Physical Layer API Specifications

 

These new papers, which expand last year's 5G Physical Layer API specification, allow for the assembly of small cells using components from different vendors to cope fairly easily with a mix of 5G use cases.

The latest update also contains two latest specifications, SCF223: Specification for the 5G NR FAPI P19 FrontEnd Interface and SCF224: Small Cells Network Control Mode API. Dr. Prabhakar Chitrapu, chair/leader of SCF MTS – AT&T Converged Access and Application Technology, said the outcome was a 'proud achievement.' 

"The 5G-FAPI specification package strengthens and adds to the current set of 3G and 4G specifications, which have played a significant role in enabling a wide muti-vendor ecosystem to expand the market for small cells," he said. "The creation of this suite is a proud accomplishment for the Small Cell Forum, showcasing the committed cooperation efforts of numerous member companies. These APIs also reflect our ongoing partnership with other Industry Forums and this new release integrates OpenAirInterface Software Alliance recommendations."

The SCF released the PHY API for 5G in July to encourage a competitive ecosystem for vendors of 5G small-cell hardware, software, and equipment.

The PHY API was developed with the aid of a joint effort between companies across the small cell ecosystem including, among others, Intel and Qualcomm Technologies. An open and interoperable interface between the physical layer and the MAC layer was provided for ecosystem players.
