A mobile device comprises a receiver unit that has at least two receivers to implement multi-antenna receive diversity. A control unit estimates, at the mobile, an amount of utilization by a traffic channel of the mobile of total transmission power capacity at a base station. The mobile applies multi- antenna receive diversity in the mobile device based on the power capacity utilization. The mobile estimates an amount of power a network is transmitting to the mobile relative to a pilot reference. Other indicators are based on quality of the traffic channel between the mobile and the network, capacity limiting resources, a number of sectors in a soft hand-off in a wireless system, etc. The indicators are used to control application of multi-antenna receive diversity in a mobile device.
La présente invention concerne un terminal mobile comprenant un récepteur à au moins deux modules pour une réception en diversité d'antennes. Le contrôleur du terminal évalue la part de puissance d'émission de la station de base incombant au canal trafic. Le terminal évalue, par rapport à une référence pilote, la puissance prise par le réseau pour émettre vers le terminal. On utilise d'autres indicateurs caractéristiques, notamment, de la qualité du canal trafic entre le terminal et le réseau, des ressources limitant les capacités, et du nombre de secteurs pour les transferts sans solution de continuité dans le système radio. Ces indicateurs permettent de commander l'application de réception en diversité d'antennes par un terminal mobile.
