看LOG學(xué)5G(79)--網(wǎng)絡(luò)為終端配置的小區(qū)組--CellGroupConfig\o"5G"#5G\o"無線網(wǎng)絡(luò)"#無線網(wǎng)絡(luò)\o"RRC"#RRC\o"CellGroupCon"#CellGroupCon在5G網(wǎng)絡(luò)中CellGroupConfigIE用于配置主小區(qū)組(MCG)或輔助小區(qū)組(SCG)。一個(gè)小區(qū)組(CellGroupConfig)包括一個(gè)MAC實(shí)體、一組具有相關(guān)RLC實(shí)體的邏輯信道以及一個(gè)主小區(qū)(SpCell)和一個(gè)或多個(gè)輔助小區(qū)(SCell)。一、CellGroupConfig中網(wǎng)絡(luò)側(cè)為終端(UE)配置參數(shù)有:

rlc-BearerToAddModList

rlc-BearerToReleaseList

mac-CellGroupConfig

physicalCellGroupConfig

spCellConfig

sCellToAddModList

sCellToReleaseList

CellGroupConfigIE中還配置有關(guān)無線鏈路失敗(RLF)的計(jì)時(shí)器和計(jì)數(shù)器及其他信息。

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