Abstract: Monitoring a MIMO pairing efficiency of a sector to determine whether or not to enable/disable inter-band carrier aggregation. If the pairing efficiency (whether predicted or actual) is high, inter-band carrier aggregation is disabled, and if the pairing efficiency is low, then inter-band carrier aggregation is enabled. The inter-band carrier aggregation utilizes a low-frequency carrier as a primary component carrier and a high-frequency carrier as a secondary component carrier. The MIMO mode of operation utilizes the high-frequency carrier for control transmissions.

Abstract: Performing inter-band carrier aggregation based on device capability includes monitoring a dominant type of wireless devices in a wireless sector based on whether or not they are capable of inter-band carrier aggregation, and enabling or disabling inter-band carrier aggregation in the sector based on the dominant type. Enabling/disabling inter-band carrier aggregation can include allowing or preventing usage of usage of a low-frequency carrier as a primary component carrier aggregated with a high-frequency carrier as a secondary component carrier. Carriers using FDD and TDD duplexing modes are included.

Abstract: Performing handovers based on RACH capabilities includes instructing neighboring access nodes to share RACH capabilities with each other, identifying a RACH capability of wireless devices attached to a serving access node, and selecting a target access node based on matching the RACH capabilities. The RACH capabilities are associated with a format and/or a range or distance of RACH transmissions.

Abstract: At certain beamforming angles (i.e., those greater than a threshold amount) a sidelobe of a beamforming pattern used by a first sector may be pointed at wireless devices being serviced by a second sector. This causes the interference experienced by the first sector to be increased due to the transmissions of the wireless devices being serviced by the second sector. To help mitigate the interference experienced by the first sector, when the access node determines it is using a beamforming angle that may be susceptible to interference from the second sector (e.g., beamforming angle greater than a threshold), the first sector selects an amount of TTI bundling to be used by a wireless device. By configuring a wireless device to use TTI bundling (i.e., increase redundancy), the link budget for the wireless device is improved thereby lessening the effects of the interference being received via the sidelobe.

Abstract: A method of managing handovers between a plurality of relay access nodes, the method includes monitoring a latency of a donor access node communicating with the plurality of relay access nodes; determining that a quality of service corresponding to a wireless device communicating with a relay access node of the plurality of relay access nodes meets a quality of service criteria; and in response to the latency meeting a threshold, instructing the relay access node to handover the wireless device to a target access node, or instructing the donor access node to handover the relay access node to the target access node, where the target access node is the donor access node, a neighboring access node, or a second relay access node served by the neighboring access node.
