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.
