Publication number: 20250112829Abstract: One embodiment is used in a scalable cloud environment configured to implement a plurality of virtualized entities that implement a part of a base station to provide wireless service to user equipment. The plurality of virtualized entities comprises first and second virtualized entities. Processing performed by the first virtualized entity generates data that is used by processing performed by the second virtualized entity. Cloud native software included in the scalable cloud environment is configured to collect cloud-native metrics associated with implementing the second virtualized entity in the scalable cloud environment. The existence of a congestion condition for the second virtualized entity can be determined based on the cloud-native metrics collected for the second virtualized entity and, in response to determining that the congestion condition exists for the second virtualized entity, a control action can be taken in order to throttle the first virtualized entity.Type: ApplicationFiled: January 19, 2023Publication date: April 3, 2025Applicant: CommScope Technologies LLCInventors: James J Ni, Shanthakumar Ramakrishnan, Ehsan Daeipour, Arthur J.

Patent number: 11284384Abstract: One embodiment is directed wirelessly communicating with user equipment (UE) operating using discontinuous reception (DRX). When a rank for the UE has changed is determined and, in response when that happens, if an ON duration for a current DRX cycle for the UE will elapse during a current subframe is determined. In response to making such determination about the ON duration, a dummy assignment of resource blocks on a downlink shared channel is sent to the UE. The UE extends the ON duration of the current DRX cycle in response to the dummy assignment. If a channel quality indication (CQI) report has been made by the UE is determined and, in response thereto, a modulation and coding scheme (MCS) used for communicating with the UE is updated based on the reported rank and reported CQI. The dummy assignment is not made for communicating actual data to the UE.Type: GrantFiled: May 20, 2020Date of Patent: March 22, 2022Assignee: CommScope Technologies LLCInventors: Stuart D.
