  • Patent number: 11228364
    Abstract: Systems and methods relating to adjusting uplink coverage in a cellular communications network are disclosed. In some embodiments, a method of operation of a network node to adjust uplink coverage for one or more cells in a cellular communications network comprises determining that there is a need to adjust uplink beam transformations for one or more cells of a plurality of cells in a cellular communications network. For each cell of the one or more cells, the uplink beam transformation for the cell is a transformation of received uplink signals for the cell from an antenna domain to a beam domain. The method further comprises, upon determining that there is a need to adjust the uplink beam transformations for the one or more cells, determining new uplink beam transformations for the one or more cells and applying the new uplink beam transformations for the one or more cells.

  • Patent number: 11071020
    Abstract: Interference costs on virtual radio interfaces can be modeled as a function of loading in a wireless network to estimate changes in spectral efficiency and/or resource availability that would result from a provisioning decision. In one example, this modeling is achieved through cost functions that are developed from historical and/or simulated resource cost data corresponding to the wireless network. The cost data may include interference data, spectral efficiency data, and/or loading data for various links over a common period of time (e.g., a month, a year, etc.), and may be analyzed and/or consolidated to obtain correlations between interference costs and loading on the various links in the network. As an example, a cost function may specify an interference cost on one virtual link as a function of loading on one or more neighboring virtual links.

  • Patent number: 10425956
    Abstract: A hierarchical link scheduling system and method is provided. A central controller gathers network information, including global parameters and long term demands, and determines an initial schedule for link activation based on these variables. A scheduler receives the initial schedule and modifies the initial schedule based on local parameters, inter-schedule negotiation, or other short term or localized requests. The scheduler activates the links according to the modified schedule. Accordingly, the scheduler can be responsible for modifying the initial schedule provided by central controller with localized or short term requests or demands, and providing the necessary parameters to enable link activation between nodes according to the modified schedule.
