和老康一起學5G 2022-09-14 發布于陜西

展開全文

在5G網絡中CellGroupConfig IE用于配置主小區組(MCG)或輔助小區組(SCG)。一個小區組(CellGroupConfig)包括一個MAC實體、一組具有相關RLC實體的邏輯信道以及一個主小區(SpCell)和一個或多個輔助小區(SCell)。

一、CellGroupConfig中網絡側為終端(UE)配置參數有:

rlc-BearerToAddModList
rlc-BearerToReleaseList
mac-CellGroupConfig
physicalCellGroupConfig
spCellConfig
sCellToAddModList
sCellToReleaseList

CellGroupConfig IE中還配置有關無線鏈路失敗(RLF)的計時器和計數器及其他信息。

二、CellGroupConfig是在RRC Setup消息之后，通過專用控制信道(DCCH)傳遞給終端(UE)的消息。

三、CellGroupConfig消息實例，網絡在消息中傳輸了RRC Setup中未發送SRB1的內容；
