Swedish telecom giant Ericsson and Japanese mobile carrier Softbank Mobile have significantly improved cell-edge user performance.
Both companies joined hands to successfully demonstrate the benefits of a new feature, cooperative transmission control/coordinated scheduling in long term evolution (LTE) radio base stations.
This function, notes Ericsson, was developed by Softbank Mobile as ECO-LTE - Enhanced Cooperative transmission control on LTE.
This groundbreaking test was conducted using commercially available LTE terminals and the network was located in Kumagaya, Saitama Prefecture, Japan.
According to Ericsson, this test indicates the strong potential of coordinated radio resource management functionality in LTE networks.
Improving overall cell throughput
Ericsson provided strong support for this coordinated scheduling Softbank Mobile project which can avoid the severe interference that can otherwise be encountered at the cell edge between base stations that operate on the same frequency.
The company delivered an end-to-end LTE solution for the test, consisting of its latest multi-standard base station, the RBS 6000.
In addition, it delivered its commercially proven Evolved Packet Core (EPC) network, operations support systems software, and professional services.
This collaboration has been successful and thanks to the alliance, coordinating the base stations' use of radio resources has enabled improvement of cell-edge user throughput by a factor of two or three.
Co-ordination has also improved overall cell throughput simultaneously, adds Ericsson.
