July 12, 2016 — In advance of the first 3GPP work on the 5G standard, Verizon announced this week that it has completed its 5G radio specification in collaboration with the Verizon 5G Technology Forum, which includes Cisco, Ericsson, Nokia, Qualcomm and Samsung.
“The completion of the 5G radio specification is a key milestone toward the development of a complete 5G specification,” said Adam Koeppe, Verizon vice president network technology planning, who is leading the 5G trial efforts.
While there is much work to be done in the 5G standards process, Verizon’s effort will assist the international standards body 3GPP. Release-15 of the 3GPP’s 5G specifications will begin in September 2016 and end mid-2018. In March 2017, the RAN Working Group’s work will begin on specification for the 5G radio.
“The level of collaboration that we are seeing exceeds what we saw during 4G. This agile way of developing the specification and working with the ecosystem will enable us to get to market rapidly,” Koeppe added.
The specification provides guidelines to test and validate crucial 5G technical components, which allow chipset vendors, network vendors and carriers to develop interoperable solutions and contribute to pre-standard testing.
Carrier Looks to Accelerate 5G Innovation in Pre-commercial trials
Verizon has entered pre-commercial 5G testing in New Jersey, Massachusetts and Texas. Its goal is to accelerate the pace of innovation in wireless as well as in how the industry can deliver benefits of fiber functionality wirelessly to customers, according to a prepared release.
During the testing process, numerous 5G technology enablers have been validated, including bandwidth of several hundred megahertz in size, multiple antenna array processing and carrier aggregation.
Propagation and penetration testing across residential single and multi-dwelling units built in field locations has validated the feasibility of millimeter wave systems. Tests include throughput analysis with customer premises equipment at various locations inside the home to facilitate the study of line-of-sight and non-line-of-sight performance, and propagation modeling using barriers such as structures and foliage, all based on real-world fixed wireless applications.
3GPP Cements 5G Timeline
3GPP Technical Specifications Group RAN further agreed that the target NR scope for Release 15 includes support of the following:
During the discussion at TSG#72 the importance of forward compatibility – in both radio and protocol design – was stressed, as this will be key for phasing-in the necessary features, enabling all identified usecases, in subsequent releases of the 5G specification, according to the organization.
