Abstract
(EN)
A base station comprises a transmission buffer for storing a service data unit received from an access gateway, a retransmission buffer for storing a packet data unit to be retransmitted through a down radio link, a scheduler for scheduling allocation of a radio resource to a user device and outputting scheduling information, and a transmission signal processing means for generating a transmission signal including the data stored in the transmission buffer or the retransmission buffer according to the scheduling information. The scheduler determines the content of the scheduling information so that data addressed to the user device requesting handover is transmitted prior to data addressed to a user device not requesting handover.

La présente invention concerne une station de base comprenant une mémoire tampon de transmission pour stocker une unité de données de service reçue à partir d'une passerelle d'accès, une mémoire tampon de retransmission pour stocker une unité de données de paquets à retransmettre à travers une liaison radio descendante, un planificateur pour planifier l'allocation d'une ressource radio à un dispositif utilisateur et pour émettre des informations de planification et un moyen de traitement de signal de transmission pour générer un signal de transmission comprenant les données stockées dans la mémoire tampon de transmission ou la mémoire tampon de retransmission selon les informations de planification. Le planificateur détermine le contenu des informations de planification de manière que les données adressées au dispositif utilisateur demandant le transfert soient transmises avant les données adressées à un dispositif utilisateur ne demandant pas de transfert.

 基地局は、アクセスゲートウエーから受信したサービスデータユニットを格納する送信バッファと、下り無線リンクで再送されるパケットデータユニットを格納する再送バッファと、ユーザ装置に対する無線リソースの割当を計画し、スケジューリング情報を出力するスケジューラと、送信バッファ又は再送バッファに格納されたデータを含む送信信号を、スケジューリング情報に従って作成する送信信号処理手段とを有する。スケジューラは、ハンドオーバを要求しているユーザ装置宛てのデータが、ハンドオーバを要求していないユーザ装置宛てのデータよりも優先して伝送されるようにスケジューリング情報の内容を決定する。
