  • Publication number: 20220150786
    Abstract: Hybrid use of dual policies is provided to improve a communication system. In a multiple access scenario, when an inactive user equipment (UE) transitions to an active state, it may be become a burden to a radio cell on which it was previously camping. In some embodiments, hybrid load balancing is provided using a hierarchical machine learning paradigm based on reinforcement learning in which an LSTM generates a goal for one policy influencing cell reselection so that another policy influencing handover over active UEs can be assisted. The communication system as influenced by the policies is modeled as a Markov decision process (MDP). The policies controlling the active UEs and inactive UEs are coupled, and measureable system characteristics are improved. In some embodiments, policy actions depend at least in part on energy saving.

  • Publication number: 20190252689
    Abstract: A one-step in-situ electrochemical pre-charging strategy to generate thin protective films simultaneously on the surfaces of both carbon-based air-electrode and metal anode under an inert atmosphere is disclosed. The thin-films are formed from the decomposition of electrolyte during the in-situ electrochemical pre-charging process in an inert environment and can protect both a carbon air-electrode and a metal anode prior to conventional metal-oxygen discharge/charge cycling where reactive reduced oxygen species are formed. Lithium-oxygen cells after such pre-treatment demonstrate significantly extended cycle life which is far more than those without pre-treatment.
