of wireless devices in communication with an access node is ranked in a first ranking according to a required data rate of each wireless device. A carrier metric is determined for each of a plurality of carriers of the access node according to an actual data rate of each of the carriers and the required data rate of each wireless device, and each of the carriers is ranked in a second ranking for each of the plurality of wireless devices according to the determined carrier metric of each of the plurality of carriers. A first wireless device is selected from the first ranking, and a carrier from the second ranking is allocated to the selected first wireless device when the carrier provides the required data rate of the selected first wireless device.

Allocating carriers in a wireless communication system

In systems and methods of wireless device communication using carrier priority, it is determined for a wireless device using a lower priority carrier that a signal strength of a higher priority carrier meets a signal strength criteria. It is further determined that a loading of the higher priority carrier meets a loading criteria. When the loading meets the loading criteria and the signal strength meets the signal strength criteria, a handover is performed of the wireless device from the lower priority carrier to the higher priority carrier.

Wireless device communication using carrier priority

A system and method of scheduling communication in a wireless communication network are provided. A first access node can receive an uplink scheduling request from a wireless device. The first access node can receive a first interference indicator from a second access node when the wireless device is located at the cell edge. A first scheduling scheme for the first access node and a second scheduling scheme for the second access node can be determined based on the uplink scheduling request and the interference indicator. The uplink portions of the first scheduling scheme do not overlap the uplink portions of the second scheduling scheme. The first access node can instruct the wireless device to communicate uplink data to the first access node during the uplink portions of the first scheduling scheme and to communicate uplink data to the second access node during the uplink portions of the second scheduling scheme.

In systems and methods of mitigating L-band signal interference in a wireless communication system, it is determined that an aggregate power level of a plurality of wireless devices using an L-band carrier in communication with an access node meets a power level threshold. A probability of successful handover to a second carrier for each of the wireless devices is determined. At least one of the wireless devices is selected based on the determined probability of successful handover and a transmit power metric of the wireless device, and the selected at least one wireless device can be handed over to the second carrier.

A method, system, and medium are provided for assigning wireless-network technologies to base stations within a base station cluster. A first set of base stations is associated to form a first base station cluster. Once associated into the base station cluster, the total estimated demand on each wireless-network technology is determined for each of the base stations in the cluster. The technology having the highest total estimated demand is also determined for each of the base stations in the cluster. A first RF channel in the cluster is assigned the technology for which the majority of the base stations in the cluster have the highest total estimated demand. This process is carried out for the remaining RF channels in the cluster.
