Using the Zak-OTFS \u201cmother waveform,\u201d Cohere is enhancing spectral efficiency for 4G and 5G while building a digital twin of the physical world in the run-up to programmable networks for ISAC and NTN<\/h2>\n

Today Cohere Technologies is working with communications service providers (CSPs) to address a durable and fundamental problem in maximizing spectral efficiency. Given its criticality to effective, performant wireless communications, there\u2019s a straight line from\u00a0 improving spectral efficiency to service quality, operational cost and return on the precious capital spent to acquire frequency licenses.\u00a0<\/p>\n

In the process of addressing this issue with its Universal Spectrum Multiplier (USM), Cohere has also set a course toward enabling two use cases that have become synonymous with 6G: integrated sensing and communications (ISAC) and the convergence of non-terrestrial networks (NTNs) and terrestrial networks (TNs). Speaking with RCR Wireless News during the Telecom Infra Project\u2019s FYUZ event in Dublin, Ireland, Cohere\u2019s Chairman and CEO Ray Dolan discussed how the company is delivering results today while setting the stage for a massive coming wave of innovation in how mobile networks are managed and monetized.\u00a0<\/p>\n

Working with Vodafone<\/a>, Cohere used its USM software to increase performance of the CSP\u2019s multi-vendor Open RAN 5G network across a multi-cell cluster near Madrid, Spain. With Bell Canada<\/a>, Cohere\u2019s USM technology was successfully used to increase performance in single-user and multi-user MIMO systems transmitting in the 850 MHz band. Notably, the USM was integrated with existing 5G Standalone network infrastructure provided by a major network equipment vendor.\u00a0<\/p>\n

Cohere\u2019s USM is built on Delay-Doppler channel modeling and works with 4G and 5G networks in both FDD and TDD configurations. Using machine-learning techniques, USM enhances scheduling and beamforming capabilities to understand traffic flows and patterns. With this information, CSPs can dynamically adjust capacity and coverage based on real-world network and user behavior.<\/p>\n

Dolan described USM as a Layer 2 and Layer 3 solution that builds on work done in the radar industry. \u201cWe listen to reference symbols that are in the standard,\u201d he said. \u201cIt\u2019s completely transparent to the radio layer, the physical layer\u2026From that it quickly discerns what the channel state is to every attached user\u2026And then it provides that channel state to the scheduler so now when a base station schedules users it already knows what the channel state is to every attached user. When you know the channel state, you schedule with perfect knowledge. You\u2019re not guessing anymore and the performance is significantly better.\u201d\u00a0<\/p>\n

Further down in stack in Layer 1, Cohere in October announced its Pulsone Technology<\/a> to serve as the foundation for future ISAC and NTN solutions. Pulesone (a portmanteau of \u201cpulse\u201d and \u201ctone\u201d) uses the Zak-OTFS (Orthogonal Time Frequency Space) waveform which was patented in 2010 by Cohere founders Shlomo Rakib and Ronny Hadani.\u00a0<\/p>\n

Dolan referred to OTFS as the \u201cmother waveform. It is all waveforms; it is the mathematical generalization, if you will, of all of the 3GPP waveforms to date\u2026It can do TDMA in one extreme, it can do FDMA in another extreme, it can do all of the other waveforms that we\u2019ve done in history\u2026It\u2019s a pulse when it\u2019s trying to address delay; it\u2019s a tone when it\u2019s trying to address Doppler.\u201d\u00a0<\/p>\n

Pulses map to sensing and radar-based solutions while tones generally map to communications-based solutions. This directly aligns with the outlook for ISAC, a marquee potential 6G use case that would leverage distributed mobile network infrastructure to detect objects moving through the physical environment. ISAC is seen as a priority for the defense industry, and it could be used for a range of other applications such as smart cities, health monitoring and autonomous vehicles.\u00a0<\/p>\n

\u201cWe are both a radar technology and communication technology in one,\u201d Dolan said. \u201cSo that\u2019s going to give us a huge advantage\u201d as 3GPP progresses 6G standards. \u201cVery soon we\u2019ll realize that every antenna is a sensor\u2026Pretty much like Find My iPhone, you\u2019re going to have find my everything.\u201d\u00a0<\/p>\n

With regard to NTNs \u2014\u00a0and further integration of NTNs and TNs \u2014\u00a0Dolan acknowledged it\u2019s \u201cearly innings,\u201d but noted we\u2019re currently in a \u201crenaissance\u201d as private sector development of launch capabilities has materially dropped the price of delivering payloads to orbit which, in turn, has led to a boom in space-based assets. To overcome the signal delay of transmissions from space, along with the Doppler spread caused by satellites in motion, Cohere \u201cwill have a very strategic role in addressing the delay and Doppler impairments that are currently challenging NTNs\u2026We\u2019ll be bringing broadband profitably to those NTNs.\u201d\u00a0<\/p>\n

The bigger picture here, Dolan said, is an \u201celastic, programmable Layer 1 platform and an elastic, programmable Layer 2 platform\u201d capable of working on any spectrum or silicon, at the edge and in the cloud. \u201cThis is what Open RAN was all about \u2013 it was innovation,\u201d not creating a new way to exert pricing pressure on vendors. \u201cWhat the industry really needs is massive innovation and driving to cloud economics.\u201d\u00a0<\/p>\n

Final thought tying the discussion together, Dolan said: \u201cLong term, it\u2019s going to be a path to massive increases in profitability.\u201d\u00a0<\/p>\n<\/div>\n\n","protected":false},"excerpt":{"rendered":"
