IEEE Workshop on Large-Scale Antenna Systems in Licensed and Unlicensed Bands


IEEE Workshop on Large-Scale Antenna Systems in Licensed and Unlicensed Bands 
in conjunction with IEEE Globecom 2017, Singapore

Large-Scale Antenna Systems (LSAS), widely known as massive MIMO, have recently emerged as a potential disruptive technology for fifth-generation (5G) wireless communications. On one hand, sub-6 GHz LSAS have taken the expected role of providing an umbrella of high-capacity and ubiquitous coverage. Indeed, massive MIMO systems enjoy many more spatial degrees of freedom (d.o.f.) than the number of user terminals to be served, hence making them resilient to the effects of uncorrelated noise and small-scale fading. This effectively enables them to provide large spectral-efficiency gains in fast-changing propagation environments. On the other hand, millimeter-wave (mmWave) LSAS will be deployed in conjunction with sub-6 GHz LSAS to augment the network capacity for short-range and low-mobility scenarios. This may prove extremely helpful in densely crowded environments such as shopping malls, airports, etc.

Due to the scarcity of available licensed spectrum, future LSAS are also envisioned to make extensive use of unlicensed frequency bands, now embraced as valuable assets for traffic offloading and/or throughput boost via aggregation. A tight integration of licensed and unlicensed spectrum however poses various challenges, and a fair coexistence between the new technologies and the ones already operating in the unlicensed band, e.g., IEEE 802.11x (WiFi), is still a concern. In this context, LSAS and their abundant spatial d.o.f. are foreseen to become a game changer.

Though some initial steps toward the implementation of LSAS have already been taken, there are still several key challenges that need to be tackled, before the benefits in terms of increased spectral efficiency, coexistence, and spatial reuse can be fulfilled. This new workshop will bring together academic and industrial experts to identify and discuss technical challenges and recent results related to the role of LSAS in improving spectral efficiency in both licensed and unlicensed bands. Topics of interest include, but are not limited to the following:

• Mathematical framework for the analysis of sub-6 GHz and mmWave LSAS
• System-level and deployment studies of sub-6 GHz and mmWave LSAS
• Network architecture and use cases for LSAS, e.g., access, backhaul, front-haul, etc.
• Radio propagation models and measurement campaigns for LSAS
• Experimental performance demonstrations and tests of LSAS
• Cross-layer design of licensed and unlicensed LSAS
• Modeling and analysis of LSAS/WiFi coexistence in unlicensed bands, e.g., downlink-only LSAS or more advanced duplexing, traffic switching or traffic aggregation between LSAS and WiFi, etc.
• Shared use of sub-6 GHz and mmWave bands by multiple LSAS operators
• Channel estimation techniques and protocols for WiFi-aware unlicensed LSAS
• Architectural and standardization changes required to accommodate unlicensed LSAS
• Economical and regulatory frameworks for LSAS operating in unlicensed bands

The workshop accepts only novel, previously unpublished papers. Prospective authors are encouraged to submit a standard IEEE conference style paper to this workshop through the EDAS submission system. (If any problem during submission is encountered, please contact the workshop chairs). All submissions should be written in English with a maximum paper length of six (6) printed pages (minimum 10-point font) including figures, without incurring additional page charges. One (1) additional page is allowed with a charge of USD100, if accepted. Accepted papers must be presented at the workshop. The presenter must register for the workshop before the deadline for author registration. Failure to register before the deadline will result in automatic withdrawal of the paper from the workshop proceedings and the program. All papers selected for publication will be included in the IEEE Globecom proceedings and IEEE digital library.
