5G NR sub-6 GHz prototype system and trial platform
5G will make the best use of a wide range of spectrum bands, and utilising spectrum bands below 6 GHz 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 system are being utilised to drive 3GPP standardisation for a new, OFDM-based 5G NR air interface. The prototype system 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 the company’s existing 5G mmWave prototype system, operating at 28 GHz and capable of robust mobile broadband communications in non-line-of-sight environment, utilising advanced beamforming and beam-steering techniques.
The 5G NR prototype system consists of both a base station and user equipment (UE), serving as a testbed for verifying 5G NR capabilities. It supports wide RF bandwidths over 100 MHz, capable of delivering multi-gigabit per second data rates. It also supports a new integrated subframe design for significantly lower over-the-air latency than what is possible in today’s 4G LTE network. The prototype system continues Qualcomm Technologies’ development and testing of their innovative 5G designs, which they are actively contributing to 5G NR 3GPP standardization. The 3GPP 5G NR study item has begun as part of Release 14 and will feed into Release 15 work items.
