Abstract: A system and method of scheduling communication in a wireless communication network are provided. A scheduling scheme comprising a first and second subframe can be determined to communicate data between a first access node and first wireless devices, and a second access node and second wireless devices. A resource request from a network node can be received. An interference indication of the one of the first wireless devices can be determined after receiving the resource request. The first access node can be instructed to transmit data addressed to the one of the first wireless devices during the second subframe when the interference indication of the one of the first wireless devices meets an interference criteria. The second access node can be instructed to transmit data addressed to at least one of the second wireless devices that meets the signal condition threshold during the second subframe of the scheduling scheme.

Abstract: A system and method of scheduling communication in a wireless communication network are provided. An access node can determine a scheduling scheme based on an indication of data addressed to wireless devices. The scheduling scheme can comprise a first subframe and a second subframe comprising a first and second resource block. The scheduling scheme can be communicated. Data addressed to the wireless devices in communication with a first access node can be transmitted during the first subframe and the first resource block of the second subframe. A second access node can be instructed to assign data addressed to wireless devices that meet a signal condition threshold to be transmitted during the second resource block of the second subframe and to assign data addressed to wireless devices that do not meet the signal condition threshold to be transmitted during the first subframe and the first resource block of the second subframe.

Abstract: Multiple network resources are considered when distributing network load among access nodes. For example, traffic load, user load, and bearer load may all be considered in the decision to move a wireless device from one access node to another. An N-dimensional load vector is calculated where each of the N dimensions is associated with a network resource utilization factor. A load vector is calculated for each of the access nodes being considered for load balancing. The load vectors for access nodes under consideration for load balancing are subtracted to create a difference vector. When the magnitude of the difference vector is greater than a threshold, the communication system balances the load between the two access nodes.

Abstract: A control element of a first wireless communication network, such as a mobility management entity, determines that a wireless device is being served by a second wireless communication network. The control element also receives an indicator associated with the availability of a base station in the first wireless communication network to serve the wireless device. Based on the indicator, the control element initiates a handover of the wireless device from the second wireless communication network to the first wireless communication network. The control element may also initiates a handover of the wireless device based on the indicator and based on a signal strength reported by the wireless device.

Abstract: Systems and methods are described for scheduling wireless resources with coordinated multipoint transmissions. It may be determined that a signal level for a wireless device in communication with an access node does not meet a signal level criteria. Based on the determination, an access node may be instructed to transmit information to the wireless device using a coordinated multipoint transmission. A number of wireless devices in communication with the access node that comprise an application requirement that meets an application requirement criteria may further be determined. Then, the access node may be instructed to schedule wireless transmissions using at least one of semi-persistent scheduling and delay based scheduling based on the determined number of the plurality of wireless devices and the instruction to transmit using the coordinated multipoint transmission.

Abstract: Using a first access node, a set of wireless devices are communicated with using a first frame configuration. The communication using the first frame configuration meets a first throughput threshold criteria for both a first and second subsets of the wireless devices A second frame configuration having a second ratio of uplink subframes to downlink subframes is selected. Based on the selection of the second frame configuration, a second access node is used concurrently with the first access node to communicate with the second subset of wireless devices using the second frame configuration.

Abstract: Systems and methods are described for providing multiple voice service modes to a wireless device using data packet transmission through a wireless network. Application requirements including a signal level threshold for a wireless device may be determined. Signal level information for the wireless device may be received and transmitted among various network nodes. The received signal level may be compared with the signal level threshold for the wireless device. The wireless device and the access node may communicate wirelessly to provide voice services to the wireless device application. Data transmission may be converted between a first mode and a second mode depending upon a relative position of the received signal level with respect to the signal level threshold. The second mode of data transmission may be used where the first mode of data transmission cannot because the second mode may consume less network resources.
