Method for optimizing uplink power-control parameters in LTE
First Claim
1. A computing system for setting uplink power-control parameters for a cell within a wireless network, the system comprising:
- a power-metric determination mechanism configured to determine a long-term power metric for the cell based on an average uplink path-loss parameter calculated over a plurality of user devices over a pre-determined time interval;
a cell-type determination mechanism configured to determine a type for the cell based on the long-term power metric; and
a power-control-parameter determination mechanism configured to determine a set of power-control parameters for the cell based on the cell type.

Abstract
One embodiment of the present invention provides a system for setting uplink power-control parameters for a cell within a wireless network. During operation, the system receives parameters associated with uplink power for a plurality of user devices within the cell over a predetermined time interval, and averages the received parameters over the user devices and the predetermined time interval to obtain an averaged parameter. The system then determines a set of power-control parameters for the cell based on the averaged parameter, and sends the set of power-control parameters to the user devices to allow the user devices to control transmission power using the set of power-control parameters.
