  • Patent number: 10375585
    Abstract: A neural network is trained using deep reinforcement learning (DRL) techniques for adjusting cell parameters of a wireless network by generating a plurality of experience tuples, and updating the neural network based on the generated experience tuples. The trained neural network may be used to select actions to adjust the cell parameters. Each experience tuple includes a cell identifier, a first state, a second state, an action applied to the cell that moves the cell from the first state to the second state, a local reward, and a global reward. The neural network is updated based on whether or not each action is acceptable, which is determined based on the global reward and the local reward associated with each action.

  • Patent number: 9161331
    Abstract: Systems and methods are disclosed to provide positioning enhancement to wireless systems to determine UE positioning using UE measurements. A method implemented by a UE for enabling positioning calculation includes receiving a Signal to Interference plus Noise Ratio (SINR) threshold from a network for filtering positioning measurements and performing a plurality of positioning measurements. The method also includes removing from the positioning measurements each measurement that does not meet the SINR threshold, and sending remaining positioning measurements that meet the SINR threshold to the network. Another method implemented by a network component includes receiving a plurality of positioning measurements with a plurality of corresponding SINRs from a user device and removing from the positioning measurements each measurement with a corresponding SINR that is less than or equal to a pre-determined SINR threshold.

  • Publication number: 20140082369
    Abstract: A method and a system for shape based encrypted object usage control using a querying device includes receiving location coordinates information and requesting an access to the encrypted object based on the received location coordinates information. The granting or denying access to the object is based on a determination of whether the received location coordinates information lies within at least one spatial access boundary. The at least one spatial access boundary is defined by an arbitrary physical object shape with at least two dimensional (2D) physical measurements in direct reference to designated location coordinates information. The received location coordinates information and the designated location coordinates information each includes longitude, latitude and optionally elevation values which provide the ability to identifying a specific location in a 3D space.
