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:
Systems and methods are described for managing communications of an access node and a relay node. A utilization of a first frequency band that is used for communication between a relay node and wireless devices may be monitored. The relay node may also communicate with an access node to connect to a network. It may be determined that the monitored utilization meets a utilization criteria. One of a second frequency band and a third frequency band may be selected for the relay node based on the determination that the monitored utilization meets the utilization criteria. The selected frequency band may be allocated for communication between the relay node and wireless devices.
Abstract:
In operation, it is determined that a wireless device is in communication with a first access node using a first frequency band, and that a first coverage area of the first access node includes at least a portion of a second coverage area of a second access node. A coverage proportion of the first coverage area which includes the portion of the second coverage area of the second access node is calculated, and based on the coverage proportion a scan interval is determined. In addition, based on the determined scan interval and an application requirement of an application running on the wireless device, a signal level criteria is determined. When a signal level of the first frequency band meets the signal level criteria the wireless device is instructed to scan for a second frequency band of the second access node using the scan interval.
Abstract:
In systems and methods of managing frequency band selection for a wireless device, a first signal level of a first frequency band and a second signal level of a second frequency band received at a wireless device are monitored, wherein the first frequency band comprises a lower frequency band than the second frequency band. A first signal level difference is determined between the first signal level and the second signal level, and the wireless device is instructed to communicate with the access node over the second frequency band when the first signal level difference meets a first signal level difference criteria based on a decrease of the second signal level.
Abstract:
Systems and methods of providing wireless communication to a wireless device are provided. An access node of a first network associated with a first radio access technology can receive a request to establish a communication link with a first wireless device. The first wireless device can be in further communication with a second network associated with a second radio access technology different from the first radio access technology. The access node can determine that a number of second wireless devices in communication with the access node meets a threshold. When the number of second wireless devices exceeds the threshold, the access node can determine a subscription parameter based on a bandwidth allocation among the number of second wireless devices in communication with the access node. When the subscription parameter meets a criteria, the communication link can be established with the first wireless device.

It can be determined at a network node that a performance parameter of an access node meets a performance threshold. A profile of a wireless device in communication with the access node can be determined where the profile comprises an acceptable offloading condition. A plurality of offloading mechanisms can be identified based on the performance parameter and the acceptable offloading condition. An estimated change in the performance parameter can be determined for each combination of one of the plurality of offloading mechanisms and the acceptable offloading condition. An offloading mechanism can be selected based on the estimated change in the performance parameter and the acceptable offloading condition. The wireless device can be instructed to establish communication with the wireless communication system using the selected offloading mechanism.
Abstract:
Systems and methods for allocating a frequency band in a wireless communication network are provided. An access node can transmit a first system information message. The first system information message can include a first service identifier associated with a first service and a second service identifier associated with a second service to indicate availability of the first service and the second service over a frequency band. The access node can receive instructions to discontinue transmitting the second service identifier within the first system information message. The access node can transmit a second system information message after receiving instructions to discontinue transmitting the second service identifier. The second system information message can include only the first identifier to indicate availability of only the first service over the frequency band.

When the higher frequency band signal strength criteria meets the secpmd threshold and the determined modulation and coding scheme meets a third threshold, the wireless device is instructed to change from operating on the higher frequency band to operating on the lower frequency band.
