Description
wtDLPICHSNR=PilotSNR−Delta
として報告されるが、
ただし、pilotSNRは、dBを単位とする受信されたダウンリンクパイロットチャネル信号上の測定されたSNRであり、Deltaは、パイロット送信電力とトーンチャネル送信電力レベル当たりの平均値、例えば、トーンダウンリンクトラヒックチャネル送信電力当たりの平均との差である。いくつかの実施形態では、Delta=7.5dBである。
初期DCCHレポート情報5790は、フォーマット情報5792およびレポート集合情報5794を含む。フォーマット情報5792は、送信される初期レポート集合のフォーマットを示す情報を含む。いくつかの実施形態では、初期レポートのフォーマット、グループ分け、および/または初期レポート集合に入れて送信される初期レポートの個数は、初期レポート集合が、例えば、反復アップリンクタイミング構造に関して、送信される時刻に依存する。レポート集合情報5794は、さまざまな初期レポート集合を識別する情報、例えば、初期レポートで伝達されるDCCHセグメントに関連付けられている、レポートの数、レポートのタイプ、およびレポートの順序付けられたグループ分けを含む。
初期DCCHレポート情報5850は、フォーマット情報5851およびレポート集合情報5853を含む。フォーマット情報5851は、送信される初期レポート集合のフォーマットを示す情報を含む。いくつかの実施形態では、初期レポートのフォーマット、グループ分け、および/または初期レポート集合に入れて送信される初期レポートの個数は、初期レポート集合が、例えば、反復アップリンクタイミング構造に関して、送信される時刻に依存する。レポート集合情報5853は、さまざまな初期レポート集合を識別する情報、例えば、初期レポート集合で伝達されるDCCHセグメントに関連付けられている、レポートの数、レポートのタイプ、およびレポートの順序付けられたグループ分けを含む。
