Abstract
Description
下りリンクの通信チャネルは、各移動端末装置10で共有される下りデータチャネルとしてのPDSCH(Physical Downlink Control CHannel)と、下りL1/L2制御チャネル(PDCCH、PCFICH、PHICH)とを有する。PDSCHにより、送信データ及び上位制御情報が伝送される。PDCCHにより、PDSCHおよびPUSCHのスケジューリング情報等が伝送される。PCFICH(Physical Control Format Indicator CHannel)により、PDCCHに用いるOFDMシンボル数が伝送される。PHICHにより、PUSCHに対するHARQのACK/NACKが伝送される。
