  • Wireless communication network with master distributed unit and methods for use therewith
    Patent number: 11870527
    Abstract: A radio access network operates by obtaining, at a scheduler, CSI corresponding to a plurality of RUs associated with a master DU and another plurality of RUs associated with at least one other DU, wherein the CSI associated with the another plurality of RUs is obtained via another scheduler or via the at least one other DU; allocating, based on the CSI, a resource allocation for resource blocks associated with the plurality of RUs and the another plurality of RUs; negotiating with the another scheduler to obtain PRB resources of RUs controlled by the another scheduler; generating, based on the CSI, precoders associated with the plurality of RUs and the another plurality of RUs; and facilitating, via the master DU and based on the precoders and the resource allocation, contemporaneous transmission to a user equipment UE via the plurality of RUs and the another plurality of RUs and contemporaneous reception from the user equipment UE via the plurality of RUs and the another plurality of RUs.
    Type: Grant
    Filed: January 19, 2023
    Date of Patent: January 9, 2024
    Assignees: ISRD Sp. z o.o., ISN Sp. z o.o.

  • Cooperative radio resource allocation in a wireless communication network and methods for use therewith
    Patent number: 11502793
    Abstract: A cooperative radio resource manager operates by: obtaining constraint data indicating a plurality of radio network constraints and channel state information (CSI) corresponding to wireless communications between a plurality of client devices and a plurality of remote radio heads; performing a first sub-problem optimization, subject to the plurality of radio network constraints, to generate an remote radio head (RRH) to client device association that associates a corresponding one of the plurality of remote radio heads to each of the plurality of client devices and further to generate a physical resource block (PRB) allocation that allocates PRBs of each RRH among the plurality of client devices.
