  text: "Macrodiversity is a key technique to increase the capacity of mobile networks.
    It can be realized using coordinated multipoint (CoMP), simultaneously connecting
    users to multiple overlapping cells. Selecting which users to serve by how many
    and which cells is NP-hard but needs to happen continuously in real time as users
    move and channel state changes. Existing approaches often require strict assumptions
    about or perfect knowledge of the underlying radio system, its resource allocation
    scheme, or user movements, none of which is readily available in practice.\r\n\r\nInstead,
    we propose three novel self-learning and self-adapting approaches using model-free
    deep reinforcement learning (DRL): DeepCoMP, DD-CoMP, and D3-CoMP. DeepCoMP leverages
    central observations and control of all users to select cells almost optimally.
    DD-CoMP and D3-CoMP use multi-agent DRL, which allows distributed, robust, and
    highly scalable coordination. All three approaches learn from experience and self-adapt
    to varying scenarios, reaching 2x higher Quality of Experience than other approaches.
    They have very few built-in assumptions and do not need prior system knowledge,
    making them more robust to change and better applicable in practice than existing
    approaches."

  text: In this paper, we propose a novel similarity measure to be used for localizing
    mobile terminals by comparing measured signal power levels with a database of
    predictions. The proposed measure provides the possibility to incorporate inherent
    information about signal power level measurements requested by the serving base
    station but not reported by the mobile terminal. Increased positioning accuracy
    was observed both in simulations and with real field data
