  • Publication number: 20240088963
    Abstract: Embodiments of this application provide a method and an apparatus for determining radio channel multipath information and a related device. A server obtains reference signal received powers of a plurality of downlink beams, and determines a path angle and path strength of a propagation path from an antenna in a power angular spectrum cell indicated by each power angular spectrum cell identity to a grid indicated by each grid identity, based on an association relationship between the reference signal received powers of the plurality of downlink beams and the following: a grid identity, a serving cell identity, and a power angular spectrum cell. The server can determine the radio channel multipath information based on the reference signal received powers of the plurality of downlink beams, instead of depending on map and engineering parameter information.

  • Patent number: 11930414
    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.
