Abstract: Beamforming in massive MIMO networks includes monitoring beamforming feedback from one or more wireless devices attached to an access node, when the beamforming feedback degrades, increasing a subcarrier spacing of the access node, and when the beamforming feedback stops degrading, maintaining or reducing the subcarrier spacing of the access node.

Abstract: Mitigating interference caused by external networks includes identifying air interface resources within a wireless air interface that are subject to interference from the external network, scheduling resources for a first one or more wireless devices reporting channel conditions that meet a threshold or being a threshold distance from a serving access node to avoid using the identified air interface resources, and instructing a second one or more wireless devices reporting channel conditions that do not meet the threshold or within a threshold distance from the serving access node to use the identified air interface resources.

Abstract: Systems, methods, and processing nodes are configured to perform scheduling in a wireless network utilizing a multi-user multiple-input multiple-output (MU-MIMO) operating mode, by determining that a throughput indicator of a sector meets a threshold, and adjusting a time window during which a first one or more wireless devices are removed from a MU-MIMO group and a second one or more wireless devices are added to the MU-MIMO group. The first one or more wireless devices comprise any wireless device that has a throughput below a threshold, and the second one or more wireless devices comprise any wireless device that has not been in the MU-MIMO group for a predefined time period.

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.

Abstract: Systems and methods are described for assigning a mobility parameter to a wireless device. One or more measurement reports may be collected at an access node from the wireless device. A pathloss change for the wireless device may be calculated based on the collected measurement reports. When the calculated pathloss change exceeds a threshold, the wireless device may be instructed to report surplus transmit power at the access node. The reported surplus transmit power may be correlated to preset location environments and a position of the wireless device classified based on the correlation. A mobility parameter may be assigned for the wireless device.

Abstract: Mitigating interference between access nodes in a wireless network includes determining interference caused to uplink signals received at a first access node by downlink signals transmitted from a second access node, and adjusting a guard period of a special subframe utilized by one or both of access nodes based on determining the interference, by switching special subframe formats to include a longer guard period. Overall interference is mitigated based on mutually-experienced propagation delay, and channel reciprocity. Adjustments are associated with known distances between access nodes.

Abstract: Systems, methods, and processing nodes are related to improving service in a wireless network. The method includes determining a frame configuration and bandwidth for a plurality of communication bands available for communication with a wireless device. The method includes generating a reselection priority based on one or more of the frame configuration and bandwidth for each of the plurality of communication bands. The reselection priority of each of the plurality of communication bands is based on a suitability of one or more of the frame configuration and bandwidth to service uplink traffic. The method includes transmitting the reselection priority to the wireless device. The wireless device utilizes the reselection priority in communication band reselection based on uplink traffic generated by the wireless device.

Abstract: A method and system for defining additional spread spectrum channels within a coverage area already served by an existing wireless network. A first spread spectrum channel may be defined by a first range of frequencies. A second spread spectrum channel may be defined by a second range of frequencies. A portion of the first range of frequencies may overlap with a portion of the second range of frequencies. The overlap may be such that the first spread spectrum channel and the second spread spectrum channel may carry signals that minimally interfere with each other.
