With a simple software upgrade, operators can deploy a coordinated scheduling feature in their FDD-LTE and TD-LTE networks to reduce interference between adjacent base stations., Nokia Solutions and Networks said today (4 February 2014).
This evolution of the Nokia Solutions and Networks Smart Scheduler provides up to 30 percent faster downlink speeds at the cell edge, an advantage during periods of peak congestion. Importantly, coordinated scheduling is implemented as software within the base stations, avoiding the need for any additional hardware.
In LTE networks, the algorithms used for scheduling are not standardised. With NSN’s field proven Smart Scheduler, individual base station radio resources can be highly optimised, resulting in more than 100% increase in cell edge data rates and more than 20% improvement in cell capacity today when compared with other baseline industry LTE schedulers.
NSN is now introducing a software upgrade that adds coordinated scheduling to the Smart Scheduler. With this function, neighbouring base stations will allocate their radio resources in collaboration to reduce inter-cell interference. This leads to higher downlink speeds for subscribers, especially at the cell edge where the reduction in interference between cells produces a 30% improvement.
“Mobile broadband users will experience superior performance everywhere, not just when they’re at the centre of a cell,” said Zhang Qi, vice president for TD-LTE at NSN. “Furthermore, NSN’s solution eliminates the need for any additional hardware. Our coordinated scheduling is a simple software upgrade in the base station because we want to keep the LTE network architecture lean and reduce unnecessary complexity.”
Offering the same benefits for both FDD-LTE and TD-LTE networks, coordinated scheduling is implemented in the existing NSN Flexi Multiradio 10 base stations, which run the NSN Smart Scheduler. Flexi Multiradio Base Stations are currently used in hundreds of commercial radio networks around the world, NSN said.
