Essential parts of the 5G standard have been completed with the approval of 5G New Radio (NR) specifications for non-standalone and standalone deployments of 5G. Ericsson is a key contributor to the standardization process. We are committed to rapidly applying these standards to our technology development and accelerate the commercial deployment of standard-based 5G networks.

5G NR standalone multi-vendor interoperability demonstrated

Ericsson and Intel together with China Mobile have successfully demonstrated the first 3GPP-compliant, multi-vendor Standalone (SA) 5G New Radio (NR) call. The interoperability demonstration followed the completion of the 5G NR Standalone specifications by 3GPP. The live demonstration with different players in the ecosystem marks another milestone on the path to 5G commercialization.

Following the 3GPP approval of the global 5G NR SA standard, Ericsson, Intel and China Mobile conducted a live Interoperability Development Testing (IoDT) of the newly approved technology. The live IoDT operating at 100MHz on 3.5GHz mid-band used Ericsson’s 5G NR base stations and Intel’s 5G NR UE (Intel® 5G Mobile Trial Platform) prototypes. The test achieved a downlink speed of over 1.3 Gbps.

The test complies with all key characteristics of the 3GPP 5G NR SA standard:

Multiple numerology support: Flexible OFDM (Orthogonal Frequency Division Multiplexing) waveform numerologies supporting low-band, as well as mid-band and high-band spectrum allocations for wideband operation and low latency services.

Flexible frame structure: Dynamic frame structure enables future-proof and ultra-lean design as well as self-contained data transmissions that support diverse use cases with requirements on, among others, low latency, high peak-rate, and high reliability with energy efficient transmission.

Channel codes: Channel coding schemes based on the latest technology in advanced low-density parity-check (LDPC); and Polar codes that support both extreme peak rates and high-reliability use cases.

Native MIMO support: Control and data channel support for Massive MIMO Multiple-input, Multiple-output) features based on beam-centric design; improves spectral efficiency and achieves higher data rates while boosting performance for consumers.

Ultra-lean design: Minimize any transmission not directly related to delivery of user data. Remove the need for always-on signals; more energy efficient design and reduces interference.

Expanded spectrum support: Low-bands, mid-bands, high-bands; more spectrum bands and wider bandwidth available.

The demonstration successfully carried out by the ecosystem partners is expected to accelerate the commercial deployment of standard-based 5G networks.

Global mobile industry leaders achieve multi-band 5G NR NSA

The interoperability demonstrations mark an important technology milestone toward standard-compliant trials. It is also a proof point of the ongoing industry collaboration to accelerate 5G NR for commercial network launches starting 2019.

The live over the air multiband demonstrations showcased both sub-6 GHz and mmWave end-to-end 5G NR systems, using Ericsson’s 5G NR pre-commercial base stations and Qualcomm Technologies’ 5G NR UE prototypes. The demos were conducted for the lower layer data connections. These just standardized layers are fundamental building blocks of 5G NR.

The success of this interoperability test paves the way for commercial launches of 5G standard-compliant infrastructure and devices. Going forward our 5G NR pre-commercial base stations and Qualcomm UE prototypes will enable operators to conduct live tests in their own networks.

The newly approved 3GPP standard for NSA 5G NR will use the existing LTE radio and evolved packet core network as an anchor for mobility management and coverage while adding a new 5G NR radio access carrier to enable certain 5G use cases starting in 2019.

5G standardization

The 5G standardization process is highly innovative and complex. Ericsson’s pioneering research and early collaborations with academia and other industries provide essential input for developing a standard that meets the needs of industries and society.

5G radio access keeping pace with the demands for connectivity

Radio access technologies are a fundamental component of 5G. They must support massive numbers of connected devices and meet the real-time, high-reliability communication needs of mission-critical applications in addition to increasing network speed and capacity.
