In this paper, the concept called multi-subframe LAA targets the carrier aggregation operation, whereby one or more low-power secondary cells (SCells) operate in unlicensed spectrum. LAA deployment scenarios encompass those with and without macro coverage, outdoor and indoor small cell deployments, as well as … LTE-LAA Spectrum Sharing System Yao Ma Communications Technology Laboratory, National Institute of Standards and Technology 325 Broadway, Boulder, Colorado, USA Abstract— To provide differentiated quality of service in long-term evolution (LTE) license assisted access (LAA) procedure, the 3GPP has defined several channel access priority classes 2018-01-10 2020-02-26 In spectrum sharing systems, such as long-term evolution license assisted access (LTE-LAA) [1]–[5] and the IEEE 802.11 wireless local area network (WLAN) systems [6], [7], reliable spectrum sensing of channel busy/idle states is needed to properly implement carrier sense multiple access with collision avoidance (CSMA/CA) schemes. In CSMA/CA, the Terrible news from Verizon, T-Mobile seeing great performance from unlicensed spectrum use. 18 dBm for unlicensed spectrum 18 dBm Distance dependent path loss, shadowing and fading ITU InH 802.11ax indoor model Antenna pattern 2D Omni-directional 2D Omni-directional Antenna height 6 m 6 m (LAA, not modelled for Wi-Fi) UE antenna height 1.5 m 1.5 m (LAA, not modelled for Wi-Fi) Antenna gain 5 dBi 5 dBi UE antenna gain 0 dBi 0 dBi LAA R13 uses the licensed spectrum for the uplink, with planned support for uplink in unlicensed spectrum in 3GPP R14. Since MulteFire only relies on unlicensed or shared spectrum, MulteFire will support R13 components for the downlink and align with the definition of R14 LAA components for the uplink in unlicensed or shared spectrum.

- MulteFire: Uses LAA and eLAA to run an LTE network entirely in the unlicensed spectrum. 3GPP standards for LWIP, LWA and LAA are formally issued as part of Release 13 (June 2016). eLAA will be included in Release 14 (2017). The MulteFire Alliance expects to publish their own standard (building on the 3GPP work) Q4 2016. LAA (Licensed Assisted Access) was introduced in 3GPP release 13 as part of LTE Advanced Pro and is a method used to designate public spectrum in the speedy and currently spacious 5GHz band and has been designed to assist standard call services.

2015-09-08 spectrum around the world, and in particular, the Listen-Before-Talk (LBT) schemes. Furthermore, fair coexistence with other technologies which use unlicensed spectrum, particularly WiFi, was an important part of the study. A Work Item is now ongoing to include LAA-LTE in the Rel-13 specifications.

Carriers can add capacity, deploy more spectrum range, and improve cell edge performance through the densification of small cell outdoor technologies.

Aug, 2017 by Pankaj in News, 5CC, 5G, Ericsson, LAA, QAM, SmarTone, LTE. Ericsson and Hong Kong' SmarTone today announced successful trial of Licensed Assisted Access (LAA) technology in a live over-the-air demonstration in Hong Kong. LAA allows the use of unlicensed spectrum in the 5GHz band in combination with licensed spectrum.

LAA targets the carrier aggregation operation, whereby one or more low-power secondary cells (SCells) operate in unlicensed spectrum. LAA deployment scenarios encompass those with and without macro coverage, outdoor and indoor small cell deployments, as well as …

Extending LTE to unlicensed spectrum globally – LAA (Qualcomm) summarizes the LAA as follows (These are not described explicitely in 3GPP, but it well describes on the motivation of LAA).

LAA Enables mobile operators to offer Gigabit Class LTE by using small chunks of licensed spectrum.

There are various ways to make use of LTE with unlicensed spectrum of which LAA seems to be the most popular and imminent.
