CPRI, the Industry Initiative for a Common Public Radio Interface continues to evolve: CPRI cooperation have now released the first eCPRI specification (1.0). The new specification will support the 5G Front-haul and will provide enhancements to meet the increased requirements of 5G. Following the successful program to enhance the CPRI Specification to support novel Radio Access Technologies and increasing capacity demands, Ericsson, Huawei Technologies, NEC and Nokia have released the new specification on 31 August of 2017 as previously announced, in addition to existing specifications, to encompass the developments for 5G. The new Specification (eCPRI) with the 5G Front-haul support includes increased efficiency in order to meet the needs foreseen for 5G Mobile Networks. The eCPRI specification is based on new functional partitioning of the cellular base station functions, positioning the split point inside the Physical Layer (i.e. Layer 1).
The eCPRI specification offers several advantages to the base station design:
- The new interface enables ten-fold reduction of the required bandwidth
- Required bandwidth can scale flexibly according to the user plane traffic
- Use of packet based transport technologies will be enabled. Main stream technologies like Ethernet, open the possibility to carry eCPRI traffic and other traffic simultaneously, in the same switched network, e.g. one Ethernet network can simultaneously carry eCPRI traffic from several system vendors. In addition, the use of well-established protocols, such as Ethernet-OAM is possible for operation, administration, maintenance, provisioning, and troubleshooting of the network
- The new interface is a real-time traffic interface enabling use of sophisticated coordination algorithms guaranteeing best possible radio performance
- The interface is future proof allowing new feature introductions by SW updates in the radio network
In addition to the new eCPRI specification, the work continues to further develop the existing CPRI specifications to keep it as a competitive option for all deployments with dedicated fiber connections in Fronthaul including 5G.
CPRI Specifications will be openly available for the benefit of the wireless industry. Key benefits for Network Operators are the availability of a wider radio base station portfolio with adaptability to all deployment scenarios and a shorter time to market. The CPRI Specifications enable base station manufacturers and component vendors to focus their research and development efforts on their core competencies.
The CPRI Initiative complements current activities in existing standardization bodies. The interfaces developed will be used for radio base station products in mobile systems.
