Sofbank Mobile and Ericsson have conducted a field demonstration
of LTE cooperative transmission control and coordinated scheduling. As
a new feature in LTE radio base stations, it significantly improves
cell-edge user performance by a factor of three. The trial network was
located in Kumagaya, Saitama Prefecture, Japan, providing a combination
of urban, suburban and rural radio environments.
SOFTBANK MOBILE and Ericsson (NASDAQ:ERIC) have successfully
demonstrated the benefits of a new feature, cooperative transmission
control/coordinated scheduling in LTE radio base stations*, which
significantly improves cell-edge user performance.
The test, conducted using commercially available LTE terminals,
clearly demonstrated the strong potential of coordinated radio resource
management functionality in LTE networks.
Coordinated scheduling avoids the severe interference that can
otherwise be encountered at the cell edge between base stations that
operate on the same frequency. By coordinating the base stations’ use
of radio resources, it is possible to improve cell-edge user throughput
by a factor of two or three, while simultaneously improving overall
Ericsson provided an industry-leading end-to-end LTE solution for the
test, consisting of its latest multi-standard base station, the RBS
6000; its commercially proven Evolved Packet Core (EPC) network;
operations support systems software; and professional services.
* SOFTBANK MOBILE developed this function as ECO-LTE – Enhanced COoperative transmission control on LTE.
