Softbank Mobile, Ericsson demo new LTE feature

NEW DELHI, INDIA: Japanese mobile operator SoftBank Mobile and telecom networking equipment maker Ericsson demonstrated what they term as ECO-LTE — Enhanced CO-operative transmission control on LTE. The technology uses co-operative transmission control/coordinated scheduling in LTE radio base stations to improve cell-edge user performance.

The test, conducted using commercially available LTE terminals,  demonstrated the potential of coordinated radio resource management functionality in LTE networks.

Network was located in Kumagaya, Saitama Prefecture, Japan — a combination of urban, suburban and rural radio environments

Co-ordinated scheduling avoids interference that can otherwise be encountered at the cell edge between base stations that operate on the same frequency, say the companies.

By co-ordinating 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 cell throughput, add the companies.
