Data traffic in mobile networks continues to outpace the spectrum resources available for mobile wireless systems. Here in the Ericsson Research blog, we have previously described how licensed assisted access (LAA) enables mobile device users to be served by a combination of licensed and unlicensed spectrum bands at the same time. Watch live and On Demand shows, and manage your DVR, whether you're home or on the go. Licensed-assisted access (LAA), which conveys data information via both licensed and unlicensed bands through spectrum aggregation, becomes a promising solution to enhance the capacity of wireless systems.

Laa spectrum

To deal with the issue of co-existence with WiFi systems, LAA is required to perform listen-before-talk, which can significantly impact its resource utilization. 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.

Licensed-assisted access (LAA), which conveys data information via both licensed and unlicensed bands through spectrum aggregation, becomes a promising solution to enhance the capacity of wireless systems. In view of the potential impact on the incumbent system operating in unlicensed bands, the medium access control (MAC) protocol design for LAA system to harmonically coexist with its LAA R14 targets enhancements to support aggregation for both uplink and downlink MuLTEfire Broadening LTE technology and ecosystem to new deployment opportunities Licensed Spectrum Exclusive use Unlicensed Spectrum Shared use LAA (Licensed-Assisted Access) Targeting mobile operator deployments in Europe, Japan, and beyond2 based on 3GPP Rel. 13 and beyond LTE Carrier Aggregation with licensed 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.

Dual Connectivity, which supports both upstream and downstream user plane traffic over the unlicensed spectrum. This is built on extended LAA (eLAA), introduced in 3GPP release 14. Again, this is designed for traffic offload and not coverage so control plane traffic is transported only over the 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. It boosts capacity and speed of standard LTE data streams by augmenting using one or more data channels in unlicensed spectrum at 5GHz.
