Abstract: Systems and methods are described for coordinating interference mitigation techniques and beamforming. Information about transmissions made by at least one access node neighboring a first access node is obtained. Further, profile data for a wireless device within a transmission range of the first access node is obtained. The systems and methods contemplate determining that transmissions from the first access node to the wireless device will utilize beamforming, based upon the profile data for the wireless device. The first access node is instructed to schedule wireless transmissions to the wireless device utilizing beamforming, based upon the determination to use beamforming.

Abstract: Access nodes in a network are configured to periodically measure cell loads and exchange cell load measurements with neighbors. At each access node, cell loads are compared with load thresholds, and with neighboring loads, to determine whether or not load balancing operations should be triggered. Load balancing operations include reducing or increasing an effective coverage area of one or both of the congested cell and the neighbor cell by adjusting a handover threshold parameter, such as a threshold signal level. Adjusting thresholds at a congested cell triggers more handovers from the congested cell to the non-congested cell. Similarly, adjusting thresholds at a non-congested cell prevents handovers from the non-congested cell to the congested cell.

Abstract: Selecting a first BWP for a first carrier deployed by an access node based on requirements of wireless devices attached to the first carrier, selecting a second BWP for a second carrier deployed by the access node based on requirements of wireless devices attached to the second carrier, monitoring a MU-MIMO performance for each carrier, and performing handovers of wireless devices between the first and second carriers based on the MU-MIMO performance.

Abstract: Systems and methods are described for preventing premature processing during beam forming. It may be determined, at an access node, that a wireless device has received data using a beam formed transmission from the access node. A gap may be calculated between a reported signal level for the wireless device and a transmission scheme used to transmit downlink data to the wireless device. A threshold value may then be adjusted based on the calculated gap, where the threshold value is used to determine when the wireless device scans a plurality of frequency bands. The adjusted threshold value may be transmitted to the wireless device.

Abstract: A system information message is received by a wireless device. The system information message was broadcast from a first access node using a first frequency band. Cell loading information is extracted from the system information message. Based on the cell loading information, it is determined whether to connect the wireless device to the first access node using the first frequency band, or to a second access node using a second frequency band. The second access node is also broadcasting system information messages that include cell loading information.
