  • Patent number: 10057863
    Abstract: An apparatus, computer program, and method are provided for setting a power of a cell node based on cell node gradient information. Cell node gradient information is generated based on a multiple-codeword channel quality indicator (CQI), utilizing a multiple-input-multiple-output (MIMO)-capable cell node in a network configured for communicating with a plurality of MIMO-capable user equipment. Additionally, other cell node gradient information is received that is generated for a plurality of other MIMO-capable cell nodes. The generated cell node gradient information and the other cell node gradient information are processed. Further, a power of the MIMO-capable cell node is set, based on the processing.

  • Publication number: 20180077717
    Abstract: A cellular scheduler apparatus, computer program, and method are provided for selecting user equipment based on beam or delay state information. State information is stored utilizing at least one data structure of a base station. Such at least one data structure includes, at the least, a beam data structure for storing beam state information, and/or a delay data structure for storing delay state information. At least one of the beam state information or the delay state information is received at the base station scheduler. Further, the base station scheduler is utilized to generate a communication schedule for communications between the base station and a plurality of user equipment, based on at least one of the beam state information or the delay state information. Still yet, at least one of the user equipment is selected, based on the communication schedule.

  • Patent number: 9787445
    Abstract: A system and method for inter-cell interference coordination is provided. A method for controller operation includes receiving interferer information from a device served by the controller, scheduling a cell edge device based on the received interferer information, and reporting usage information of the subset of resources to neighboring controllers. The cell edge device operates in a periphery of a coverage area of the controller, and the cell edge device is scheduled to a subset of resources. The method also includes from each neighboring controller, receiving neighboring usage information of a neighboring subset of resources reserved for cell edge devices served by the neighboring controller. The method further includes scheduling a cell center device based on the received usage information from the neighboring controllers, and transmitting to scheduled devices over their respective scheduled resources. Cell center device is scheduled to resources not in the subset of resources.
