Abstract

Un método y disposicion para controlar la potencia del F-DPCH (canal físico especializado fraccionario) en un sistema de telecomunicaciones moviles de 3ra generacion que aplica HSDPA, en particular para un equipo de usuario en traspaso flexible. Tales equipos de usuario pueden no experimentar la misma relacion de errores de bit (BER) en los enlaces ascendentes radioeléctricos y, por ello, no se específica como un equipo de usuario en traspaso flexible deriva la SIR objetivo para el bucle interno. El equipo de usuario deriva la relacion de errores R de los comandos TPC para ajustar la SIR objetivo como la máxima funcion ponderada de las relaciones de errores de los comandos TPC de todos los enlaces radioeléctricos en traspaso flexible. De acuerdo con la opcion de ponderaciones de la funcion ponderada, el equipo de usuario puede establecer su SIR objetivo de tal manera que todos los enlaces radioeléctricos pueden mantener la TPC BER por debajo o igual a la TPC BER objetivo establecida por la red. El equipo de usuario también puede elegir las ponderaciones de manera que la relacion de errores TPC objetivo se cumpla solo en el HS-DSCH servidor.
