HYBRID MODE FRONTHAUL

原文（中国語）

An open radio access network implementing a shared cell includes a distributed unit and radio units communicatively coupled to the distributed unit. Each radio unit includes circuitry for exchanging radio frequency signals with user equipment. Radio units include hybrid mode radio unit. first downstream radio unit, and second downstream radio unit. Hybrid mode radio unit is coupled to distributed unit. First downstream radio unit is coupled to distributed unit via hybrid mode radio unit. The second downstream radio unit is coupled to distributed unit via hybrid mode radio unit. Hybrid mode radio unit is configured to: (1) receive downlink control-plane and user-plane messages and uplink control-plane messages from distributed unit: (2) transmit downlink radio frequency signals from antenna(s), wherein downlink radio frequency signals are based on downlink control-plane and user-plane messages: and (3) copy and forward downlink control-plane. user-plane messages. and uplink control-plane messages to downstream radio units.
