Abstract: Systems and methods are described for determining a modulation and coding scheme for a small cell. A small cell may receive a first signal level for a first signal received at a wireless device and a second signal level for a second signal received at the wireless device, wherein the received first signal is from the small cell and the received second signal is from a macro cell. The small cell may also receive a channel quality indicator from the wireless device that indicates a channel quality for communications between the wireless device and the small cell. A signal level metric may be calculated based on the first signal level, the second signal level, and the received channel quality indicator. A modulation and coding scheme for a transmission from the small call may be determined, wherein the transmission is associated with an almost blank subframe transmission from the macro cell.

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: A method for donor selection in a relay access node includes identifying a plurality of candidate donor access nodes and obtaining one or more characteristics associated with each of the plurality of candidate donor access nodes. The method further includes determining a primary donor access node based on a comparison of the one or more characteristics between each of the plurality of candidate donor access nodes, and receiving a reference signal transmitted by the primary donor access node at a transmission power higher than a transmission power of downlink information transmitted by the primary donor access node. One or more quality characteristics of the primary donor access node are evaluated, and based on the one or more quality characteristics meeting a predetermined threshold, a connection to the primary donor access node is requested. Devices and systems relate to donor selection.

Abstract: Embodiments disclosed herein provide individual idle-mode cell reselection priority lists to wireless devices dynamically, based on real-time load conditions for frequency bands deployed within a wireless network. Load equalization operations include classifying frequency bands into congested, target, or non-congested bands, grouping similar bands, comparing loads across the various bands in to a threshold, and adjusting the priority of each frequency band accordingly. The adjusted priorities are transmitted to each wireless device as the wireless device enters idle mode.

Abstract: Systems and methods are described for sub-band selection for a wireless device during connection. An access node may receive a RACH preamble message from a wireless device. It may be determined that a received signal level associated with the message does not meet a signal level criteria. The wireless device may be instructed to transmit signal information to the access node. A sub-band that comprises a signal level that meets the signal level criteria may be selected. The wireless device may then be instructed to communicate with the access node using the selected sub-band when requesting a connection.

Abstract: Systems and methods are described for controlling a reference signal mode to facilitate beamforming. A load amount for reference signals from one or more wireless devices in communication with an access node is determined and compared with load level criteria. When the load amount meets or exceeds the load level criteria, the one or more wireless devices are directed to transmit reference signals using a subband mode of transmission. A subband quality is determined for a plurality of subbands available for the one or more wireless devices and a subband for reference signal transmission is selected from the plurality of subbands based on channel quality criteria. Wireless transmission, such as from an access node, to the one or more wireless devices is scheduled utilizing beamforming based on the reference signal.

Abstract: A first access node co-located with a second access node. The first access node communicates using a first type of wireless service. Scan results indicate whether a wireless device meets a first threshold criteria for being served by the second access node using a second type of wireless service. A time series of a count of these wireless devices is determined. From the time series, an indicator of a moving average of the time series is determined. Based on the moving average, the wireless devices are configured with an indicator of a second threshold criteria that determines whether a respective one of the wireless devices meets a second threshold criteria for being served by the first access node using the first type of wireless service.

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.
