Patent

CA 2511324

Techniques for limiting transport format combination (TFC) set are disclosed. The method provides procedures used by the medium access control (MAC) layer in both the user equipment (UE) and the radio network controller (RNC) to schedule data transmission. In the inventive method, each time the maximum transmit power is reached or exceeded in a time slot for a given number of successive time periods, the physical layer will send a notification to the MAC layer, including the time slot number where maximum power was reached. The MAC layer then limits the TFC set to a minimum TFC set. The embodiment(s) provides a method and algorithm for avoiding the need for the MAC layer to determine the power needed by each TFC in each time slot.

L'invention concerne un procédé et une stratégie de sélection de combinaison de format de transport (TFC) et des algorithmes associés utilisés pour les communications sans fil. Ce procédé fournit des procédures utilisées par la couche MAC dans l'EU et le RNC pour ordonnancer la transmission de données. Dans ce procédé, chaque fois que la puissance de transmission maximale est atteinte dans un créneau, la couche physique transmet une notification à la couche MAC, y compris le numéro du créneau dans lequel la puissance maximale a été atteinte. L'invention fournit un procédé à faible coût et un algorithme permettant d'éviter que la couche MAC ne doive déterminer la puissance nécessaire pour chaque TFC dans chaque créneau.
