Patent number: 11985615Abstract: A distributed radio frequency communication system facilitates communication between wireless terminals and a core network. The system includes a group of remote radio units (RRUs). Each RRU of the group of RRUs is coupled to an antenna to communicate with at least some of the mobile terminals and includes electronic circuitry to perform at least a first portion of a first-level protocol of a radio access network (RAN) and communicate over a fronthaul link. The system also includes a baseband unit (BBU) coupled to the core network and the fronthaul link, and communicably coupled to the group of RRUs over the fronthaul link. The RRU receives a synchronization-assisting radio-frequency signal and sends information derived from that signal to the BBU. The BBU processes the information to determine synchronization instructions which are then used to adjust a local clock in the RRU.Type: GrantFiled: December 12, 2018Date of Patent: May 14, 2024Assignee: CommScope Technologies LLCInventors: Dario Fertonani, Alan Barbieri
