Abstract
(EN)
Disclosed are a radio communication system, a radio transmission device, a RACH transmission method capable of reducing the important information conflict probability and improve the communication system throughput in a channel transmitted at a random timing such as RACH. In a frame configuration used by the communication system, the number of slots of RACH is reduced by one and the resource for the slot is equally allocated as a resource for a pilot/UE-ID of other slot. This increases the resource amount of the pilot/UE-ID. Furthermore, the resource of the pilot/UE-ID is divided into a plurality of sub slots, which are allocated as resource blocks for respective mobile stations.
(FR)
La présente invention concerne un système de radiocommunication, un dispositif de radiotransmission, un procédé de transmission par canal d'accès aléatoire (RACH) qui peuvent réduire la forte probabilité de conflit entre les informations et améliorer le débit du système de communication dans un canal transmis avec une synchronisation aléatoire telle que RACH. Dans une configuration de trame utilisée par le système de communication, le nombre d'intervalles de RACH est réduit d'un point et la ressource pour l'intervalle est attribuée de manière égale en tant que ressource pour un pilote/UE-ID d'un autre intervalle. Ceci augmente la quantité de ressource du pilote/UE-ID. En outre, la ressource du pilote/UE-ID est divisée en une pluralité de sous-intervalles qui sont attribués en tant que blocs de ressource aux stations mobiles respectives.

 RACH等のランダムなタイミングで送信されるチャネルにおいて、重要情報の衝突確率を低減させ、通信システムのスループットを向上させる無線通信システム、無線送信装置、およびRACH送信方法を開示する。これらによれば、通信システムが使用するフレーム構成において、RACHのスロット数を1つ減少させ、このスロット分のリソースを他のスロットのパイロット/UE-ID用のリソースとして均等に割り当てる。よって、パイロット/UE-ID部のリソース量が増加する。さらに、このパイロット/UE-ID部のリソースを複数に分割して、細分化されたサブスロットを生成し、これらを各移動局用のリソースブロックとして割り当てる。
