Industry leaders agree to develop new CPRI Specification for 5G

Date: Friday, September 16, 2016

CPRI, the Industry Initiative for a Common Public Radio Interface continues to evolve: CPRI cooperation has agreed to work for a new specification supporting 5G Front-haul.

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 are now launching the plan for a new specification, in addition to existing specifications, to encompass the developments for 5G.

The new Specification (eCPRI) with the 5G Front-haul support is expected to be released in August 2017, and will encompass increased efficiency and bandwidth in order to meet the needs foreseen for 5G Mobile Networks.

The eCPRI specification will be based on new functional partitioning of the cellular base station functions, positioning the split point inside the Physical Layer.

The target of the eCPRI Specification is to offer several advantages to the base station design:

  • The new split point enables ten-fold reduction of the required bandwidth
  • Required bandwidth can scale flexibly according to the user plane traffic
  • Use of main stream transport technologies like Ethernet will be enabled
  • 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

While starting the work with the new specification, the CPRI Initiative also aims to develop further releases of the current specification 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.
