Abstract

<P>PROBLEM TO BE SOLVED: To provide a transmitter which supports Localized type transmission and Distributed type transmission in a single system, and minimizes an increase in signaling bit for reporting assignment of resource blocks even if the number of resource blocks increases. <P>SOLUTION: The transmitter assigns either one of a resource block or a distribution type resource block. The transmitter is provided with: a means for configuring first groups using a plurality of continuous resource blocks, for configuring second groups using one or more resource blocks of the resource blocks configuring each first group, and for assigning any one of the first and second groups; a means for assigning transmission data to any one of a frequency block or a distribution type frequency block on the basis of the assignment; and a means for generating control information for a mobile station to which either one of the first and second group is assigned. <P>COPYRIGHT: (C)2008,JPO&INPIT
【課題】1つのシステムで、Localized型送信と、Distributed型送信とをサポートでき、リソースブロック数が増加した場合においても、リソースブロックの割り当てを通知するシグナリングビットの増大を最低限にできる送信装置を提供する。 【解決手段】リソースブロックおよび分散型リソースブロックのうちの一方を割り当てる送信装置に、連続する複数のリソースブロックにより第1のグループを構成し、各第1のグループを構成する複数のリソースブロックのうち1つ以上ずつのリソースブロックにより第2のグループを構成し、第1のグループおよび第2のグループの一方を割り当てる手段と、割り当てに応じて、周波数ブロックおよび分散型周波数ブロックのうちの一方へ送信データの割り当てを行う手段と、第1のグループおよび第2のグループの一方が割り当てられた移動局に対する制御情報を生成する手段とを備えることにより達成される。 【選択図】図3
