A diversity selection process for a wireless terminal having two antennas is disclosed which tests reception on both the main antenna and a diversity antenna during the period when the terminal is transmitting and tests reception of a different channel (for example, for mobile assisted hand-off) during an idle period when the terminal is neither receiving or transmitting data. The antenna with the greater signal strength is selected for the next frame. Thus, both diversity and mobile assisted hand-off measurements can be made with a single receiver.
Processus de sélection en diversité pour terminal sans fil à deux antennes, permettant de tester la réception sur l'antenne principale et une antenne de réception en diversité pendant que le terminal émet et de tester la réception d'un canal différent (p. ex. dans le cas d'un transfert assisté mobile) pendant une période d'inactivité du terminal, où il ne reçoit ni n'émet de données. L'antenne ayant la plus grande intensité de signal est choisie pour la prochaine trame. Ainsi, un seul récepteur peut servir pour fins de mesures de transfert assisté mobile et de fonctionnement en diversité.
