  • Publication number: 20160219457
    Abstract: A first user equipment is configured to mitigate multi-antenna inter-stream interference. A method by the first UE includes determining, based on one or more criteria, a number of multi-antenna streams whose interference can be currently mitigated by the first UE, and transmitting information based on the number of multi-antenna streams to a first network node, to a second network node, and/or to a second UE. A related method by a first network node serving or managing the first UE includes obtaining information based on a number of multi-antenna streams whose interference can be currently mitigated by a first UE at the first UE, and performing one or more radio operational tasks using the information based on the number of multi-antenna streams whose interference can be currently mitigated.

  • Publication number: 20140257928
    Abstract: Methods and systems for allocating regional inventory to reduce out-of-stock costs are described. A method may include identifying a total number of units of an item to be stored in a plurality of regions and determining an order forecast for the item in each of the plurality of regions. The method may also include receiving a unit out-of-stock cost of the item in each of the plurality of regions and calculating an expected cost for each of the plurality of regions based, at least in part, on the total number of units of the item, each region's respective order forecast, and each region's respective unit out-of-stock cost. The method may further include allocating a portion of the total number of units of the item to each of the plurality of regions to reduce a sum of the expected costs.
