Publication number: 20240146429Abstract: A radio access network (RAN) operates by: determining an initial RU/UE association that allocates the plurality of UEs among the plurality of RUs via reference signal received power (RSRP) data received from the plurality of RUs; receiving RU conditions data corresponding to a set of RU conditions associated with the plurality of RUs; receiving RU constraint data associated with the plurality of RUs; assigning, via at least one iterative RU sleeping loop and based on the initial RU/UE association, the RU conditions data and the RU constraint data, an active mode to a first subset of the plurality of RUs and a sleep mode to a second subset of the plurality of RUs; and updating a dynamic RU/UE association based on the first subset of the plurality of RUs and the second subset of the plurality of RUs.Type: ApplicationFiled: October 11, 2023Publication date: May 2, 2024Applicant: ISRD Sp. z o.o.Inventors: Farinaz Kooshki, Ana Garcia Armada, Md Munjure Mowla, Adam Dawid Flizikowski, Slawomir Pietrzyk

Patent number: 11889494Abstract: A radio network operates by: converting, in accordance with a communication standard, received fronthaul communications from a plurality of radio units (RUs) into backhaul communications transmitted to a communications network, wherein the plurality of radio units are configured to engage in wireless communications with a plurality of user equipment (UEs) via a radio channel of a radio network; converting, in accordance with the communication standard, received backhaul communications from the communications network into fronthaul communications transmitted to the plurality of RUs; providing a shared scheduler associated with a radio channel that is partitioned into a plurality of physical radio blocks (PRBs), wherein the plurality of PRBs are accessible by the plurality of UEs via the RUs; and generating, via the shared scheduler, an UE to PRB to RU allocation that associates ones of the plurality of PRBs to selected ones of the plurality of UEs and selected ones of the plurality of RUs, without a UE to RU pType: GrantFiled: December 23, 2021Date of Patent: January 30, 2024Assignee: ISRD Sp. z o.o.Inventors: Slawomir Pietrzyk, Md Munjure Mowla, Adam Flizikowski, Farinaz Kooshki, Adam Girycki, Jakub Piotr Kocot

Patent number: 11870527Abstract: 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: GrantFiled: January 19, 2023Date of Patent: January 9, 2024Assignees: ISRD Sp. z o.o., ISN Sp. z o.o.Inventors: Adam Girycki, Md Arifur Rahman, Michal Piotr Pajak, Jakub Piotr Kocot, Adam Dawid Flizikowski, Slawomir Pietrzyk
