Wireless Technology Evolution Towards 5G: 3GPP Release 13 to Release 15 and Beyond
3GPP’s strong history of standardizing the technologies that drive the largest mobile wireless ecosystems from GSM to LTE and now to 5G creates the backbone for this whitepaper by 5G Americas. LTE is expected to be the dominant mobile wireless technology well into the next decade with LTE-Advanced Pro in Rel-13 completed in 2016. The 5G Americas white paper provides a detailed discussion on the key feature enhancements that were included in 3GPP Rel-13, such as:
- Enhancements to support Active Antennas Systems (AAS)
- Licensed Assisted Access (LAA)
- Aggregation of LTE and WLAN (LWA and LWIP)
- Low power / wide area coverage for IoT applications through Cellular-IoT
- Enhancements to previously introduced LTE technologies
- Advanced Multiple-Input Multiple-Output (MIMO) antennas
- Self-Organizing Networks (SON)
- Carrier Aggregation (CA) and Dual Connectivity (DC)
- Proximity Services and Device-to-Device Communication for Public Safety (ProSe/D2D)
The white paper also provides a detailed discussion of the LTE enhancements being worked on as part of Rel-14 including further MIMO enhancements, CA enhancements, enhanced LAA (eLAA), enhanced LWA (eLWA), Voice over LTE (VoLTE) enhancements and enhancements to ProSe/D2D.
