Extending the benefits of LTE to unlicensed spectrum

1 Downlink only in unlicensed spectrum (SDL). RF specs and coexistence tests defined by LTE-U forum: coexistence and fair sharing can be obtained using techniques such as channel selection and CSAT (Carrier Sensing Adaptive Transmission). 2 These regions mandate specific access procedures, including Listen Before Talk (LBT),. LAA R14 targets enhancements to support aggregation for both uplink and downlink

Going above and beyond minimum requirementsMinimum requirements

Ensuring fair coexistence between LTE unlicensed and Wi-FiWorking together across the mobile and Wi-Fi industries

1 With dynamic channel selection and CSAT - Carrier Sensing Adaptive Transmission required in the small cell.. 2 LAA Licensed Assisted Access, Work item approved in 3GPP R13 June 15. In addition, New RF band support (e.g. 5GHz) needed at both device and small cell

Conformance testing

•  Coexistence and fairness test

•  Expected to be more rigorous than Wi-Fi testing today

•  Still allowing for differentiation

•  Example: LTE-U forum specifications

Standards & specifications

•  LTE-U for USA, Korea, India, other markets based on LTE R10/11/121

•  LAA for Europe, Japan and beyond defined in 3GPP R132

Spectrum regulations

•  Power, bandwidth and emission levels

•  Additional channel occupancy limits: specific access procedures required in Europe and Japan (LAA)

Founding members Alcatel-Lucent, Ericsson, LGE, Qualcomm Technologies, Inc., Samsung, Verizon all have stakes in LTE and Wi-FiCoexistence specs published March 2nd 2015, updated June based on feedback, e.g. adding uplink and VoIP test cases

Being standardized in 3GPP release 13 for completion 1H 2016 (ASN.1 freeze)Enhancements planned for release R14 and beyond3GPP will develop coexistence / performance requirements and tests

•  Presented LTE-U to Wi-Fi Alliance and IEEE at standards meetings•  An LTE-U workshop for key cellular and Wi-Fi vendors/operators

was held on May 28, 2015 with deep dive of technology•  Further collaboration on coexistence with industry is ongoing—

one-on-one and in industry groups
