  • Virtualized massive MIMO in multi-operator wireless networks
    Patent number: 10749580
    Abstract: A method and device for adjusting a channel precoding matrix for one or more users operating in a virtualized Massive Multi-Input Multi-Output (M-MIMO) wireless network managed by a neutral host. Each of the users receive wireless services from one or more service providers (SP). For each service provider, a set of N antennas are selected from all available antennas managed by the neutral host. Channel information for each user of each service provider is obtained. A precoding matrix from each SP is defined according to each SP channel and state information. If all channel state information (CSI) parameters are known, and if the CSI parameters are all known, a final precoding matrix based on the known CSI is derived, whereas if only a subset of CSI parameters are known, a final precoding matrix based on the known subset CSI parameters is derived.
