Publication number: 20240056159Abstract: This disclosure relates to apparatuses, systems, and methods for scheduling user equipment (UE) transmissions, and in particular for scheduling UE transmissions in a 5G New Radio system with a split architecture. The scheduler selects a beamforming algorithm for a UE group that includes a first UE and a second UE, where the beamforming algorithm is based on characteristics of the beamforming algorithm and/or the UE group. The scheduler determines an effective SINR for the UE group based on the beamforming algorithm and determines a summed proportion fair metric for the UE group based on the effective SINR for the UE group. The scheduler schedules a transmission for either the first UE or the UE group, based on a proportional fair metric for the first UE and the summed proportional fair metric for the UE group.Type: ApplicationFiled: March 29, 2022Publication date: February 15, 2024Inventors: Thushara HEWAVITHANA, Ranjit CAVATUR, Neelam CHANDWANI, Ziyi LI, Bishwarup MONDAL

Publication number: 20230138190Abstract: An apparatus and system of providing energy saving in a network are described. A target node receives, from a source node, a handover request to handover a UE due to at least one of entry of the source node into a power saving state or mobility optimization. In response, the target node transmits a relative energy efficiency value of Bits per Joule and periodic feedback related to a status of the UE for training an AI/ML energy saving model and stops the feedback in response to a stop parameter being met. The stop parameter is a first of: a predicted period of the source node to stay in the power saving state or time for a UE to connect to the target node, a percentage of UEs handed over that enter an idle or inactive state, and a percentage of UEs handed over that are further handed to another node.Type: ApplicationFiled: December 30, 2022Publication date: May 4, 2023Inventors: Yi Zhang, Maruti Gupta Hyde, Ziyi LI, Vaibhav Singh, Christian Maciocco, Jaemin Han

Publication number: 20220038349Abstract: An apparatus and system to provide a federated learning scheme between a RAN and connected UEs are described. A gNB-DU, gNB-CU, or LMF acts as a central server that selects an AI/ML model, trains the AI/ML model, and transmits the AI/ML model to UEs. The UEs act as local nodes that each send a model request to the central server, receive the AI/ML model in response to the request, trains the AI/ML model locally with data, and report updated parameters to the central server. The central server aggregates parameters from the local nodes and updates the AI/ML model.Type: ApplicationFiled: October 19, 2021Publication date: February 3, 2022Inventors: Ziyi Li, Alexander Sirotkin, Youn Hyoung Heo, Shu-ping Yeh, Yi Guo
