At this week’s Mobile World Congress in Shanghai, Qualcomm Technologies announced a 5G New Radio (NR) prototype and trial platform. The prototype operates in the sub-6GHz spectrum bands and is being used to showcase the company’s 5G designs to achieve multi-gigabit per second data rates and low latency.
The arrival of 5G will see the best use made of a wide range of spectrum bands, and using spectrum bands below 6GHz is a critical part of allowing for flexible deployments with ubiquitous network coverage and a wide range of use cases. Designs implemented on the prototype are being used to drive 3GPP standardisation for a new, OFDM-based 5G NR air interface.
The prototype will closely track 3GPP progress to help achieve timely 5G NR trials with mobile operators, infrastructure vendors and other industry players, as well as future 5G NR commercial network launches. The prototype adds to Qualcomm’s existing 5G mmWave prototype system, operating at 28GHz and capable of robust mobile broadband communications in non-line-of-sight environment, using beamforming and beam-steering techniques.
The 5G NR prototype consists of both a base station and user equipment, serving as a testbed for verifying 5G NR capabilities. It supports wide RF bandwidths over 100MHz, capable of delivering multi-gigabit per second data rates. It also supports a new integrated subframe design for lower over-the-air latency than what is possible in today’s 4G LTE network.
The prototype continues Qualcomm’s development and testing of 5G designs, which are actively contributing to 5G NR 3GPP standardisation. The 3GPP 5G NR study item has begun as part of Release 14 and will feed into Release 15 work items.
“The 5G NR prototype further demonstrates our leadership in developing a unified, more capable 5G air interface, building upon our long-standing expertise in delivering OFDM chips and technology with LTE and wifi,” said Matt Grob, executive vice president and chief technology officer of Qualcomm Technologies. “We are excited to collaborate with leading network operators like China Mobile Communications Corporation on 5G technology development and testing to support the work required for 3GPP 5G standardisation.”
Huang Yuhong, the DGM of China Mobile Research Institute, added: “We are happy to be working with Qualcomm to showcase the sub-6GHz 5G prototype system at Mobile World Congress Shanghai. This is a great example of the 5G technology collaboration we set out to accomplish when we announced the 5G Joint Innovation Center earlier this year.”
