Abstract

HARQ(ハイブリッド自動再送制御)を行う無線通信システムにおいて、移動局は、ACKの受信により、自局のHARQプロセス状態をフリー状態に戻す。この状態で、スケジューリング基地局から、再送のためのリソースを割当てるためのSA(Scheduling assignment)を受信すると、移動局は、送信すべき新データがない場合には、自局はフリー状態であることを通知する送信プロセス状態通知を送信する。これにより、基地局は、移動局がフリー状態であることを認識し、自局のHARQプロセス状態をフリー状態に戻し、この移動局へのリソース割当てを停止する。
Dans un système de transmission radio formulant une requête automatique de retransmission hybride (HARQ), lorsqu’une station mobile reçoit un accusé de réception, son système de traitement HARQ revient à l’état libre. Dans cette configuration, lorsque la station mobile reçoit une affectation de répartition (SA) pour allouer des ressources en vue d’une retransmission à partir d’une station de base assurant la répartition, la station mobile transmet un rapport d’état du processus de transmission en indiquant qu’elle est à l’état libre s’il n’y a aucune nouvelle donnée à transmettre. La station de base en déduit que la station mobile est à l’état libre ; elle reconfigure alors son statut de traitement HARQ pour le remettre à l’état libre et interrompt l’allocation de ressources à destination des stations mobiles.
In a radio communication system performing HARQ (hybrid automatic retransmission control), when a mobile station receives ACK, it returns its HARQ processing state to a free state. In this state, when the mobile station receives SA (scheduling assignment) for assigning resources for retransmission from a scheduling base station, the mobile station transmits a transmission process state report reporting that it is in the free state if no new data to be transmitted is present. Thus, the base station recognizes that the mobile station is in the free state and resets its HARQ processing state to the free state and stops resource assignment to the mobile stations.
