Ericssson: LTE Release 13 Brings Improvements

LTE release 13, currently under standardization in 3GPP,  will significantly increase user data
rates and overall capacity, as well as support new use cases and further strengthen LTE as a vital
part of future radio access, according to a new white paper published by Ericsson.

Some of the big improvements in LTE release 13 will include:

  • Licensed assisted access (LAA) -- which used unlicense spectrum to boost overall LTE network capacity. LAA targets operator-deployed small cells in the 5GHz band.  Initially, it will support downlink traffic although a later extension is planned for uplink traffic.
  • Carrier-aggregation enhancements -up to 32 carriers in both the uplink and downlink, compared to five with LTE Release 10.
  • Multi-antenna enhancements - two-dimensional base station antenna arrays with up to 64 antenna ports are being studied for exploitation of both the azimuth and elevation domain. 
  • Latency reduction


The Ericsson white paper also touches on machine-to-machine use case for LTE.
