Abstract: Systems and methods are described for determining an access node for a wireless device. A first signal may be transmitted from a first access node with an increased signal level. An indication of a first adjustment factor based on the increased first signal level may also be transmitted from the first access node. Signal information may then be received from a wireless device, where the signal information includes a determined first signal level associated with the first access node and a determined second signal level associated with a second access node. The determined first signal level from the signal information may comprise a received signal level of the first signal decreased by the first adjustment factor. Based on the signal information, one of the first access node and the second access node may be selected for communication with the wireless device and the wireless device may be instructed to communicate with the selected access node.

Abstract: A Long Term Evolution (LTE) access node to serve User Equipment (UEs) with a wireless Carrier Aggregation (CA) data communication service. A data processing system schedules CA Primary Component Carriers (PCCs), CA intra-band Secondary Component Carriers (SCCs) and CA inter-band SCCs for the UEs. A wireless transceiver wirelessly exchanges user data with the UEs based on the scheduling to serve the UEs with the CA PCCs, the CA intra-band SCCs, and the CA inter-band SCCs. The data processing system detects that a number of the UEs exceeds a UE threshold, and in response, identifies the UEs that use an LTE channel for their CA inter-band SCCs but not for their CA PCCs. The data processing system disables the LTE channel for the UEs that use the LTE channel for their CA inter-band SCCs but not for their CA PCCs.

Abstract: A method and system for controlling wireless communication over an air interface between a base station and a user equipment device (UE) served by the base station. In examples, the base station is configured to use a particular modulation and coding scheme (MCS) to transmit downlink control signals over the air interface to the UE without the base station beamforming the downlink control signals to the UE. Responsive to the base station determining that the UE is experiencing threshold poor RF conditions on the air interface, the base station reconfigures itself to beamform downlink control signals to the UE. And, given that the base station is reconfigured to beamform downlink control signals to the UE, the base station further reconfigures itself to use a higher-order MCS to transmit downlink control signals to the UE.

Abstract: A method and system for proactively managing a base station neighbor list. A base station or other network node tracks changes to the base station's neighbor list and identifies a recurring pattern of changes, in correspondence with a particular time of day for instance. The base station or other node then proactively changes the base station's neighbor list in anticipation of a recurrence of the identified pattern, such as in anticipation of recurrence of the time of day for instance. Advantageously, this method can help to reduce the extent to which the base station engages in an automatic neighbor relation process, and thus reduce the extent of signaling and other issues associated with engaging in that process.

Abstract: In a long term evolution (LTE) network, coordinated multipoint (CoMP) and transmission time interval (TTI) bundling can both help to improve uplink communications, but both can also place a burden on network resource. Further, since both utilize redundancy to improve uplink communications, albeit in different ways, use of CoMP and TTI bundling may be considered unnecessary. Accordingly, example methods and systems are provided that may help to balance the application of TTI bundling and CoMP.

Abstract: Link adaptation for an uplink channel is dynamically performed based on changes in uplink resources in the wireless network, the changes based on frame configuration. If the ratio of uplink to downlink subframes in the new frame configuration is smaller, the throughput is increased by increasing a modulation and coding scheme of the uplink channel, and transmit power of wireless devices. If the ratio of uplink to downlink subframes is increased in the new frame configuration, the throughput is decreased, and the wireless device is instructed to transmit using reduced transmit power.

In response to determining this increase, the methods include activating a coordinated transmission mode for one or more standard-powered wireless devices.

Abstract: Disclosed herein is a method and system for controlling base station buffering of data. In an example method, the base station serves a wireless communication device (WCD) over an air interface, where the air interface encompasses a quantity of channels on which the base station serves the WCD, where the base station is configured to buffer, in a data buffer, data awaiting transmission to the WCD, where the buffer has a fullness-threshold defining a maximum quantity of data that the base station will buffer for the WCD, and where the base station is configured to respond to the quantity of data in the buffer meeting the fullness-threshold by increasing the quantity of channels. Then, while serving the WCD, the base station determines an extent to which the WCD provides connectivity between at least one other device and the base station, and sets and applies the fullness-threshold based on the extent.

Abstract: Interference caused between neighboring access nodes deploying wireless air-interface resources in different frame configurations while using the same frequency sub-band is mitigated by modifying the subframes deployed by a first access node by muting the subframes in the first frame configuration. Wireless resources from a different frequency sub-band can be aggregated towards the interfering subframes. A third access node adjacent to the first access node may deploy wireless resources in the first frame configuration and using the second frequency sub-band. A determination of how to reconfigure the interfering subframes is based on numbers of wireless devices in potential interference zones between each access node.

In particular, the base station will respond to the occurrence of that transition by starting to beamform downlink transmission to the device on the first carrier.

Abstract: Methods and systems for controlling service by a base station when the base station is serving both a first UE without carrier aggregation and a plurality of second UEs with carrier aggregation. As a basis for invoking carrier aggregation service for the first UE, the base station selects one of the second UEs to transition from being served by the base station with carrier aggregation to being served by the base station without carrier aggregation. The base station makes such a selection based at least in part on a modulation and coding scheme that the base station uses to serve the selected one of the second UEs. The base station transitions from serving the selected second UE with carrier aggregation to serving the selected second UE without carrier aggregation. And the base station transitions from serving the first UE without carrier aggregation to serving the first UE with carrier aggregation.
