摘要： A method of operating an Open Radio Access Network (O-RAN) fronthaul interface between O-RAN radio unit (O-RU) and an O-RU controller for controlling the O-RU includes: sending, from the O-RU to the O-RU controller, a message informing whether the O-RU supports Citizens Broadband Radio Service (CBRS) operation; and if so, sending from the O-RU to the O-RU controller a report of capabilities of the O-RU including whether spectrum measurement is supported; if the O-RU supports spectrum measurement, providing an indication the O-RU supports either measurement without grant or measurement with gram from a Spectrum Access System (SAS); and sending from the O-RU to the O-RU controller a Federal Communications Commission certification identification (FCC ID) for the O-RU, Citizens Broadband Radio Service Device (CBSD) category for the O-RU, user registration identification (userId) for CBRS, installation parameters, grouping parameters, and/or a call sign device identifier provided by the FCC.

摘要： A method of optimizing synchronization signal block (SSB) beam configuration for 3rd Generation Partnership Project (3GPP) New Radio (NR) network includes: using at least one of an artificial intelligence (Al) and machine learning (ML) engine in one of service management and orchestration (SMO) module, non-real time radio access network intelligent controller (Non-RT RIC), and near-real time radio access network intelligent controller (Near-RT RIC), to derive at least one optimal SSB beam configuration for the 3GPP NR network; and communicating, by the at least one of the AI and ML engine, the derived at least one optimal SSB beam configuration to a network node of the 3GPP NR network. Both the training and deployment of the at least one of the AI and ML engine are executed in the Non-RT RIC, and a static mapping between SSB beam identifiers (IDs) and beamforming weights (BFWs) is predefined.

摘要： A wireless communications system includes radio components (O-RU, O-DU, O-CU), an ORAN Non-Real-Time RAN Intelligent Controller (Non-RT RIC) framework, an O-RU Controller and a CBSD Controller interfacing with a Spectrum Access System (SAS) using the Wireless Innovation Forum (WINNF) CBSD-SAS Interface. An example of CBSD Controller is a Domain Proxy (DP) defined by WINNF. The CBSD Controller is disclosed as an application belonging to the Non-RT RIC. This application could be an rApp. The Non RT RIC Framework operates as a broker to route information between the O-RU Controller and the CBSD Controller. Data types are defined to be exchanged over the R1 interface.

摘要： A system and method of operating an Open Radio Access Network (O-RAN, in which O-RAN the system includes: a baseband unit (BBU) having an O-RAN centralized unit (O-CU) and an O-RAN distributed unit (O-DU); an O-RAN radio unit (O-RU) remote from the BBU; and a fronthaul interface between the O-RU and the BBU. A functional split of O-RAN functions respectively assigned to O-RU and O-DU for the fronthaul interface between the BBU and the O-RU is different for downlink (DL) and uplink (UL) so that at least one of i) demodulation reference signal (DM-RS)-based channel estimation is performed by the O-DU in the DL and by the O-RU in the UL, ii) equalization is performed by the O-DU in the DL and by the O-RU in the UL, and iii) demodulation is performed by the O-DU in the DL and by the O-RU in the UL.

摘要： There is provided an Open Radio Access Network (O-RAN) that includes a fronthaul interface over which an O-RAN Distributed Unit (O-DU) and an O-RAN Radio Unit (O-RU) communicate with one another and exchange O-RAN standard defined user-plane (U-plane) packets and control-place (C-Plane) packets. The fronthaul interface carries control and management information via management-plane (M-Plane) message exchange, and timing synchronization is achieved in accordance with synchronization-plane (S-Plane) procedures, and the O-RAN accommodates communications via 2G and 3G based mobile networks.
