As small cells are deployed in an unplanned manner, in the same frequency channel as the macro carrier, several challenges must be addressed: 1) how to minimize downlink interference to macro users, 2) how to reduce or eliminate uplink noise that might affect neighboring small cells and macro cells, and 3) how to provide seamless mobility for users in idle and connected modes. This is especially a concern for small cells deployed with closed access.

Therefore, small cells need to self configure in such a way so that they seamlessly integrate and operate satisfactorily with the existing small cell macro network and provide excellent performance, regardless of their location within a residence or an enterprise within the macro network.

Qualcomm Research has developed UltraSON™, a comprehensive suite of self-organizing network features to address these challenges. The UltraSON suite, which is extensively analyzed and field tested, is currently commercial in Qualcomm’s FSM™ chipsets.

Project Features

UltraSON Transmit Power Calibration Suite

This suite addresses various algorithms and techniques small cells use to provide appropriate range and manage downlink femto-macro interference.

UltraSON Uplink Interference Management Suite

The uplink interference suite addresses the algorithms and techniques to manage interference caused by small cells users on the macrocell and vice versa.

UltraSON Mobility Management Suite

The mobility management suite addresses efficient small cell discovery mechanisms in idle and active mode for all mobiles including legacy devices.
