Load distribution in a network of small-cell base stations

A network device may make a determination that a first backhaul connection, which serves a first base station, is congested and that a second backhaul connection, which serves a second base station, is not congested. This determination may be made based on a first periodic data cap imposed on the first backhaul connection, a traffic load on the first backhaul connection, a second periodic data cap imposed on the second backhaul connection, and a traffic load on the second backhaul connection. In response to the determination, the network device may configure a value of a cellular communication parameter utilized by one or both of the base stations. The configuration may comprise periodic adjustments of the value of the cellular communication parameter. The periodic adjustments may cause one or more mobile devices to be handed-over between the first base station and the second base station.

Systems and methods for controlling a reference signal mode to facilitate beamforming

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.

Method and network node for improving resource utilization of a radio cell

The present invention relates to a method of a network node for improving utilization of resources of a cell 102 provided by a radio base station (RBS), the cell covering a geographical area and being a cell served by a low power node (LPN) 101 of the RBS in a heterogeneous network 100. The method comprises determining a load of downlink (DL) resources of the cell used for wireless communication terminal(s) 104 connected to the cell. The method also comprises deciding, based on said determined load, that the DL bandwidth of the cell available for scheduling should be adjusted, allowing the power of the LPN to be reallocated for the adjusted bandwidth available for scheduling whereby a transition zone area 103 between the LPN and at least one neighboring node 105 will be adjusted accordingly. The transition zone is an area in which a path-loss is lower to the LPN than to the at least one neighboring node but a received DL power density is lower from the LPN than from the at least one neighboring node.

Directing a UE to forgo requesting handover to congested neighbor

Disclosed are methods and systems for requesting a UE to forgo handover to a congested neighbor. In particular, a wireless communication system may serve the UE over an air interface connection between the UE and the first base station. While serving the UE, the wireless communication system may receive from the UE a handover request requesting a handover of the UE from the first base station to a second base station. In response to receiving from the UE the handover request, the wireless communication system may determine that the second base station is threshold congested, and, responsive to the determining, (i) deny the handover request and (ii) send to the UE a command for the UE to withhold transmission of further requests for handover of the UE from the first base station to the second base station.

Intelligent radiation selection for antennas in a wireless communications environment

Devices, systems, and methods for providing improved network performance in wireless communications networks using intelligent radiation selection are provided. A radio is communicatively coupled to an antenna and configured to provide a signal to the antenna for broadcast from a cell site. One or more input components are communicatively coupled to the radio to provide information on at least one of an internal or an external condition of the antenna, so that the radio can adjust or modify the signal provided to the antenna to change an emitted pattern of radiation from the antenna to reduce signal loss, or recover or help maintain an area of coverage provided by the antenna.
