Fast power control in wireless communication network
Patent type: Priority Patent Application
Patent number: EP1296464A1
Registration date: Sept. 24, 2001
Abstract
The invention relates to the controlling of transmission power of a wireless communication network, and in particular to the controlling of transmission power in the downlink direction of a GSM-network. An object of the present invention is, to provide a new and improved approach, in particular for enhancing the spectral efficiency, by realizing a fast controlling of transmission power substantially independent of any upcoming addition to a standard relating to wireless communication networks to ensure a transmission power control that is immediately available and compatible to already existing mobile stations. The invention proposes for the controlling of the transmission power the steps of receiving at a base station an uplink signal transmitted by a user equipment, detecting at least one kind of information parameter from said uplink signal during definable time periods, comparing the information parameters detected during a respective time period with each other and periodically adjusting the downlink transmission power between said base station and said user equipment in dependence on the comparison for providing a fast power control loop between said base station and said user equipment to reduce varying fading effects.
