Outer Loop Power Control (OLPC) system. instead of the traditional BLER-based OLPC, our OLPC solution is based on a different quality criterion: the Outage Probability. This is the so called “Outage-Based” solution which solves the problems related to the low convergence speed of the BLER-based solution under certain propagation conditions. This slow convergence is specially important for low BLER-target services as the videophone (a key 3G application) with the consequence of a considerable capacity loss.

HSDPA Channel Quality Indicator (CQI) estimator. The same concept as for the OLPC is used for the CQI estimator for HSDPA. This WCMDA evolution needs a channel quality estimator in order to adapt accordingly the transmission speed, and the ToT method is precisely, in essence, an estimator of the channel condition. The development of this product was financed by a PROFIT program of the Spanish Industry, Tourism and Trade Ministry.
