LTE Broadcast Test Specifications demonstrate Device Conformity

July 9, 2015

By Olivier Genoud, TF160 Leader

3GPP has always recognized the importance of having standardized test specifications available to manufacturers and certification bodies, in order to ensure the highest level of interoperability of mobile devices.

In the first half of 2015 a new important milestone was reached by the test experts from 3GPP Task Force 160 (TF160). In collaboration with test platform vendors (providing wireless network simulators) and device manufacturers (providing real wireless handsets), TF160 have completed the verification of Release 11 TTCN-3 protocol test cases specified for the FDD part of the eMBMS Service Continuity (eMBMS-SC) Feature.

The Evolved Multimedia Broadcast/Multicast Service for LTE (eMBMS), or “LTE Broadcast”, enables the delivery of the same content simultaneously to a very high number of users through the efficient usage of radio resources. It is particularly suited to the delivery of live video events, public alerts and the distribution of software updates for mobile devices.

3GPP RAN Workshop on LAA

Beijing, August 29, 2015

3GPP work on Licensed-Assisted Access (LAA) continues to attract wide industry attention, especially with regard to the coexistence mechanisms being designed for LTE to operate in unlicensed spectrum. Because of this 3GPP RAN has decided to hold an open industry workshop on LAA. The workshop will take place in Beijing on August 29, 2015. 

The LAA project was started to study the necessary modifications of LTE to operate in unlicensed spectrum. The project has recently reached an important milestone with the completion of the feasibility study and the approval of the corresponding Technical Report 36.889. Based on the conclusion of the study 3GPP RAN has decided to move the project to normative phase with the specification of LAA downlink operation in Rel-13 (uplink operation will be specified in a later release of LTE). The detailed objectives of the Rel-13 specification work can be found in RP-151045.


RAN at ATIS 5G Symposium

June 8, 2015

Dino Flore, the Chairman of the 3GPP RAN Group, has delivered a presentation to the ATIS 5G Symposium - providing an outline of the main features for the evolution of LTE in Release 13 and our initial plans for 5G.

3GPP Release 13 advances include the following highlights:

  • Offload to unlicensed spectrum, considering both LTE/Wi-Fi interworking and LTE over unlicensed (LAA)
  • Enhancements for Carrier Aggregation (up to 32 CCs)
  • Elevation Beamforming / Full-Dimension MIMO
  • Study of downlink multi-user transmissions using superposition coding
  • M2M (in 3GPP this is MTC) enhancements
  • New radio optimized for the low end of the IoT market
  • D2D Enhancements

Speaking at the Symposium, co-located with the "Big Telecom Event" in Chicago on June 8, Dino Flore moved from the now towards the future giving delegates an idea of the timeline for the 3GPP standardization effort for next generation cellular technology, aka 5G. 


RIO Welcomes RAN

May 6, 2015

This April saw the first ever RAN working group meeting in Brazil. RAN4 was hosted in Rio de Janeiro by Qualcomm Inc. Keysight Technologies (formerly Agilent Technologies) and TIM Brasil. The meeting was inspired by the Brazilian Communication Ministry, and supported by CPqD Foundation, a Brazilian research institute who led the work in RAN4 to specify the “Brazilian” RF band 31 (450 MHz) back in 2012.

The technical work was typically intense and varied including topics such as requirements for UE receivers with four antennas, which have been in the core standards since Release 8 but never fully specified. Quadruple carrier aggregation is now in full swing as well as the highly topical licensed assisted access (LAA) work to define the co-existence between LTE and WLAN in the 5 GHz ISM band.


An Interview with Philippe Reininger - RAN3 Chairman

April 12, 2015

In an interview with IIR – to promote their “RAN & Backhaul Networks 2015” Conference (Berlin, 20 - 21 May 2015) - Philippe Reininger, Chairman 3GPP RAN WG3, was asked some questions on 3GPP developments.

He talks about Release 12 making small cells and hyper dense deployments a reality thanks to improvements and new features for the legacy architecture. The interview also covers backhaul developments in ideal and non-ideal environments and looks at fronthaul ideas.
