Methods and apparatus which allow a wireless terminal (302) to simultaneously maintain connections with multiple base stations (304, 306) are described. Each wireless terminal (302) is capable of supporting multiple separate timing and/or other control loops one, for each base station connection thereby allowing the connections to operate independently and in parallel. Different control signals and/or data are transmitted on each connection that is established with a base station (302, 306). In this manner base stations (302, 306) receive different data allowing for asynchronous data transmission. The data received by the base stations (302, 306) can be supplied to a wired asynchronous network (308) without the need to combine the received data prior to supplying it to the wired network (308). The communications techniques of the invention can be used to implement soft handoffs without the need to duplicate data transmissions to multiple base stations.

L'invention concerne des procédés et un appareil qui permettent à un terminal radio (302) d'entretenir simultanément des connexions avec plusieurs stations de base (304, 306). Chaque terminal radio (302) est capable de supporter différentes boucles de synchronisation et/ou autres boucles de commande distinctes pour chaque connexion avec une station de base, les connexions pouvant ainsi fonctionner indépendamment et en parallèle. Différents signaux de commande et/ou données sont transmis par chaque communication établie avec une station de base (302, 306). Ainsi, les stations de base (302, 306) reçoivent différentes données permettant la transmission asynchrone de données. Les données reçues par les stations de base (302, 306) peuvent être fournies à un réseau filaire asynchrone (308) sans qu'il faille les combiner avant de les céder au réseau filaire (308). On peut utiliser les techniques de communication de l'invention pour appliquer des transferts souples sans devoir dupliquer les transmissions de données à plusieurs stations de base.
